Location Equatorial Guinea, Bioko
Central coordinates 8o 45.00' East  3o 35.00' North
IBA criteria A1, A2
Area 33,000 ha
Altitude 800 - 3,011m
Year of IBA assessment 2001

Site description Located in the northern half of Bioko island, the area, designated a National Park in 2000, comprises the montane area of Basilé Peak, above the 800 m contour. Relief is extremely rugged. The vegetation comprises montane forest and, at highest altitudes, montane bushland and thicket, and is relatively undisturbed. There are no settlements above 800 m, but levels of human activity on the site are high. There is a trail up the north-eastern slope to a radio booster-station on the summit.

Key Biodiversity See Box and Table 2 for key species. A total of 70 bird species, all thought to be resident, have been recorded. These include, in addition to the endemic Speirops brunneus which is restricted to this site, 28 species which occur as endemic races on Bioko. It is possible that Picathartes oreas may yet be found in the less explored areas.

Non-bird biodiversity: Five species of primate of global conservation concern occur—Cercopithecus preussi (EN), C. erythrotis (VU), Colobus satanas (VU), Procolobus badius (LR/nt) and Mandrillus leucophaeus (VU)—as does the ungulate Cephalophus ogilbyi (LR/nt). One fish and three reptile species are endemic to the island.
