Update on the disease killing our rabbits:

Rabbit Haemorrhagic Disease Virus

Johan du Plessis, EWT’s Drylands Conservation Programme Manager

In October 2022, a report came through to the EWT of a dead Scrub Hare in the Sutherland-Middelpos area in the Northern Cape. It was not an unusual occurrence, but it was just the first of many cases of hare and rabbit (lagomorph) deaths rapidly spreading as far as Springbok and Fraserburg in the Northern Cape and the Montagu area in the Western Cape. It was clear that something was infecting and killing rabbits much faster than normal.

We knew something very worrying was out there and feared for our indigenous lagomorph species. After testing affected carcasses at the Onderstepoort Veterinary Research Laboratory, the Department of Agriculture, Land Reform and Rural Development issued a media statement on 17 November 2022 announcing what many had begun to suspect – the culprit behind the widespread mortalities of wild hares and domestic rabbits was confirmed as Rabbit Haemorrhagic Disease Virus (RHDV) – strain RHDV2. There have been more recent reports of wild hares dying in the Merweville and Beaufort West regions and domestic rabbits in Cape Town and surrounds. The presence of RHDV in South Africa, particularly in these areas, is of great concern as our indigenous Red Rock Rabbit, the Critically Endangered Riverine Rabbit, and other indigenous hare species are all susceptible to the virus, and they are far less prolific than domestic rabbits, and we cannot afford to lose too many or the populations will be under threat.

The virus originated in China in 1984 and has since spread to many countries. This virus is highly contagious but only affects lagomorphs (rabbits and hares). It spreads very easily, normally through direct contact between animals, but the virus is most likely also carried by flies and scavengers feeding on carcasses, and on clothes, shoes, and car tyres. RHDV is a controlled animal disease. We recommend contacting your nearest state veterinarian to take samples if you encounter unnaturally large numbers of dead rabbits/hares on your property. The unnecessary transport and touching of infected carcasses should be avoided as far as possible.

During the past few months, the EWT has tracked and mapped all known hare and rabbit deaths. While there have been many reports of dead hares and domestic rabbits, there have fortunately only been a few Red Rock Rabbit mortalities and no reported deaths of Riverine Rabbits. We continue to work closely with the department to record and map all reports and are pleased to note that the number of deaths reported has declined since December 2022.

We urge farmers to report any wild hare and rabbit deaths to ewt@ewt.org.za and include your name, farm name, cell number, and GPS location of the incidents (if possible). Please also contact your local state vet and request that necropsies be done and the specimens sent to Onderstepoort. Farmers with Riverine Rabbits on their farms are requested to monitor the riparian areas and immediately report any Riverine Rabbit deaths to the EWT.

Our Drylands Conservation Programme is also working closely with provincial and state veterinary departments to develop best practice guidelines on managing dead rabbits and hares on your property. These will be released as soon as possible. Until then, please get in touch with the local state vet for assistance with wild hares/rabbits, which can be identified with the help of the attached poster.

Andre Botha, EWT’s Vultures for Africa Programme Manager

Conservationists from the EWT and its partners, the Chuilexi Conservancy, Niassa Carnivore Project, and WCS/ANAC from the Niassa Special Reserve (NSR) in Mozambique were recently astounded when one of their tracked birds started exploring the wider Mozambique landscape.

On 10 June 2022, an immature female Bateleur Eagle (Terathopius ecaudatus) was trapped and fitted with a GSM tracking unit as part of the work to establish a tracking sample of 23 vultures and other scavenging birds in this beautiful northern Mozambique landscape. Contrary to expectations that this bird would remain within the confines of the NSR, she almost immediately started venturing east from Niassa to the coast, where she spent a significant amount of time in the Quirimbas National Park northeast of the city of Pemba, and even roamed further north into southern Tanzania at times, often returning to Niassa.

In late January/early February 2023, this pattern of movement significantly altered when the bird started heading southwest, briefly skirting the Malawian border before travelling further south and passing east of Gorongosa National Park, across the Pungwe and Save rivers to where her tracking unit shows she is currently spending time in the Banhine National Park, approximately 1,200 km south of Niassa. This scale of movement is usually associated with migratory species or vultures and is rather unexpected in this less adventurous species, although adults are known to cover considerable distances within their foraging range daily.

This scale of movement emphasises how little we know about the movements of this Endangered species and the need for a more detailed study of its movement biology. As with vultures, a better understanding of Bateleur movements will enable us to identify key staging, foraging and other sites where appropriate conservation action can be focused. We will be keeping a close eye on this bold Bateleur – who knows where she may wander next?

Cath Vise, Soutpansberg Protected Area Manager

Chris Joubert, our Medike Nature Reserve & Eco-Tourism Manager, will sadly be leaving Medike and the EWT at the end of March 2023, and I’d like to take this opportunity to express my sincere appreciation to him for all his efforts in the Soutpansberg.

Chris – thank you so much for all your hard work over the past two years. For the endless hours fixing old infrastructure and questionable plumbing, wrangling multiple contractors to get upgrades done, and keeping Medike and our rangers safe and sound. Thank you, especially for all your efforts in opening up Thomas Wilson Pass – the many long hours in the heat of the bush, enduring all the Mopani Bee bites, early mornings, late evenings, and a lot of excavator issues and breakdowns. The road is spectacular and something you can be extremely proud of. Thank you for taking so much care while manoeuvring an excavator through such a sensitive environment. It is very rough terrain and not easy for building a road, and I am so impressed that you and Frank (the excavator driver) managed to get through some of the areas you did and that we can now drive from Medike West to East, on the most spectacular 4×4 mountain pass. I am sure all who drive it will love and be grateful for it!

Thank you for being the friendly, welcoming face of Medike, for guiding and contributing to the development of our now Green Flag accredited Old Salt Trail, for managing marathon support stations and ensuring trails were good to go, for looking after visiting students, and especially for the role you play in our mountain conservation community.

I’d like to wish you all the best and good luck in your new opportunities. Enjoy the dry, northern side of our mountain and remember that you are always welcome at Medike and will always be part of our extended EWT Soutpansberg family.

Suzette Britz

Emily Taylor, EWT Communications Manager

Suzette joined the EWT in October 2021 during a whirlwind time for the Communications and Marketing Department with lots of projects that needed design assistance and us a short way into our biggest project of the year – the annual Integrated Report. She hit the ground running – calm, collected, and extremely capable – she took it in her stride and, despite the pressure, produced incredible work time and again. In 2022, Suzette was tasked with a mammoth project – revamping our digital platforms and website. For those of you who saw our previous site, I’m sure you will agree that the new site is streets ahead, both to look at and to use. Few people realise the work that goes on behind the scenes in a project like that, and despite performing all her day-to-day graphic work, she delivered a flawless product in record time.

As a fairly new manager, it was a great relief to have her working beside me – taking on any task I threw at her capably and calmly. I never had to worry that she wouldn’t deliver or impress. We have received nothing but praise for our digital and print materials produced during Suzette’s time with the EWT, and she leaves a truly remarkable legacy with designs that will be used and loved for years to come.

Thank you, Suzette, for your hard work and commitment, your calm in sometimes turbulent waters, and your support and friendship. The EWT is honoured and grateful for all you have achieved in your time with us, and we wish you all the best for your bright future. You will always be part of the EWT family.

Sean Kelly

Dr Andrew Taylor and Shadi Henrico, EWT Wildlife in Trade Programme

Sean Joined our EWT canine unit in September 2021 to work with us on our IUCN SOS project to deploy conservation dogs to reserves with important populations of threatened species. Sean brought many years of dog handling experience with him and strengthened our team considerably. He is very energetic and is constantly on the go, and even when not working with the dogs, he makes sure everything involving the infrastructure needed for the dogs is functioning. As one would hope for in a good dog handler, Sean always put the dogs first and even took on the responsibility of housing two of our working dogs at home when we were short of kennel space. We are very thankful to Sean for his hard work and commitment to our dog projects and wish him all the very best in his future endeavours.

A dead Endangered Kafue Lechwe Antelope (Kobus leche kafuensis)

Saziso Moyo, EWT-ICF Partnership African Crane Conservation Programme

The Endangered Kafue Lechwe antelope (Kobus leche kafuensis) is the predominant antelope species of the Kafue basin. These lechwes are semi-aquatic, medium-sized antelopes that live in large groups close to water bodies or marshes. The antelope engage in competitive displays and courtship rituals, known as lekking, to entice visiting females who are surveying prospective partners with whom to mate. The lechwe population in the Kafue basin has steadily declined from an estimated 80,000 in 1975 to about 23,000 in 2018, leading to its inclusion on the IUCN Red List of Threatened Species. For this reason, the International Crane Foundation/Endangered Wildlife Trust (ICF/EWT) Partnership has, in addition to the crane species we focus on, included the Kafue Lechwe on the list of important species to monitor and conserve. To achieve this, it has become increasingly important to investigate all potential factors contributing to the decline of the Kafue Lechwe population.

During the dry season in 2022, the Kafue Lechwe were dying daily, sometimes as many as 10-20, with the females and young being among the most affected. The ICF/EWT research team and field patrol officers detected this during mandatory monitoring activities.

A team of veterinarians from the University of Zambia (UNZA), the Department of National Parks and Wildlife (DNPW), and the Central Veterinary Research Institute (CVRI) was put together by ICF/EWT to investigate the cause of the alarming mortalities. The DNPW permitted the team to hunt down three lechwes to collect substantial samples of the internal organs. The reports revealed that the lechwes had various health issues, including bacteria and endo- and ectoparasites. The vet team argued that the bacteria and other health issues uncovered were not enough to kill the lechwe, but a combination of the disease load and poor nutritional value of their remaining food source could be acting together to cause the high number of deaths observed.

The report specifically indicates the presence of bacteria such as E. coli, Moraxella spp, and Klebsiella spp. The E. coli is because of the open defecation practised in the fishing villages. The villages have open pit toilets released directly into the water during flood season, presenting a significant public health issue for the people living in fishing villages and for the lechwe that drink from these water holes. Other causes of high mortality rates in the lechwe are human encroachment and the competition for food with the cattle that now number around 80,000 on the Kafue Flats.

The next step will involve presenting these results to relevant stakeholders and authorities for further action. Solutions may include developing a sanitation programme for the villages and a comprehensive management plan for the Kafue Flats for the well-being of people and wildlife.

Additionally, this calls for a deliberate, aggressive monitoring programme of the Kafue Lechwe involving the institutions mentioned above. Monitoring will help us to understand the stress factors and the potential mitigation measures to implement to ensure a thriving wetland for ALL.

Decoding alphabet soup reveals a historical achievement in global conservation

Decoding alphabet soup reveals a historical achievement in global conservation

 
Dr Gabi Teren, EWT National Biodiversity and Business Network, Programme Manager

 

On December 19, The UN CBD COP-15 adopted the Post-2020 GBF with the key 30×30 target for NBSAPs.

Scientists love talking in acronyms or alphabet soup. Let me unpack this for you by describing a recent momentous conservation achievement. The UN CBD – The United Nations Convention on Biological Diversity (CBD), ratified by 196 nations in 1992, encourages actions that will lead to a sustainable future, including:

“the conservation of biological diversity, the sustainable use of its components and the fair and equitable sharing of the benefits arising out of the utilisation of genetic resources”

COP15 Business and Biodiversity Forum plenary session

Every few years, the 196 countries party to the convention (including South Africa, but notably not the USA) meet at a Conference of the Parties (COP). The COP27, the 27th meeting of the UN Framework Convention on Climate Change (UNFCCC) parties, was held in November in Sharm el-Shaikh. COP15 was subsequently held in Montreal, Canada. You may be thinking someone really can’t do arithmetic, but there are different conventions that focus on different aspects of environmental action. The former COP (27) was the annual UN Climate Change Conference that advances global climate talks, mobilises action, and provides opportunities to look at the impacts of climate change and potential innovation and solutions in Africa.

COP15, on the other hand, united parties to the Convention on Biological Diversity to review and sign into the Post-2020 Kunming-Montreal Global Biodiversity Framework (GBF). This was essentially equivalent to the famed Paris Agreement signed by the UNFCCC, which is THE international agreement to try and keep the rise in mean global temperature below 1.5 °C to help countries adapt to the disastrous effects of climate change.

The GBF is trying to help the world adapt to the disastrous effects of extinction and biodiversity loss.

“ An average of around 25 per cent of species in assessed animal and plant groups are threatened, suggesting that around 1 million species already face extinction, many within decades unless action is taken to reduce the intensity of drivers of biodiversity loss. Without such action, there will be a further acceleration in the global rate of species extinction, which is already at least tens to hundreds of times higher than it has averaged over the past 10 million years.

The biosphere, upon which humanity as a whole depends, is being altered to an unparalleled degree across all spatial scales. Biodiversity – the diversity within species, between species and of ecosystems – is declining faster than at any time in human history.

Nature can be conserved, restored and used sustainably while other global societal goals are simultaneously met through urgent and concerted efforts fostering transformative change.” GBF page 4.

The framework sets out four global goals and 23 targets. Target 3 is particularly important. Known as the 30×30 target, it sets out to ensure that by 2030, 30% of all land and water on Earth are effectively conserved and managed. To put that in perspective, despite being the third most biodiverse country on the planet, only 9.2% of South Africa’s mainland is formally protected[1] (although that doesn’t include other effective conservation areas). It is also an important target as it is quantified with a timeline. The quantification of some of the global goals got watered down in the final version to words like ‘significant’, which are vague and don’t promote action.

So how do countries now meet these targets? Or show progress towards meeting them? National Biodiversity Strategies and Action Plans (NBSAP) are the principal instruments of implementing the CBD at a national level and provide for integrating conservation and sustainable use into national decision-making policy. Of the 196 parties to the convention, 185 have developed NBSAPs. You can access all of them, including South Africa’s, at https://www.cbd.int/nbsap/. So now South Africa and all the other parties must immediately begin to revise their existing NBSAPs to implement the GBF and show progress at COP16, to be held in the latter half of 2024. While this doesn’t give us much time, the EWT is working hard to contribute to the process so that we can measurably address biodiversity loss on the ground.

Dr Gabi Teren, the EWT’s National Biodiversity and Business Network Manager

EWT programmes like the National Biodiversity and Business Network are already working to accelerate meaningful dialogues around the business-centred targets, which aim to address the private sector’s role in destroying nature and to equip people to make responsible and sustainable choices. We had a large presence in Montreal, where I, as the Manager of the NBBN, was the MC of the B&B… sorry, the Master of Ceremonies of the official UN Business and Biodiversity Forum. It was an incredible privilege to give the opening speech to hundreds of business leaders, policymakers, and conservationists and introduce renowned global thinkers like the economist Jeffrey Sacchs and Hank Paulson, the ex-US Secretary of the Treasury, and high-profile CEOs and ministers. I spoke about Ubuntu and how the world needs to come together more than ever in the spirit of ‘I am because we are’. Covid taught us that in a crisis, we can mobilise entire nations overnight and disrupt entire value chains within days to go from making gin to hand sanitiser, and in the face of our planetary crisis, the biggest disaster humanity faces, we need to do more. You can view my impassioned speech and those of all the keynote speakers here (really worth a listen!).

The EWT also partnered with DFFE (Department of Forestry Fisheries and Environment) at an official side event, which we were lucky to get as hundreds of applications could not be accommodated. Supported by UNDP (UN Development Programme), BirdLife International, and the South African National Biodiversity Institute (SANBI). At this event, we spoke about the importance of collaborations between private-public-NGO bodies and how South Africa has some incredible success stories from such collaborations, such as the National EIA Screening Tool developed by SANBI, the EWT, – the world’s first biodiversity accounting framework for businesses to measure and disclose their footprints, which was proudly developed by the EWT with funding from Eskom. The audience’s reactions showed how these collaboration demonstrations could inspire action.

In a Post-2020 world, we need to work together to live more harmoniously with nature. Watch this space as we build that action to conserve our world with your help. In follow-up articles, I will unpack some key targets and how we plan to achieve them. Follow our socials here for more.

A tribute to a beloved pack member – Dr Peter Mundyn

Pioneering African Vulture Conservationist: 1941-2023

Dr John Ledger

While numerous tributes to Peter have poured in following his death on 3 February, it is regrettable that he did not get to write his own story, which would have been a fascinating autobiography. This is but a brief tribute to his full and exceptional life.

Born in  London, Peter showed early signs of leadership and self-motivation. In 1957 he became a Queen’s Scout and attended the World Jamboree. In 1960 he was a member of the British Schools Exploring Society expedition to Iceland, and in that year, he finished his schooling at the Royal Liberty School in Essex, winning a State Scholarship to Worcester College at Oxford University, where he ostensibly studied Zoology for a year.

But, in his own words, “he was not yet ready for such training”, and instead of zoology textbooks, he read Dostoevsky, learnt to play the saxophone, and had a fully wild time. Oxford divested itself of his continued presence. Thereafter followed time at the University of Life, where Peter undertook diverse types of work (including grave-digging) until he became a blues musician in the outfit called ‘Screaming Lord Sutch and the Savages’. The band toured in Europe, and Peter’s stories of those days were hilarious and unforgettable. But after a few years, he tired of the frenetic but jaded life of an itinerant musician and managed to get back into university, this time at King’s College, London, whence he emerged with a BSc (Hons) in Zoology in 1969. He started birding with his university friend Clive Slater (“when we were on a rather boring entomology field course”).

Then followed nearly three years in northern Nigeria, where he was a secondary school teacher (biology and mathematics) at the Government College in Sokoto. Here he became interested in vultures and, with another friend (Allan Cook), studied the Hooded Vultures that were abundant in the heart of the city and had developed a symbiotic relationship with the humans of Sokoto. After that, he became a junior research fellow at the University of Rhodesia in 1972 to pursue a doctoral study on the ‘Comparative Biology of Southern African Vultures’.

He researched vultures in the north-east of Rhodesia in the Chirisa and Chizarira Game Reserves and the south-east in the Gonarezhou Game Reserve. With his young assistant Gabriel Ruguma, he worked for three years in wild areas full of large and dangerous animals, armed with only a Swiss army knife. His tales about their escapades in the bush were entertaining, to say the least! To fulfil the broad scope of his research, Peter had to include the Cape Vulture (or Cape Griffon as he liked to call it) in his studies, and that brought him to South Africa, the stronghold of the species,  where we met in 1972 and became close friends for fifty years. I had been involved with ringing Cape Vultures with the Witwatersrand Bird Club when I was a student at Wits and a member of the university Mountain Club.

The following year Peter joined our annual expedition to ring Cape Griffon nestlings at Roberts Farm in the Magaliesberg, and with his sharp wit, combative world views, and vigorous usage of strong expletives, had a powerful impact on the young students of the Wits Mountain Club who had never encountered such an unusual character! Over the next few years, ringing efforts were extended to several Cape Griffon breeding colonies at Manoutsa, Colleywobbles (then Transkei), Zastron (Free State), and Botswana.

Peter also had a galvanising effect on several local vulture enthusiasts. Many people were attracted to work for vultures with the enthusiasm that he generated about the hidden charms and unique features of the big birds. The core of the Vulture Study Group (VST) comprised Mundy, Ledger, Russel Friedman (fundraising), Steven Piper (academic/statistician), Duncan Butchart (artist)  and Marilyn Blignaut (secretary). We funded the work of the VSG mainly by selling T-shirts at shopping centres, organised by our entrepreneurial ‘cousin’ Russel, and attracting the inquisitive crowds with a real live vulture called ‘Bonaparte (because of his crippled wing).

In 1976 we started reading about Clive Walker and the Endangered Wildlife Trust in various newspapers, and Mundy said he sounded like ‘the sort of bloke who might give us some money’. Clive was taken on a heart-stopping climb up the face of the Magaliesberg to see the vultures. He persuaded the Board that these young lunatics deserved support, and I was subsequently appointed as an EWT Trustee in 1976 with a brief to make sure the Vulture Study Group was run with business-like discipline, and it became the first ‘Working Group’ of the EWT.

Peter Mundy, John Ledger, Dr Leslie Brown, Dr Ian Newton, Russel Friedman, Dr Alan Kemp; seated: Steven Piper and ‘Timofy Vulcha’.

At a South African Ornithological Society (SAOS) symposium on ‘African Predatory Birds’ at the Transvaal Museum in August 1977, we interacted with an audience that included leading specialists like Dr Leslie Brown from Kenya and Dr Ian Newton from Oxford University. Two years later, in 1979, Peter, Russel, and I attended and made presentations at the first International Conference on the Vultures, held in Santa Barbara, California. Our participation put the Vulture Study Group on the international map and resulted in us working with the California Condor Rescue Programme in 1981 and attending a Bird of Prey conference in Thessaloniki, Greece, in 1982.

Peter graduated with a D Phil from the University of Zimbabwe in 1981 and was employed by the EWT as its first Scientific Officer. He later joined the Department of National Parks and Wildlife in Zimbabwe as their Ornithologist and also represented his country at various international meetings such as CITES. Peter and I attended several vulture conferences around the world and met regularly on his visits to South Africa.

He was subsequently appointed Professor of Forestry and Wildlife at the National University of Science and Technology in Bulawayo, where he played a major role in training young Zimbabweans, many of whom went on to remarkable achievements at the tertiary level and employment in the fields of biology and conservation. He was an excellent and prolific writer and published numerous popular and scientific articles. The ultimate milestone was the publication of The Vultures of Africa in 1992, authored by Peter Mundy, Duncan Butchart, John Ledger and Steven Piper. The citation index for this large 464-page book is remarkable and continues growing to this day.

When Peter was diagnosed with cancer, he came to Johannesburg several times for treatment, where we saw one another and also made two rather nostalgic visits to the Magaliesberg in 2021, one to the Nyoka Ridge vulture restaurant on International Vulture Awareness Day on 4 September, and another to Vulpro on  Heritage Day, 24 September. What struck me about these gatherings was how Peter Mundy’s legacy has inspired future generations of people to appreciate and treasure these great birds and go to great efforts to conserve and care for them. This is a notable achievement that will long be associated with this remarkable man and will hopefully be a solace to his wife Verity and children Matthew and Emily as they come to terms with their loss. I certainly miss him deeply.
