- Hunting is the main threat to chimpanzees.
- Conservation activities have focused on wildlife research and livelihood improvement initiatives.
Site characteristics
Korup National Park is located in western Cameroon, bordering Cross River National Park in southeast Nigeria (BirdLife International 2021). The site was established as a forest reserve in 1962 and upgraded to a national park in 1986 (Morgan et al. 2011, BirdLife International 2021). Altitudes range from just above sea-level to over 1,000 m but the terrain is generally flat, with hills and escarpments found only in the northern section of the park; the highest peak (Mount Ekundukundu) is situated in the centre of the park (BirdLife International 2021). The forests of Korup are floristically diverse and the annual average rainfall is approximately 5,460 mm. The diversity of birds is relatively well known, with some 320 species recorded in and on the margins of the site, including a large number of species of the Guinea–Congo Forests biome (BirdLife International 2021). Mammals of conservation concern found at the site include mandrills (Mandrillus leucophaeus), Preuss's monkey (Cercopithecus preussi), and forest elephant (Loxodonta cyclotis). The occurrence of Preuss's red colobus, Procolobus (badius) preussi, is of special importance (Morgan et al. 2011, BirdLife International. 2021).

Ape status
Two surveys were conducted in logged and unlogged sites in the Korup Project Area, which consists of the Korup National Park and the surrounding Support Zone (5,357 sq.km), where two logging concessions had been active between 1996-1998 (Waltert et al. 2002). The results of the survey showed that between 1999-2000 and 2000-2001, chimpanzee (as well as other primate) density decreased in the logged sites (Waltert et al. 2002).

Threats
Hunting is a major threat to chimpanzees and other mammals in Korup National Park (Morgan et al. 2011, Hofner et al. 2020). Pressure on the park's wildlife is high due to the dependence of local on bushmeat, and the demand for bushmeat in neighbouring Nigeria (Diotoh n.d.). In addition, 70,000 ha of the park's bufffer zone, which were once traditional hunting grounds, have been converted into oil palm plantations (Diotoh n.d.).

Conservation activities
The Korup Rainforest Conservation Society (KRCS) is a community based organisation in Southwest Cameroon that was created in 2009. KRCS supports and implements various conservation activities, especially related to wildlife research and livelihood improvement initiatives such as donating farming equipment and community infrastructural development (KRCS).
