Wildlife Conservation Society to manage key Nigerian wildlife reserve
Yankari Game Reserve in Nigeria, which includes the Country’s main remaining population of elephants, is to be managed by The Wildlife Conservation Society in partnership with the Bauchi State Government for the next four years
The 866-square-mile (2,244 square kilometers) reserve contains an estimated 350 elephants, – the only viable population remaining in Nigeria and one of the largest remaining in West Africa. The area also supports important populations of lion, buffalo, hippo, roan antelope, and hartebeest. It is considered the nation’s richest protected area.
“Yankari Game Reserve is an ecological gem of West Africa,” said Dr. James Deutsch, Executive Director of WCS’s Africa Program. “We are extremely proud to be entrusted with preserving this critically important wildlife area by the Governor of Bauchi State, Malam Isa Yuguda for the benefit of the people of Bauchi State and Nigeria.”
