Cherangani Hills Forest (Cherangany Hills Forest) is a collection of thirteen forest reserve blocks in western Kenya, located in the Cherangani Hills on the western ridge of the East African Rift. The forested area is about 1,200 square kilometres (463 sq mi),[1] 956 square kilometres (369 sq mi) of which has been gazetted into forest reserves.[2] These forest reserves form the upper catchments of the Kerio and Nzoia and Turkwel rivers.[1]

Forest types[]

The three western blocks, Kapkanyar, Kapolet and Kiptaberr, are larger and more consolidated and constitute about 20% of the Cherangani Hills Forest. Most of the rest of the forests are fragmented, cut by grasslands, bushlands, and croplands.[2] The forests themselves are quite varied in composition. To the west, the lower elevations are "Aningeria-Strombosia-Drypetes" forest, grading into mixed Podocarpus latifolius forest on the higher elevations. To the east are "JuniperusNuxiaPodocarpus falcatus" forest, particularly on south facing slopes. On the eastern slopes these are interspersed with Podocarpus falcatus forest, much disturbed by human activities. sizeable remnants of "JuniperusRapaneaHagenia" forest can be found in the high valleys. In some of the stream valleys tree ferns such as Cyathea manniana can be found as well as small patches of the bamboo Yushania alpina.[2]

The Cherangani Hills Forest is threatened by increased pressures from a growing local population, as well as by pressure from downstream inhabitants. The problems range from overgrazing, to conversion of the forest to cropland, to excessive use of forest products in making charcoal and providing local lumber.[13][14]
