The future of the Maasai Mara’s threatened population of vultures is looking a little more robust, thanks to a unique collaboration involving Narok County Council, the National Museums of Kenya, and safari guides from the three Mara properties managed by Heritage Hotels.
The Mara Vulture Project, launched in July 2003, has now entered a third phase, with data collected over the past four years being compiled in the first comprehensive database of vulture dynamics and behaviour ever established in East Africa. The data will help to support a major grassroots education campaign being launched in the wider Mara-Serengeti to inform conservationists, tour operators, visitors and local communities about the vital importance of these vulnerable birds to the long-term health of the ecosystem.
Vultures have long been a misunderstood and undervalued species, but all that is now changing. Since July 2006, the Mara project has been following a number of locally tagged birds to determine their foraging and breeding ranges. Vultures tagged in the Mara have since been reported in Ngorongoro, Athi River, and as far as Laikipia. To date, a total of 42 vultures have been tagged – allowing a unique glimpse into the mysterious world of these enigmatic birds.
Vultures play a critical ecological role in the Mara-Serengeti through their consumption of up to 70% of all large ungulate carcasses, ridding the environment of potential disease-causing organisms that could threaten the survival of many other species. In recent years, populations of vultures have been reported in decline across Africa due to poisoning, persecution, and threatened food sources and nesting habitats. At least three species of Gypsvultures in South Asia are now listed as ‘critically endangered’ in IUCN’s Red Data Book due to poisoning from livestock carcasses contaminated by the pharmaceutical drug diclofenac, which have caused vulture populations to crash by as much as 95%.
Vultures in East Africa face a similar threat from the poisoning of terrestrial predators and contaminated livestock carcasses. A catastrophic collapse of vultures in the Mara-Serengeti would have dire ecological consequences for the future of the two reserves, and it is hoped that a better understanding of the species will help to design scientifically sound conservation and management strategies to ensure their survival.
