Vultures to track animal poisoning in Africa
Using vultures to track and combat wildlife poisoning on the African continent.
Gyps africanus (White-backed vulture)
The Great Limpopo Transfrontier Park (GLTP) including the Limpopo National Park (Mozambique), Gonarezhou National Park (Zimbabwe) and Kruger National Park (KNP) represents a strategically important, vulture-rich landscape. The 35 square kilometer wilderness represents one of the most significant protected areas on the African continent.
Unfortunately, wildlife poisoning is a massive threat with vultures impacted more than other species. An estimated 450 vultures of four threatened species have been poisoned in the KNP since January 2019.
To reduce the loss of vultures to poisoning, the project team needed to track them within the GLTP to monitor their movements and unique foraging and feeding signatures. Tracking their movements allows alerts to be shared with rangers about large mammal deaths possibly through poisoning.
The MBZ Fund grant made the project possible and massively successful as we managed to deploy 66 GPS-tracked vultures and obtained 97% coverage of the targeted area. They developed an effective, automated system to push culture feeding and immobility alerts, enabling them to ground truth over 350 feeding event alerts of which 89% were positive carcass hits. These alerts are sent to wildlife monitoring platforms like EarthRanger. The “eye in the sky” has become an essential conservation tool to reduce the devastating impact of wildlife poisoning. The programme was well received, and the team have fully functional systems being used across eight African continents with over 180 birds tracked.
