Cameroonian Highlands forests


The Cameroonian Highlands forests are a montane tropical moist broadleaf forest ecoregion located on the range of mountains that runs inland from the Gulf of Guinea and forms the border between Cameroon and Nigeria. This is an area of forest and grassland which is becoming increasingly more populous as more and more land is cleared for agriculture.

The Cameroonian Highlands forests extend across the Cameroon Highlands, a chain of extinct volcanoes, covering an area of 38,000 square kilometers (15,000 sq mi) in eastern Nigeria and western Cameroon. The ecoregion lies above 900 meters elevation, and is surrounded at lower elevations by the Cross-Sanaga-Bioko coastal forests at the southern end of the range, and by forest-savanna mosaic along the central and northern ends of the range; the Cameroon Highlands form the boundary between the Guinean and Northern Congolian forest-savanna mosaic ecoregions. The highest mountain in the chain, Mount Cameroon is considered a separate ecoregion, while the highest peak within the region is Mount Oku (3,011 metres (9,879 ft)). As with similar highland areas in Angola and in East Africa the climate is cooler here than is typical of tropical Africa. The highlands are an important source of water for both Nigeria and Cameroon.

The vegetation varies with elevation. Submontane forests extend from 900 metres (2,953 ft) to 1,800 metres (5,906 ft) meters elevation. Above 1,800 metres (5,906 ft) elevation are distinct montane forests and patches of montane grassland, bamboo forest, and subalpine grasslands and shrublands. The ecoregion is characterized by the presence of afromontane species, which have an archipelago-like distribution across the highlands of Africa. Typical afromontane species are Nuxia congesta, Podocarpus latifolius, Prunus africana, Rapanea melanophloeos, and Syzygium guineense bamendae.
