Research activities
Research activities are conducted at UFA 10-065, primarily led by the Wildlife Conservation Society (WCS) and MINFOF. These include long-term population monitoring of great apes using transect surveys and nest counts, focusing on density and habitat use. Additional research examines human impacts, such as logging and poaching, on ape populations and biodiversity (Maisels et al., 2013). No permanent research station is reported, but continuous field activities provide valuable data for adaptive management. The site serves as a critical location for understanding ape ecology and guiding sustainable conservation practices within logging concessions.
