This site comprises a discontinuous arc of forested hills to the north and west of Yaoundé, situated 10–35 km from the city centre. Four main hills are included; Mbam Minkom, the largest, to the north-west, Nkol Yéyé due north of Yaoundé, Eloumden to the south-west and, beyond it, Kala, furthest from the city. Some good forest remains, but it is fragmented and highly threatened. The vegetation includes degraded, drier semi-evergreen and mixed moist semi-evergreen rainforest with some mid-altitude elements. Average annual rainfall is between 1,600–1,700 mm.
See Box and Tables 2 and 3 for key species. The avifauna of the region as a whole, including non-forest forms, totals about 360 species.
Non-bird biodiversity: None known to BirdLife International.
Pressure/threats to key biodiversity
The Cameroon Ornithological Club is considering the possibility of developing a conservation project in the area. The local forests are fragmented and highly threatened by local timber extraction, farming and hunting; most of the large mammal populations have already been lost.
