Located on the southern slopes of the Adamaoua plateau, to the east of the Yoko–Tibati road, Mbam Djerem National Park has probably the greatest habitat diversity of any protected area in Cameroon. The vegetation includes the northern limits of the rainforest, riverine and gallery forest, savanna woodland and some riverine grassland. The terrain is generally flat and is drier and more open to the north and west. The area in the south of the park used to be more open, due to frequent fires, but now there are extensive areas of woodland and young forest. It is apparent from old vegetation maps and more recent satellite imageries that much of the forest in the area is only about 50 years old; between 40–50% of the park is now forested. Average annual rainfall is approximately 1,500 mm.
See Box and Tables 2 and 3 for key species. The avifauna is rich, with 365 species recorded so far. One species of the Afrotropical Highlands biome (A07) also occurs (see Table 3).
Non-bird biodiversity: The area still holds relatively healthy populations of a number of large mammals including Pan troglodytes (EN), Loxodonta africana (EN) and Hylochoerus meinertzhageni (VU).
