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 Yuhan) is situated in the centre of the park. The forests of Korup are floristically diverse and the annual average rainfall is approximately 5,460 mm (Chuyong et al. 2004). 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), and forest elephant (Loxodonta cyclotis). The occurrence of Preuss's red colobus, Piliocolobus 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 locals on bushmeat, and the demand for bushmeat in neighbouring Nigeria (Robinson 2014). Since 2017, the wildlife and habitats of Korup National Park have been affected by a civil war as rebel groups in the forests have prevented access for government personnel, such as ecoguards, allowing local people and Nigerians to remove resources unhindered (Kupsch & Tamo 2023, Kupsch et al. 2024).

Conservation activities
Korup National Park is under the administration of the Cameroonian Ministry of Forestry and Wildlife (MINFOF), which is supported by the PSMNR-SWR development program and follows a collaborative management approach (PSMNR-SWR n.d.). In addition to support for infrastructure, households, education and training, this also includes protection activities such as demarcation and patrolling, as well as bio-monitoring (Kupsch & Tamo 2023). In addition to communities and their members, community-based organizations are also involved in management. Some of them also carry out independent projects, such as the Korup Rainforest Conservation Society (KRCS), which 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).

Challenges
Conflicts between park staff and local communities due to inadequate flow of information (Robinson 2014). Since 2017, there has been a military-political crisis with a very poor security situation in the Anglophone regions of Cameroon, which has made law enforcement impossible, particularly in Korup National Park. Eco-guards and researchers cannot enter the national park and most of the villages within and adjacent to it (Kupsch & Tamo 2023).

Research activities
Due to the proximity to the Korup National Park headquarters in Mundemba and the establishment of good research and tourism infrastructure, e.g. chimpanzee camp, the wildlife populations of the southern part of the park are the best studied (e.g. Astaras et al. 2017, Boekee & Robinson 2018, Kupsch & Tamo 2023). There is also good access via Mamfe in the northeast of the park, making it a local focus for wildlife research. (Waltert et al. 2002, Hofner 2020). The remaining parts of the park were surveyed in 2007 and 2014 by a park-wide, transect-based wildlife monitoring program (see Kupsch & Bobo 2024), funded by the development program PSMNR-SWR (PSMNR-SWR n.d.). The community-based organization KRCS supports international researchers and the national park administration in the implementation of conservation research activities, which mainly focus on biomonitoring, socio-economic surveys, and primate research, and also carries out own projects (KRCS n.d.). However, due to the ongoing military-political crisis and the high level of insecurity in the Anglophone regions, all research activities in the park were suspended in 2017. In 2022 and 2023, PSMNR-SWR successfully introduced low-risk community-based wildlife monitoring by training community members as surveyors under the guidance of the local organization KRCS (Kupsch & Tamo 2023). In 2023, PSMNR-SWR conducted its first own surveys in the south of the park in collaboration with KRCS (Kupsch et al. 2024). However, due to the worsening crisis situation since the end of 2023, all monitoring activities have been put on hold for the time being.
