Studies in the Wild
Currently, there is only one long-term study of the Nigeria-Cameroon chimp led by Volker Sommer, a Swiss primatologist. This study is being carried out in the Northernmost range of the species in Nigeria, at Gashaka-Gumpti National Park. A number of other short-term studies and field surveys to assess wildlife in some areas of Nigeria and Cameroon include collecting data on wild chimpanzees and can be read about here.
