Ape status

There exist no recent estimate of chimpanzee abundance in Ghana. The last estimate was made by TelekiĀ“s (1989), which estimated between 300 to 500 chimpanzees to be present in Ghana. No evidence of chimpanzee's presence was found at this site during field surveys, however their presence was reported by hunters (Magnuson, 2002; Oates, 2006).

This forest has been heavily logged in the past. Evidence of logging in progress was also seen during field surveys in 1995 (Oates, 2006). Evidence of hunting is high at this site. It was estimated to 5.2 hunting signs per hour of scouting survey (Oates, 2006).

Several primate surveys have been conducted at this site, the most recent having been conducted in 2005 (Oates, 2006). These surveys were not specifically focused on chimpanzees, but they provide the most up-to-date information available to their current distribution and status.
