Western chimpanzees (Pan troglodytes verus) may be present in Boi Tano Forest Reserve.
No chimpanzees were recorded in the last survey.
The chimpanzee population trend is decreasing.
The site has a total size of 129 km².
Key threats to chimpanzees are hunting and logging.
Conservation activities are not documented.

Site characteristics

The reserve is located in southwestern Ghana, forming a continuous forest block with Tano Nimiri Forest Reserve in the northeast. It was declared a forest reserve in 1967 (Gatti 2009). The vegetation is mainly wet evergreen forest. Access to the reserve is difficult because of the many watercourses, with two main rivers, the Tano and the Bisao, crossing the reserve and resulting in much swamp habitat (BirdLife International 2022).

Ape status

During a rapid survey in 2009, no signs of chimpanzees were documented; however, hunters reported chimpanzee sightings and signs, and a population may still exist in the contact zone between Tano-Nimiri and Boi Tano (Gatti 2009).

Category	Specific threats	Threat level	Description	Year of threat
10 Geological events		Absent
12 Other threat		Absent
5 Biological resource use	5.1 Hunting & collecting terrestrial animals	High (more than 70% of population affected)	High abundance of hunting signs and low encounter of mammal species, especially large (Gatti 2009).	Ongoing (2009)
