Site description This site, centred on the volcanic Mount Luba in southern Bioko, is one of the wettest places in the world; annual rainfall may reach 10,000 mm. It includes the only undisturbed lowland forest on Bioko which merges, in an unbroken catena, into montane forest above 800 m. The terrain is extremely rugged. There is one village within the reserve, with fewer than 200 inhabitants, while some 2,000 people, living along its borders or close to them, make use of the site.
