* Nigeria-Cameroon chimpanzees (''Pan troglodytes ellioti'') & Cross river gorillas (''Gorilla gorilla diehli'') are present in Mone River Forest Reserve.
* It has been estimated that 20-30 gorillas occur in the site.
* The great ape population trend is unknown.
* The site has a total size of 538 km².
* Key threats to great apes are poaching and habitat loss due to logging and expansion of cocoa farms into the reserve.
* Conservation activities are not documented.

= Site characteristics =

Mone River Forest Reserve is located approximately 7 km southeast of Takamanda National Park. The forest reserve was established in the 1950s. The landscape is topographically diverse, with hills rising from 350 m to almost 1,000 m above sea level ([[#R01231|Dunn et al. 2014]]).

The presence of gorillas in the reserve was only confirmed in 2000, with the discovery of a population in a mountainous region in the extreme northeast of the reserve, close to the village of Mbu ([[#R01231|Dunn et al. 2014]]). Surveys in the north of the reserve have determined that gorillas use a relatively large area (100 km²), extending from the center of the reserve to the northern border and continuous with the gorilla range in the Mbulu-Mt. Oko region ([[#R01231|Dunn et al. 2014]]). A few gorilla nest sites have been found at two sites outside the boundaries of the reserve ([[#R01231|Dunn et al. 2014]]).
