The site is made up of the mountain massif in the north-centre of Mayotte, dominated by two peaks—Mtsapéré (also called Majimbini, 572 m) and Combani (477 m)—connected by a ridge that does not drop below 320 m. The terrain is mainly undulating, although steep slopes occur around Mtsapéré. The site includes most of the land above 200 m, although cultivation that extends higher than this (especially around the towns of Vahibéni and Combani) is excluded. The nearest towns are Mamoudzou to the east and Combani to the west; this site contains the catchment for both. The area contains the largest expanse of forest on Mayotte. Vehicle tracks lead almost to the tops of both mountains, and an antenna is sited near the top of Mtsapéré.
See Box and Table 2 for key species. The site contains the full community of forest-living birds (around 14 species) of Mayotte. Most are common and are not restricted to forest, but the two pigeons are forest-dependent. By virtue of its large extent, this site may be the most important for Dicrurus waldenii. Additional species occur in the cultivated land and villages around the forested area.
