Site description The site is situated in the south-east of the country, close to the border with Cameroon, to the north-east of Cross River National Park—Okwangwo Division (NG010). The area is wet and mountainous with a plateau at about 1,500 m and peaks which rise to 1,700 m, and is a western extension of the Cameroon mountain range. It comprises a large area of montane grassland criss-crossed by numerous perennial mountain streams flowing through valleys. These valleys support patches of relict montane forest. Typical plants include Andropogon distachyos in the grasslands and various Ficus spp., Polyscias fulva and the tree-fern Cyathea manniana in the forests. Forest trees are often festooned with epiphytes. A state-owned cattle ranch covers part of the area, while the remainder of the land is owned by local communities. Access is via an asphalted road from the nearby town of Obudu. The wet season lasts from March to November and average annual rainfall is about 4,200 mm.

Other biodiversity The primate Cercopithecus preussi (EN) still occurs; Gorilla gorilla (EN) at least used to do so, and is thought to visit the area seasonally, crossing from neighbouring Cameroon during the wet season. Some 52 of Nigeria’s 550 nationally endangered plants are found on the Obudu Plateau.
