Abstract: We used line transects to survey chimpanzees (Pan troglodytes verus) and threatened monkeys in the BiaGoaso Forest Block (BGFB) in Southwestern Ghana. Based on nest counts, we estimated a density of 0.26 chimpanzees per km² (SE = 0.25, CV = 111.7%) and an average nest encounter rate of 0.29 nests per km. We directly encountered 16 monkey groups (encounter rate of 0.12 groups per km), which included four species of diurnal monkeys: Lowe’s monkey (Cercopithecus campbelli lowei), lesser spot-nosed monkey (Cercopithecus petaurista petaurista), black and white colobus (Colobus vellerosus) and olive colobus (Procolobus verus). More than half of our monkey encounters involved polyspecific groups. The distribution of chimpanzees was clumped and their range was restricted to only five out of the 14 reserves surveyed, while that of the monkeys was much extensive for the different species, extending from nine to eleven of the 14 reserves surveyed. We found signs of hunting activity throughout the BGFB, with the majority being wire snares.
