Can Artificial Intelligence Help Pinch Poachers?
31 October 2019
In the uMkhuze section of iSimangaliso Wetland Park, part of the Lubombo Transfrontier Conservation Area, elephants are flourishing. Following the reintroduction of the species into the game reserve during the 1990s, the numbers rapidly grew to a healthy 139 strong elephant population today. In a world where more than 30 000 elephants are lost to poaching each year, this is a true management success story for conservation partner Ezemvelo KwaZulu-Natal Wildlife, but one that, unfortunately, now has also started to present its own challenges. This is because uMkhuze, one of South Africa’s oldest game parks (est. 1912), only offers a range of 43 000 ha with a finite carrying capacity for these gentle giants.
Only 150 kilometers to the west of uMkhuze, Ezemvelo’s Ithala Game Reserve struggles with the same challenge of effectively maintaining their blossoming elephant population within the reserve’s approximately 30 000 ha protected area.
“There are various ways in which an overpopulation of elephants can be managed. This includes culling, contraceptives, as well as translocations. In both uMkhuze and Ithala, contraceptive plans have already been put into action. This will, however, take time to significantly contain numbers – time that the reserve does not have as the tightly contained herds of elephants start to disrupt ecosystems and diminish resources,” explained Dave Cooper, Wildlife Veterinarian for Ezemvelo.
Accordingly, last week, expert teams from Elephants, Rhinos & People (ERP – erp.ngo), Conservation Solutions, and Ezemvelo, supported by the Department of Environmental Affairs, came together to capture 29 of the uMkhuze and 24 of the Ithala elephants and transport them safely through a 1 250 km journey with greater purpose. By removing a significant percentage of the elephant population from the reserves, it potentially negates any need for further extreme elephant management interventions for at least the next 10 to 15 years.
The elephants crossed two borders and traversed three countries (South Africa, Swaziland and Mozambique). Less than two days later, they were released into the care of Peace Parks Foundation and Mozambique’s National Administration for Conservation Areas who co-manage the elephant’s new home – Zinave National Park.
iSimangaliso’s Park Operations Director Sizo Sibiya – who in 1994 was a section ranger at uMkhuze when the elephants first arrived – commented: “We must remember that protected areas are managed not only for the benefit of specific species, but rather holistically for all biodiversity. In the case of the flourishing uMkhuze elephant population, their numbers are reaching a point where a noticeable impact can be seen on the trees. This proposal to donate some of them to Zinave was a win-win solution for all of us.”
ERP, supported by groupelephant.com, funded and coordinated the translocation operation as part of their drive to translocate large elephant numbers outside of South African borders, to alleviate the country’s increasing elephant population pressures. Helicopter time and fuel was sponsored by Wild Tomorrow Fund.
Lise-Marie Greeff-Villet, Communications Coordinator for Peace Parks Foundation, shared: “Observing the elephant capture operations was like watching a well-choreographed dance. It was breathtaking to see the skill with which game capture teams, veterinarians, rangers, pilots, and drivers coordinated their responsibilities; and even more beautiful the passion and care that accompanied every interaction with, and touch of, an elephant.”
Zinave, situated within the Great Limpopo Transfrontier Conservation Area, offers a protected space of 408 000 ha with prime elephant habitat, more than sufficient water resources, and only a handful of local elephants – positioning the uMkhuze and Ithala elephants to proliferate as the progenitors of a thriving new elephant population. The new elephants will bring the total elephant population in the Park to about 67, a number that is expected to double over the next 10 years.
The elephants will initially be released into an electrically-fenced 18 600 ha sanctuary. This will allow them to settle into their new environment and be introduced to the family herd that has been resident in the sanctuary for the past year. Safeguarding the wildlife within Zinave is of course paramount to Park management. Through significant funding from Peace Parks Foundation, the Park’s protection capabilities were recently reinforced with 26 newly trained and appointed rangers, ranger base camps, patrol equipment and digital communication systems – all as part of advanced and integrated anti-poaching strategies.
The ‘destructive’ behavior that resulted in the elephants’ move from uMkhuze and Ithala, is exactly what will now benefit the ecosystem balance in Zinave. With almost no wildlife present in the Park for decades, the vegetation has become extremely overgrown and dense. Peace Parks Foundation has been rewilding the conservation area for the past few years and the close to 1 250 animals, mostly grazers, brought in have already started to change the flora landscape for the better. However, the elephants will now take this to a whole new level.
As Bernard van Lente, Peace Parks Foundation’s Project Manager in Zinave, notes: “The elephants will stimulate biodiversity by trampling and, thereby, opening up space in overgrown areas, allowing for other species of grasses and smaller saplings to gain access to sunlight, currently blocked out by dominant, larger tree species. The spaces opened up by elephants will also create pathways for other species and expose grasses and flora for these grazers to eat, food that would otherwise have been inaccessible. In addition, the proliferation of other insects attracted to elephant dung also provides food for birds and bats, which in turn helps spark the increase in other species, known as ‘succession’.”
‘’We are very excited about the positive impact these cross-border elephant translocations will have on reducing elephant population pressures in South Africa, whilst establishing new populations in areas such as Zinave National Park. This is also the first of what will hopefully be many more meaningful projects conducted by ERP in Mozambique in collaboration with Peace Parks Foundation‘’, said Dereck Milburn, Director Operations for ERP.
Rewilding Mozambique’s protected areas is a primary focus in Peace Parks Foundation’s strategy for the development of transfrontier conservation areas in the region, with repopulated parks hopefully leading the way in revitalising the country’s eco-tourism economies.
Zinave National Park
In September 2015, Peace Parks Foundation signed an agreement with the Government of Mozambique through the National Administration for Conservation Areas for the co-management and development of Zinave National Park as part of the Great Limpopo Transfrontier Conservation Area. Peace Parks Foundation’s work in Zinave, which commenced in January 2016, is funded by a philanthropic donor, who has made a financial commitment over a 10-year period (2016 – 2025) to invest in restocking the park, supporting conservation efforts, facilitating tourism development and investing in community development.
ERP and PPF
In 2018, ERP recently entered into a Memorandum of Understanding with Peace Parks Foundation to take on the role of the Foundation’s strategic elephant management partner in Mozambique.
