Geography
Country: Cameroon
Coordinate: 3° 57' N, 11° 23' E
Coordinate basis: estimated from map
Geography comments: "10km on the western side of Yaoundé city" and specifically "12 summits of hills located in the 1000-1295m altitude in the Mbam Minkom massif" (altitude is the midpoint of exact values stated in the text)
Environment
Habitat: tropical/subtropical dry broadleaf forest
Substrate: ground surface
Disturbance: hunting
MAT: 23.8
WMT: 25.0
CMT: 23.0
MAP: 1605.0
Habitat comments: "The mean annual rainfall was around 1605mm at Yaoundé, but could be more in the study area due to its geographical situation, its altitude and the forest. The dry season lasts about 3 months... Current disturbance is minimal except for hunt of the small vertebrates and the harvest of the non woody forestry products"
