The site is located in the Ekiti state in Nigeria. Chimpanzees have not been observed in the reserve since 1993, and in its current condition it holds little value in terms of its natural biodiversity. Due to extensive farming, the site has in effect become unofficially de-gazetted (Greengrass 2006).
