Site

Mamiri Forest Reserve covers an area of 45 km2 immediately south of the town of Sureso. It was constituted as a reserve in 1949. It has a long, narrow shape, extending for about 15 km from north to south, and only 2-4 km from east to west (Oates, 2006). Mamiri lies on the boundary between the Wet Evergreen and Moist Evergreen forest zones (Hall and Swaine, 1981).

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. Chimpanzee's presence was confirmed during field surveys in 2005 at this site (Oates, 2006), however recent surveys in 2009 failed to confirm their survival at this site today (Gatti, 2009).

Threats

Hawthorne & Abu-Juam (1995) reported that Mamiri was last logged in 1973. Samartex Timber and Plywood Ltd was granted a 40-year concession to log Mamiri in 1997, relinquished this in 2001, then later took the concession back (FC Regional Planning Team, 2001; Forest Office, Asankrangwa; cited in Oates, 2006). Hunting is prevalent at this site, but not excessive, probably due to low mammal densities which render this activity uneconomic for local hunters (Oates, 2006).

Surveys

During field surveys in 2005, three nests were seen in the northern part of Mamiri (Oates, 2006). However, during recent 'recce' along 88km in 2009, no signs of chimpanzee's presence were found (Gatti, 2009).
