Abstract. This paper explores the ecology and conservation issues of five threatened primate species inhabiting the Dja Faunal Reserve in Cameroon: the western lowland gorilla (Gorilla gorilla gorilla), central chimpanzee (Pan troglodytes troglodytes), drill (Mandrillus leucophaeus), mandrill (Mandrillus sphinx), and white-collared mangabey (Cercocebus torquatus). The main goal is to assess their ecological status and identify key conservation challenges affecting their long-term survival. A descriptive analytical method was applied, combining literature review, field survey reports, and conservation data from international organizations such as UNESCO, IUCN, and the Zoological Society of London. The study reveals that although the Dja Reserve is a UNESCO World Heritage Site and one of Central Africa’s most important protected areas, its biodiversity remains under threat from illegal hunting, habitat loss, weak law enforcement, and limited funding. Findings emphasize that the success of conservation initiatives depends largely on strengthening anti-poaching measures, increasing the conservation budget, and providing regular training for eco-guards and management personnel. Additionally, the research underscores the importance of environmental education and community participation in promoting sustainable resource use and reducing dependence on bushmeat. While constrained by limited recent field data, the study’s novelty lies in integrating ecological, socio-economic, and governance perspectives to propose actionable, context-specific solutions. The implications are significant for policymakers and conservation practitioners seeking to enhance biodiversity management and ensure the long-term protection of primate populations within the Dja landscape and across Central Africa.
