The Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti) is a subspecies of the common chimpanzee which inhabits the rainforest along the border of Nigeria and Cameroon. Male Nigeria-Cameroon chimpanzees can weigh up to 70 kilos with a body length of up to 1.2 metres and a height of 1.3 metres. Females are significantly smaller.[2]

Conservation[]

The Nigeria-Cameroon chimpanzee is recognised as the most threatened and least distributed of all the common chimpanzee subspecies, and without a dramatic change to human behaviour in the area, there is a likelihood of extinction in the coming decades.[3] A June 2008 report said the Edumanom Forest Reserve was the last known site for chimpanzees in the Niger Delta.[4]

Subpopulations[]

The Nigeria-Cameroon chimpanzee is found in:[1]

During a 2006 survey in southwestern Nigeria, the Nigeria-Cameroon chimpanzee was found in Idanre Forest Reserve, , Oluwa Forest Reserve, Omo Forest Reserve, Ise Forest Reserve, , and Okomu National Park.[6] Chimpanzees were found in Ondo State, Ekiti State, Edo State, and Ogun State. Later surveys also confirmed chimpanzees to be present in .[7] This population is on the verge of extinction. The genetic affiliations of this population are also unclear.
