Site characteristics

Boundialé-Odienne is an area that was surveyed as part of the Pan African Programme (PanAf). The site is characterised by subtropical dry forest and savanna, punctuated by inselbergs and wet gallery forests (Cohen, H. pers. comm. 2022). The area encompasses numerous classified forests.

Ape status

A minimum of two nests and two faecal samples were recorded during a 2015 survey; local villagers reported the presence of chimpanzees (Cohen, H. pers. comm. 2022). Community members were questioned in 30 villages associated with 20 classified forests.

Pan troglodytes verus	2015	Present				Boundialé-Odienne	Line transects & recces		Cohen, H. pers. comm. 2022	Recce (covering less than 20 km) and interview survey.

Threats

The classified forests in the area have not been managed, and most of them are simply demarcations on a map, so the forests have been severely degraded (Cohen, H. pers. comm. 2022).
