There is a special quality to the silence of Tuli. Indeed, it may be disturbed by the whisper of the wind, the rumbles of elephants or the distant echo of a lion’s roar, but beneath those sounds lies a blanket of silence so profound it stills the soul.
In this almost mystical atmosphere, there are strange ephemeral moments where past and present seem intertwined, and the existence of those gone before seems to flit over the red rocks and beneath the towering baobabs. It is a rough and rugged land where bloody history has taken its toll, but concerted effort has restored wilderness to a thriving landscape.
The Tuli Block is a narrow stretch of land in the southeastern corner of Botswana, sandwiched between South Africa to the south and Zimbabwe to the north and east. This strip of land has a colourful history, and the Limpopo River, which forms its southern boundary, has witnessed it all.
The Tuli Block extends 350km along the Limpopo River, southwest of its confluence with the Shashe River. It comprises mixed-use, fenced and unfenced private properties of varying sizes. Some are farmed, some hunted, and many offer photographic safaris. Rustic bush camps are set beneath ancient fever, Ana, nyala and baobab trees, offering budget escapes for intrepid travellers searching for unspoilt wilderness.
In Tuli, the wind carries stories of the past, whispering over rocks and across the vast wilderness.
The Northern Tuli Game Reserve
The most well-known and best-protected portion of Tuli is the Northern Tuli Game Reserve (Notugre) – a collection of 36 private properties to the east of the Tuli Block, including Mashatu Game Reserve, that are jointly managed for conservation and ecotourism. It extends across some 720km2 (72,000 hectares), making Notugre one of the largest private game reserves in Southern Africa.
The reserve is also a cornerstone of the Greater Mapungubwe Transfrontier Conservation Area, which covers nearly 6,000 km2 (600,000 hectares) and centres on the confluence of the Limpopo and Shashe. South Africa’s Mapungubwe National Park is south of Tuli, across the Limpopo River international border, once home to the Iron Age kingdom of Mapungubwe. To the north and east, Northern Tuli is contiguous with the Tuli Circle Safari Area in Zimbabwe.
The History
As might be expected for a region bordering three countries, Tuli is littered with reminders of a turbulent past – from ancient stone tools and San rock paintings to corroded ammunition casings, left over from wars and the passage of hunters.
During the late 19th century, Botswana was part of the Bechuanaland Protectorate under the United Kingdom of Great Britain and Ireland. At the same time, Cecil John Rhodes was looking for a suitable route for his envisioned “Cape to Cairo” railroad and petitioned to have the Bechuanaland Protectorate transferred to his company: The British South Africa Company. Alarmed by the potential consequences of the transfer, Chief Khama III of the Bangwato Tribe travelled to England to petition the Queen. He managed to win her sympathy but agreed to cede what is now the Tuli block to the company so that Rhodes could continue his railway plans. It is quite probable that Chief Khama III also hoped the company’s presence would keep out the advancing ‘Boers’ (a slang term often used for Afrikaans people, but which means ‘farmers’ when translated literally).
Rhodes quickly concluded that building a railway through Tuli would be a logistical nightmare, and his focus shifted to more forgiving landscapes further west. Some of the northernmost battles of the South African War (Anglo-Boer War) played out in the Tuli Block – including the fight at Bryce’s store, the ruins of which lie on Mashatu Game Reserve.
As the dust settled in the aftermath of the war, the British South Africa Company sold off most of the property to commercial farmers. However, the rugged and inhospitable landscape proved to be largely unsuitable for cattle farming and, eventually, landowners began to turn to game farming and ecotourism. Cooperative efforts of conservation-minded owners saw the gradual return and reintroduction of wildlife, though buffalo remain absent due to strict foot-and-mouth veterinary protocols.
The Rhodes Baobab has borne witness to Tuli’s impressive history.
The Scenery
The trees along the riverine areas are an attraction in their own right. Massive, ancient leadwood and gangly apple-leaf trees contrast against the lush dark greens of the majestic nyala and weeping Boer-beans and dense stands of vivid, yellow-green fever trees. Away from the rivers, the landscape becomes less hospitable and more arid, though equally breathtaking. It is dominated by jagged rocks and bulbous baobabs. Famously, Cecil John Rhodes scratched his name into the bark of one of these giants which stands like a sentinel on the Mmamagwa rock formation and is now known as the Rhodes Baobab.
Solomon’s Wall, close to confluences of Motloutse River and the Limpopo, is another of the main geographical attractions – a 30m basalt wall jutting through the landscape on both sides of the riverbed. This wall once formed a natural dam that held back a massive lake, as evidenced by the deposits of several kinds of semi-precious stones.
Cycle, walk, drive, ride, experience
As mentioned, the Northern Tuli Game Reserve consists of an amalgamation of private properties, which means that entry is only through arrangement with one of the multiple lodges. However, the fact that the land is privately owned means that almost anything goes in terms of exploring (provided, of course, that it does not damage the ecosystem). Aside from the traditional game drives led by expert guides, adventurous visitors to Tuli can explore the surrounds on foot or horseback – galloping alongside herds of giraffe or zebra. For the even more physically active, Tuli’s rocky outcrops and networks of dried riverbeds make for exciting and challenging mountain biking opportunities, with the added adrenaline of encountering some of the reserve’s many elephants.
For those looking for a more sedate experience, underground hides present amateur and professional photographers with a unique perspective of the reserve’s waterholes. From the quick dips of the birds on a hot day to extreme close-ups of elephants’ muddy toenails, the low-level photographic hides offer something entirely different to the safari experience.
There are various accommodation options to suit most budgets, some intimate and rustic and others geared to more luxurious tastes.
The wildlife viewing in Tuli is spectacular, not just in terms of the variety of animals but because the extraordinary scenery creates the perfect backdrop against which to view them. Elephant viewing is best between January and March when large herds of 100-300 individuals gather. The dry season between April and November offers the best nocturnal viewing of less common species like brown hyenas, honey badgers, African wild cat, aardvark and even aardwolf. This period also offers the best predator viewing because water resources are limited to the deep pools and waterholes.
The reserve is open to surrounding areas, so the elephant population has sufficient space to thrive. and Tuli is said to have some of the highest densities of elephants anywhere in Southern Africa. While the reserve is not home to buffalo or rhino, it supports healthy populations of the three big cat species, and deep pools in the rivers are home to pods of hippos and large numbers of crocodiles. Recently introduced painted wolves (African wild dogs) are a rare sighting.
As a transition zone between the Kalahari Desert and Lowveld bushveld, Tuli offers varied and exciting birding opportunities, with over 350 recorded species. The large riverine trees hide Pel’s fishing owls, and the kori bustards (Botswana’s national bird) pick their way through the grasslands while lanner falcons swoop through rocky valleys.
The Land of Giants
The Northern Tuli Game Reserve is often affectionately referred to as the Land of Giants, a name which it lives up to in so many different ways. It is home to the largest antelope species (the eland), and large herds of elephants crisscross its dusty paths. Ancient baobabs, ecosystems in their own right, dominate the extraordinary vistas and the landscape, with its outcrops of red rocks, resembles a giant’s playground.
Listen closely beyond the silence in Tuli. You may just hear the echoes of the history that played out in a rugged, somewhat inhospitable, but infinitely wild and beautiful land.
A new pack of endangered African painted dogs has been released into the iconic Hluhluwe-iMfolozi Park (HiP), managed by Ezemvelo KZNWildlife, with support from Wildlife ACT and the Endangered Wildlife Trust. This is an important milestone in the conservation of the most endangered carnivore in Southern Africa. There are an estimated 3,000-5,000 individuals left in the wild, of which only around 550 live in South Africa.
Painted dog conservation in Hluhluwe-iMfolozi
Established in 1895, HiP is the oldest proclaimed reserve in Africa. It is most famously known for helping to save the white rhino from extinction. However, a lesser-known accomplishment is the integral role the park has played in saving the African painted dog.
During the Population and Habitat Viability Assessment Workshop held in 1997, the plight of the painted dog was laid bare. At the time, the only functional packs were thought to be in the Kruger National Park. The workshop’s main objective was to boost painted dog numbers through the ‘Managed Metapopulation and Range Expansion Project’ and, in so doing, create a second viable population outside Kruger.
The project continues to capture and transfer individuals between reserves to mimic natural dispersal and colonisation events. These transfers are fundamental to ensuring good genetic flow in the metapopulation, reducing inbreeding and safeguarding individuals from disease outbreaks and persecution while searching for new mates.
Due to its large size (90 000 hectares at the time) and conservation record, HiP was chosen as the first reserve to receive painted dogs back into KwaZulu-Natal (KZN). The first pack of nine arrived in 1980. Since then, Ezemvelo KZN Wildlife has had great success in boosting painted dog numbers. The park’s population grew to 85 individuals by 2017.
This success has allowed HiP to be a primary contributor to the South African Wild Dog Metapopulation Strategy, with several single-sex cohorts being moved off the reserve to supplement and build new founder populations around South Africa. These relocation operations (50%), coupled with a number of natural dispersals (15%), natural deaths (30%) and human-wildlife conflict (5%) have led to a recent decline in the local population.
Through these natural and anthropogenic events and in line with the HiP’s management approach, the parks’s wild dog population is currently in a phase of rebuild, consisting of 19 animals. These individuals will now form the foundations of a new and genetically resilient population.
The Mbhulunga pack before and after release into Hluhluwe-iMfolozi
The Mbhulunga Pack
The new pack, aptly named the ‘Mbhulunga Pack’ after the area where they were held in a boma, was composed of five males brought in from Tswalu Kalahari Reserve and four females which naturally dispersed from the Maphumulo Pack in the Hluhluwe section of the park. The Tswalu males brought a much-needed injection of new genetics to the area.
Initially, the males and females lived in two adjacent compartments of a predator holding facility (or boma) in the iMfolozi section of the park. This passive bonding method allowed the dogs to get to know each other through the separating fence. Over time they began to sleep on the central fence line and greet one another through the wire when they woke up.
Once the monitoring team were comfortable with the interactions, they opened the interleading gate and the males and females formed a cohesive pack. They spent another few weeks in the boma before being released into the park. While the pack was in the boma, the Wildlife Act iMfolozi monitoring team completed daily checks, maintenance of the fence and feeding.
All nine pack members are fitted with tracking collars to enable daily monitoring of their movements, behavioural dynamics, ecological influences, disease, snaring incidents and any other human-wildlife conflict issues. The information gathered allows for informed decision making – both at the reserve and the species level.
Following their release, the Mbhulunga Pack has moved north into the Hluhluwe Section of the park, into the natal range of the pack’s females. Wildlife ACT’s monitoring teams based in the Hluhluwe and iMfolozi sections will continue to work closely with Ezemvelo KZN Wildlife Management to monitor the progress of the fledgeling Mbhulunga Pack.
The future
‘HiP remains an ideal setting for ecological research and information gathering on these endangered species, and so contributes to their effective management and overall conservation strategy,’ says Dave Druce, park ecologist – Hluhluwe-iMfolozi Park.
The survival of painted dogs depends on how they overcome competition for resources from lions, leopards, spotted hyenas and crocodiles. Other potential threats include injuries from pursuing prey, disease outbreaks (rabies and canine distemper) and human-wildlife conflict. Hopefully, the Mbulungas will mitigate these challenges, establish a territory and raise pups of their own to boost HiP’s painted dog numbers and strengthen the genetics of the species countrywide.
This project is a partnership between Ezemvelo KZN Wildlife, Wildlife ACT and the Endangered Wildlife Trust. It is supported by generous contributions from the Hans Hoheisen Charitable Trust, the Gabrielle Faickney Charitable Trust and a group of passionate individuals, the Jocks of the Bushveld.
The Convention on the International Trade in Endangered Species (CITES) is one of the largest and oldest conservation and sustainable use agreements in the world. The treaty was ratified almost half a century ago, designed to control the trade in plant and animal species to avoid over utilisation. Naturally, times have changed since the treaty was initially conceived, and there are many instances where antiquated systems have failed any kind of conservation agenda. A recently published article by experts in sustainable use delves into these weaknesses and cautions against changing a species’ CITES listing without carefully considering the complicated set of conservation implications.
CITES listings determine where a species fits into one of three appendices of increasing regulation and restriction. The trade in species on Appendix I is all but banned except under exceptional circumstances, and more stringent restrictions apply to species in Appendix II than Appendix III. (For a more detailed explanation, see What exactly is CITES and how does it work?) However, under the treaty, the decision to list is based on a simplistic set of biological and trade criteria that relate little to the potential impact of such a decision.
The one-dimensional assumption of the treaty is that more stringent trade regulations automatically result in conservation benefits. However, the authors argue that this is not always supported by evidence or experience.
So, when should a species be considered for an Appendix I listing? The article argues that this is relatively uncomplicated where international trade is a significant threat to an endangered species; the species is threatened across its range; international trade plays no positive role; and where a realistic, achievable strategy for conservation is established.
However, there are other scenarios where a listing on Appendix I may fail to improve or even hinder conservation efforts, such as:
When a species is threatened by drivers other than international trade – for example, by climate change. The restriction of trade income to local communities could reduce cooperation in conservation efforts and see increased human-wildlife conflict.
The conservation status of an animal varies considerably across its range. Though split-listings are possible under CITES (where a species receives different listings in different countries), this has been discouraged.
Unsustainable trade will persist despite its illegality. According to the authors, where a thriving illegal trade exists, an Appendix I listing will only be effective if accompanied by well-funded and robust management interventions. The trade in rhino horn is an example of how a powerful and established illegal trade, facilitated by corrupt governments may make an Appendix I listing more of a token gesture.
Here, the authors’ argument is not against the listing of a species on Appendix I but rather that the consequences are often unpredictable. Real-world complexities are seldom considered when making a decision. An untested assumption forms the listing basis, but the outcome is often continued illegal and unsustainable trade devoid of any monitoring or management tools.
The article also suggests that Appendix II, which allows for regulated trade, is not utilised to its full potential, given the flexibility to tailor management options to local contexts. As in the case of Appendix I, increased trade restrictions may help conservation, but they may also come at no advantage and high cost. The example used by the authors is the recent listing of the giraffe in Appendix II. Legal international trade does not pose a significant threat to the species, but habitat loss, civil unrest and illegal bushmeat hunting are key drivers in population declines. The authors question how CITES trade controls will benefit the conservation status of giraffe, even though the public widely hailed this as a conservation success.
Thus, the article proposes three critical changes to the CITES listing decision process:
The development of a formal mechanism for consideration by parties of the likely consequences of the decision. This would entail careful consideration of the practical effects of the decision, rather than reliance on the baseline assumption. The listing criteria and process would need to be overhauled but would mean that listing decisions are not made as futile gestures of conservation concern.
Broadening the range of criteria used to make listing decisions and basing these on the best available information. This would include the use of conservation-based, scientific information and socio-economic sciences.
The implication of the input of local communities living alongside wildlife. Given that local people disproportionately bear the socio-economic costs of trade decisions, they need to be included in the decision-making process. This is a moral issue, but it is also a pragmatic one – effective decision-making requires insight and information from every stakeholder, particularly those with a field-level perspective.
Wildlife trade is not a one-dimensional process taking place in a vacuum – it involves a complex overlap of social, economic, cultural, and ecological elements. No doubt CITES has failed to evolve as needed in the past 50 years, but, equally, the State Parties have failed to drive the necessary change for CITES listing. Instead, they have fallen back on oversimplified assumptions that do not accurately reflect realities on the ground.
The article concludes that a failure to reform the treaty “risks CITES being stuck in a 1970s conception of conservation that ignores complexity, fails to achieve its objectives, and satisfies only a set of constituencies with little responsibility or impact on field-level conservation. The question is not if these modernisations will happen, but when and how. This is a matter of strategic vision that needs to be addressed with urgency and commitment if CITES is to avoid senescence, and mature into a potent and effective conservation regime, well-equipped to address contemporary conservation challenges.”

I find myself confused and at odds with what I understood about the possible origins of Covid-19 after reading this well-constructed article. I am no scientist and cannot fully grasp the many layers of technical analysis, but I can follow an argument, and I do have a good bullsh1t radar. I never bought the conspiracy theories about the intentional release of a human-made virus, and I do/did favour the theory that this horrible pandemic originated in the wildlife markets of Wuhan, China via a natural zoonotic process. But now I realise that there is at least another potential causal theory on the table.
Was Covid-19 unleashed on us by human error – a mistake by scientists who have been mandated to engineer a virus that could potentially wipe out humanity (to protect us from that exact risk)? The ramifications of this option are chilling, to say the least. The author Nicholas Wade is a gifted science writer, but he is not an expert virologist, and what he is saying is being refuted in parts by expert virologists. But then the theory of a natural zoonotic virus from the Wuhan wildlife markets has also been refuted by certain scientists. At the very least it’s good to consider all possible explanations until we find the answers.
Whatever the truth, it’s unlikely that Africa’s wildlife industries (including tourism) will recover fully for several years – if not longer. What are the chances, do you think, that the powers that be will deflect some of the enormous financial resources that they spend daily on weapons, natural resource extraction and space travel into healing our home planet?

From our Editor-in-Chief
African safari….the idea conjures all sorts of images: Denys and Karen flying over the Mara in a Gypsy Moth; a lion roaring atop a rock as he surveys his singing, dancing prey at dawn; a gargantuan tusker framed by the snow-topped peaks of Mount Kilimanjaro. It is to the last of these iconic imaginings that we turn our attention this week. In our first story below, you can stimulate your post-Covid wanderlust with the wonders of Amboseli National Park (and the greater Amboseli region).
Our second story below is good news. Amboseli, like most conservation areas in the world, is not safe. Some pillock decided that growing avocados there would be a fantastic idea. Yes…avocados. In a semi-arid region that attracts thousands of tourists intent on seeing the wilderness and supports thousands of local pastoralists. Well, the local Maasai herders (who live in relative peace with the Amboseli wildlife) and some conservationists decided that this avo farming malarky wouldn’t fly. They banded together, and, for now, the avo people must go and ply their trade elsewhere.
Our third story below is important. So many people on both sides of the trophy hunting debate spend their days yelling moth-eaten arguments at each other across an ideological chasm. While numerous human beings are allergic to actual science, those who seek real data will have a hard time finding it. Many of the arguments by both sides of the hunting war are usually not supported by hard data, often because the relevant research has not been completed.
Now you can relax and enjoy the start of your weekend with a delightful view of Africa at her most spectacular in this week’s Photographer of the Year selection (enter here) there are only two weeks to go. I would suggest you enjoy it with a calming piece of music, a late lunch and the rest of the afternoon off.
While you are wondering what to do with the afternoon I’ve granted you, check out our video of the week. It’s a Google Earth timelapse from 1984 until now of anywhere on earth you care to look – see how we are changing our home.
Our Photographer of the Year 2021 is open for submissions, with cash prizes of US$10,000 for the overall winner and the two runners-up. They and their partners will also join our CEO Simon Espley and his wife Lizz on the ultimate private safari in Botswana.
There is ineffable magic about spending time in the company of elephants. Nothing else in the world compares to the ethereal emotions felt in their presence – a complex awareness of ancient wisdom and profound intelligence. Of all creatures, elephants perhaps best epitomise a wild sense of the divine. Nevermore is this the case than in Amboseli National Park, where these imposing animals stand against the backdrop of ice-capped Mount Kilimanjaro – one of the most iconic images of Africa.

The Park and the broader ecosystem
Formerly Maasai Amboseli Game Reserve, Amboseli National Park covers just 392 square km (39,206 hectares) in Kajiado County, Kenya. However, the park is a core part of the much larger Greater Amboseli ecosystem (also termed the Amboseli-Tsavo-Kilimanjaro ecosystem or various iterations thereof). This massive area of some 8000 square km encompasses Amboseli, Chyulu Hills, Tsavo East and West, Mount Kilimanjaro National Park, and everything in between. Africa’s tallest mountain, Mount Kilimanjaro, is just 50 km to the southeast in neighbouring Tanzania and its looming form dominates the Amboseli skyline on clear mornings.
Apart from its contribution to the scenery, Mount Kilimanjaro has shaped Amboseli’s habitat and wildlife in more fundamental ways. The constant supply of melting water from the mountain’s glaciers flows off the slopes and sinks below ground before rising through the porous soils in Amboseli to create freshwater springs. The result is that while Amboseli itself is relatively arid with low rainfall averages, some of the park is dominated by species-rich marshes, with Enkongo Narok, Ol Tukai, and Olokeya the three largest.
Exciting animals abound. Clockwise from top left: cheetah on the hunt; a male lion on patrol; the iconic shot everyone wants; a spotted hyena making soup
The western section of the park also encompasses part of a dry, Pleistocene lake basin. Within this basin, Lake Amboseli is typically dry except during heavy rainy seasons, when it fills with shallow, alkaline water accompanied by a pink flush of opportunistic flamingos. Away from the lakes and marshes, the park is characterised by sparse vegetation and dusty volcanic soils. The name Amboseli is a corruption of the Maa word ‘Empusel’, which translates roughly as “salty, dusty place”.
On the outskirts of Amboseli, there are several conservancies dedicated to conservation and tourism. These increase the available protected land considerably while offering the discerning traveller a more exclusive experience. The conservancies are supported by the Amboseli Ecosystem Trust, which was established to maintain the larger ecosystem and reduce human-wildlife conflict as wild animals move along ancient migratory paths between the various formally protected parks.
Elephants everywhere
Thanks to the combination of sparse, arid vegetation and the readily available water in the swamps, Amboseli offers spectacular wildlife viewing despite its relatively small size. However, the park’s most celebrated residents are the elephants, present in high densities and sporting some of the largest body and tusk sizes in Africa. Elephants are everywhere in Amboseli, revelling in the waters of the marshes, treading dusty pathways led by a trusted matriarch or, occasionally, posing against the backdrop of Kilimanjaro for awe-struck, camera-wielding tourists.
This alone is sufficient to send visitors home elated, having garnered a new appreciation for Africa’s largest land animal, but the elephants of Amboseli have a further claim to fame. Many of these herds and bulls have been the subjects of the longest-running study of elephant behaviour in the wild. The Amboseli Elephant Research Project, initiated by Cynthia Moss and Harvey Croze and operated by the Amboseli Trust for Elephants, has centred around researching and monitoring the elephants of Amboseli for five decades. The life histories of individual herds have been painstakingly documented across generations, contributing immeasurably to our understanding of elephant behaviour and the bonds within and between herds.
The story of Echo, the matriarch who led her family for over forty years before her death in 2008, captivated people worldwide and changed perceptions around elephants’ complex emotional lives. Her family are still the subjects of ongoing research and remain permanent fixtures around the park’s centre. Tim, a bull elephant who died last year of natural causes, had a penchant for trouble. He also gained considerable fame as a ‘super tusker’ – as has Craig, another gentle giant. Amboseli and Tsavo’s elephant populations are some of the last genetic repositories of Africa’s great tuskers.
While elephants may well be the main event, the park’s other creatures never fail to provide a stirring, supporting performance. Lumbering hippos wallow in the shallows of the marshes and lakes during the day, emerging to mow their way through the park as the heat dissipates. Herds of zebras and wildebeest dominate the plains, while shy gerenuks nibble their way around the legs of towering giraffes.
In the past, Amboseli’s predator populations, particularly lions, have born the brunt of human-wildlife conflict and resentment born of the park’s complex history. Fortunately, comprehensive conservation programmes and work with local communities are showing results. While throughout Africa, lion populations have plummeted, the lion numbers in Amboseli have grown consistently over the past decade. Visitors are now regularly treated to sightings of Africa’s largest cat.
Amboseli’s unique blend of semi-arid savanna and marshlands attracts various birds, and over 550 species (including, miraculously, once, a shoebill) have been recorded in the region. Time spent around the marshes could well reward a keen-eyed birder with the pale flash of the endangered Malagasy pond heron in between the leggy egrets, herons, and grey-crowned cranes. Away from the water, the grasslands obscure the vocal Pangani longclaws, and the vachellia woodlands hide dry country species like the steel-blue whydahs and Von der Decken’s hornbills.

Given the extraordinary wildlife sightings on offer and the best views of Kilimanjaro in Kenya, it is unsurprising that Amboseli is Kenya’s most popular safari destination after the Maasai Mara. The high tourist time coincides with the dry season and arguably the best wildlife viewing as the animals congregate around available water. However, this does mean contending with higher costs and visitor densities. The two rainy seasons – the short rains from November to December and the long rains from March to May – can make traversing the park and spotting wildlife tricky. That said, the scenery is arguably at its most spectacular with the dampening of the dust.
Weather-wise, Amboseli is typically hot and dry, and the park’s proximity to the Equator ensures relatively consistent temperatures. Naturally, sun protection is a must, as are malaria preventative measures.
Lots of wild safari activities and accommodation for most budgets in Amboseli
As a national park, Amboseli is subject to certain restrictions necessary to safeguard its ecological integrity. Normatior (also known as Observation Hill) is one of the few places where tourists can exit their vehicles and soak in the park’s atmosphere. Rough-hewn stairs lead to the top of Amboseli’s highest point, which offers astonishing views of the surrounding marshes and lakes, and, on clear days, Kilimanjaro. However, for more intrepid travellers, neighbouring conservancies are not subject to the same constraints (due largely to their more exclusive nature). Here visitors can explore through guided night drives, on foot or even on horseback. Naturally, this comes at a cost. A stay in one of the private conservancies is typically more expensive (and luxurious) than the national park’s more budget options.
The polarised debate between anti- and pro-trophy hunting advocates is almost invariably incendiary and centred around far-reaching claims and emotional responses, from whether or not recreational hunting benefits specific species to its impact on local economies. The debate is seldom informed by available research, at least in the public sphere. Now a new study analyses half a century’s worth of scientific literature on recreational hunting. It concludes that little is directed at answering the most critical questions in the hunting debate despite the extensive existing research.
Historical research
The authors of the new study set about analysing over 1000 peer-reviewed papers focused primarily on the recreational and trophy-hunting of large mammals between 1953 and 2020. The majority of historical research had been conducted in North America, Europe, and Africa. [Editorial note: the research includes trophy hunting as a category of recreational hunting]. The study identifies seven dominant topics commonly discussed in recreational hunting literature, including:
Ecological, evolutionary, and population consequences of selective harvesting;
Population dynamics in response to hunting, including assessments of survival rates, reproductive rates, and population trends;
Hunting as a source of and management tool for invasive alien or conflict species;
Health and toxicological dimensions of hunting;
Social dimensions of hunting, including hunter attitudes, identities, and preferences;
Economic, social, cultural, political, and ethical dimensions of hunting
The authors show that there is a significant bias towards mammal species over birds in previous research, and eleven of the twelve most commonly studied species are large mammals. In an African context, the lion was the fifth most popular subject of such research, while the leopard claimed the eighth spot.
The distribution of studies focusing on the recreational hunting of specific species
The impact on species populations in Africa
For around a third of the species studied, the conclusions on the impact of trophy hunting on the population numbers of specific species were highly variable. This was likely due to the diversity of studied locations and times. Trophy hunting was linked to population declines of lions in certain regions (such as Zambia, before the trophy hunting ban) and shown not to have caused population declines in others (in Mozambique’s Niassa, for example). The same disparities applied to leopards and elephants.
However, there was no evidence of any negative impacts of recreational hunting on population abundance for the remaining species. The authors warn that due to the limited amount of available research and the fact that so many studies returned inconclusive results, this should not be interpreted as evidence of sustainability. According to the authors, while many studies focussed on the impact of hunting on the ecology and evolution of target species, fewer assessed the effects on animal population numbers.
The impact of recreational hunting on the population abundance of targeted species
The impact on ecosystems, local economies, and livelihoods
One of the most common arguments in support of recreational hunting is that it protects wild ecosystems over alternative, less eco-friendly land uses such as agriculture or mining. In addition, the revenue can theoretically aid conservation initiatives, support human livelihoods, and be fed back into local communities. This is a matter of considerable debate.
Historical research seems to indicate that in much of Southern Africa, in particular, the loss of recreational hunting would negatively affect both conservation initiatives and local livelihoods. However, hunting operations in West and Central Africa have been less successful in this regard, and the cost of establishing, maintaining, and protecting hunting areas seems to be prohibitively high.
Notably, the authors emphasise that even though these are some of the most pressing academic and societal questions, there is surprisingly little research or evidence to inform the argument either way. While there is a considerable body of research quantifying the revenue drawn from hunting, few studies followed through by documenting the benefits (or lack thereof) to conservation and local communities.
For the future
The new study provides important insight into how previous research on the impact of recreational hunting has been conducted and directed. Naturally, given that it was drawn from over 1,000 different studies conducted across the globe, the conclusions are extensive. However, the essence of the study boils down to the fact that we urgently need further research to understand the effects of hunting and address the unknowns that define the current debate.
To this end, the authors put forward several suggestions for future research, including:
Assessments of the impact on species’ populations in diverse contexts;
The interactions between recreational hunting and other anthropogenic threats such as habitat loss;
Investigation of the impact on less charismatic species, including non-targeted species (for example, the effects of hunting large carnivores on prey dynamics);
Empirical evidence on whether or not hunting increases the quantity and quality of ecosystem conservation;
Investigating the links between hunting revenue and conservation initiatives/support of local communities;
Assessment of the moral complexity of recreational hunting and its impact/benefits for people living alongside wildlife. In particular, whether hunting creates sufficient benefits to incentivise conservation in local communities.
A dearth of empirical evidence will only perpetuate the circular arguments prevalent in public discussions on recreational hunting. The urgent need for focussed research to address the current unknowns is patently clear, especially in the face of increasing opposition to the practice on ethical grounds. Whatever the future holds for recreational hunting, it needs to be based on a solid understanding of the ‘influence of local social-ecological dynamics on hunting outcomes, and the voices of the people co-existing with wildlife’.

My heartful thanks to Minister Creecy for issuing a firm commitment to rid this wonderful country of the SCOURGE of the captive lion breeding industry (our second story below refers). The insidious tentacles of this rotten crime against lions permeate deep into our wildlife industry, and this will be no easy process – but at least she has now got the ball rolling.
THAT SAID, I have the following observations:
1. Expect the evil ones to find LOOPHOLES that will allow them to continue after cosmetic changes;
2. Others will simply operate illegally and increase the MAFIA-style methods to avoid jail time (rhino horn and lion bone combo?);
3. Some will MOVE their operations to other countries;
4. The existing caged lion populations in South Africa will likely be DESTROYED – although the most likely process will be agonising deaths as they are abandoned by an industry that operates on zero compassion. Or maybe many will be moved to accredited sanctuaries – time for the animal rights movement to DIG DEEP to fund this lengthy process?;
5. This government strategy of cleaning up this obviously rancid aspect of the wildlife industry is most likely building blocks for plans to expand the HUNTING industry as a contributor to a sustainable conservation future. This quote from the report refers: “‘The development of a national approach for increasing the opportunity, quantity and quality of hunting the five iconic species in wild areas of South Africa…”. Watch that space.
Lastly, a SHOUT-OUT from team AG to Craig Foster and the crew of ‘My Octopus Teacher’ for winning the Oscar!

From our Editor-in-Chief
‘…the vuvuzela has been used to mitigate lion conflict…’ When I read that for the first time, the coffee I was drinking emerged from my nose. I imagined the King of Beasts’ horrified, incredulous visage as an enraged rural villager charged, blasting on the world’s most tuneless instrument. On the Chobe River, the human-lion conflict continues. However, there is hope, and, as our first story below explains, some good people are coming up with innovative solutions (including plastic trumpets) to help humans and lions live in peace.
This week is a lot about lions – which is good, after all, we need more lions. Believe it or not, Panthera leo used to be the most widely distributed mammal on the planet. In our second story below, the South African government has taken the first steps to ending the national disgrace that is captive lion breeding. Once you’ve read the AG story, perhaps peruse the full report (600 pages). If your life is too short to wade through the whole thing, I can recommend the goals and recommendations that start on page 278.
And that’s a neat segue into our third story below – a remarkable, horrifying and, if you’re a South African, embarrassing expose of the lion bone trade. The story and accompanying trailer will show you, sometimes in ghastly detail, just how imperative it is that our government does something to end captive lion farming and the bone trade. Kudos to the brave filmmakers for the risks they took to expose the cruelty in South Africa and the markets in Southeast Asia.
After all that heaviness, it’s time to take a deep sigh, relax with a tipple and peruse this week’s selection for our Photographer of the Year. It’s a beautiful tribute to our magnificent continent. Not much time left to enter (entries now closed) if you’d like a chance to win 10 000USD and a glorious safari to Botswana.
For your second Friday aperitif, our video of the week showcases the Kalahari Desert in the rainy season – a thousand shades of incongruous green with gobsmacking wildlife to match.
An agribusiness planning to operate an avocado farm in the Amboseli region – a water-stressed landscape of southern Kenya famous for its elephants – has lost its license after local Maasai and conservationists joined forces to protest the plans.
Kenya’s National Environment Management Authority (NEMA) revoked the license it gave to KiliAvo Fresh Ltd after questions about how the developer assessed the environmental impact its farm would have on the local ecosystem.
NEMA said concerns included: the proposed farm was in a wildlife corridor; that it violated official plans that zone the area for livestock and wildlife, not cultivation; and that the developers failed to consult widely enough on their plans.
Right: the start of the KiliAvo’s avocado farm; left: The farm fenceline (red) and the movements of a collared elephant (blue) in January 2021
Conservationists and communities stand together
Conservationists, including Big Life Foundation and Dr Paula Kahumbu, CEO of Wildlife Direct, worked alongside the Amboseli Land Owners Conservancies Association (ALOCA) to campaign against the farm.
“Big Life commends NEMA for following to the letter the relevant processes drawn up to balance development with environmental protection in circumstances such as these,” said Benson Leiyan, Chief Operating Officer for Big Life.
“The decision to reject KiliAvo’s insistence that it be allowed to continue operations sends a very clear message to anyone considering commercial farming in this area of Amboseli: only sustainable enterprises that fit with local land use plans and that conserve the environment for people and wildlife are welcome.”
The farm sits in a buffer zone of wildlife habitat and Maasai grazing land just east of Amboseli National Park, a magnet for Kenya’s wildlife tourism famed for its herds of elephants grazing with the backdrop of Mt Kilimanjaro.
The proposed farm in the greater Amboseli area
Tourism threatened
In 2019 close to 200,000 people visited the national park, generating millions of dollars for the Kenya Wildlife Service. KWS does not release exact figures.
But the park itself is small – at less than 400 square kilometres. To thrive, the multiple endangered animal species and the population of 2,000 elephants that live there need to be able to disperse and migrate through neighbouring, locally-owned rangelands.
Significant threats pressure this pocket of remaining wilderness in East Africa – habitat loss, agriculture and climate change are the principal ones.
The region is heavily dependent on tourism
Privatisation of communal land
After this previously communal land was subdivided into a patchwork of private titles, conservationists worked with the majority of the new landowners to group their plots into a series of community-owned conservancies.
Members pledged not to fence or farm their land, and in return, gain access to open rangeland to graze their cattle. Conservation and tourism operators pay regular fees for the protection of this crucial wildlife habitat.
However, there are a number of locals who chose not to group their land into the conservancies. Some have sold their land to people from outside the landscape, including speculators and brokers who, in turn, sold plots on to investors.
KiliAvo Fresh Ltd acquired their three plots of 60 acres each in this way, buying from a third party who bought them from the original Maasai landowners. There are no restrictions on buying or selling such plots.
There are, however, restrictions on land use plans agreed by the Maasai landowners’ association, ALOCA, for the immediate area and in the Amboseli Ecosystem Management Plan, for the wider landscape.
The ultimate land planning authority, the local county council, is overhauling its Spatial Plan but currently designates the area for “agriculture”. Initially, this was understood to mean cultivation but the chief lands officer from the council later clarified it was for “livestock grazing”.
This confusion, in part, led to NEMA issuing KiliAvo Fresh Ltd a license in August 2020 to develop 180 acres for growing avocados and other fruits and vegetables. This followed an earlier rejection of the same proposal, prompting critics led by ALOCA and the Kenya Wildlife Service immediately to cry foul when the new application was approved.
Samuel Ole Kaanki, chairman of ALOCA, said: “The majority of us are united against this farm because it could threaten water supply in this semi-arid place, block where we can graze our livestock, and deter tourism investors who pay us to bring visitors to see wildlife. These concerns were not addressed in the EIA, and we were very surprised to learn KiliAvo had been given a license.”
They complained that the license was issued without enough consultation with local people and environmental experts who would have objected, they said, because the farm stands squarely in an area zoned only for livestock and wildlife tourism.

Setting a precedent
Farm operations that encroach on wildlife land disrupt the natural balance of the ecosystem. Boreholes need to be dug for water-thirsty crops like avocados. These wells impact the water table, robbing surface water sources for wildlife and putting severe pressure on the groundwater resources and springs that support tens of thousands of people.
Faced with what it termed “new information and issues” that had come to its attention, NEMA ordered the farm to stop and threatened to revoke its license. The farm appealed that order at Kenya’s National Environment Tribunal (NET). After seven months of hearings, on April 26 the Tribunal dismissed KiliAvo’s appeal citing a lack of evidence or witnesses. The next day NEMA finally revoked the license.
The farm’s owners said their 180 acres would have a negligible impact on the 38,000 acres of habitat in the Kimana Wildlife Corridor. Even if that were true – and it is unlikely – the key issue was that this case would have set a precedent and many other farms could follow, fragmenting the landscape and devouring essential resources like water needed by wildlife, farmers and livestock downstream.
Revoking KiliAvo’s license has been seen as a positive sign that Kenya is listening and seriously considering the health of an ecosystem and the concerns of local communities when dealing with the negative consequences of corporate-led agribusiness.
However, KiliAvo is expected to appeal these rulings. Conservation organisations including Big Life, KWS, the Conservation Alliance of Kenya, the Amboseli Trust for Elephants, Wildlife Direct, ALOCA, and tourism investors will remain vigilant in opposing KiliAvo’s plans for the farm and any other farming development that encroaches on wildlife corridors and pastoralist land use.
“This is not yet the end, we will continue until this farm has gone, and we are sure no others can follow it,” said ALOCA’s Ole Kaanki.
Our Photographer of the Year 2021 is open for submissions, with cash prizes of US$10,000 for the overall winner and the two runners-up. They and their partners will also join our CEO Simon Espley and his wife Lizz on the ultimate private safari in Botswana.

Introduction
The Chobe River lions face an uncertain future with various barriers hampering recruitment, dispersal and immigration. To the north, hostile farmers in the Zambezi region of Namibia are intolerant of apex predators on their farms. In every other direction, fragmented protected areas and human settlements impede lion movement.
The Chobe River stretches from Lake Liambezi (Namibia) in the west to Kazangula in the east, where it flows into the Zambezi. The western section of the river is populated by cattle, goat and small-scale crop farmers. The Botswana-Namibia border, which is the Chobe River, cuts the floodplain, with the majority falling on the Namibian side (Zambezi Region).
The Chobe National Park protects the lions on the Botswana side where they tend to hunt along the river or on the floodplains. They seldom stray too far into the sandveld teak forests south of the river because of the limited prey.
Pride history
In 2017, there were approximately 20 lions on the riverfront: ten cubs, two old males (at least ten years old), a subadult female, and six adult lionesses. In early 2018, the pride swam across the Chobe River to the Namibian side. It was a fatal day. Five of the six lionesses were shot by Namibian farmers. A Chobe guide with his guests watched in horror as a Namibian farmer cut off the lions’ paws and waved them at the tourists. Over the next month, all the cubs died from starvation.
The subadults survived and the remaining adult lioness (called Broken Tail) settled in a small territory of her own around the Serondela picnic site. In October 2020, she birthed three cubs. The two subadults, possibly siblings, were gradually joined by four lionesses from the south. The young male disappeared and was not seen after July 2018. Possibly not coincidentally, about that time, two new males arrived – Caller and Tom-Tom. Scarface, one of the older males, had his leg broken in a skirmish with the new males and the Department of Wildlife and National Parks euthanised him when he took refuge at Chobe Game Lodge. The other old male died in the territory not long after.
Caller and Tom-Tom
The current pride
Two of the lionesses soon fell pregnant. One, Snips, had five cubs in December 2019, and the other, Teddy Bear, had two cubs in February 2020. One cub, called Lost and Found, wandered into the village of Kasane and was rescued by some tourists, who put him at the edge of the park away from people and traffic. His mother found him eventually, and he was safely back with the pride as of November 2020. Another lioness, Small Girl, mated with one of the new males in early 2021.
The two males roam from west to east all along the river, seldom staying with the pride for long. They are very attached and every greeting after separation is marked with joyous, cub-like playing. They have enjoyed an unchallenged three-year run.
Lone lioness – Broken Tail
Broken Tail, the lioness which returned from Namibia after the massacre, remains alone and produced three cubs (most likely sired by Tom-Tom) in November 2020. She occupies a territory opposite Serondela Lodge on the Botswana side of the river. During the green season from late November to mid-April, the vegetation is very thick and she hunts smaller game. In the dry months, she targets buffalo calves when the herds come onto the floodplains.
The northern Chobe Lions are not troubled by hyenas, of which there are very few. Other predators such as wild dog are sporadically distributed but seem to avoid any area that the lions occupy.
Snips (pride lioness)
Threats
The lack of new males indicates a dearth of immigration. Researchers have noted lions at Ngotsaa in Chobe National Park, about 50 km south of the Chobe River. This is the next pride to the south. There are lions in the Kachikau area, 76 km west as the crow flies, but this is a village region. It is apparently not a big pride and is likely struggling to survive given the farming activities and villages.
The Chobe west of Kabulabula sometimes dries up and lions can easily cross to Namibia. North of the border, the Namibian farmers allow their cattle to graze right up to the border and sometimes over it at Ngoma. It is an irresistible temptation to lions and they quickly learn what soft targets the cattle are. The discovery probably encourages hunting forays north over the border in search of cattle.
Once the lions are in Namibia, the laws become murky – Botswana cannot protect them. The Namibian farmers can legally kill lions if their livestock is threatened. The lions, therefore, depend on the goodwill of the farmers – difficult to muster if they have just lost cattle to border-hopping predators.
Broken Tail (lone lioness)
Conflict mitigation
Chobe is part of the Kavango Zambezi Transfrontier Conservation Area (KAZA) which aims to secure the sustainable use of natural resources for both wildlife and local people in a cooperative effort by Botswana, Namibia, Zambia, Angola and Zimbabwe.
In Chobe and the Enclave (comprising the villages of Mabele, Kavimba and Kachicau), WildCRU (a conservation research unit) has been running several human-predator conflict mitigation programmes. Communities are encouraged to kraal their cattle at night in predator-resistant kraals. These kraals are funded and built mostly by WildCRU. Owners must make a small contribution to the total costs and help to erect the structures. WildCRU also employs community guardians from each village who investigate any reports of lion conflict. To date, WildCRU has built 26 predator-resistant kraals in the Enclave. They hope to build a further 20 during 2021.
WildCRU, through Dr Jess Isden, has also introduced a lion chasing programme. By using vuvuzelas and running towards lions, the lions disperse. Astounding and insane as this sounds, the vuvuzela has been used to mitigate lion conflict with some success in parts of Zimbabwe.
Some of the lodges in the area, such as Chobe Game Lodge and Serondela Lodge, have established a compensation scheme for farmers who have lost cattle to lions. Farmers are also rewarded if they can prove they have chased lions back into the park.
In the Zambezi Region of Namibia, east of Ihaha, where the pride spends most of its time, farmers don’t have the same tolerance. There seems to be an unsustainable number of cattle feeding on the floodplain, many of which do not belong to the herders but to owners who send their animals to the area for grazing. There are more than 300 000 cattle feeding on the floodplain between Sedudu and Ngoma. Game is naturally scarce due to human and livestock pressure. Recently, another NGO in Namibia, the Kwando Carnivore Project, has started conflict mitigation work in the area and this will hopefully help protect the lions and other predators.

Conclusion
Lions are a major attraction for tourists and their absence will drastically, negatively affect tourism along the Chobe River.
All the tourism enterprises on both the Namibian and the Botswana sides would like to see better protection for wildlife and cooperation between Namibia and Botswana. Tourism could have long-term benefits for the area. Not only does it create jobs, but it trains people who can form their own tourism-related businesses. Rural communities need to see the potential in tourism without necessarily giving up their farming practices.
Negotiations with various stakeholders in Namibia continue and seem to be bearing fruit. A lion group has been created with several Namibian officials and a few cross-border meetings have seen some commitment from both sides. There are already several lodges on the Namibian side, thanks to the vaunted community conservancy model. The future for the Chobe River lions is uncertain but hopeful.
What is the link between trophy hunting, deadly infectious diseases and traditional Chinese medicine? The not so obvious answer is lions. Paradoxically, these apex predators are now farmed on an increasingly industrial scale in South Africa (note that a recent announcement by the SA government may change this). The estimated number of farmed lions in the country is already four to five times larger than that of wild lions. And there is another paradox – in 2019, the South African government amended legislation to reclassify lions and 32 other wild species as farm animals. Lions, Bones & Bullets (see video link below) tells the astonishing story of how the lion farming industry adapted to survive losing two-thirds of their trophy hunting clients following Cecil the lion’s shooting and the US boycott that followed.
Lions bred in captivity on an industrial scale in South Africa
If trophy hunting was dying out, then what was stimulating the boom in lion farming? Penguin Random House author Richard Peirce and the Jagged Peak Films team went in search of the answer. They discovered that while canned hunting had decreased, a parallel increase in demand for lion bones from Southeast Asia was fuelling demand, leading the South African government to establish an annual quota for lion skeleton exports. Richard followed the lion bone trail from farms in South Africa to street dealers in Vietnam and Laos.
Following the wildlife trafficking trail led to dangerous situations, but the team persisted in their quest for the truth. An undercover informant in Southeast Asia confirmed that lion bones were being imported and passed off as tiger to be used in tiger cake, tiger wine, and various other ‘tiger’ products consumed in traditional Chinese medicine. The filmmakers exposed how easy it is to buy ‘tiger’ or ‘lion’ products, which are supposed to be illegal by international trade laws. Between the South African skeleton sale value and the end consumer price, they discovered a 60-fold increase. These huge profit margins and the fact that it’s cheaper to import a farmed lion skeleton and pretend it’s a tiger than to rear an actual tiger, drive the South African lion bone trade.
Richard goes undercover to investigate the trail of lion parts in Southeast Asia. Clockwise from top left: Richard is offered illegal pangolin scales in Vietnam; Richard is offered illegal ‘tiger wine,’ ‘tiger bracelets’ and a mysterious ‘tiger whip’ in a marketplace in Laos; List of companies that have imported lion skeletons from South Africa to Laos. While tracking down each address, Lions, Bones and Bullets proved that most are front companies for the true importer; Entrance to the office of ‘Societe Mixte de Transport’ in Laos, an import-export company which has imported lion skeletons from South Africa to Laos on behalf of a client.
This timely and groundbreaking film is much more than a straightforward exposé. The threats lion farming and the lion bone trade pose to conservation are tremendous. Richard, the author of several books on wildlife, explains: ‘Lion farming and the increasing sale of lion bones to Asia involve exploitation, cruelty, injustice, misconception, fraud and corruption. They are a threat to wild lion populations. It is mind-blowing in terms of the huge negativity involved and has no redeeming aspects. Lions are a flagship species; what happens to lion populations will be a major factor in determining the future of wild animals in Africa.’
The threats to global public health are even more significant. The world is paralysed by a pandemic that came to humans via wild animals. Lions, Bones & Bullets reveals how shockingly easy it is to legally develop an expanding wildlife farming industry and then transport products that could be infected with tuberculosis, the ‘world’s deadliest infectious disease’. The disease is still South Africa’s leading cause of death.

The world festival premiere of Lions, Bones & Bullets is being hosted by the 60th Monte-Carlo Television Festival in June. The Prince Albert II of Monaco Foundation, competition partners to the festival, is dedicated to environmental protection and sustainable development globally. Olivier Wenden, Vice-President and CEO, notes: ‘Lions, Bones & Bullets sends a clear and vital wake-up call to the world, inviting us to open our eyes and rethink our relationship with nature and wildlife.’
The team behind Lions, Bones & Bullets includes Kiwi director and executive producer Anton Leach, who has filmed in more than 20 countries, including war zones in Iraq, Syria and Gaza. Also from New Zealand is the film’s producer, writer and editor, Jasmine Duthie. Her work focuses on character-driven wildlife stories. Lions, Bones & Bullets is narrated by leading British actor and campaigner Peter Egan (Harry Potter, Downtown Abbey, Chariots of Fire).
Minister Creecy of the Department of Forestry, Fisheries and the Environment (DFFE) today announced that the Government of South Africa will act on the High-Level Panel’s recommendations to bring an end to the commercial captive lion industry in South Africa.
Her announcement accompanied the release of the 600-page High-Level Panel Report, which identified that South Africa’s captive lion industry:
Poses risks to the sustainability of wild lion conservation resulting from the negative impact on ecotourism which funds lion conservation and conservation more broadly;
Does not contribute to the conservation of wild lions;
Carries significant zoonotic risks associated with intensive breeding and keeping of lions;
Does not represent ecologically sustainable use;
Threatens South Africa’s reputation as a leader in the conservation of wildlife;
Provides very little economic activity benefiting relatively few;
Negatively impacts the authentic wild hunting industry;
Risks stimulating poaching and illegal trade.
The majority of the Panel Members recommended that the Minister put in place a process to halt and reverse the domestication of lions due to captive lion keeping, breeding, and commercial use. They also recommended that policy decisions should be made for an immediate halt of the sale of captive lion derivatives, the hunting of captive lions and tourist interactions with captive lions.
“I have requested the department to action this accordingly and ensure that the necessary consultation in implementation is conducted”, said Minister Creecy. “In adopting the recommendations, it is important to indicate that the key outcomes for the country will include… the ending of certain inhumane and irresponsible practices that greatly harm the reputation of South Africa and the position of South Africa as a leader in conservation”.
She did not, however, address the Report’s recommendation that the DFFE establish an independent committee to formulate a process for the ethical and humane euthanasia of the lions currently in captivity, in consultation with captive lion breeders and keepers, and other stakeholders.
The Minister’s announcement also references the Panel’s recommendations regarding the safeguarding of rhinos in South Africa in the future. Her announcement acknowledges that South Africa protects the largest component of the global rhino population. As such, the country should play a global leadership role in their conservation. As such, the Government will make no further proposals to CITES for trade in rhino horn until certain conditions are met, including developing a global consensus on the legal international trade in rhino horn.
The High-Level Panel was established on the 10th of October 2019 after the then Portfolio Committee on Environmental Affairs requested the DFFE to initiate a policy and legislative review to put an end to captive lion breeding. The Panel comprised 25 individual members, including experienced conservationists, ecologists, hunting industry representatives, wildlife ranching experts, animal welfare scientists, traditional leaders, and a representative of the captive predator industry. They were tasked to “review policies, legislation and practices on matters related to the management, breeding, hunting, trade and handling of elephant, lion, leopard and rhinoceros”.
The Panel’s goals and recommendations are based on a vision of “secured, restored and rewilded natural landscapes with thriving populations of elephant, lion, rhino, and leopard, as indicators for a vibrant, responsible, inclusive, transformed and sustainable wildlife sector”.
The Report also expresses concerns over the listing of wildlife under the Animal Improvement Act. It warns that the potential intensification of management practices poses significant welfare risks that will exacerbate the current challenges being experienced. While the Minister makes no reference to this in her announcement, she states that South Africa will be adopting a One Welfare approach to wildlife welfare. (The ‘One Welfare’ approach highlights the interconnections between animal welfare, human well-being, and the environment.)
In a joint media statement, Blood Lions and World Animal Protection, two organisations at the front of the fight against the captive lion industry, “congratulate the Minister on these bold steps and offer their full support in developing and implementing a responsible phase-out plan in order to ensure that the commercial predator breeding industry is successfully closed down in South Africa, once and for all.”
The comprehensive 600-page report, including the minority opinions on captive lion breeding and rhino management, can be accessed here. The relevant recommendations regarding the captive lion industry can be found on page 328.

Last week we published an incredible gallery by Kenyan guide and Photographer of the Year entrant James Nampaso – of lions targeting a mom giraffe and her tiny calf. Like many of you, I suspect, images like this toy with my emotions – although of course I respect the necessity of this brutal process playing itself out in countless ways in the natural world. After seeing the above gallery, Barbara Westbrook from Australia sent us an enthralling video clip of a similar encounter of a few years back – in the same area. Again, such a brave giraffe mom and calf. This time though, the outcome was different – watch the video featured after our stories below.
Speaking of 2021 Photographer of the Year, May is the final month of entries, before we start the judging process in June. Some epic images already submitted are competing for the title, which comes with US$10,000 in prize money and a Botswana safari for the winner and two runners-up + their partners. Please get your entries in now to avoid the usual last-minute rush.

From our Editor-in-Chief
‘When is the best time to go to Africa?’ The safari guide’s eyes roll heavenward. He forces a smile and answers with something like, ‘You do realise that Africa straddles the equator, covers six time zones, is a vast area more than three times the size of the US of profoundly different vegetation, climate, topography, wildlife and home to over a billion souls of unimaginably diverse looks, languages and cultures. Which bit of Africa were you referring to exactly?’. Luckily for our jaded safari guide, we at AG have come to the rescue with a series of four stories about the best times to visit the many fascinating parts of Africa. In our first story below, we cover the most popular safari season of June to August.
A few years ago, I was shooting a short documentary on the Maasai people who graze their livestock (legally) in the Mara Triangle during the quiet season. Even a blind moron with a faulty pinhole camera could have captured gorgeous images of the scene: backdrop of the Mara at sunrise, the Maasai’s colourful clothing and the odd elephant wandering past the cattle. What struck me most, however, was the fact that the herders, contrary to their cliched portrayal in popular media, are not relics of a bygone era. They were chatting on their smartphones and doing banking transactions dressed in shukas and car-tire sandals while whistling at their cattle. These were modern, 21st-century Maasai. In our second story below, Benoît Feron and Anne-Françoise Tasnier travelled to South Sudan to spend some time with the Mundari people; to learn about their cattle culture and photograph their interaction with the 21st century.
Our third story below is exciting. New research by the big hitters of African elephant conservation lead by Jake Wall with support from doyen Iain Douglas-Hamilton and many others, asserts that elephants occupy just 17% of their potential range. Whether we, as a species, can learn to share this land with them is another matter – but there is hope, and there is more space than we thought.
Our Photographer of the Year 2021 is open for submissions, with cash prizes of US$10,000 for the overall winner and the two runners-up. They and their partners will also join our CEO Simon Espley and his wife Lizz on the ultimate private safari in Botswana.
The Mundari tribe is a small ethnic group from the Republic of South Sudan, numbering between 70,000 and 100,000 people. South Sudan, the world’s youngest country, gained independence from the Republic of the Sudan in 2011 after a 21-year civil war. During the war, Mundari militias organised themselves into commando units under the leadership of the present governor of the Central Equatoria State. They fought in Eastern Equatoria, Eastern Sudan, and Darfur.
The Mundari are one of the ethnic groups indigenous to the Nile valley (Nilotic). Their main homeland is approximately 75 kilometres north of Juba, the capital of South Sudan. Their lands are bounded on the east by the White Nile, an important source of water for livestock.
The Mundari follow a mixture of Christian and animistic beliefs, with symbols playing an important role. As for many people in the area, the Mundari culture is transmitted orally in songs, dance, poems and other body expressions that reflect good, generosity, and other core values. Ritual scarification is an important part of cultural identity. Men must undergo initiation rites where initiates live together in nature and spend three months with a village elder, away from the community. The rite of passage to adulthood is completed with V scars cut into the forehead.
Friendly and peaceful by nature, the Mundari are nevertheless armed, like most tribes in South Sudan. Decades of war have made guns ubiquitous and easy to obtain. That said, the Mudari seem to have no interest in warfare – weapons are used to protect their herds from cattle rustlers. Mundari men take up wrestling as a serious hobby from a very young age. They regularly organise wrestling competitions, and the best proponents keep going until they are too old to compete.
Cattle Culture
The Mundari are agro-pastoralists with an economy centred on agriculture and herding livestock. Their famous, massive-horned Ankole-Watusi cattle are considered the ‘kings of the cattle’. They are part of the Sanga family of African cattle breeds which originated over 2,000 years ago from a combination of the Egyptian longhorn cattle of Africa and Zebu longhorns originally from India. Sanga cattle spread throughout eastern Africa, and many different breeds developed. Some studies suggest that the big horns of the Ankole-Watusi are an adaptation to hot climates, facilitating the dispersal of excess body heat.
While elders (from 38 years old) and maternal relatives settle villages with beautiful huts, the youngest (young men and women, teens and children) go to cattle camps to tend livestock, moving according to the rhythm of rainy seasons. This part of South Sudan is extremely vulnerable to drought with low rainfall and high temperatures. Sometimes the herds can number as many as 850 animals, and finding enough forage for such large herds in arid areas necessitates constant movement. At the end of the dry season, camps are pitched around the Nile, the only place still sufficiently green to accommodate the appetite of their livestock.
In Mundari culture, like for many tribes of the region, cattle play an important role in religion, birth and marriage. They are symbols of wealth and power. Every life event includes a reference to cows, the lives of which can be sometimes deemed more important than those of humans. A person’s position in society is established through the ownership of cattle – the size and shape of the horns being the most important features. Traditionally, Ankole-Watusi cows are considered sacred, with an owner’s wealth counted in live animals. Unfortunately, cattle are also the main source of conflict. Clashes seldom arise over common resources such as land but rather over animals and their ownership.
Before the civil war, each Ankole-Watusi was worth as much as $500. This was the reference value used to calculate the bride price paid to a woman’s family. Following the end of the war, the number of middle-aged men in search of wives dramatically increased. This had a direct impact as it doubled the bride price from an average of 20 cows per bride to 40. This inflation has made cattle even more precious and has also increased the frequency of lethal cattle raids.
Cattle camps
In a cattle camp, everyone plays their role. The men lead the cows into the fields during the day and regroup them in the camp before sunset. The women clean and prepare food for everyone. The children clean the ground of the camp every morning by collecting the dung and burning it at sunset. The smoke drives away mosquitoes and also creates a unique atmosphere for photographers.
Ashes are then used as a natural antiseptic to protect the skin of the people and cows from insects and the sun. The Mundari also use ash as talcum to massage their cattle twice a day and as toothpaste for themselves.
Cattle urine is used to wash hands, faces, teeth and bleach hair. The Mundari also drink it in the belief that cow urine infuses purity. They also combine urine with ashes to polish the magnificent horns of the cattle.
At night, music played on horns floats through the camp. The people sing close to the heat of fires until they fall asleep under the stars with the cattle just a few feet away. Sleep is not always easy, and the herders must often protect their livestock from jackals, hyenas and even painted wolves (African wild dogs). The main threat to livestock, however, is from raiders. Indeed, cattle rustling is a common cultural practice among many pastoral communities in East Africa – the Nuer, Dinka and Murle often participate in cyclical raiding.
The future
The Mundari’s apparently sustainable way of life is no doubt changing. Today, young Mundari dream of another life, and it is somewhat incongruous to observe young people looking at the outside world on Chinese smartphones while looking after the cattle. The modern world is on its way, and China is financing and building a highway that will link Juba to Terekeka, the county where Mundari live. This highway is part of the Chinese oil exploitation program in South Sudan, which started even before its independence in 2011. This war-ravaged region boasts 3.5 billion barrels’ worth of crude oil in proven reserves, and petroleum geologists will likely find more in the two-thirds of South Sudan they have yet to explore. Despite the challenges of working in a war zone, China dominates what analysts have assessed to be the third-largest oil reserve in Africa.
The Mundari way of life faces an uncertain future. We believe, however, it will still take years for the traditions we’ve described to change. They remain the basis for the whole social structure of the tribe – despite cell phones and a few other modern conveniences. Cattle and not cash remains the foundation of society in two main ways.
Firstly, cattle is a financial asset – a kind of “mobile bank account”. Most Mundari people keep cattle and sell them to pay for their essential needs, like food or school fees and – possibly most importantly – the bride price. Secondly, cows produce food. Although very seldom killed for meat, their milk and blood are hugely important parts of the Mundari diet.
With the COVID-19 pandemic, world aid for development in South Sudan has slowed. The majority of humanitarian workers are stuck at home. As in other African countries, South Sudan has immense tourism potential, but it will take years to develop the necessary infrastructure. The official political mentality is still much influenced by long years of war, whereas wildlife safaris in neighbouring regions flourish.
We believe that traditional Mundari’ society will remain relatively unchanged for many years to come. Perhaps we might ask whether their relatively sustainable way of life has lessons more widely applicable – lessons we need to absorb before the tide of modernisation changes the Mundari way of life forever.
It goes without saying that humans have significantly reduced the habitat available to elephants across Africa (as is the case for almost every wild species). Though greatly accelerated over the last century, this has been an incremental process and unpicking the strands of our influence to quantify historical and potential animal ranges is a tricky process. Newly published research from leading elephant conservation organisations clarifies the extent of human impact on elephants: Africa’s giants now occupy just 17% of their possible range.
The new paper details how multiple elephant research and conservation organisations pooled over 15 years’ worth of data on the ranges of 229 individual elephants across the continent. The work was coordinated by Save the Elephants and included researchers from the Mara Elephant Project, the University of British Columbia, Oxford University, Colorado State University, the Wildlife Conservation Society, the University of Stirling, and Elephants Alive. It goes to the heart of why long-term research and in-depth understanding of elephant movements are pivotal to elephants’ conservation. “Consistent data recorded over a number of years plays a vital role in our understanding of how elephants adapt to shrinking ranges and variable climatic effects” explains Dr Michelle Henley, CEO of Elephants Alive.
The data were collected at 19 sites across the four major biomes of Africa: Sahel (the border region of the Sahara Desert in the western section of the continent), forest (central), savannah (east), and bushveld (south). When analysing the data, the new study lays out three questions:
How do elephant home ranges vary in size across sexes, species, and biome?
How influential are the following factors on range size?
a. Individual (sex and species)
b. Biotic (vegetation and tree cover)
c. Abiotic (temperature, rainfall, water, slope/gradient)
d. Anthropogenic (human influence and protected area use) factors
How much suitable elephant habitat remains across Africa, and how much of this suitable habitat is currently occupied?
The study demonstrates that elephant range size is affected by multiple factors, including species (forest elephants utilised smaller home ranges than savannah elephants), sex (bulls occupied more extensive ranges than cows in the long term), and resource availability. The elephants were also influenced by tree cover, temperature, rainfall, and the slope/gradient of the area. Most importantly, elephant movements and range usage were impacted by human factors. From the tracking data, elephants in protected areas occupied smaller ranges. The researchers believe that this is part of a human avoidance strategy – the elephants do not feel safe roaming into areas of human habitation. However, some 57% of the current elephant range falls outside these protected areas (as per the IUCN).
The researchers then used this data to inform an elephant habitat suitability model (HSM) across the entire continent. The HSM predicts that elephants could occupy a range of over 18 million square kilometres – 62% of the whole continent. “We looked at every square kilometre of the continent,” says lead author Jake Wall of the Mara Elephant Project in Kenya. “We found that 62% of those 29.2 million square kilometres is suitable habitat.” As adaptable and generalist megaherbivores, elephants would only be precluded from occupying extreme habitats in the Sahara, Danakil, and Kalahari deserts, as well as high mountain tops and, of course, urban centres.
From the range of conditions encountered by the tracked elephants over 16-day periods, an HSM was extrapolated to each kilometre square grid of Africa (shown in green). Currently, 18,169,219 km2 is suitable range for elephants, which is 62% of the whole continent but for extreme deserts, cities, and high mountain tops. Of the HSM, 85% falls outside of protected areas. It was the likely range of elephants two millennia before the present. The current elephant range (orange) is 3,132,238 km2, according to the African Elephant Specialist Group, of which 57% falls outside of protected areas. The combined elliptical time-density 90th percentile ranges (red), of our sample of 229 collared elephants is 72,113 km2. The protected area boundaries (black hatched areas on the inset maps) are from the World Database on Protected Areas (WDPA).
Iain Douglas-Hamilton, founder of Save the Elephants, explains that through the model, “we used the movements of living elephants to tell us where the dead once roamed. This gave us a new line of evidence to suggest how much range has been lost in the last 2000 years”.
In essence, the study confirms that elephants would once have roamed almost the entire African continent – a conclusion supported by both historical, anecdotal evidence and recent genetic studies. The researchers detail how accounts from navigators and explorers from over 500 years ago record the presence of elephants on the Atlantic coast of North Africa and the mountainous and thickly wooded parts of present-day Tunisia. The HSM indicates that the same stretch of North Africa where elephants once roamed remains suitable habitat to this day. An analysis of ivory recovered from a Namibian shipwreck recently showed a massive reduction of elephant genetic diversity in the last five centuries.
The vast amount of data and extensive analysis demonstrates that elephants could spread back to parts of their former range if given a chance. Their habitats have been severely fragmented by fences, agriculture, infrastructure and human habitation and conflict. However, since their potential range is enormous, there is likely still room within parts of this range for peaceful coexistence between people and elephants. In particular, the authors identify swathes of land within the Central African Republic and the Democratic Republic of Congo, whose forests once held hundreds of thousands of elephants, now reduced to fewer than 10,000 remaining individuals. Naturally, the researchers also acknowledge that there are also parts of this identified range where conflict with people would make the return of elephants unrealistic.
Unfortunately, while the elephant range could expand, current trends are moving in the opposite direction. With the human population expected to grow over 25% from 2019 to 2050 (along with the associated increase in human footprint), there is an urgent need for development scenarios that take wildlife (and human) needs into account to secure the long-term survival of elephants. The researchers hope to refine the current model to aid in quantifying human densities and human-elephant coexistence and exploring the connectivity of potential habitats. The study concludes with the following sentiments:
“In the face of increasing human pressures, proactive landscape planning at the local, national, and continental scales are critical, as well as fostering an ethic of human-elephant coexistence if the future of elephants is to be secured. Is that too much to ask, to protect and conserve this signature animal even in a world where human well-being is paramount?”

Last week was ugly. We published a story where scientists estimate the Namibian elephant population to be several times higher than the go-to estimate by several loud keyboard experts. The data and results were peer-reviewed by the IUCN African Elephant Specialist Group. The story unleashed some pretty unfortunate backlash from those whose narrative demands far lower numbers. The backstory is that the Namibian government, like many African governments, supports trophy hunting as a wildlife conservation tool. Now you know that I am no fan of trophy hunting, and I have the scars to prove it. BUT I also believe, as do my team, that science is the framework for effective conservation and that our layman opinions, while being essential tools for dialogue and problem-solving, are ultimately subject to scientific reality.
One hysterical Namibian activist took to social media to drum up echo chamber support from his adoring fans with hurtful fabrications about the veteran conservation journalist. He also laid into AG – and demanded that he be given the raw elephant population data to come up with his own statistics. He of zero relevant qualifications, experience or training. His premise is that observations from his occasional journeying through elephant territory are a more reliable yardstick for Namibian elephant numbers than what peer-reviewed science estimates, and that we (scientists, AG and those who support science) are in cahoots with the Namibian government to kill more elephants.
It is what it is.

From our Editor-in-Chief
When I started guiding, too many years ago than I care to admit, showing my guests a kill was the ultimate goal. I’m not sure why – perhaps it was because so many nature documentaries climaxed with a takedown. The first time I saw the light leaving the eyes of a terrified impala ram with a leopardess’s jaws clamped around his trachea, I wasn’t sure I wished to see it again. In our first story below, Kenyan guide James Nampaso, treats us to a terrific photo gallery of nature’s sometimes heartrending reality.
In our second story below, we look at new research investigating the use of African grey parrots in traditional west African medicine. The Marché des Fétiches in Lomé, Togo has an astonishing array of wild animal parts for sale, including primate heads, antelope and predator skins, crocodile skulls, dried snakes, domestic dog heads and, of course, birds. A brief google image search will net you a gallery of horrors. Next step is to engage with the sellers and users to come up with sustainable alternatives.
Our third story below is more cheerful. When I was at university, I remember walking past kilometres of shelving full of masters and PhD dissertations thinking, ‘what a waste, no one is ever going to read this stuff.’ While most theses can look forward to long centuries of gathering dust unobserved, one, by an Australian ecologist called Ken Tinley, completed in 1977, resurfaced in the early 2000s. It became the blueprint for the restoration of Gorongosa National Park in Mozambique – it’s a wonderfully unlikely story.
Our Photographer of the Year gallery for this week is another marvel of African nature and human creativity. We are nearing the end of the competition, so either head into the wild and take some snaps or trawl your archives – you might like to win 10 000USD and a luxury safari to Botswana. You can enter here.
Finally, have a look at our video of the week. The Last Horns of Africa is a scary look at what it means to be on the frontline of defending rhino in South Africa – when rangers have to find the courage to become soldiers.

The following is the foreword by Greg Carr to a recently re-published thesis by Dr Ken Tinley who developed an ecological model for Gorongosa National Park in Mozambique. The magnificent thesis was completed in 1977 and remains relevant to this day.
Introduction
I saw Gorongosa National Park for the first time from a helicopter on March 30, 2004. It looked magnificent from above. There were multiple forest and woodland types, grasslands, rivers, a lake, and fascinating geological formations. When we landed, however, it was clear we had trouble. The historic Chitengo Camp lay in ruins—former buildings were rubble. Where tourists once wandered, burned-out vehicles lay amongst grass that was higher than my head. That year, the Mozambican government asked me to help restore Gorongosa, once one of the most popular wildlife parks in all of Africa.
Devastation – historic Chitengo Camp in ruins
Process and response
In the 1960s, scientists said that Gorongosa had the densest abundance of wildlife of any natural area on the continent. This was no longer true. On our visit in 2004, we could drive an entire day and see perhaps one warthog or one baboon. Whatever other wildlife there was hidden in dense forests and had every reason to fear vehicles. Approximately 95% of the large animals were killed during and in the aftermath of one generation of war. How could we possibly restore a landscape of 400,000 hectares (one million acres)?
If we were going to help the Government of Mozambique rewild this ecosystem, we needed to understand it. We needed to create a Park Management Plan.
My very small team and I searched the literature. We found popular accounts of Gorongosa in newspapers and even in the prestigious National Geographic Magazine, dating back to the early 1960s. However, we also needed scientific data. A Harvard University friend found a reference to a doctoral thesis called Framework of the Gorongosa Ecosystem published in 1977 by a Kenneth Lochner Tinley, but not the actual thesis. At the time, Google was a ‘child’, just six years old, and one did not find nearly every imaginable piece of information online. We learned that a physical copy of the thesis existed at the University of Pretoria, South Africa. We used ‘interlibrary loan’ to get that actual document (not a facsimile) sent by the postal service to Harvard and then to us. Helping me was Sydney Kwiram—a brilliant young woman and recent Harvard graduate.
The manuscript’s abstract included this paragraph: “The chapter titled ‘Process and Response’ is the central pivot of the thesis containing the kinetic aspects of geomorphological landscape changes with coevolutionary sequences of biotic communities which change (expand, contract and recombine) kaleidoscopically in space and time, in appearance and content.”
Tourism in Gorongosa before the Mozambican civil war
Wow. I am not a biologist. I wondered if I should return to the friendly, popular newspaper articles about Gorongosa! However, the Tinley masterpiece is written by an incredible hand. It is the kind of literature that a layperson can follow if one reads carefully, even as an expert will gather much more from the same page. Sydney and I devoured this tome. The thesis had chapters on landscape setting, geology, soils, hydrology, climate, wildlife—covering an area in central Mozambique larger than the Park boundaries themselves—under the labels of “Gorongosa Mountain Summit”, “Gorongosa Mountain Slopes”, “Midlands”, “Rift Valley”, “Coast Plateau”, and “Land-sea Junction”. There were graphs of data and hand-drawn maps by Dr Tinley. He did all of this prior to the existence of the personal computer, GPS, digital photography, drones and the Internet. He with his spouse, Lynne Tinley, and their two small children lived in Chitengo (the place where I had landed in March 2004) from 1968 to 1973.
Where on earth is Dr Tinley?
We had the document, but what about Ken Tinley? Was he still alive? Did he live in South Africa? We would not find those answers in 2004.
Meanwhile, our team of scientists used insights from the Tinley thesis as we wrote a proposal to the Government of Mozambique to co-manage and restore Gorongosa. Among many critical observations, Ken Tinley—speaking through his thesis—told us that, in order to save the ecosystem over the long term, Mount Gorongosa needed to be added to the Park. Mount Gorongosa holds one of only two true rainforests in Central Mozambique, full of endemic and near-endemic species. The mountain is the critical source of most of the Park’s surface water during the dry season. At this time, it did not have protected status.
We continued our studies, our visits to Gorongosa, and our talks with the Government of Mozambique. I expanded our team. In 2005, on one of the luckiest days of my life, I met Vasco Galante. Vasco became the Director of Communications for the non-profit ‘Gorongosa Restoration Project’. He is a human connector: he makes friends, then he becomes friends with their friends. He remembers everyone, every encounter, every event. We call him ‘Vascopedia’. Vasco’s records tell me that we found Ken Tinley in 2005. I sent him an email (which, of course, Vasco saved) on November 28, 2005, that says: “We are in communication with Dr Tinley (who now lives in Australia), and we have his thesis, which you will enjoy. I’ll ask Bridget to send you a copy.”
“In communication with Dr Tinley” actually meant that we had found an email address for his spouse Lynne (from someone who knew someone) and contacted her. Lynne is equally brilliant and is Ken’s lifelong teammate. She is an artist of Nature. She wrote Drawn from the Plains, a book about living in Chitengo Camp, Gorongosa Park’s headquarters, for five years. The book includes her original artwork. We located a copy.
I remember reading my first email reply from Lynne. I now felt that the legendary Gorongosa of the 1960s was no longer just a storybook place to read about in articles. I was talking to someone who had lived there, seen it, smelled it, heard it, and breathed it. Soon, I started receiving messages on Lynne’s email account written by Ken. I was finally talking to the person who had written Framework of the Gorongosa Ecosystem when I was still in middle school.
We corresponded with Ken steadily from 2005 on, sharing ideas and receiving welcome advice. Ecologist Dr Marc Stalmans was a consultant to us and later became Director of Science for Gorongosa National Park. He helped us plan the restoration. “Ken was truly ahead of his time,” Dr Stalmans explains, “applying a landscape ecological perspective well before this approach gained popularity in the 1980s-1990s. Ken manually applied GIS principles before the electronic tool was available. Whereas many studies conventionally only provide a snapshot in time, Ken’s work takes a long term, geomorphic and geo-ecological view of the Park in terms of the formation, evolution and long-term outcome of its ecosystems and constituting components. That’s why the work is still hugely relevant one half-century later. Even more astonishing is that this magnum opus resulted from Ken spending only five years in the Gorongosa ecosystem.”

On top of that, Dr Tinley still found time to sketch landscape perspectives of Banhine National Park in Mozambique and an area next to the Kruger National Park in South Africa that would later become part of the Limpopo National Park. Thirty years later, in the early 2000s, these perspectives became the foundation for the first landscape maps for both parks, which now form part of the Greater Limpopo Transfrontier Conservation Area.
In 1990, well after his five years living in Gorongosa Park, Ken worked with landscape architects in Pretoria. They agreed that the existence of a large number of national parks and nature reserves along the frontier between Mozambique, South Africa, Zimbabwe and Swaziland opened the possibility for multi-national transfrontier resource areas (referenced by Dr Stalmans above).
It was exciting to think that existing protected areas could be linked by some of the little populated areas in between—to create one of the largest conservation zones in the world. Rural communities living within the resource areas, as well as the governments of the various countries, would benefit. Ken was one of the originators of the idea that became known as ‘Peace Parks’. President Nelson Mandela, a founder of the Peace Parks Foundation, believed national parks could link nations or regions that had previously seen conflict. His theory: The connected ecosystems would be good not only for wildlife but deliver benefits and peaceful relations to people as well.

We completed the first draft of our Park Management Plan and finalised our co-management contract with the Government of Mozambique. In January of 2008, I signed a 20-year agreement with the Government to co-manage and restore the Gorongosa ecosystem and to bring human development services to the communities that live adjacent to the Park. (That agreement has now been extended to 35 years, until 2043.)
In 2008 we revitalised the ranger team. The team began removing wildlife traps and snares from the Park; some left over from the war. We started a health care programme in nearby communities. We began our first attempts at tourism.
Meeting Ken Tinley
Yet, I had still not met Ken Tinley. I invited him to come and see what we were doing. In October 2010, Ken spent five days with us in Gorongosa.

On the last day of his visit, Ken shared a poignant story with us. This trip was not the first time he had been to Gorongosa since 1973. In 1994, after the war ended, Ken and a man named Paul Dutton, along with José Tello (ex-warden of Gorongosa), were contracted by the IUCN to survey the condition of the National Park. Like Ken, Paul had begun his career as a Game Ranger in the Zululand Provincial Game Reserves and later continued his education to earn a graduate degree in Ecology. They became lifelong friends. In his own small Piper Cub airplane, Paul helped Ken and José perform the first aerial surveys of the vast herds of large ungulates during the first year of Ken’s research in Gorongosa. In 1994, they found what I saw a decade later: no wildlife and destroyed infrastructure.
The Future
The Gorongosa Restoration Team has made great progress from 2010 to 2019. Our rangers removed over 27,000 traps and snares. We reintroduced some species that we obtained from other national parks, such as buffalo and wildebeest from Kruger. But mostly, in a safer environment, the remaining small populations of wildlife were able to increase on their own. In 2018 we conducted an aerial wildlife survey and counted more than 100,000 large animals. (This represented just the fifteen largest species we could count from the air, not the innumerable smaller species that are also thriving.) The press has been kind to us. National Geographic refers to us as perhaps Africa’s greatest wildlife restoration story.

We also made headway on our human development programme in the traditional communities that share the greater ecosystem with the Park. Our after-school Girls’ Clubs keep teenage girls in school and out of child marriage. We help small farmers get better yields on their land. We’re restoring the rainforest on Mount Gorongosa by planting shade-grown coffee. We provide healthcare to more than 100,000 people per year.
This idea that national parks should benefit the local people was one of Ken Tinley’s early insights and it forms the core of our philosophy at Gorongosa Park. But not only that, we also believe that local people should lead the management of these protected areas. They have knowledge and expertise about the healthy functioning of these ecosystems that they have inhabited since time immemorial. and they can combine that wisdom with 21st Century ecological science.
During the Colonial era, most Mozambicans were not allowed to go to school beyond the fourth grade. It is a painful and unpleasant fact, but one we should remember. At the Gorongosa Project, our goal is to empower the next generation of Mozambican scientists who will lead this ecosystem to the 22nd Century. They face of a new set of challenges, perhaps even greater than the wars of the 20th Century – climate change, pollution, invasive species, habitat loss and over-harvesting. Thus, we created a Master’s in Conservation Biology, a two-year program located in the park. It is the only master’s programme in the world taught entirely within a national park. We’ve already graduated our first cadre of twelve Mozambican women and men. The second group will finish at the end of 2021.
We also help Mozambicans continue their education to earn PhDs. Dominique Goncalves, a Mozambican woman who grew up near Gorongosa, is completing her PhD in Wildlife Ecology at the University of Kent in the UK. She also is the Manager of Elephant Ecology at Gorongosa Park. In October of 2018, I travelled with Dominique to Perth, Australia, to meet Ken and Lynne Tinley in their home. The walls of their apartment were covered with Lynne’s original artwork, some paintings of Gorongosa. Ken and Dominique talked for two days. He gave her unpublished notes from his research as the two of them exchanged ideas, passing the torch of Gorongosa science to the next generation.

The African grey parrot (Psittacus erithacus) is one of the most heavily-traded bird species globally, prized for its attractive looks, intelligence and propensity for mimicry. While most trade supplies the exotic pet trade, a new study confirms that grey parrots are also being sold in traditional medicine markets and consumed for belief-based use in some West African countries. Feathers, whole parrot remains, and parrot heads are traded for various medicinal and spiritual uses.
African grey parrots in the wild
According to the study and previous research, over 1.2 million wild-sourced African grey parrots have been traded internationally since the 1970s. The unsustainable trapping and trading of wild parrots, along with habitat loss, has resulted in dramatic population declines across the ranges of both African grey parrots and Timneh parrots (P. timneh). In some countries, populations have declined by as much as 90% over the past 25 years. Though there has been little research into the use of grey parrots in traditional medicine, researchers have now made inroads into understanding the dimensions of this established trade.
Researchers interviewed five vendors at the ‘fetish’ market – Marché des Fétiches – in Togo, West Africa to investigate the purpose and socio-economic drivers of belief-based use. The market is the largest of its kind for belief-based medicine in West Africa, and here wildlife trade is conducted openly, even when certain species are protected by national legislation. The vendors were selected on the basis that they had been previously observed trading parrot parts. The questions asked of the vendors focused on the body parts sold, the purpose and price, the source country, and the species availability.
Their findings suggest that approximately 900 grey parrots were traded over the past ten years in the marketplace. The majority of parrot heads were sold for improving memory and spiritual ‘protection from witchcraft’ and ‘good luck’. Feathers are purchased for spiritual use, ‘attracting clients’, ‘love’, and ‘help with divorce’. According to the vendors, parrot heads were the most valuable parts, fetching several times the value of parrot feathers. Concerningly, the majority of the vendors reported a decrease in the availability of grey parrot parts.
This use of African grey parrots for belief-based practices is not a new phenomenon, and the vendors reported that all purchases over the past decade had involved regular customers. This, in turn, indicates a local demand for the trade in parrot parts beyond the international trade in live parrots. However, the researchers emphasise that further research is needed to understand the relationship between the two different trades, as evidence suggests a degree of connectivity. It is likely that some of the parrot remains in the markets were sourced from parrots that died during the trapping/transport process for the pet trade. (The trapping and trading of wild parrots raise serious welfare concerns and is estimated to have a 40-60% mortality rate.)
Related to the relationship between the two types of trade is whether the increase in scarcity of parrots reflects the collapse of local wild populations or the recent reduction in international trade (precipitated by increased international legal restrictions). The vendors all stated that Benin and Togo were the main source countries for parrot derivatives. Yet, experts believe that wild populations of grey parrots in these countries are negligible or even extinct. The grey parrots in neighbouring countries such as Ghana have also shown a precipitous population decline. If there are small remaining populations, even low exploitation levels would be disastrous and could result in further local extinctions.
As is the case with any wildlife species, it is challenging to assess the impact of belief-based use. As the study acknowledges, aspects of the trade (such as the trade in feathers) may prove sustainable. The authors also emphasise that the study’s intention was not to determine the extent of the trade – the information provided by the vendors may have been either exaggerated or underestimated. Instead, the interviews were conducted to inform further research and direct future conservation efforts. Immediate intervention initiatives could include education initiatives and the provision of herbal alternatives.
The conservation efforts directed at saving the surviving African grey parrot populations are intricate and multi-faceted, involving everything from international trade policy to dangerous anti-poaching and sting operations. While the study identifies the need for further in-depth research into this threat to grey parrots, it is only through understanding the patterns and drivers of the trade that effective strategies can be developed to mitigate its effects.

I watched this trailer for an African-themed movie and was not sure whether to laugh out loud or vomit in the back of my mouth. If you can get past the horrendous type-casting of African people and gobsmackingly misinformed portrayals of predators waiting around every corner to eat you alive – then you are a better person than I. Apparently, there are rhinos in Amboseli (which attack and flip vehicles), and the hyenas there whoop like gibbons when hunting humans. Breathe deeply Simon, move on …
Back to reality, and after a really good wet summer here in the Greater Kruger region, the seasons have turned, and our autumnal grass and woodlands are rapidly turning golden brown as we prepare for a long dry winter. We are heading into the best wildlife-viewing time, and intrepid travellers are taking advantage of Covid-impacted low prices and few tourists. Need I say more?

From our Editor-in-Chief
This week is much about the elephants – one a good news, if rather technical, story and the other, another blight on humanity’s appalling environmental report card. In the first one below, veteran Namibian conservationist Gail Thomson describes exactly how the Namibian government arrived at their population figure of 24 000 elephants. Despite what naysayers might argue, it would seem that Namibia’s elephant population is thriving and increasing. Long may that last.
Our second story below leaves me bemused. Quite how it has taken the IUCN so long to recognise the species status of the forest elephant despite science having known about it for almost 20 years, is beyond me. What on earth have they been doing? With the speed of frozen treacle oozing uphill, the politicians, lawyers and scientists have finally made it official and the news is not good – the forest elephant is critically endangered.
After all that, our third story below should be much more fun and encouraging. Mix yourself a pina colada (yes, I know you’re at work but that might make it taste even better). I’ve always had a fascination with remote ocean islands. This story of Mauritian conservation – pristine beaches, coral reefs, tropical fishes, lush forests, endemic animals and cascading waterfalls – had me yearning to feel the sand between my toes, hearing the drum of the ocean and the primordial sound of the island jungle.
Finally, our Photographer of the Year is heading into the final stages. Please send this link to anyone you know who takes good shots of Africa – they might like to win 10 000USD and a luxury safari to Botswana. Mix another pina colada and enjoy the 14th celebration of our magical continent!
Kenyan guide James Nampaso entered a few startling images of giraffes and lions for our 2021 Photographer of the Year. See his submitted images in this weekly selection. We were interested to know more about what happened, and James submitted the following images and story:
“The event took place in the Maasai Mara ( Olare Motorogi Conservancy) in Kenya. During a morning game drive I saw two female lionesses watching a female giraffe and her calf from the cover of a croton bush. Soon the lions started stalking the giraffes and I told my guests to get their cameras ready. The lions managed to jump onto the calf, but the mother giraffe chased them away. Once the rest of the pride arrived they surrounded the giraffes, and after about half an hour, a lioness managed to jump onto the mother giraffe’s back and so distract her. During that separation, the lions killed the baby while the mother giraffe managed to escape.” James Nampaso
Our Photographer of the Year 2021 is open for submissions, with cash prizes of US$10,000 for the overall winner and the two runners-up. They and their partners will also join our CEO Simon Espley and his wife Lizz on the ultimate private safari in Botswana.
With over 160km of talcum-powder sand beaches, turquoise lagoons, luxury resorts and protected on all sides by an encircling coral reef, Mauritius is an island paradise. That said, there is so much more to Mauritius than just the beach. Away from sunbathing, water sports and busy beaches, the island is a world biodiversity hotspot, a land of volcanic mountains dotted with pockets of ancient forest. It is home to an incredible diversity of wildlife, including some of the world’s most threatened animals and plants. Mauritius is increasingly focusing on ecotourism and, together with several forward-thinking operators, the island has its eye on becoming a world leader in green tourism.

When you live on a small island in the Indian Ocean, you are sensitive to every tiny environmental change that happens around you. As awareness of the importance of maintaining the island’s ecosystem grows, Mauritius is working hard towards its goal of conservation and sustainable tourism. It is this side of Mauritius that I had come to experience on my travels there.
I had been invited to the opening of the Kestrel Valley Nature Reserve, a 200-hectare private nature reserve located in an indigenous Mauritian forest. Previously a deer hunting farm, Kestrel Valley is now under new management and has switched focus to conservation and the protection of endangered species. It serves as the base from which eco-volunteers participate in a variety of conservation programmes. Though the project is primarily targeted at gap-year students and conservation enthusiasts of a generally younger age group than myself (I was, in fact, old enough to be the mother of some of the other participants), I was fortunate enough to experience their hands-on approach to conservation.

The valley is also home to the Mauritian kestrel (Falco punctatus), once one of the most endangered birds in the world but which has since been brought back from the brink of extinction by the concerted efforts of conservationists and scientists. My fellow volunteers and I spent our first few days monitoring and carrying out census counts of the kestrels as well as the endangered Mauritian fruit bats (Pteropus niger – which also roost in the valley). We also took part in alien plant eradication, quite literally weeding in the forest by hand. This particular project, which turned out to be surprisingly rewarding, saw us pulling up and carting out armfuls of invasive plant life to make way for the indigenous plants.

Like most of the Indian Ocean, Mauritius has seen a sharp decrease in its coral reef, primarily due to climate change and aggressive fishing methods. When we had time out from our dry land projects, the volunteers and I got involved with some reef and lagoon conservation projects. We spent a couple of days underwater, gaining hands-on experience in saving the island’s marine environment. Donning masks and snorkels we set off, looking for signs of coral bleaching and invasive species, as well as monitoring some of the island’s critically endangered hawksbill sea turtles (Eretmochelys imbricata).
As we swam through the lagoon, we saw the devastation of previous coral bleaching incidents, times when a sudden rise in water temperatures kills off the coral, leaving it white, desolate, and somewhat depressing.

The following day, we took part in a coral farming project that aims to grow corals and replenish these damaged areas of the island’s reefs. As part of the project, we started the day collecting small fragments of coral from a healthy section of the reef, later transporting them to the ‘farm’. A lot like an underwater garden, the coral farm consists of submerged ‘tables’ that the coral fragments we’d collected were attached to. This attachment process was a bit harder than I had anticipated, and the strong currents tossed me about as I tried repeatedly to get the job done. Eventually, I got the small coral pieces firmly anchored down and hoped they would all flourish!
These coral ‘farms’ form part of vital efforts to save the remaining reefs
On a day off from active conservation, we were given a guided tour of the tiny rocky wildlife sanctuary of Ile aux Aigrettes. Resident scientists offered a series of talks and guided walks around the islet and introduced us to some of its more endangered inhabitants, including the pink pigeon which has been brought back from the brink of extinction, along with the Mauritian kestrel and the echo parakeet (Eretmochelys imbricata). We also saw the rare olive white-eyes (Zosterops chloronothos), the brightly coloured Mauritian fody (Foudia rubra), and numerous startlingly vibrant Mauritian ornate day geckos (Phelsuma ornata) as well as the island’s extensive nursery for indigenous and native plants. The passion of the scientists here was contagious, and we left at the end of the day with a new appreciation of the dedication that goes into conservation, habitat restoration and the saving of species.
Everywhere you look, Mauritius is bursting with colour, like this blue-tailed day gecko (Phelsuma cepediana).
It was time to move on and see what is being done for conservation elsewhere on the island. After a week of ‘work’ at Kestrel Valley, I was invited to Vallée de Ferney to see their impressive plant and animal restoration project. With less than 2% of the indigenous forest ecosystems of Mauritius remaining, Ferney is one of the last nature reserves on the island – a biodiversity sanctuary where some of the rarest plant and animal species on the island are found.
The valley is another old hunting concession that has been turned over in large part to conservation. There is a stunningly beautiful lodge here and, with only four rooms, you have the feeling of having the place to yourself. Sitting by the pool that night, with our feet dangling in the water, we felt like we were in a lost valley, nestled between the mountains with fruit bats flying overhead as the stars twinkled in the night sky.
Chamarel Waterfall – few people realize that these precious ecosystems exist in Mauritius
A highway was scheduled to be constructed through Vallée de Ferney. Fortunately, before work could commence, surveys of the area led to the discovery of several plant species that were either new to science or were thought to have been extinct. Most exciting of all was the discovery of a handful of specimens of the critically endangered Bois Clou tree (Eugenia bojeri). Local protests saw the highway project scrapped, and in 2006, a 200-hectare nature reserve was established in partnership with Mauritian Wildlife Foundation (MWF) to conserve and restore the indigenous forest in the valley.
The Ferney team have already achieved some remarkable progress. Invasive plants have been removed by hand from 10 hectares of the forest so far, and over 30,000 endemic trees have already been planted, with plans to plant an additional 4,000 indigenous trees in the valley by the end of the year. Another rare tree, Le Manglier Vert (also known as the “manglier rouge” – Sideroxylon puberulum), was also discovered to be growing in the valley and is now under protection. There is also a nursery with a stock of over 11,000 native plants, many of which are rare or critically endangered.
Plants are not the only focus at Ferney. 150 endemic birds have been released into the valley, including endangered echo parakeets, pink pigeons (Nesoenas mayeri – which have bred there successfully) and Mascarene paradise flycatchers (Terpsiphone bourbonnensis). There are also 14 or 15 pairs of Mauritian kestrels in the reserve.

Of course, no trip to Mauritius would be complete without a trip to the beach. But even on a beach holiday, more and more travellers are now looking for a commitment to sustainable development and responsible tourism from their intended destination. Lagoon Attitude, a 182-roomed hotel that overlooks one of the largest lagoons in Mauritius on the northern side of the island, has stepped up to answer these needs. Without doing away with all the glamour of a tropical beachside resort, Lagoon Attitude has introduced a swathe of innovations to keep even the most eco-minded guest happy.
The crystal clear waters of Mauritius
In removing all single-use plastics from the resort, the hotel estimates they have eliminated 690,000 items of plastic litter per annum. The introduction of eco-workshops in upcycling ocean waste and a ‘blue net bag’ collection programme encourages guests to collect litter from the ocean. Switching the cleaning products used on their boats to eco-friendly products prevents further reef degradation, as does providing guests with 100% natural, non-polluting, and locally made sunscreen. By providing reusable water bottles, solar water heating and much more, the hotel has embraced the idea of green tourism. Plans are underway to roll out these changes in all eight other hotels in the Attitude group, making an enormous positive impact on the local environment.
Lagoon Attitude offers tourists the chance to enjoy paradise with a clear conscience
In addition, a Marine Discovery Centre within the hotel grounds houses a marine laboratory employing two full-time scientists who work with a consultant marine biologist. The lab is a base for marine research, coral reef monitoring, a coastal mangrove rehabilitation project. It regularly hosts school visits so that local children can learn about and appreciate how unique their island is.
The United Nations General Assembly declared the 2011 – 2020 the Decade of Biodiversity, aiming to promote the benefits of biodiversity, conservation, sustainability, and a vision of living in harmony with nature. As the decade draws to a close, it is initiatives like the eco-focused places I visited in Mauritius, that demonstrate that you can enjoy paradise without destroying it.

Counting elephants is not easy. It takes experience, skill and funding. The good news: elephants are thriving in Namibia. Gail Thomson, veteran journalist and conservationist, delves into the incredibly complex process of elephant censuses.
Based on interviews with Kenneth /Uiseb, Debbie Gibson and Colin Craig
The African savannah elephant was recently classified as Endangered[1] by the International Union for the Conservation of Nature (IUCN), citing a decline throughout Africa of 60% over the past 50 years. Yet in Namibia elephant numbers are increasing and their range is expanding; a testament to sound long-term conservation policies. But how do we know that they are increasing? How do you assess the status of an animal that ranges over thousands of square kilometres with any degree of confidence? I spoke to the experts to find out.
The small four-seater Cessna aircraft is full. The pilot is flying slowly in a dead straight line, maintaining an altitude of 300 feet above ground level. Behind him, two passengers stare intently out the windows; searching the ground between two black rods fixed to the plane’s wing struts. One passenger suddenly calls out: “left, elephant bulls, two,” followed shortly by the other: “right, elephant cows, ten in, five out.” The fourth person in the plane, sitting next to the pilot, decodes their cryptic messages and jots them down on a datasheet.
Once they have reached the end of this straight line (known as a transect) on their GPS, the pilot will turn the plane around, find the next parallel transect line and fly back along it – keeping flying speed and height as constant as possible. They keep it up until they have flown a planned number of transects for the morning, at which point they will return to base for a much-deserved rest. Every day for the next few weeks they will fly many transects each morning and afternoon until they have covered the target landscape sufficiently to estimate that population of elephants.
How do aerial surveys for elephants work?
There is a lot more to aerial surveys than flying around looking for big grey shapes in the savannah. Debbie Gibson, a key team member who plans and co-supervises aerial surveys in Namibia explains, “Before we even start flying, we use our knowledge of the area to identify and map strata that are sub-blocks of the whole area that we can cover in a day or two.” Strata in areas with higher elephant densities are covered with more tightly spaced transects (e.g. 2.5 km apart) than those with lower elephant densities (e.g. 5 km apart). This increases precision in areas with high densities without introducing bias into the overall count.
The strata (top map) are blocks of the overall area that can be covered in a reasonable length of time. Transects (bottom map) are then mapped onto the strata according to the expected elephant densities in each of them – the density of transects matches the expected density of elephants in each stratum. Source: (Gibson & Craig 2019a.)
“Once we get out to the survey area, we run several calibration flights over the airstrip to measure exactly how much of the ground we are seeing from the air,” Debbie continues, “and to ensure that the observers are searching similar widths of ground on either side of the plane using the rods fixed to the wing struts as guidelines.” Besides allowing for calculations of the ground covered, these rods set realistic limits for searching. Although observers can see all the way to the horizon from an airplane, they are highly unlikely to see all of the elephants in that huge, undefined area. Instead, they focus their search on the known area covered between the rods, where they are less likely to miss any distinctive grey shapes.
This small family herd of elephants are counted as “in” the sample area between the black rods.
If the sharp-eyed observers happen to see elephants outside of the defined search area, then they are recorded as “out” elephants – i.e. beyond the measured sample area. These sightings are mapped and their numbers reported, but only the “in” elephants are used in the statistical analyses to generate a population estimate. Surveys are also done in the dry season when the vegetation is less dense and visibility is high to reduce the chances of missing elephants.
Debbie further emphasises the importance of highly experienced observers – “Our regular observers, Ngoni Chitemamuswe and Fungai Muroki, have counted elephants and other wildlife on aerial surveys since the 1990s and have worked with us in Namibia, Malawi, Mozambique and Zimbabwe. Finding such experienced, reliable observers can be difficult for those doing aerial surveys for the first time in other countries.”
Biologists and conservation managers are rarely able to count all of the animals in their area of interest with 100% accuracy, so the more realistic option is to count the animals in a sample of the area and use statistical methods to estimate population size for the whole area. These estimates also give us an idea of how precise they are, which is expressed as our “confidence” in the estimate. In simplified terms, an estimate of 20,000 ± 4,000, for example, tells us that we are 95% confident that the actual number lies between 16,000 and 24,000.
Even with all the detailed planning, experience and analyses in the world, one aerial survey is not particularly useful on its own. Scientific wildlife monitoring of all kinds (by road, air, or even remotely using camera traps) only becomes useful when surveys are repeated many times using the same or very similar methods. While trying to get extremely precise numbers of elephants ranging over huge areas in northern Namibia is nearly impossible, repeat surveys can be used to show a trend over time. Trends are especially important in conservation because they tell us if the population is healthy and growing, or under severe threat and declining.
Namibia’s Ministry of Environment, Forestry and Tourism (MEFT) has conducted aerial transect surveys since 1979. The earliest surveys, however, were not as refined as they are today and important variables (e.g. height above ground level) were not kept constant. Colin Craig has been involved in standardising aerial surveys in Namibia since 1994, having learned these survey techniques while working for Zimbabwe National Parks (the techniques were originally developed in East Africa). “Although our equipment has improved and we have refined our survey design over the years,” he points out, “the surveys done in Etosha and the northeastern parts using the same methods since 1994 are all comparable. The MEFT, therefore, has a fairly good handle on the trends in elephant numbers over time for each of the major subpopulations in the country.”
Aerial survey techniques have thus been developed and refined specifically for counting elephants in Africa’s savannahs over several decades by many different scientists (it is far more difficult to count their forest cousins, which are now Critically Endangered[2]). Colin compiled the best practices generated from scientists’ accumulated experience in 2012[3] for the IUCN’s Monitoring of the Illegal Killing of Elephants (MIKE) project. The Great Elephant Census (GEC)[4] in 2014-15 used these techniques for the first standardised survey of elephants completed in multiple African nations at the same time[5].

Namibia and the Great Elephant Census (GEC)
This is where the story of counting elephants in Namibia becomes strangely controversial. Thinking that Namibia’s official estimates are too good to be true, some commentators have guessed that the number of elephants in the country is much lower than official estimates (e.g. “probably closer to 5,600[6]” – less than a quarter of the official estimate). These guesses are often accompanied with the accusation that Namibia refused to take part in the GEC because they wanted to inflate the elephant numbers for nefarious reasons[7].
In reality, Namibia’s aerial surveys were done at the same time as the GEC in other countries (in both 2014 and 2015) and were coordinated with the GEC’s Botswana survey of 2014 and Zambian survey of 2015. Most of the surveys in Namibia and the 18 countries that were part of the GEC were done using the transect sample method described here (sometimes local conditions favour other methods). Not only were the data collected the same way, but all of this information was sent to the centralised African Elephant Database[8] managed by the IUCN’s African Elephant Specialist Group[9]. A team of independent experts from this Specialist Group reviewed all of the results (including Namibia’s) and collated them for the 2016 African Elephant Status Report (publicly available here,[10] pp. 169-174 covers Namibia).
Since there is a huge variation among African countries in terms of the resources they devote to monitoring and conserving wildlife, the Status Report includes an objective assessment of the quality of the data produced and the status of elephants in each country. Having trawled through the raw data and examined the methods used by aerial survey teams through the years, the expert review panel concluded that for southern Africa: “There is reliable information available for Botswana, Namibia, Swaziland, South Africa, Zambia and Zimbabwe.” And further: “In Namibia the elephant population has increased, notably in the north-east Kavango and Zambezi Regions.” The actual estimate given for the Namibian population in this 2016 report was 22,754 ± 4,305.
Elephant distribution in Namibia from the 2016 African Elephant Status Report (Thouless et al. 2016). Dark green indicates known distribution, light green is the possible distribution, hatched areas are data input zones (i.e. areas from which data were collected, mainly through aerial surveys) and X marks individual sightings outside of their known range.
Considering the above, why was Namibia not included in the GEC’s results, which were published separately from the Status Report? Kenneth /Uiseb, Deputy Director of Wildlife, Monitoring and Research at the MEFT, shed some light on this matter. “Vulcan Inc. [established by Microsoft billionaire Paul Allen] funded the GEC[11] aerial surveys in the other countries on condition that their raw data would be provided to the GEC team for analysis.” He explains further, “but we had our own budget within the MEFT for the 2014-15 surveys, and we trusted our usual team of surveyors to maintain high standards for collecting the data and doing the analyses.”
For many countries that do not have the resources to fund their own surveys, Vulcan’s support was gratefully received and the conditions were accepted. Yet as Mr /Uiseb indicates: “We had no need for external funding and consequently saw no reason to send our raw data to the GEC team for analyses that we could do ourselves. As a member of the IUCN, however, we willingly contributed our data to the African Elephant Database.” Interestingly, the Database itself received support from Vulcan at the time that the 2016 Status Report was published.
The latest elephant numbers and trends
The MEFT commissioned Colin and Debbie to do another aerial survey in the northeastern part of the country in 2019 to update the information on the elephant population in this crucial area. They also completed a survey in the northwest during 2016[12] to update the numbers for this relatively small but important elephant population. Elephant numbers for Etosha National Park are still based on a 2015 survey (published in the Status Report), but long-term trends reveal that this is the slowest-growing population in the country.
The 2019 survey produced two reports covering the western and eastern sections of the northeast, respectively. The western section[13] covers Khaudum National Park, nearly all of Nyae Nyae Conservancy and some parts of other neighbouring communal conservancies (hereafter referred to as the Khaudum survey). The eastern section[14] covers the entire Zambezi Region, including the Bwabwata, Mudumu and Nkasa Rupara National Parks, the State Forest and 15 communal conservancies (hereafter the Zambezi survey).
These maps were produced from the Khaudum (top) and Zambezi (bottom) surveys in the dry season of 2019. Darker green colours indicate higher elephant densities. Source: Craig & Gibson (2019a and 2019b)
The 2019 estimate for the Khaudum survey was 7,999 ± 3,028 and the estimate for Zambezi was 12,008 ± 2,598. The 2015 estimate from Etosha was 2,911 ± 697, while the 2016 northwest estimate was 1,173 ± 681. If we assume that elephant numbers have not changed in these latter populations between 2015 and 2019 (it is more likely that they have grown slightly), we can conservatively estimate the whole Namibian elephant population at 24,091 ± 4,107 in 2019. The claims that there are only 5,600 elephants in the whole country are easily debunked from the observers’ datasheets produced during these surveys. If one includes elephant sightings both “in” and “out” of the sample area, the observers actually saw 10,051 elephants in just a fraction of the total area for which the national estimate was generated.
Since the survey methods were standardised in 1994, the Khaudum survey has been completed six times, Etosha seven times and Zambezi nine times using the transect sample counts described here. Repeat surveys are the gold standard for wildlife monitoring and provide the all-important population trends, which tell us how successful (or not) local conservation efforts have been.
Counting elephants in the northwest is far more challenging than in the northeast, as there are relatively few elephants in a huge area and the mountainous terrain makes flying at a set level above the ground all but impossible. Consequently, counting methods have changed much more in this region than the others, as scientists are still refining their methods to balance cost-effectiveness with accuracy. The most recent count in 2016 employed three different methods that were allocated to different parts of the region based on the ruggedness of the terrain and knowledge of the elephant population. Even though this is the best count thus far for the northwest, it is still the least precise estimate of all the subpopulations. This population makes up only about 4% of Namibia’s elephants, however, so the lack of precision here has little influence on the national total.
Aerial surveys were completed in the four key elephant areas in 1995, 1998, 2004-05, 2011 and 2015-16, thus providing nationwide estimates for each of these points in time. When these estimates are plotted on a graph, we find that the overall trend for the Namibian elephant population during 1995-2016 is increasing. The slope of the trendline that runs through the estimates is then used to calculate an annual growth rate of 5.36%. This is biologically realistic, as elephant population growth rates can be as high as 7% under ideal conditions[15] that are rarely met by free-ranging elephants.
The elephant estimates for each of the nationwide surveys are represented by black dots with the confidence interval shown as lines extending above and below each dot. The black line gives the “best fit” for the data, from which we calculate the rate of increase over time. The red lines show the likely limits within which the true population lies at any time (Source: Draft Elephant Management Plan, MEFT 2020).
Under-counting elephants and transboundary movements
The national elephant estimate of about 24,000 was calculated only for those populations that have been surveyed repeatedly from the air and is therefore likely to be an underestimate. Mr /Uiseb clarifies: “Based on farmer reports[16] to us of conflict with elephants, we know that elephants are expanding their range in Namibia; they are moving into areas that have not been regularly surveyed. National population numbers also exclude elephants in private game reserves.”
Another concern that is frequently voiced is that elephants in the eastern Zambezi Region move freely between Botswana and Namibia. We therefore cannot be certain if the growth recorded for this large population is due to births or immigration, or an unknown combination of the two. Nonetheless, the aerial surveys are always done in the late dry season (September/October), which tells us that the part of the elephant population that usually spends the dry season in Namibia is increasing. Doing surveys in different seasons would only show short-term elephant movements and tell us little or nothing about long-term population health (reduced visibility in the wet season would also introduce counting errors).
Under high poaching pressure, one would expect the elephants to spend less time in Namibia and those that do come over would experience high levels of mortality, which would together result in decreasing numbers. In terms of Namibian elephant conservation efforts, which are especially focused on reducing poaching in this part of the country, the increasing elephant population is good news. This is confirmed by recent poaching statistics, which show that only 11 elephants were killed illegally in 2020[17], down from a high of 78 in 2014.

While there is occasional transboundary movement from Khaudum in the west, the main movements are from the Zambezi population into other KAZA countries (especially Botswana). Source: MEFT (2020) data from WWF-Namibia.
Since conservation policies differ from one country to another, it is important to find out how elephants are faring in each country that contributes to the Kavango-Zambezi (KAZA) Trans-frontier Conservation Area. Nevertheless, a multi-country aerial survey of elephants in KAZA with several experienced survey teams flying simultaneously in their respective countries is high on every elephant conservationist’s wish list.
Conclusion
Elephants are highly valued within African cultures and economies, perform irreplaceable ecological functions, and are loved and revered around the world. Monitoring them to inform conservation action is therefore a weighty responsibility that the Namibian government takes extremely seriously. This is why they commission professional teams of dedicated people who plan meticulously, search carefully for thousands of hours from cramped little aircraft, and finally analyse and report their results with careful attention to detail. This work is an important contribution to our knowledge of elephants, and Namibia’s successful conservation efforts for this endangered species are an example for the rest of the world.
The forests of West and Central Africa are vibrant, impenetrable worlds of their own: breathing ecosystems bursting with life at every turn yet defined by a pervasive sense of mystery. Enfolded by towering trunks, creeping vines and lush ferns, the forests’ enigmatic creatures flutter through the canopies and wander ancient paths in an increasingly dangerous world at the mercy of human impact. Their largest residents, African forest elephants, are close to the brink of disappearing entirely.
As of March 2021, the forest elephant is officially listed as ‘Critically Endangered’ by the International Union for the Conservation of Nature (IUCN).
The world’s smallest elephant is elusive and poorly understood while centuries of persecution have made them understandably mistrustful of humans. Our belated recognition of their species status and desperate plight has left scientists and conservationists scrabbling in a race against time to learn more about these grey forest ghosts.
Quick introduction
The African forest elephant (Loxodonta cyclotis) is one of two African elephant species, mainly confined to West and Central Africa’s forests from Cameroon to the Democratic Republic of the Congo. Roughly 72% of the remaining populations are found in Gabon and the Republic of the Congo. Forest elephants are smaller than their savanna cousins (Loxodonta africana – also referred to as the African bush elephant) cousins. Forest bulls rarely exceed three metres at the shoulder and seldom weigh more than three tonnes. (This compared to a big savanna elephant which may reach close to four metres and weigh over six tonnes.)
Forest elephants consume an enormous variety of plants and are recognised as essential seed-dispersers in forest ecosystems. Scientists have labelled them “megagardeners” of the forests. Their movements seem to be guided by the ripening of fruits, which occurs at different times in different parts of the forest. They seek out minerals to supplement their diets and are attracted in large numbers to the salty waters of the forest baïs. As a result, much of what we know about forest elephant behaviour comes from observations at these large forest clearings.
For now, our understanding of forest elephants is primarily extrapolated from the extensive behavioural research of savanna elephants, though scientists are now more focused on learning about forest elephant peculiarities. By all accounts, their social structure is similar to that of savanna elephants, with the females living in small family herds, which display “fission-fusion” patterns of behaviour. (That is, they are not territorial and will form temporary associations with other herds or individuals for a while.)
The differences (a summary)
The ears of forest elephants are more oval than those of the savanna variety (hence the specific name cyclotis). The tusks are most distinctive, however, growing relatively straight and usually pointing straight down rather than out. The differences are subtle to the inexpert eye and manifest more as a sense of “something different” when images of the two species are viewed side-by-side. A quick way to distinguish between the two is to count the number of toenails: forest elephants have five on their front feet and four on the hind feet, while savanna elephants only have four on the front feet (occasionally five) and three on the back foot. This method is, of course, contingent on being able to see the feet.
One central behavioural and physiological difference is the breeding age and breeding rate. Savanna elephants usually start breeding at around 12 years old and, under optimum conditions, will have a calf roughly every 3-4 years. In contrast, forest elephants only have their first calves at an average age of 23 and have a birthing interval of up to six years. The estimated population doubling time is roughly triple that of savanna elephants. This intensely slow population growth rate means that it would take approximately a century to recover to their pre-2002 numbers (without continued human impact).

Disappearing ghosts
This is a distressing thought, given our current understanding of how forest elephant numbers have declined over the last few decades. There are, at present, no reliable estimates of the overall number of forest elephants throughout their range. Researchers believe that their numbers have crashed by over 86% in the past 31 years. One study revealed that populations had declined by 62% in just nine years, between 2002 and 2011. Before then, centuries of massacres to supply the ivory trade would have resulted in the demise of untold numbers.
In recent years, much of the damage has been caused by a significant rise in poaching, often fuelled by civil unrest in certain countries. According to the IUCN, this remains the single greatest threat to forest elephants. Naturally, most of the poaching is motivated by the ivory trade, and there is a preference in specific markets for forest elephant ivory due to its higher density than that of savanna elephants. In addition, the bushmeat trade likely includes sizeable volumes of elephant meat.
Habitat loss has also been labelled a “silent killer” of forest elephants. The direct loss and fragmentation of their remaining habitats to agriculture, roads and fences are projected to increase in the coming years. Recent research also indicates that climate change may be having unforeseen effects on the physical health of the elephants.
Considering precipitous population declines and irreversible habitat loss, the IUCN’s first official assessment of African forest elephants concluded that they are now critically endangered. (The IUCN also announced the change in the savanna elephant’s conservation status from vulnerable to endangered.)
The third elephant
Given their precarious position, it seems almost bizarre that IUCN recognition of the forest elephant’s status as a separate species took so long. Especially given that genetic scientists had reached that conclusion as early as 2001. Not only are there two different species of African elephant, say recent studies, but they likely diverged between two and five million years ago (depending on the study). This would have occurred around the same time as Asian elephants (Elephas maximus) and woolly mammoths began to diverge. Some researchers argue that the two elephant species may be further removed from each other than lions and tigers and that the split goes back as far as the divergence of humans and chimpanzees.
However, the idea that the forest elephant is not a subspecies of the savanna elephant was far from universally accepted or straightforward, not least because there are known hybrids. Tracing any animal’s evolutionary process through existing genetics is no small task. Hybridisation and gene flow between diverging species are common complications. (Classifications of the African golden wolf and domestic cats/wild cats have faced similar challenges). The matter was finally concluded through a series of genetic studies over the last decade and a decisive report on the limited extent of hybridisation.
The elephant in the room
So, what practical impact, if any, does the forest elephant’s new-found IUCN status have? Especially given that most ground-level research and conservation efforts were essentially treating this fact as a given already? The short-term answer is probably that little will change, apart from temporarily catapulting forest elephants onto media pages across the globe. It also begs the question of how many smaller, less iconic species we lose before they are even recognised as separate species.
However, far from being irrelevant, the forest elephant classification is one of the most high-profile examples of how science, international law, and politics all play a role in the conservation of a species. The classification should allow for more nuanced conservation policies, particularly at an international level, and a complete estimate of remaining population numbers is also likely to be forthcoming. Moreover, it changes how savanna elephant populations are measured since forest elephants were included in past counts and probably accounted for around a quarter of previous estimates.
Given that the IUCN informs CITES’ decision-making (which governs international trade in animals), a distinction between the two species should see increased restrictions to make it harder to launder illegal ivory on the legal market.
Hope for the future?
Most importantly, conservationists hope that this new classification will aid in efforts to protect African forest elephants – long overdue though it may be. It is a frightening thought that upon the official recognition of a new elephant species in 2021, it was immediately classified as critically endangered.
Fortunately, there are protected areas where forest elephant populations are stable, if not growing. Though our acknowledgement of their predicament has probably come too late to ever rectify the damage entirely, perhaps their new ‘Critically Endangered’ label will serve to galvanise the international community into action. These magnificent and unique elephants have paid the price for human greed and conflict, and their value has been undermined by the grindingly slow bureaucracy of international conservation politics. If nothing else, this should serve as a very steep learning curve for the future.

I spent much of last week with a talented and wacky group of photographers in the Greater Kruger area. Our 2020 Photographer of the Year WINNERS and their plus-ones finally got to enjoy the Covid-delayed safari prize – with my soulmate and me along for the ride. Watching them work their cameras was an education in itself, and the fantastic wildlife encounters and fun-filled moments made for an epic safari :-). More later, when we publish a portfolio of their awesome images.
Our video below is really worth watching – is this plan to mine the Okavango region just another hyped-up ‘pump-and-dump’ investor SCAM? Time will tell. Another issue to watch is the threat to open-cast mine the scenically stunning and sensitive Selati Game Reserve. Read this and weep.

From our Editor-in-Chief
The biological travesty that is the Lion King (yes, I know it’s a good story) has created a world of pain for safari guides. Before actual animal behaviour can be discussed, the hapless guide must dissuade his guests of notions like East African dwelling suricates and birds that clean crocodile’s teeth. Let’s not start on the implications of incest that came with Nala and Simba’s nuptials. Possibly the most bizarre addition to the film was Rafiki – a mandrill who had apparently defied science in innumerable ways by coming out of the forests of Gabon to preside over the spiritual well-being of an East African lion pride and its subjects. In our first story below, we set the record straight regarding the fascinating mandrill – a primate who has achieved rudimentary tool use but not discernable contact with the spirit world.
The second story below is not quite so cheerful. It is an op-ed on the Botswanan government’s recent decision to grant 287 licenses to hunt elephants. Part of the reasoning is to mitigate human-elephant conflict, which does not seem logical. We’d be interested to know what you think.
Finally, as the week draws to a close, your escape into the wilderness (albeit digitally) in the 13th week of our Photographer of the Year. Sit back, turn on some tunes and enjoy a brief respite from work – also let it inspire your next trip to the wild! There are only two months left to win that 10 000 USD and luxury safari to Botswana. Here’s how to enter.

MAKEUP MONKEY
The mandrill is a colourful, tool-using, socially complex monkey that lives in groups called hordes in the forests of western Central Africa
Our Photographer of the Year 2021 is open for submissions, with cash prizes of US$10,000 for the overall winner and the two runners-up. They and their partners will also join our CEO Simon Espley and his wife Lizz on the ultimate private safari in Botswana.
One relatively inauspicious day in May 2005, the alpha male mandrill at the “Monkey Islands” exhibit in the Chester Zoo in England stunned the researchers who had been filming his movements for a behavioural study. JC, a 12-year-old Czech-native (or at least, born at Usti Zoo in the Czech Republic), was observed breaking twigs, bark, sticks and wood chips and then using the splinters to clean his toenails. Unbeknownst to him, his primate pedicure was to make headlines the world over: JC had just demonstrated the necessary cognitive ability to create and manipulate a tool for a specific purpose.
Thus, the mandrill joined the elite ranks of non-human primates known to use tools alongside chimpanzees, bonobos, gorillas, and a couple of other monkey species. JC’s pursuit of good hygiene proved that the world’s largest monkey species is more than just a pretty face (in a somewhat flamboyant outfit).

Introduction
The mandrill (Mandrillus sphinx) is a large, almost tailless monkey confined to the tropical rainforests of southern Cameroon, Gabon, Equatorial Guinea, and the Republic of the Congo. Their morphology is superficially similar to that of baboons, so both mandrill and drills (Mandrillus leucophaeus) were once considered to be part of the Papio genus. They have since been reclassified as the only two species belonging to the Mandrillus genus, and researchers have confirmed that they are more closely related to the much smaller mangabey species.
Chacma baboons and mandrills are similar in size – the chacma baboon is fractionally taller and longer, but mandrills are heavier, more compact, and muscular. Mandrills display considerable sexual dimorphism, with the males being almost triple the mass of the females. The ferocious-looking males weigh an average of 32.3kg, with some massive individuals recorded at over 54kg. Like baboons, the mature males sport enormous canines of around 6cm (longer than those of a leopard). These they use to intimidate aspiring rivals and deter potential predators.
Mandrills are omnivorous and feed on over a hundred different plant species, with a particular preference for fruits where available. They also consume various invertebrates, eggs, birds, and reptiles and are known to hunt small antelope and rodents. They spend most of their days foraging on the ground but are equally comfortable in forest canopies, leaping from tree to tree with an agility that defies their considerable bulk.

Multicoloured monkeys
Not only are the males larger than the females, but they are also more lavishly adorned in a spectrum of vivid colours. A strip of crimson runs down the middle of their elongated muzzles and extends over their lips, flanked by a pair of electric blue ridges. A bright yellow goatee spreads down across their chests and up over their shoulders as they mature, blending with tufts of white into an impressive mane. One would think that this alone would be sufficiently eye-catching, but both ends of the male mandrill are equally flashy. Their rainbow rumps are coloured red, pink, blue and purple in what has to be one of the least subtle examples of sexual signalling in the animal kingdom.
Such gaudy displays of colour, while prevalent in many bird species, are uncommon in mammals. Primates are one exception to this rule, and many different monkey species have colourful genitals. However, the mandrills’ colouration is so over-the-top that even Charles Darwin noted that “no other member in the whole class of mammals is coloured in so extraordinary a manner.”
A male mandrill’s ensemble is directly related to his testosterone levels and dominance within a strict social hierarchy. If a male successfully challenges an alpha, his testosterone levels will rise, and the red colours will become more vibrant. His genitals will increase in size, and a gland on the sternum will secrete an odour designed to tempt females. These dominate males are known as “fatted” males. Conversely, a fall from grace will mean the opposite for an unfortunate male as he gradually becomes “nonfatted” once again.
Colourful on both ends
Scintillating sociability
One theory behind the males’ excessive colouration is that it evolved to compensate for exceptionally high competition between males – essentially a method of conflict avoidance in the gloomy rainforest habitat. A group of mandrills is referred to as a ‘horde’ – a large and stable troop consisting of females, offspring, and young males. Research from Lopé National Park in Gabon calculated an average horde size of 620 individuals, with some hordes numbering up to 845 mandrills. One group of researchers counted 1,300 mandrills in one group, making it the single largest non-human primate aggregation ever recorded.
Mandrills are usually found in challenging habitats for bipedal researchers. This, combined with their natural shyness, has made it difficult for scientists to observe mandrill behaviour in the wild consistently. As a result, surprisingly little is known about their social structure. Most monkey troops demonstrate a strict social hierarchy, even between females. Fascinatingly, mandrill experts have yet to discern a consistent pattern of leadership, though it is clear that they have dynamic social networks and that certain females are central to the cohesion of the horde.
The females remain in their natal groups throughout their lives, while the males disperse once they reach maturity at around six years of age. Rather than forming bachelor groups, the males tend to live somewhat solitary lives outside of the breeding season. From June to October, when the females are in oestrus, the males join the hordes and follow their own strict, linear hierarchy. DNA analysis of one horde indicated that the alpha males of hordes had sired 80-100% of the offspring over five years. Disputes between males are usually resolved through posturing and threat displays, but the rare fights between equally matched males are brutal and, occasionally, fatal.
As with other monkey species, grooming plays a vital role in reinforcing the bonds between horde members and winning favours from the alpha males. Both males and females are highly vocal, expressing themselves through various sounds from mighty roars to expressive grunts and screams. Naturally, the bright colouration also serves to emphasise body language cues and facial expressions. The famed “silent bared-teeth face” is just one of their many varied communication methods, with most researchers agreeing that despite appearances, this is not an aggressive body language cue.
Communication with ‘silent bared teeth’
Protected primates?
In the wild, leopards are the mandrill’s main predator, though the likelihood of predation decreases as individuals mature. A large male mandrill is more than a match for most leopards, and males exposed to models of leopards were observed to pace back and forth, baring their impressive teeth in a threat display. Birds of prey, notably crowned eagles, and snakes also pose a threat to incautious youngsters. Interestingly, when presented with a potential threat, these otherwise noisy primates seem to follow a silent cue and noiselessly melt away into the forest canopy.
Despite limited natural predators, the mandrills are listed as ‘Vulnerable’ on the IUCN Red List. While there are no current population estimates available, researchers believed that their numbers might have decreased by more than 30% over the past 24 years. This is partly due to wide-scale habitat destruction across most of their natural range but has been compounded by the more immediate threat of subsistence hunting. Mandrills, particularly large males, are a prime target in the bushmeat trade. They are a long-lived species (with a lifespan of over 30 years in captivity) and are slow to mature, so sustained hunting pressure has had a pronounced effect on their populations.
For the same reasons, the mandrill’s close cousin, the drill, is under even more pressure, and they are now one of the most threatened of all mainland Africa’s primate species. There are believed to be fewer than 4,000 left, scattered in fragmented populations in Nigeria, Cameroon, and Equatorial Guinea. Even though the mandrills and drills are listed under Appendix I of CITES and protected by national legislation across their range, these spectacular monkeys face an uncertain future.
Like gorillas, the mandrill’s best hope of survival lies in their tourism value. Fortunately, the largest populations of mandrills are still flourishing in Gabon’s protected forests. At present, there is only one habituated horde of wild mandrills in southern Gabon. There are plans in place to collar and habituate more hordes as part of a larger move towards improving ecotourism opportunities in Gabon. These last remaining sanctuaries offer eager tourists the best opportunities to meet with one of Africa’s most intelligent, colourful, and fascinating monkeys.
Conclusion
We still have much to learn about mandrills, and unravelling the complexities of their social lives promises to be a fascinating process. As intelligent primates living in enormous social groups, their individual relationships, kin bonds, and hierarchies must be dynamic and complicated. As JC and his clean(ish) toenails demonstrated, mandrills still have the capacity to surprise us and probably will for a long time to come.

What’s in a name? Whenever we refer to ‘painted wolf’ in our stories for what many refer to as ‘wild dog’, we come under heavy artillery fire from a few members of our tribe – even experienced safari-goers and bushveld citizens. Of course, strictly speaking, Lycaon pictus is neither dog nor wolf. Our choice of ‘painted wolf’ is because the name itself is beautiful and conjures up a positive image – whereas for many people, ‘wild dog’ symbolises feral domestic dogs that rummage through city garbage dumps. Read more about this fascinating topic here.
However you refer to these totally fascinating creatures is up to you – so long as you respect them for what they are – apex predators.

In our first story below, some science (albeit from a small sample) shows that relocating cats that come into conflict with human beings is not particularly successful. That said, you’ll be able to find studies that show relocations can be successful. The results are not necessarily conflicting but show how important it is to understand the myriad, nuanced factors that apply to each situation.
Our second story below delves into the fascinating lives of Africa’s 11 species most closely related to man’s best friend. Interestingly, no African canid has ever been domesticated. No doubt that there are some cretinous individuals who’d love to have a fennec fox peeping out of their handbags or a painted wolf jogging with them on the beach. Let’s all make sure that Africa’s wild canids remain just that – wild, forever.
This week’s gallery showcasing the 12th week of our Photographer of the Year is a delight for the senses. It’s a perfect way for those who dream of wild places to escape their urban domesticity for a little while. One of the ways to take yourself into the wilderness is to enter – you could win 10 000 USD and a six-day safari to Khwai in Botswana. Here’s how to take part.
Botswana has granted permission for 287 elephants to be hunted as it gears up for its first trophy elephant hunting season since the ban was controversially lifted two years ago.
With Covid-19 restrictions disrupting last year’s hunting season, 187 existing elephant licences have been tagged onto this year’s 100 licences. The licences were auctioned for up to US$43,000 each.
A variety of other species are also allowed to be shot between April and September, including leopard.
In the face of a global outcry, president Mokgweetsi Masisi reopened trophy hunting in 2019 after former Botswanan president, Ian Khama, banned it in 2014 to conserve the country’s wildlife. Masisi’s government cites that the sport provides a solution to growing human-elephant conflict and provides income for local communities.
“Human-driven habitat loss is fast becoming the ‘silent killer’, almost as big a threat as poaching is to elephants,” says Adrienne West of Political Animal Lobby (PAL). “We are losing Africa’s elephants at a rapid rate, and it is outrageous that one of their most important range states would choose to put their lives up for sale.”
Conservationists and ecological experts dispute hunting as an effective measure against human-wildlife conflict.
“Shooting these elephants will do nothing to reduce the incidence of crop-raiding in farming areas, as most of the killing would take place in trophy hunting blocks that are some distance away,” says Dr Keith Lindsay of the Amboseli Trust for Elephants.
“In fact, shooting elephants could increase tensions between farmers and elephants – they can communicate over many kilometres, and when elephants are killed in one area, the alarm and disturbance would be felt some distance away.”
Elephants are a keystone species, and scientists say there is no ecological reason to reduce their numbers by killing them as they play an important role in ecosystem health and diversity.
Over the past decade, Africa has lost more than 30% of its elephants to ongoing ivory poaching, which is having devasting effects on populations across the continent.
Figures on the CITES international trade database reveal that Botswana’s trophy hunting ban of seven years saved more than 2,000 elephants and 140 leopards from being shot.
Botswana holds the world’s largest population of approximately 130 000 elephants, which share transboundary migrations routes with neighbouring countries, including Namibia and Zimbabwe. During the hunting ban, reports of increased numbers in Botswana suggested that migrating elephants sought refuge in the safety of the then hunt-free country.
Our Photographer of the Year 2021 is open for submissions, with cash prizes of US$10,000 for the overall winner and the two runners-up. They and their partners will also join our CEO Simon Espley and his wife Lizz on the ultimate private safari in Botswana.
Over four years, Kalahari Research and Conservation has monitored the fates of 13 lions known to have killed livestock in rural Botswana. The lions were translocated into protected areas by the Botswana Department of Wildlife and National Parks (DWNP) as part of a management strategy to reduce human-lion conflict. A short communication recently published in the African Journal of Wildlife Research analyses the success of this approach: of the 13 lions, ten died less than a year after release. This research adds to a growing body of evidence that suggests translocating lions does not often reduce conflict and the relocation of “problem” animals is not always a practical solution.
Kgalagadi lion
Human-wildlife conflict is undeniably one of the greatest threats facing the remaining wildlife across the planet, particularly in Africa. It is an intensely complicated issue, and conservationists and philanthropic organisations alike are eternally searching for ways to mitigate the collision between potentially dangerous animals and the people who live on the fringes of protected areas. One such potential solution is the relocation of the escaped wild animal to a place where it is less likely to come into contact with people or livestock. Unfortunately, while this may seem an ideal answer, such efforts seem to have limited success.
DWNP captured 13 lions from areas around the Central Kalahari Game Reserve and the Kgalagadi Transfrontier Park. Both parks are surrounded by Wildlife Management Areas and community lands used for livestock grazing. Before their release into new areas (120km or more from the original point of capture), researchers fitted the lions with satellite telemetry collars to monitor their movements.
Of the 13 lions, ten had died an average of 275 days after release. Six of these died outside of the protected areas, five killed by farmers. The cause of death of the other five was not established. The collars initially provided four locations per day, but scientists increased this to 13 in situations where the lion showed signs of returning to livestock areas. Six of the translocated lions continued to kill livestock and were recaptured and released back into the protected areas. One lion required a third translocation.

In the key, letters after numbers indicate multiple translocations of the same animal.Study area and movement of 4 lions post translocation in the Central Kalahari Game Reserve.
A more thorough analysis of the lions’ movements and activities after their release suggests that targeting groups of adult females could potentially yield higher success rates for translocating lions. However, this could prove problematic in practice and relocating only some pride members may reduce the chances of survival for both the translocated lionesses and those that remain behind. Furthermore, the soft release of predators (that is, the translocated animals are kept in an enclosure for a period of adjustment before release) could also increase the chances of success.
The researchers conclude that their results are in line with similar studies involving the relocation of “problem” animals such as lions, leopards, and cheetahs, mainly where the animals concerned are repeat livestock raiders. These translocations are associated with a high mortality rate and also come with high financial costs. Previous studies involving the relocation of cheetahs indicate a cost of between $5,000 and $7,330 per cheetah translocation. Though the cost was not analysed in this instance, it is likely to be significantly higher for lion translocation, given the substantial size difference between the two cats.
In addition to high mortalities and costs, there is a shortage of suitable areas for translocating lions. Ideally, lions should be translocated to areas with sufficient prey, low lion densities and low poaching levels. Yet, most of the protected areas within Southern Africa have already reached their carrying capacity (itself a testament to the success of conservation efforts in these areas). In addition, translocating lions ideally requires adequate information about the lion demographics within the intended release site, which are not always available to researchers and managing bodies. The effects on the established territories and demographics of the resident lions and the potential spread of the disease are also potential concerns.
Based on these results, the authors argue that translocation/relocation is not an effective solution for addressing human-wildlife conflict. Instead, they suggest that limited available resources should be used to improve livestock husbandry, strengthen livestock kraals, and promote livelihoods beyond farming. Seizing a problem animal and putting it somewhere else may seem convenient and immediate, but overwhelming evidence indicates that it is simply not a practical approach.
Today, 11 African canids, from excitable African painted wolves and shrewd jackals to the tiny fox species, hunt the continent’s desert, alpine grassland, savanna and woodland.
Some 40 million years ago, the first identifiable canid (dog) species, Prohesperocyon wilsoni, arose in what is now Texas. The fossilised remains were classified as Canid partially because of the absent, upper third molars and an enlarged bulla (a hollow structure in the ear). As canids diversified across North America, evolution favoured them with several cursorial adaptations including long limbs and lightweight bodies. They were built to run from the start – a family trait that served them well and has survived in most species. When cooling climates exposed the Bering land bridge, canid ancestors raced, trotted, and slunk across to spread through Asia, Europe and eventually Africa.
African painted wolf or wild dog
African painted wolf (Lycaon pictus)
The most well-known African canid, African painted wolves (wild dogs), are the third-largest extant canid in the world and the largest in Africa. They are coursing, cooperative hunters, with lithe, athletic bodies built for speed and stamina. Their frenetic hunting style exploits panic and confusion, creating fast-paced, exhilarating sightings for those fortunate enough to encounter a pack on the move.
African painted wolves live in tight-knit packs, and there is little so heart-warming as watching pack members affectionately reaffirming their bonds. In social situations, the intimate relationships are expressed in joyful greeting ceremonies and play sessions, accompanied by an endearing array of squeaks, yips and whines. The alpha pair typically monopolises breeding, while the rest of the pack devote their attentions to feeding and caring for both the mother and her pups during the denning period.
They are the only member of the Lycaon genus and the only canid to have four toes on the front foot (they lack a dewclaw). Human persecution, habitat loss and fragmentation, and disease have all played a role in devastating African painted wolf populations. They are currently listed as “Endangered” on the IUCN Red List. Further reading: What’s in a name?
Black-backed jackal
Black-backed and side-striped jackals (Canis mesomelas and Canis adustus)
It is bewildering that the average safari-goer dismisses jackals, intent rather on chasing down traditionally iconic creatures. This is unfortunate because jackals are attractive and adventurous little predators in their own right. Both species are consummate survivors with an indiscriminate palate and a boldness that belies their slender physiques. Jackals are opportunistic omnivores that can quickly and efficiently dispatch invertebrates, birds, reptiles, or even small antelope, but will also readily wolf down fallen fruit or seeds. Furthermore, any animal that dares to snatch the scraps out from beneath a hungry lion’s nose should be entitled to automatic respect.
Jackals are monogamous and territorial, though they may gather in larger numbers when there is a more substantial carcass. Grown offspring from the previous year’s litter occasionally stay and help their parents with subsequent pups – before dispersing. Interestingly, though the black-backed jackal is the smaller of the two, where black-backed and side-striped jackals do occur in the same place, the black-backed tends to dominate interactions.
African golden wolf (Canis lupaster)
The African golden wolf is notable mainly for the insights it has provided researchers of African canid evolution. Until recently, it was classified as an African variant of the golden jackal, which is widespread throughout the Middle East and Asia. Though scientists had long argued for a distinction between the two species, it was only in 2015 that a series of genetic studies revealed that the golden wolf is more closely related to grey wolves, Ethiopian wolves, and coyotes than it is to Asian golden jackals.
Slightly larger than the two jackal species, African golden wolves can catch and kill prey nearly three times their own mass. This is unusual however, and golden wolves tend to confine themselves to smaller prey species such as rodents, birds, lizards, snakes, and insects.
The wolf-like ancient Egyptian deities such as Anubis (the god of death) may have been based on African golden wolves.
Ethiopian or Simien wolf
Ethiopian wolf (Canis simensis)
The Ethiopian wolf has the lamentable honour of being the most endangered carnivore in Africa. Fewer than 500 individuals remain, though this is an optimistic estimate. An IUCN estimate made in 2011 suggested a declining population of just 197 mature individuals.
They are endemic to the Ethiopian Highlands and found at altitudes over 3,000m above sea level, with more than half found in the Bale Mountains. The remaining five populations are isolated and fragmented; threatened by habitat degradation, conflict with humans and diseases carried by feral domestic dogs.
While most canid species are fairly generalist feeders, these beautiful, russet-coated Simien wolves are particularly adept at hunting Afroalpine rodents, especially big-headed mole-rats. The wolves wait patiently until a rodent emerges from its underground burrow before pouncing and digging frantically at the entrance. Interestingly, some wolves form temporary associations with geladas, and research indicates that their hunting efforts are more successful when they associate with these foraging troops. The wolves do not attempt to hunt the geladas, and the primates appear unconcerned by the canids’ presence.
While Ethiopian wolves tend to be solitary hunters, they live in small packs with an established hierarchy and one breeding female, who, when she dies, is usually replaced by one of her daughters.
Bat-eared fox
Bat-eared fox (Otocyon megalotis)
These little canids are the only insectivorous canid species in the world and, despite their common name, are not true foxes (genus Vulpes). Instead, they are the only Otocyon member, set apart by their unusual dentition adapted for demolishing invertebrates. They have up to 50 teeth (most canids have around 42), with reduced shearing surfaces on the molars and unique morphological adaptations which allow for extremely rapid chewing. The majority of their prey consists of harvester termites.
Bat-eared foxes are highly social and live in mated pairs or small family groups that forage, play and rest together. Somewhat unusually, the males take on the majority of caretaking activities where the young are concerned.
They are easily identified by their enormous ears (second only to the fennec fox below), and their scientific name refers specifically to this characteristic: “mega” meaning large and “otus” meaning ear.
Cape fox
Cape fox (Vulpes chama)
The only true fox species in sub-Saharan Africa, the delicate Cape fox prefers semi-arid and arid habitats. In true fox fashion, they are omnivores with a taste for everything from small mammals to seeds and fruit. Though common throughout most of Southern Africa, Cape foxes are nocturnal and seldom seen except in certain reserves where they have become habituated to people.
Though they appear to form monogamous bonds, Cape foxes prefer to forage alone, and the male and female usually only associate during the breeding season. When the kits are born in underground burrows, the male will care for and defend both the mother and young for the first few weeks.
Fennec fox (Fuchs zoo specimen)
Fennec fox (Vulpes zerda)
The fennec fox is the smallest canid species on the planet, weighing less than 2kg. They are perfectly adapted for the aridity and blistering temperatures of their Sahara Desert habitat. Most noticeably, their enormous ears, proportionately the largest of any canid species in the world, help dissipate heat – not unlike the ears of an elephant. Their tiny paws are covered in dense fur to protect against extreme heat and maintain traction on the desert sands. Fennec foxes’ most astonishing achievement is the ability to pant at 690 breaths per minute (over ten breaths per second!) without the expected adverse effects of hyperventilation.
They forage for insects, reptiles, small mammals and birds at night. Plants supplement the diet and aid with hydration.
The fennec fox’s Disney-like appearance has made it a popular exotic pet, even though it is ill-suited to a domestic existence away from its natural desert habitat. Though they are highly social, little is known about the intricacies of their societies, and most behavioural observations have been gleaned from captive individuals.
Pale fox
Pale fox (Vulpes pallida)
Pale foxes are the least studied of all African canids, and little is known about their day-to-day lives or individual numbers. They inhabit the Sahel region of the African continent (the transition zone between the Sahara Desert and savannahs further south). They are distinguished from the Rüppell’s fox (see below) by the black tip on their tails. Just a fraction smaller than the Cape fox, pale foxes are omnivorous and predominantly nocturnal.
Rüppell’s fox
Rüppell’s fox (Vulpes ruepelli)
The Rüppell’s fox is confined to the continent’s northernmost reaches and is distinguished by a white-tipped tail and black markings under the eye. Like all desert-dwelling foxes, they have enormous ears, though not quite to the same degree as the fennec fox. Though the species is widely distributed, there is little available information on Rüppell’s foxes.
Red fox (this is an individual photographed in Europe. In Africa, the red fox tends to be much smaller and greyer than in Europe.)
Red fox (Vulpes vulpes)
Typically associated with the countryside and alleys of European cities, few people realise that red foxes also occur in Africa’s northern fringes. This species is largest of the true foxes, though the southern grey desert subspecies is significantly smaller and less brightly coloured than its European counterparts. These animals are not as well adapted to truly arid areas as other desert foxes and tend to be more common around rivers and oases where there is better access to water.
Barking up the family tree
As the canid ancestors loped their way across Asia and into Africa, they faced competition from the two other hyper-carnivorous predator families: the Felidae (cats) and the Hyaenidae (hyenas). For all predators, the competitive landscape was changing as prey species evolved to run faster through increasingly open habitats. This evolutionary arms race was to shape all three families. The felids came to rely almost exclusively on stealth and ambush, while the dog-like hyenas (distinct from their bone-crunching relatives) all but disappeared (with one exception).
And the canids of Africa? They took on the various forms described above – most are lightweight and fleet of foot and all are bright-eyed, intelligent, and adaptable.
[Editorial note: Blanford’s fox (Vulpes cana) has been recorded on the Sinai Peninsula in Egypt. There is only one record of an individual collected west of the Suez Canal. While it is possible there are resident populations in the African portions of Egypt, this is unconfirmed, and we have thus omitted this animal from our list.]

If social media is an accurate measure of how we communicate as a species, then humankind now ranks virtue-signalling above coalface reality, and we trash distinguished track-records and careers overnight if enough cloistered people feel offended.
In the African conservation context, what does this mean for Africa’s ground zero conservation workers, who don’t have the time or inclination to participate in this race to algorithmic dominance? And what about the Internet-bereft rural people who live amongst Africa’s wild animals and carry the cost of doing so – are they considered by the machine to be irrelevant? Just asking

For many people, bats are not creatures that conjure emotions of warmth, joy or affection. Let’s face it, few of us have willingly cuddled a bat or expressed the desire to do so. Those that have touched one have normally done so while flapping and screaming in an undignified manner while the terrified little chiropterid tried to untangle itself from hair, mosquito net or shirt. Well, cast those irrational fears aside as you read our first story below – a story of the world’s largest mammal migration in the gorgeous Kasanka National Park of Zambia.
Fairies, strictly speaking, are not of African origin. Yes, there are many other sprite-like or magical semi-humans littering African folklore – but no fairies. So it was always unlikely that a European hobgoblin would ultimately be found responsible for the strange, vegetation-free circles that litter parts of the Namib and Kalahari deserts. Well, science has come to the rescue – not fairies but Euphorbias. Our second story below is a fascinating explanation of the strange circles.
Finally, the 11th week of Our Photographer of the Year which carries a prize of 10 000 USD and a six-day safari to Khwai in Botswana. This week’s edition has everything from tiny, sparkling spiders to endless African landscapes – best enjoyed on a large screen with inspiring music in the background. Here’s how to enter.
Our Photographer of the Year 2021 is open for submissions, with cash prizes of US$10,000 for the overall winner and the two runners-up. They and their partners will also join our CEO Simon Espley and his wife Lizz on the ultimate private safari in Botswana.
It’s the end of November, and there are at least 8 million straw-coloured fruit bats (Eidolon helvum) filling the skies at eye level as we perch in our tree-top hide. The annual Kasanka bat migration – the planet’s largest mammal migration – has arrived. It is one of the natural world’s best-kept secrets, and for years this startling sight remained virtually unseen by African travel enthusiasts. It is an animal carnival to astound the senses.
At 3:45am I emerged from my room, rubbing sleep from my eyes, coming face to face with a tiny lesser bushbaby, who stared at me, unblinking with surprise, gripping the spindly branch of a small tree overhanging the deck in front of our room. I’m not sure who was more startled. The bushbaby was simply doing what bushbabies do in the early hours of the morning. I, on the other hand, instead of being tucked up in bed, was off to see millions of fruit bats returning to roost after a night of foraging.
Kasanka is 39 000ha – one of Zambia’s smaller national parks.
Between October and December each year, the bats descend into a tiny patch of evergreen swamp forest inside Kasanka National Park, northern Zambia. The African straw-coloured fruit bat is the second-largest fruit bat on the continent, can have a wingspan up to a metre, and the adults weigh up to 350g. They come to feast on the pod mahogany, musuku, mufinsa, milkwood1 and other wild fruit that appears with the first rains. Scientists are not entirely sure where these bats spend the rest of the year, though they do know that for some of them, it is somewhere deep in the rainforests of the Congo. The bats in Kasanka are at all different stages of the breeding cycle, with some mating, some in various stages of pregnancy, and some with young. It’s known from observation of individual colonies around Africa that these bats are seasonal and synchronise their breeding within the colony, so the diversity seen in Kasanka implies that they are coming from various areas.

Eidolon helvum are predominantly recorded around the edges of equatorial rainforests, but no-one knows as yet if large colonies live deep inside the rainforest. The ecological implications of 3,500 tons of flying mammals arriving over a three month period are profound. Researchers from the Max Planck Institute of Animal Behaviour, who visited in 2019, say they are yet to fully explain the sheer scale of the Kasanka bat migration. Researchers indicate that the number of bats is far greater than the sum of individuals in all known colonies within several thousand kilometres. So it would seem that Kasanka’s special significance to straw-coloured fruit bats is a question that science is not yet able to answer. Hopefully, ongoing satellite tracking research will yield further information on both their migration routes and the species as a whole. While this incredible spectacle is not typically at the top of the traditional safari traveller’s bucket list’, it is a unique experience.
We arrived at Kasanka the previous evening and almost immediately headed to one of the park’s bat hides. We held tightly to the 13m of wooden handrails that wrapped around the trunk supporting the wooden viewing platform. Thirteen metres is not really that high, but it certainly gave a spectacular perspective of the area. Three white-backed vultures perched in a nearby tree. Catching sight of them, my husband, who is not fond of heights, commented that they looked like they were waiting (in vain) for us to plunge to our deaths! A beer for him and a G&T for me restored our equilibrium. We waited and watched as the sun sank.
As the sky turned orange and lightning streaked the sky in the far distance, in a hectare of forest below, the tree silhouettes began to tremble – the bats hanging from their branches started to wake. The branches were so tightly packed with bats that some of them, unable to grasp the branches, were left clinging to their neighbours.
A sunset winged carnival.
As dusk fell, they fluttered off in search of wild fruits, their large, leathery wings filling the air with loud rustling and heavy flapping. As the flock took to the sky, the drooping branches of the bat forest lifted back into place. The bolder bats took to the air first, followed in fits and starts by the rest of the colony. Some headed out, then, appearing to change their minds, turned back, only to try again a few minutes later. The sky was soon filled with chatter as the bats darted in and out of the trees, in a cloud-like mass resembling a giant swarm of overgrown bees.
We waited in our treetop eyrie until it was almost too dark to see the ladder down. By then, the sky was empty; the bats had vanished. The sound of thunder drew closer as we felt our way back down the ladder and, by the light of torches, made our way back to the vehicle. Fat drops of rain began to fall as we drove back to camp.
When morning came, it was only me, the bush baby and my guide Ruston, who seemed to be awake. My husband snored contentedly from under his bed covers. After hot tea and biscuits, I climbed onto the back of the vehicle, wrapped myself snugly in a blanket, and we set off for the tree hide in the bat forest. It was still dark as we walked through the forest with torches in hand, the bats fluttering and feasting in the waterberries above our heads – last-minute snacks before sunrise. As day broke, the bats returned to roost. It was like watching a film of the previous night’s action in reverse but even more breathtaking. Vivid splashes of scarlet, tangerine and gold lit the sky, silhouetting the bats like prehistoric pterodactyls as they flocked, in droves, back to the colony.
They tumbled into the trees pushing, shoving and clambering noisily over one other to find a space to sleep during the day. The area became so overcrowded that I could hear the occasional snap of a branch and then squeaks as a few fruit-bloated Eidolon helvum plummeted, ungracefully, to the ground. Finally, one by one, they settled, and silence descended over the bat forest again. We headed back to camp for breakfast.
Returning to roost after a night out foraging for fruit.
Researchers have found that most of the females in the colony are either pregnant or nursing pups during their migration to Kasanka. The abundant fruit helps support the increased energy they require. They gorge themselves on seasonal fruit, one study finding that they eat up to twice their body weight in a night. By the time they depart Kasanka, the bats will have consumed over a billion fruits! All this provides them with the reserves needed for their long migrations across Africa. No wonder the branches strain and crack under their combined weight, and why, at the end of the bat season, the forest they leave behind looks rather dilapidated.
Even now, scientists don’t really know exactly where the participants in the Kasanka bat migration come from and where they go. At roughly 39 000ha, Kasanka is one of Zambia’s smallest national parks, yet it is home to the world’s largest mammal migration. A small park with a massive treasure.

FUN FRUIT BAT FACTS
– The Kasanka bat migration plays a leading role in the regeneration of forests. The bats’ role as pollinators and seed dispersers is significant, and their ability to travel great distances helps them maintain genetic diversity and connect plant populations across fragmented landscapes.
– According to GPS tagging studies by the Max Planck Institute of Animal Behavior in Germany, straw-coloured fruit bats have the furthest migration routes of all mammals, including other bats, in Africa, travelling thousands of kilometres annually – a distance unheard of in any other fruit bat species.
– Each individual of this species has its own unique scent and call. This allows mothers to find their young in large colonies of millions
– Research by the Kasanka Trust has found that the bats fly on average 50 km from their roost every night to feed in the surrounding forests, covering an area of more than 500,000 hectares!
WHEN TO GO
The bats start arriving in Zambia’s Kasanka National Park towards the end of October. Their numbers steadily increase over the next few weeks. Mid-October to mid-December is the best time for the bats. By the end of December / beginning of January, the forest is bat free.
It’s not just the bats you will see at this time of the year. The rains bring green grass, bright flowers and plenty of migratory birds. Although Kasanka isn’t a place for the ‘Big Five’, you are almost guaranteed to see the rare and special sitatunga.
WHERE TO STAY
Wasa Lodge, located on the shores of a lovely lake, is the closest lodge accommodation for the Kasanka bat migration. There is also a seasonal fly camp, Kapabi, which is well situated. Kasanka also has several self-catering campsites.

Across the deserts of Namibia and the Northern Cape in South Africa, certain areas are dotted with barren sand patches where nothing seems to grow. These peculiar ‘fairy circles’ have captured the imaginations of scientists and tourists with everything, from termites to UFOs, being mooted as potential causes. A new study from the University of Pretoria, South Africa and ITMO University in Russia indicates that dead Euphorbia plants are the culprits for the famous circles. Or, more accurately, the long-term effects of these toxic succulents on soil properties and chemistry.
Fairy circle marked by Theron (a) and remains of E. damarana (b) on Giribes Plain
The multidisciplinary study began six years ago with researchers investigating the impact of Euphorbia species on the circles’ soil properties. They examined the effects on soil chemistry, germination inhibition and antimicrobial activity on rhizosphere bacteria (which many plants need to ‘fix’ nitrogen in a usable form). The researchers then compared the spatial patterns of the fairy circles with the current growth patterns of Euphorbia species, including E. damarana, E. gummifera and even E. gregaria. All of these roundish succulents contain a highly poisonous, latex-like sap.
The scientists propose that the Euphorbia species colonised the sandy soils when climatic conditions were more favourable. Research indicates that Namibia has experienced periods of significant temperature increase over the past few centuries. In the last three decades, temperatures have increased roughly three times more than the global mean. These high temperatures and increasingly arid conditions would have seen the Euphorbias competing for access to water and nutrients, particularly in soils with a low water-holding capacity. As a result, many would have died.
E. damarana and FCs in the background and the dead plant remains in the front on the Giribes Plain
However, the researchers theorise that while the plants may have died off, their legacies remained deep within the soils. As the dead plants decomposed, the sticky, toxic latex would have soaked into the soils and changed its chemical properties, making it more hydrophobic (repelling water). Other compounds capable of inhibiting plant growth and microbial activity would have entered the soil, trapped around soil particles as the latex solidified. This is an example of allelopathy – where organisms produce biochemicals that inhibit the growth of other organisms.
Their theory was supported by soil analysis which revealed that soil from the fairy circles and soil taken from beneath decomposing Euphorbia plants had very similar phytochemistry (chemicals produced by plants.)
The idea that dead Euphorbias may be behind the formation of the ‘fairy circles’ has been around since the 1970s, when botanists observed the co-occurrence of the plants and fairy circles. Researchers marked dead and decaying E. damarana plants in 1978, and these circles were not covered by grasses when rechecked in 2016. By integrating rainfall, altitude and landcover into a sophisticated suitability model, the researchers in this study were also able to predict where fairy circles would be expected to occur. This model largely overlapped with the distribution of the three Euphorbia species and also resulted in the discovery of more fairy circles in the South African section of the Kalahari Desert.
Site suitability prediction map for fairy circle distribution
However, this ‘fairy circle’ explanation has proved contentious, and there are still several scientific theories as to their origins. Sand termites (Psammotermes allocerus) were previously shown to be present in 100% of newly formed fairy circles, leading researchers to theorise that they were responsible. A recent research paper proposed that the circles are natural vegetation patterns that arose due to competition between different grass species.
For a hypothesis on the cause and maintenance of one of nature’s most mysterious phenomena to be accepted, it would have to explain all of the most important properties of the ‘fairy circles’ themselves. These include the mostly circular shape, their unusually high densities, their size and their changing diameter at different latitudes. The new study proposes an explanation of all of these characteristics, particularly given the almost circular shapes of the Euphorbia species.
If this hypothesis is correct, it also means that there is an astounding historical ‘footprint’ of hundreds of thousands of succulent Euphorbias, stretching from Angola in the north to South Africa in the south. It also explains the life-expectancy of the ‘fairy circles’ themselves. As rainfall gradually washes away the hardened latex from the soil particles, the toxins break down and allow for the natural plant succession process.

From our Editor-in-Chief
I would suggest that before you delve into the meat of our main stories, you pour a cup of tea/ coffee/ malt whisky, don a pair of headphones and push play on our video of the week (scroll down). It’s an inspirational tribute to Namibia by some tremendously talented Namibians and will kindle your wanderlust for wilderness.
Our first story below is not quite as inspirational as the video. The Okavango has lost all its rhino in the past, and it looks like the ignominy of another local extinction is on the cards if the government doesn’t acknowledge the upsurge in poaching.
For our second story below, you might want to pour your second tea/ coffee/ malt whisky before marvelling at the magic of Laikipia – a spectacularly beautiful collection of conservancies in central Kenya. It must be one of the most progressive attempts to incorporate the needs of human beings and wildlife in one protected space; a mosaic of commercial farms, rangelands and wildlife conservancies with huge biodiversity and endless choices for travellers of every bent.
In our third story below, some extremely dedicated souls from Elephants Alive have developed a coding system for identifying individual elephants based on their ages, tusks and ear features. The system has some hugely important applications for elephant monitoring and management.
Finally, the tenth week of Our Photographer of the Year carries a prize of 10 000 USD and a six-day safari to Khwai in Botswana. It’s an eclectic collection of Africa’s exuberant life from desert to ocean. Here’s how to enter. If you’ve captured an image that makes you smile or ponder, send it in – it might just do the same for everyone else!

SAFARI MECA
Laikipia in Kenya – a land of staggering beauty & biodiversity – a mosaic of wildlife conservancies, ranchlands & commercial farms
Our Photographer of the Year 2021 is open for submissions, with cash prizes of US$10,000 for the overall winner and the two runners-up. They and their partners will also join our CEO Simon Espley and his wife Lizz on the ultimate private safari in Botswana.
Laikipia – “It was not just the beauty and wildness of the landscape. It was not just the smells, intense of dust and elephant, of jasmine and moonflower, nor the incredible concert of birds singing with liquid voices in the golden afternoons. It was not just the profile of the hills and the short purple sunsets, nor the vivid colours of the hibiscus and of the sky and of the yellow grass, nor the emotions of a sudden rustle of leaves of a scared francolin while I was walking alone in the bush, nor the surprise of the leopard, still as a statue in the full moon.”
As Kuki Gallman so vividly describes in her iconic novel, I Dreamed of Africa, Laikipia is a land of staggering natural beauty and biodiversity, enriched by complex cultural strands of human history and influence. The plateau is a mosaic of wildlife conservancies, ranchlands, rangelands and commercial farms that bridge the gap between East Africa’s savannas to the south and the arid lands of the Horn of Africa to the north. Here, endangered species often roam alongside Boran cattle and camels across a conservation landscape unlike any other in Africa.
Game drives, conservation experiences, horse safaris and camel rides – just a few of the myriad wilderness activities on offer in Laikipia.
The basics
Laikipia (‘treeless plain’ in Maa) is one of Kenya’s 47 counties, covering an area of 9,500km2 (950,000 hectares) and part of the much broader Ewaso ecosystem. The Ewaso Ng’iro River flows north-east through the county, fed by tributaries flowing off Mount Kenya’s glaciers. For the most part, the entire region is open to wildlife and fences are limited to the wetter southern areas where farming is more prevalent, and human-wildlife conflict is a common occurence.
The landscape is dominated by ancient gneisses, which form rocky outcrops and hills, while the western lava sheets bear testament to the tumultuous history of the Great Rift Valley. The Aberdare Mountains run along Laikipia’s southwestern boundary, while Mount Kenya’s shadow looms large to the southeast. Most of the county lies at altitudes over 1,500m, so, despite lying across the Equator, the climate is relatively cool and temperate, becoming increasingly dry towards the central and northern regions.
Laikipia is wild, magical, whimsical
A different kind of wild space
Apart from Mukogodo and Rumuruti Forest Reserves, none of Laikipia’s various wildlife areas has formal protected status (that is, none of them is a game reserve or national park). Instead, the guardianship of the wilderness is based on the Kenyan conservancy model. Here, the lines between wild spaces and humanity are blurred. Many of the properties involved in wildlife conservation and tourism combine these efforts with raising livestock. Several group ranches are run by community-owned companies, many of which have dedicated their energies to conserving vast swathes of land.
Scattered throughout Laikipia are wildlife conservancies supported by a thriving tourism industry. The Laikipia Conservancies Association consists of 24 member conservancies which cover an area of 3,500km2 (350,000 hectares), including:
Ol Pejeta Conservancy
360km2 (36,000 hectares)
Ol Ari Nyiro (also known as Laikipia Nature Conservancy)
365km2 (36,500 hectares)
Naibunga (a group ranch composed of 9 ranches)
477km2 (47,700 hectares)
Loisaba Conservancy
226km2 (22,600 hectares)
Borana Conservancy (contiguous with Lewa Conservancy)
120km2 (12,000 hectares)
Il Ngwesi (a group ranch)
93km2 (9,300 hectares)
Lekuruki Conservancy
92km2 (9,200 hectares)
Ol Jogi Conservancy
240km2 (24,000 hectares)
Sosian Samburumburu
97km2 (9,700 hectares)
Ol-Lentille
162km2 (16,200 hectares)
The above list of operational conservancies is complemented by several unfenced private ranches, many of which offer their own intimate safari experience. Under the Laikipia Wildlife Foundation’s guidance, this extensive ecosystem is managed as a cohesive ecological entity. It is also open to the renowned Lewa Wildlife Conservancy to the east and attached to the Mount Kenya Forest and National Park to the southeast.
Laikipia’s precious wildlife treasures
The plateau’s gradual transition from intensive livestock farming to wildlife haven is a testament to the success of a progressive and inclusive conservation approach. Laikipia’s heterogeneous landscapes now offer some of the most magnificent wildlife viewing in Kenya, from the standard Big 5 experience to more unusual and elusive creatures. The county is home to the second-largest elephant population in Kenya, and many of these herds now migrate north to Samburu during the two rainy seasons. Naturally, big cat sightings are regular and always exciting, but equally enthralling are the opportunities to spot the sloping back of a striped hyena, the absurdly elongated neck of the peculiar gerenuk and the spear-tipped horns of the Beisa oryx. The exceptionally fortunate may even see one of the melanistic leopards recently confirmed to be lurking in some conservancies.
However, part of Laikipia’s real magic lies in its inordinate concentration of endangered species, particularly rhinos. Perhaps most famously, the Ol Pejeta Conservancy is home to the last two northern white rhinos in the world, vigilantly guarded day and night. Najin and her daughter Fatu were given to the Ol Pejeta Conservancy by the Dvůr Králové Zoo in Czechoslovakia in 2009. Najin’s father – Sudan – was the last surviving male northern white rhino until he died in 2018. At present, scientists are working towards creating embryos using sperm collected. Until this project succeeds, a visit to Laikipia offers the last opportunity to see the northern white rhino.
White rhinos aside, Laikipia is also home to nearly half of Kenya’s black rhinos. Many of the conservancies and ranches have dedicated rhino sanctuaries that have contributed immensely to rhino conservation in East Africa. The county is an important stronghold for the endangered Grévy’s zebra, reticulated giraffe (also known as the Somali giraffe), and Jackson’s hartebeest (regarded as a rare hybrid between the Lelwel and Coke’s hartebeest). African painted wolves (wild dogs) course across the vast woodlands and open plains, their propensity for covering large distances supported by the size of the ecosystem available to them. The Sweetwaters Chimpanzee Sanctuary in Ol Pejeta is also the only place in Kenya where visitors can see chimpanzees, as they do not occur naturally.

Variety and adventure – the Laikipia experience
Want to go on a safari to Laikipia? To find lodges, search for our ready-made packages or get in touch with our travel team to arrange your safari, scroll down to after this story.
Apart from its remarkable wildlife, the Laikipia experience can be defined by two quintessential principles: exclusivity and freedom. The private conservancies and ranches guarantee that visitors can immerse themselves in the wilderness, free from the almost crushing pressure of tourist numbers in the more renowned national parks and game reserves. This high quality, low-density approach to tourism has opened up unique experiences for visitors, such as accompanying ecological teams in the field to monitor endangered species, track lions or walk with baboon troops. Variety is the order of the day, and tailored adventures are the norm in Laikipia.
Free from the rules and restrictions of national parks, the lodges offer expertly guided walks, night drives and horse safaris. Intrepid visitors can opt to explore the landscape on a mountain bike or quad bike, rolling along paths inaccessible to the average vehicle and discovering hidden nooks and crannies. Those that prefer a more sedate pace can hop on the back of a camel and enjoy the scenery from a novel vantage point, accompanied by the gentle tinkle of camel train bells.
As a general rule, Laikipia does not stint on comfortable accommodation, though there are options available to suit tighter budgets. There are a number of either community-owned or community-operated lodges for conscience-driven travellers. However, it is important to note that access to the vast majority of the conservancies and ranches is restricted to guests, and only Ol Pejeta offers access to day visitors. Like the Maasai Mara, there are two rainy seasons: the ‘short’ rains in October/November and the ‘long’ rains lasting from March until June. Though rainfall levels are not as high as they are in the Mara, high rainfall may affect the activities and the wildlife viewing.
Camps for all tastes and pockets
A triumph of conservation
Though Laikipia offers various habitats and experiences for the discerning visitor, these are all underscored by a common theme – authenticity. In Laikipia, the fortunes of people and wildlife are inextricably linked. This is not to say that this process has been without its own challenges, and indeed, Laikipia has seen its fair share of conflict and heartache. However, the inclusive approach that values livelihoods and biodiversity has successfully used tourism to galvanize the creation of one of the largest wilderness areas in Kenya.
The concept of individually- or community-owned conservancies should be considered a Kenyan conservation success story. Tourists that visit these conservancies and ranches play an enormous role in ensuring the future of these protected wilderness areas and supporting a continuous revenue stream for the local communities. With over 65% of Kenyan wildlife existing outside of government-protected wilderness areas, it is easy to see why conservancies will be critical to conservation efforts in the future. The sprawling plateau of Laikipia, home to some of the most endangered species in Africa and steeped in complex history, is the perfect example of this process in action.
To the novice eye, most wild animals of the same species look mostly identical to each other unless marred by a prominent scar or perhaps sporting a different colour variation. However, closer observation reveals that each individual, whether leopard, lion, or elephant, possesses a set of identifying characteristics as unique as human fingerprints. For researchers monitoring these animals, being able to identify individuals is extremely useful for estimating populations and understanding demographics. However, the process is often time-consuming, labour intensive and subject to human bias. For 25 years, the team at Elephants Alive, spearheaded and led by Dr Michelle Henley (last author), have developed their own solution for elephant identification: a System of Elephant Ear-pattern Knowledge (SEEK).
Despite their size, monitoring elephants to estimate populations and demographics comes with its own set of complications. Traditional capture-mark-recapture techniques are expensive, dangerous, and impractical, large-scale aerial surveys are prohibitively expensive, and dung counts vary depending on vegetation type. This has necessitated the use of alternative techniques such as mark-resighting studies which in turn generally rely on photo-identification. The use of photographic records depends mostly on manual matching techniques and human memory, and while automated software models are in use, they still require further development.
The Elephants Alive team monitor elephants across the Associated Private Nature Reserves (APNR) on the western boundary of the Kruger National Park and have been conducting field research since 1996. The team began putting together their own simplified coding system at the start of the period which initially entailed creating detailed drawings of the ear features of individual elephants. The study was officially registered with South African National Parks (SANParks) in 2003 and has continued until the present day.
In 2012, the first comprehensive coding system was developed. The animal was grouped first according to sex and age and then incorporated into a feature and element system. The method was refined over time, to simplify the system and exclude observer bias for more complex shapes.
Today, each elephant assigned to the database has been given a unique code that corresponds to specific aspects of that individual. The first letter of the code will be either B (bull) or C (cow) and the following two numbers place the individual in an age bracket. Following that, the presence or absence of tusks is recorded. From there, features on the left ear have been assigned numbers depending on the position on the ear itself – with the most prominent tear listed first, followed by the most prominent hole, the second most prominent tear and the second most prominent hole (in this exact order). The right ear follows the same pattern. The coding system is completed with reference to the existence of extreme features (applied to ear tears or holes that cover more than 25% of the ear) and any other special features (a missing tail for example).
So, for example, B70T01E808_-403_X00S00 is a bull elephant, born between 1970 and 1979 (B70), with a tusk on his left side but not the right (T01). The most prominent tear and the second most prominent tear are both at the 8 position of his left ear (E808). On his right ear, the most prominent tear is on the 4 position, while the second most prominent tear sits on the 3 position (-403). Neither ear has any prominent holes. He does not have any extreme features nor any special elements (X00S00).
SEEK has been developed to follow the rules of the search function of both Microsoft Excel and Microsoft Word, allowing researchers to rapidly narrow down their search when presented with an image of an elephant they are trying to identify. If all recorded individuals are ruled out, the new elephant is added to the system. The additional Microsoft Office Wildcard function also allows for situations where not all characteristics are observable (if presented with only one side of the individual, for example).
The extensive development of SEEK is a truly extraordinary accomplishment, born of decades worth of research and practical experience. The evolution of this method has been shaped by the pragmatic realities of fieldwork while still allowing for identification accuracy, resulting in a system that can be applied by other such research programmes as well as an extensive historical database of elephant individuals in the Greater Kruger. From behavioural studies to understanding long-term population trends, individual identification is vital in the efforts to conserve one of the most iconic animals in Africa.
Botswana’s recent upsurge in rhino poaching is reaching a crisis point. More than 100 rhinos have been poached in under two years from a population of less than 400. Yet, the government remains resolute in its denial of a growing catastrophe.
Former Botswanan president Ian Khama recently announced on social media that over 120 rhinos have been poached in the past 18 months. The post said that poachers were ‘killing rhinos with or without horns,’ and that ‘after corona (virus) there will be none left for tourists to see.’
Botswana’s Department of Wildlife and National Parks (DWNP) has denied the accusation – saying Khama’s announcement is irresponsible and will negatively impact tourism. In a statement, the DWNP claims that wildlife-related crimes are down by 70 per cent since the COVID 19 period from March 2020.
But on the same day as DWNP’s statement release, Bhejane Trust, a Zimbabwean rhino conservation organisation, publicised the massacre of 12 more rhinos in the Okavango Delta in northern Botswana saying, ‘Urgent action is required by the Botswana authorities, and they should bring in expert advice and assistance immediately if any rhino(s) are to survive.’
Conservationists are concerned that Botswana’s rebuttal to its growing poaching crisis is encouraging rhino horn poachers to focus on the remaining rhino in the Okavango Delta area and could lead to an absence of safari tourists.
‘The current government already has a poor conservation record, and it seems to be following the same policy of denial it used with the elephant poaching over the last few years,’ says Ian Michler, conservationist and specialist wilderness guide. ‘Let’s be clear; the poaching syndicates have seen the weakness and have turned their attention on this country. Without a strong and effective response, Botswana runs the risk of seeing rhino disappear from its parks and reserves for the third time.’
After numbers crashed in the early nineties Botswana engaged in a rhino relocation project in 2001 which spanned over ten years, introducing viable populations of black and white rhinos back into the Okavango Delta.
In June last year, the Botswanan government began removing rhino horns and relocating rhinos away from the Delta in an attempt to reduce the risk of poaching. The official count for poached rhinos was 56 since 2018, marking it the worst onslaught since the country’s black rhino population was wiped out in 1992 and white rhinos dropped to below 30 individuals.
According to Dereck Joubert, who leads the Botswana non-profit Rhinos Without Borders, the relocation of rhinos away from the Delta was essential amid the coronavirus pandemic as poachers were using the absence of safari tourists during lockdown to their advantage. Asian rhino horn traders had also begun to tout rhino horn as a cure for the virus.
At that stage, nearly 50 poached rhinos had been recorded since late 2019.
In August 2020, the poaching crisis was still showing no sign of let-up and the government went back on its decision to reduce the military capability of the arms carried by its wildlife rangers. With 17 poachers shot dead in six months in gunfire exchange with the army, it was decided to re-arm anti-poaching rangers with military weapons.
Is this what it seems to be? An attempt by the government to minimise what is obviously a devastating onslaught on the last few remaining rhinos in Botswana; a repeat of their stance on elephants just two years ago?
In 2019, the newly elected President Mokgweetsi Masisi denied that elephant poaching was at a crisis point when aerial surveys revealed that almost 400 elephants had been poached between 2017 and 2018.
“The question remains: why is the Botswanan government not engaging the international community for help? Other countries are using NGOs and civil society to assist them with wildlife crime,” says Adrienne West of Political Animal Lobby. “Botswana cannot expect to tackle an issue of this magnitude alone.”

From our Editor-in-Chief
Our first story below is a scientific marvel born of potential catastrophe. What a sad state of affairs that it has come to this. Thank goodness for forward-thinking philanthropists prepared to throw money and action at a problem rather than conferences and committees. Hemmersbach Rhino Force has created a cryo-lab (basically an uber fancy freezer and Tupperware combo) for the harvesting of and storage of rhino gametes (swimmers and eggs) for the eventuality that these ancient pachyderms do not survive the poaching onslaught. The Cryovault is a remarkable, commendable and inspiring commitment.
Our second story below, from a wildlife veterinarian with decades of field experience provides strong evidence that fences were highly unlikely to have contributed to the Botswana elephant die-off in 2020 (as reported here). More than this perhaps, the story and its design point out the value of ground-truthing, common-sense and experience. It cautions that not even the peer-review process is infallible.

JUST IN CASE
Just in case: The rhino Cryovault holds repositories of rhino DNA, gametes, and tissues preserved indefinitely – in case we fail to save our rhino
Our Photographer of the Year 2021 is open for submissions, with cash prizes of US$10,000 for the overall winner and the two runners-up. They and their partners will also join our CEO Simon Espley and his wife Lizz on the ultimate private safari in Botswana.
The rhino Cryovault is a biobank that holds the largest genetic repositories of rhino DNA, gametes, and tissues in the world; frozen and preserved indefinitely. What does it mean to save a species? What happens if, in the absolute worst-case scenario, we fail? While Hemmersbach Rhino Force is doing everything in their power to make sure that does not happen, they do have one last ace – the rhino Cryovault.
In every cell of every organism, from the smallest bacterium to the hugest blue whale, four unique, organic molecules (nucleic acids) are arranged in their millions to form a genetic blueprint that dictates the organism’s – shape, potential size, dietary needs, reproductive proclivities, propensity for language, eye structure – the list is nearly endless. Within the DNA double helix, this code holds most of the secrets to the diversity of life as we know it. Every time a rhino is poached, an entirely unique genetic fingerprint is lost.

What is genetic diversity?
The term “biodiversity” has become very popular since first introduced in scientific publications of the 70s. By now, most people understand that the foundation of conservation rests on protecting biodiversity. Biodiversity refers to the variety of species in an ecosystem, their ecological complexes and their interactions within an ecosystem. The third level of biodiversity is a measure of the variety of genetic characteristics within a species – genetic diversity.
It should be relatively self-explanatory why genetic diversity is of fundamental importance to the survival of a species. In the long-term, genetic diversity underpins one of the cornerstones of evolutionary theory. Genetic differences translate to certain traits that allow some organisms to breed more successfully than others – survival of the fittest. Greater genetic diversity within a species enables adaptation to changing environments (think climate change) and confers greater disease resistance to the species as a whole.
Conversely, as individual numbers of a species decrease, inbreeding will result in a loss of genetic diversity, which will decrease a species’ robustness in the face of new challenges (parasites, climatic changes etc). Inbreeding can also cause ‘inbreeding depression’, which is the reduced biological fitness of a population. This can lead to severe genetic defects, reduced fertility and even infertility. In essence, when humans decimate biology (animals, plants, mushrooms etc), we are not only destroying individuals and their potential genetic legacies, but we are also reducing the species’ capacity to recover and overcome adversity.
The Rhino Force team at work
Hemmersbach Rhino Force
Enter Hemmersbach Rhino Force, a direct action conservation organisation dedicated to safeguarding Africa’s remaining rhinos. Their anti-poaching services are provided free-of-charge and utilise a combination of innovative tactics, cutting-edge technology and old-fashioned boots-on-the-ground to tackle wildlife crime in Southern Africa. Rhino Force is operational in the Greater Kruger region (where some 50% of poaching events in Africa occur). They work with local authorities, private entities and anti-poaching operations on everything from surveillance and intelligence to proactive prevention and forensic work. In addition, their Zambezi Black Rhino Project in Zimbabwe is geared towards restoring a wild haven for the reintroduction of black rhinos, once abundant before poaching devastated their numbers.
Rhino Force’s holistic approach to protecting rhinos includes extensive work with local communities, promoting education and employment and tackling anti-poaching through anti-poverty strategies. Improving living conditions, restoring and equipping schools, litter removal, and supporting community engagement are just some of the initiatives that the Rhino Force has thrown their weight behind.
However, the sheer severity of the rhino poaching crisis prompted the creation of the Hemmersbach Rhino Force Cryovault in 2018, a biobank of vital biomaterial including DNA and viable sperm. As unsettling as it is, we must face the reality that we may not be able to stem the tide of poaching. This proactive approach is intended to create a genetic backup before it is too late.
The Cryovault field laboratory
The Cryovault and Veterinary Unit
The Cryovault team consists of Dr Imke Lüders, a specialist veterinarian from Germany and Dr Janine Meuffels, a veterinarian from South Africa. The team members all have long-standing backgrounds in animal reproduction and wildlife medicine. They are, at present, the most experienced team in Africa at executing large-scale gamete conservation projects. Together, they have successfully collaborated in collecting semen from elephants, giraffes, and rhinos, from both live (intra-vitam) and deceased (post mortem) animals in wild and captive situations.
As with any other Rhino Force projects, the Cyrovault is not a commercial operation. Instead, it provides specialist veterinary wildlife reproduction and biotechnology support services to other scientists, veterinarians and their clients. The laboratories are equipped with the resources necessary to evaluate gametes’ viability and store tissues, gametes, and DNA indefinitely through cryo-preservation.

The ART of reproduction
Assisted reproduction technologies (ART) including artificial insemination, in-vitro fertilisation and embryo transfer are techniques that have been used successfully for years, particularly in the agricultural industry with livestock. There is a perception that because these techniques have been so effectively applied in both humans and livestock, it should be simple to transfer them to wild species. However, this is far from the case. Every species has evolved a unique anatomy and reproductive physiology. Successful ART requires extensive research and the development of species-specific protocols. Unravelling secrets of ART for the African rhino species is the calling of the Cryovault team.
Theriogenology – which concerns the study of veterinary reproductive medicine and surgery – is a field subject to continual refinement. Conservation-minded reproductive specialists are continually searching for ways in which these techniques can be used to balance the odds for threatened species. Viable semen has been collected and cryopreserved, leading to successful artificial insemination (using both fresh and frozen semen) of elephants, giraffes, and southern white and Indian rhinos. However, most advancements in wild species have been made in captive settings where scientists have unrestricted access to the animals.
The Cryovault team continues to offer tremendous contributions to this knowledge base, and in 2020, they collected, processed and cryopreserved free-ranging (wild) black rhino sperm samples – a world first. They have teamed up with Eastern Cape Parks and Tourism Agency (ECPTA) for a three year project to collect and store samples from as many black rhino individuals as possible.
Where rhinos are concerned, the Cryovault team’s approach to gamete collection is largely opportunistic currently. When a live bull rhino is anaesthetised for a routine process such as a dehorning or ear notching, the team applies a low-voltage stimulation to the prostate gland in a process known as electroejaculation. In the case of poached, hunted, or euthanised animals, the testes are harvested in their entirety. Once the samples return to the lab, the viability of the sperm is tested and, if shown to be suitable, it is transferred to sperm straws and frozen using liquid nitrogen. It is even possible to separate the sperm cells according to whether they carry an X or Y chromosome, thus controlling the sex of potential offspring.
The process of ovum (egg) collection from a live female rhino is known as an ovum pick up. This is a highly specialised technique and requires the regulation of several physiological factors. The team can also harvest oocytes from deceased animals, but with only a six-hour window in which to do so. This is logistically complicated – with a low success rate.

Managed wildlife breeding – a conservation tool
What does this science mean for the future of our rhinos? The reality is that there are few self-sustaining wild rhino populations left throughout the world. In South Africa, home to most of Africa’s rhino, roughly a third are privately owned. Most of these populations are already intensively managed. Suppose the captive growth rate, and the poaching rate continue along the same trajectory. This eventuality could quickly shift the proportion of privately-owned rhino to 50%. The onus will be on private owners to protect the remaining rhinos. Intensive breeding management programmes are an inevitable part of a survival plan for a species approaching the brink. Accepting that rhinos are on that list must happen sooner rather than later.
One of the primary objectives is for the Cryovault facility to be the largest of its kind for African rhino genetics. This massive archive will contribute enormously to DNA population genetics research and act as a reference database for the species. Most importantly, it can be applied to both current and future rhino breeding. Expanding our collective knowledge of rhino reproductive physiology, gametes’ parameters and developing protocols for successful, repeatable methods of assisted reproduction that can be applied to rhinos, is of paramount (and urgent) importance.
Back from the brink (again?)
In the past, the call for reproductive specialists to save a species on the brink has generally come far too late, when just a few individuals of the species remain. Developing appropriate techniques and protocols at this stage is impossible, and the rhino Cryovault team is entirely focussed on ensuring that this time, the approach is a proactive one.
While it may be impossible to freeze time, the Cryovault offers the next best thing – a way to ensure that, in the worst-case scenario, we can preserve some of the genetic legacies of our rhinos before they are lost forever.

We asked Botswana-based wildlife veterinarian Erik Verrynne to shed light on the issue of whether fences prevent elephant migrations and restrict their movements in northern Botswana. This clarification is required after this research paper ‘The 2020 elephant die-off in Botswana’ by van Aarde et al, on 11 January 2021 [1] and our summary . In it, the authors claim that fences are an underlying cause for the elephant mortalities in NG11/12 (Botswana) in 2020.

Wildlife vet Erik Verrynne:
Introduction
The scientists used movement data from 13 collared elephants in the Seronga area between 2003 and 2006 to prove that the elephant population is unable to cross barriers formed by surrounding fences, deep-water channels of the Okavango River and human activity (harassment).
The study concluded that the ‘boxed-in’ effect created by the boundaries prevent elephants from migrating to other areas during times of food pressure, or from regularly reaching the fresh water of the Okavango River.
The elephants are therefore forced to drink the stagnant water of the waterholes which increases stress and the risk of drinking pathogens such as cyanobacteria toxins or infectious agents.
The underlying stress in a growing, boxed-in elephant population is a potential cause of increased disease susceptibility and contributed to the die-offs.
They postulate that the ‘boxed- in’ effect would have enhanced the fast spread of the agent within the population but prevented the spread to other populations outside the Seronga area.
The article places the die-offs and the underlying ecological drivers within the context of the resistance hypothesis and the metapopulation theory by proposing the realignment of veterinary fences to promote dispersal.
Botswana relies on the dispersal of elephants into the Kavango-Zambezi Transfrontier Conservation Area (KAZA) to reduce its large elephant population. At the same time, it is trying to prevent cattle contact with potentially disease-spreading cloven-hoofed wildlife species in order to protect beef export markets. More than 20% of the elephant population in Botswana shares land with subsistence beef and crop farmers where fences are used to protect cattle against disease. The Seronga area, with 15 000 elephants, is an area where both elephant crop damage and disease restrictions have socio-economic implications for the communities.
The potential of commodity-based trade is currently being investigated in Seronga as an alternative to veterinary fencing. Additionally, the Government of Botswana (GoB) has been looking into designs of species-specific targeting fences, while NGOs are working hard on programmes such as Ecoexist to promote coexistence between communities and elephants.
Despite all efforts, the dispersal of elephants away from Botswana as a long-term solution remains a challenge. Figures released by GoB indicate that only about 20% of the large KAZA elephant population is dispersing freely between countries, mainly between Botswana and Zimbabwe. The challenges are further illustrated by dispersals deeper into Botswana during the drought of 2017/2018 rather than into neighbouring range states.

What is causing the resistance to dispersal and do fences and channels play a role?
The reasons for the low dispersal levels in many areas seem to vary. Proposed solutions follow a large-scale approach based on general assumptions, often ignoring local factors.
The article suggesting that fences facilitate elephant deaths illustrates the challenges we face. Remote sensing data is used to postulate drivers and causes, and to offer solutions, while local knowledge or fieldwork critical to verify the collected data is ignored.
The fences around the area are the double veterinary border fence between Bwabwata NP in Namibia and the Seronga area of NG11/NG13 in Botswana, and the northern buffalo fence. The latter fence was erected in 1995/96 to prevent the spread of contagious bovine pleuropneumonia (CBPP) that came across from Namibia. CBPP was declared under control in 1998 only after the mass slaughter of 320,000 cattle.
Albertson (1998) reported how the northern buffalo fence cut off migratory patterns of zebra and elephant, causing the death of migratory species and even an elephant cow and calf. The original fences consisted of sturdy 1,2 m – 1.4m high wooden posts and intermediate wooden droppers connected with strands of steel wire and a single strong steel cable to strengthen it against elephant damage. At the time the fences were regularly maintained to prevent the crossing of any cattle or buffalo. After CBPP containment and the subsequent removal of the Setata fence in 2003, seasonal migrations of wildlife across the removed fence resumed. Therefore, in some cases, fences can present effective barriers to elephants.
The authors of the article stated that the fences in question are still being maintained and therefore present impermeable barriers to elephants wanting to disperse. A quick visit would have immediately shown that this is not the case. Even the current condition of the international boundary fence is not capable of blocking the movement of cattle or buffalo in certain places although in general, it appears much sturdier than the northern buffalo fence.
Over the last few years, I have visited different parts of the fences in question with the exception of the western section of the international boundary near Mohembo, and the section of the northern buffalo fence from the Selinda gate to the north through NG13.
The sections of all the fences I visited had gaps where the fence was either on its side, or most steel wire strands and wooden intermediate droppers were missing. In many cases, the connecting steel cable was on the ground, covered by vegetation. Elephants and antelope were crossing the northern buffalo fence at will while I saw tracks of a few solitary elephants crossing the double vet boundary with Bwabwata NP.
The presence of active photographic tourism lodges and sporadic patrols by the Botswana Defence Force may account for the fact that there is reportedly little poaching in NG12. Neither the fences nor the small amount of human activity on the southern boundary are likely to restrict the movement of elephants out of the Seronga area.
Realignment of the current veterinary fences, even removal of the international boundary fence would not, in my opinion, have a significant impact on, or resolve future cases of disease outbreaks in elephants in the area as claimed by the authors.
Elephant reluctance to move across the deep channel at Seronga remains a mystery. Elephants along the Chobe River cross deep water at will. We regularly see bulls and family herds crossing over onto the sinuous islands, wading chest-deep across the deep channels around Kadizora and Xanaxara. The reluctance to cross water may simply be driven by individual behavioural preferences.

If it is not the fences, why are the elephants not moving?
Verifying the movement data to see if the elephants are indeed not moving out of the Seronga area should be the first reaction. Unfortunately, it is difficult to see if the presented data support the statement of a ‘boxed in’- effect.
The authors present data of only 13 elephants within the Seronga and adjacent areas between 2003 and 2010 while reference to 25 more collared elephants was not supported with data and therefore could not be considered. Therefore, the lack of access to raw and other referred movement data, and the historical nature of the data makes it difficult to place the claims in perspective.
However, other collaring data and anecdotal evidence and observations confirm the lack of mass dispersals of elephants in and out of the Seronga area. Local seasonal movements between food and water sources inside the Seronga area by a large part of the population and very localised seasonal movement of small numbers between NG12 and NG16 are regularly-reported occurrences.
Dispersal does not happen spontaneously. It must be driven by a catalyst usually generated by a change in resources, environmental conditions, or threats strong enough to elicit a group response and overcome memories of any previous hindrance. The response must have the potential to correct or improve the situation both to the individual and the population.
Thirst is a major driver for elephant migrations or dispersals. The restricted access to water is acknowledged in the article in supporting the need to disperse. However, the authors failed to consider the opposite situation where sufficient key resources and safety may nullify the sustained pressure to disperse. In short, the elephants may not want to move because the food, water and shelter is enough for most of the year, while the conflict and harassment by people is short-lived and can be mitigated without the need to migrate.

How sustainable are the key resources?
Key resources in the Seronga area are provided by both the seasonal floodplains, long sinuous islands, and the woodlands.
NG12 is the area to the south of the line of fields and villages and is covered by the seasonal floodplains which vary in width from 3 to 10 km. Across the floodplains NG 12 transitions into a series of long sinuous islands. It ends in the sandy Kalahari apple leaf islands and shrub mopanes towards Vumbra Plains (NG22) in the south, the reedbeds of the deeper channels of NG23 to the southwest and mopane belts to the east into NG16. Many circular islands on the seasonal floodplains accommodate a variety of large riverine forest trees, with jackal berries (Diospyros mespiliformis) and water berries (Syzygium cordatum) providing much sought-after fruit in late winter and early spring. The browse potential for elephants on the circular islands is relatively low and during the dry season, some herds cross over the seasonal floodplains onto the long sinuous islands in search of food.
The most important resource on the seasonal floodplains is therefore fresh water during the dry season of May to October, and during droughts. Water in the woodlands is only available at the latest up to July. The river starts flooding the floodplains at Gunistoga in late March or early April, retracting in June but water in large pans and deep channels remains, sustaining the elephants, wildlife, and cattle until thunderstorms provide water in the north again. While the Okavango River is flowing, the channels provide water, and the floodplains remain the most important sustainability factor during drought. The woodlands to the north in NG11/ NG13 and long sinuous islands to the south provide the other key resources.
The major impact zone is the line of fields and villages along the road and banks of the floodplains where 16 000 people live in 13 villages and numerous settlements. Fields for subsistence crop farming stretch up to 15km, but on average about 6km from the villages towards the woodlands in the north.
Once past the 10 to 15km impact zone, the woodland vegetation transitions into a mosaic of deciduous broad-leaved trees in the deep Kalahari sands, alternating with more claylike soils, where a combination of shrub and cathedral mopane dominates. The woodland vegetation is lush and dense during the wet season but most of the trees lose their leaves at the height of the dry season (July, August and September). As result, a part of the elephant population crosses the floodplains to the sinuous islands where they feed on a variety of trees and mopane shrubs.
The largest part of the elephant population switches back to remain in the woodlands almost immediately when the first thunderstorms fill the pans. Only a small part of the population remains close to the impact zone, drinking from the water on the floodplains. They remain invisible most of the time, their tracks crossing the main road at night as they move between the nearby browse and the waterholes on the floodplains past the fields and villages.
Numerous waterholes or pans formed in the clay soils of the mopane woodland fill during the rainy season between November and April and provide water to the wildlife and livestock that move north into the woodlands for the wet season.
It is some of these waterholes that were implicated as sources of the cyanobacteria toxicity in the mortalities amidst much speculation. However, indications are that mortalities had already started in March when it was still raining, while some carcasses were found in flowing water on the floodplains. Both conditions are less favourable for algal blooms. In my opinion, the true cause of mortalities remains unknown and open to speculation.
Overlapping and sustained utilisation by elephants, other wildlife, people, and livestock, have created the high-impact utilisation zone with many trees destroyed and mopane reduced to shrubs. This zone represents high risk and low resource use to the elephants in the dry season because they are forced to cross the zone daily between available resources. Risk is avoided by moving mainly at night and at speed, using elephant highways and the 13 corridors demarcated by Ecoexist as known routes past the field and village lines. By this time, crop harvesting has fortunately finished. By mid-May, most fields are empty. (Crop raiding happens from January to mainly April and seems to involve a small part of the population that remains close to the impact zone.)

Why are they not dispersing during the drought and will elephants eventually move?
Elephants are hindgut fermenters that digest cellulose in their massive colons. This evolutionary adaptation does not need quality feed, but quantity – something the high-biomass mopane and apple leaf areas can provide in abundance. The adaptation also allows them to utilise twigs, branches, and bark in the absence of leaves during the dry season or drought. They can push tree resources beyond normal resilience thresholds to levels of advanced deterioration before it negatively affects the nutritional intake values, provided the elephants have access to enough water. The thermoregulatory needs of such large animals when ambient temperatures are high, also necessitate water. Elephants are able to travel more than 20 km a day between food and water, an ability that mitigates their water dependency during droughts.
Drought, impact from an increasing elephant population, and an increase in human utilisation of resources around village lines in the impact zone, are causing deterioration which is gradually widening the impact zone into the woodlands, onto the floodplains and even onto the fertile long sinuous islands. Eventually, it may reach a threshold where the abilities of the elephants to negotiate the distances to water, and the increased conflict-related harassment will be sufficient to drive dispersal or migration. Only then is it likely that they will consider moving closer to the water resources of the Linyanti, Kwando or Zambezi Rivers.
The dispersal thresholds are unknown, as the resources appear to be more resilient than the tolerance of the villagers. The ensuing conflict may burst the dam wall long before the resources give in. Managing co-existence is a challenge for Botswana
For now, the elephants seem to be staying. Not because of fences or deep-water channels, but simply because the available resources suit them. Alternative key resources may not be close enough, and they may have adapted local strategies to mitigate droughts and human conflict risks. Drivers or memories of good places far away may not be strong enough to justify dispersal despite disease or harassment. Memories of some of the old barriers is still strong enough to remove the immediate need to move to other unknown areas.
The behaviour of the Seronga area elephants raises some questions about our theories on the metapopulations and dispersal within KAZA. Maybe it is time to acknowledge that elephants exert a choice based on the available resources or even memories of what appear to be boundaries. Our expected thresholds on resource utilisation may be wrong and elephant migration preferences may be more localised. Promoting dispersal across KAZA may require stronger drivers than simply removing fences. Elephants may consider our proverbial grass as not always greener on the other side of our fences.

Here’s something for us all to think about: One is made of compressed carbon and the other of compressed keratin. And yet, both are highly valued as status symbols because manipulative marketing campaigns have duped humans into believing the fairytale. Both are extracted at massive ecological cost amidst a plague of bloodshed and criminal activity where a few individuals scoop the financial windfall, and others pay the price. Think about that next time you check out that diamond or criticise someone who does the same with rhino horn—mea culpa.
The on-off journey continues! Distressing news is that the green light has now been given for large-scale open-pit mining in Zambia’s Lower Zambezi National Park. This saga has so many twists and turns it’s tough to keep up! Don’t get me started.

From our Editor-in-Chief
The saga of the Namibian elephant auction continues. The auction is complete but it is unclear who has bought the elephants, how many were sold or where they will go. There has been widespread anger and criticism from various armchairs, keyboards, conservation NGOs and journalists. The Namibian Ministry of Environment Foresty and Tourism, meanwhile, has taken exception to the auction being portrayed as a corruption-driven scam and painted many objections as the hysterical rantings of people utterly bereft of on-the-ground realities. In our first story below, Gail Thomson, an independent Namibian environmentalist, reviews the reasons for the sale.
After that rather heavy yet necessary read, our second story below will have you daydreaming of being suspended in the verdant forest canopy of the Albertine Rift; the ancient cacophony of screeching primates and avian choirs lulling you to peace. Nyungwe National Park in Rwanda is home to bird megaticks, breathtaking vistas, waterfalls, trails and rare primates. There are options for all budgets so sit back and immerse yourself in the mystical magic of the forest.
Finally, the eighth week of celebrating the beauty of Africa through our Photographer of the Year, which carries a prize of 10 000 USD and a six-day safari to Khwai in Botswana. Enter here. Remember you don’t need a boat-load of obscenely expensive kit to take a good pic. You might even be lucky with your phone! Your image needs to tell a story and evoke an emotion.
Our Photographer of the Year 2021 is open for submissions, with cash prizes of US$10,000 for the overall winner and the two runners-up. They and their partners will also join our CEO Simon Espley and his wife Lizz on the ultimate private safari in Botswana.

I find myself confused and at odds with what I understood about the possible origins of Covid-19 after reading 
African safari….the idea conjures all sorts of images: Denys and Karen flying over the Mara in a Gypsy Moth; a lion roaring atop a rock as he surveys his singing, dancing prey at dawn; a gargantuan tusker framed by the snow-topped peaks of Mount Kilimanjaro. It is to the last of these iconic imaginings that we turn our attention this week. In our first story below, you can stimulate your post-Covid wanderlust with the wonders of Amboseli National Park (and the greater Amboseli region).
