The proposed national parks of Boumba-Bek and Nki cover over 8,000km2 and constitute the largest contiguous block of protected forest in Cameroon.

The area is characterized by intact lowland rain forest harboring significant populations of large mammals, including forest elephants, gorillas and chimpanzees. Its relative isolation from traditional population settlements has thus far ensured a certain degree of protection for its wildlife populations.

However, the zone is currently surrounded by commercial forestry concessions. The presence of mineral exploitation and a national road to its northern periphery pose a considerable threat to ape populations and other wildlife as a result of commercial hunting and human encroachment.

The illegal trafficking of military weapons facilitates gorilla poaching in the area.
