Français | Português | Español | Bahasa Indonesia | Melayu
Summary
- 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 (Dunn et al. 2014).

Ape status
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 (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 (Dunn et al. 2014). A few gorilla nest sites have been found at two sites outside the boundaries of the reserve (Dunn et al. 2014).

Threats
The main threats to the gorillas in this area are poaching and habitat loss (Dunn et al. 2014).
