Site characteristics
Mbam et Djerem National Park was established in 2000. The park is situated in central Cameroon, within the Guinea-Congolia/Sudania regional transition zone, between the Sudanian regional center of endemism in the north, and the Guinea-Congolian forest block in the south. The vegetation at Mbam et Djerem National Park grades from savanna in the northwest to forest-savanna mosaic, to the closed-canopy humid forest in the southwest. It is the most biologically diverse protected area in the country due to its exceptional habitat diversity (WCS). Mbam et Djerem National Park is home to two subspecies of chimpanzees, (central and Nigeria-Cameroon chimpanzees), De Brazza's monkeys, elephants, buffalos, hippopotamus, leopards, and over 65 reptile and 365 bird species (BirdLife International 2020, WCS).
