Southern Afrotemperate Forest : ウィキペディア英語版 | Southern Afrotemperate Forest
Southern Afrotemperate Forest (the Southern Cape Forests) is a kind of tall, shady, multilayered indigenous South African forest. This is the main forest-type in the south-western part of South Africa, naturally extending from the Cape Peninsula in the west, as far as Port Elizabeth in the east. In this range (apart from the massive Knysna-tsitsikamma forest complex), it usually occurs in small forest pockets, surrounded by fynbos vegetation. ==Ecology== This forest ecosystem is a subtype of the general Afromontane forest, which can be found across Africa as far north as Ethiopia. However, it is distinguished from other types of forests in southern Africa by its relatively distinct range of species and its being confined to the far south-western corner of Africa – separated from the other forested areas to the east and north. Southern Afrotemperate Forest tends to grow on soils derived from sandstone and granite which are the dominant rock formations in the south-western Cape.〔A.B. Low & A.G. Rebelo (eds). Vegetation of South Africa, Lesotho & Swaziland, a companion to the vegetation map of South Africa, Lesotho and Swaziland. Dept Environmental Affairs and Tourism, Pretoria. 85pp. ISBN 0-621-17316-9.〕 The Western Cape is prone to seasonal fires and the various types of fynbos vegetation that dominate here are all governed by the fire cycles. However, Southern Afrotemperate Forest is not adapted to fire, so is always restricted to "fire refugia" such as gorges, wet riverine areas, or rocky scree slopes where fires cannot reach. In the absence of veld fires, the taller forests tend to expand at the expense of the fynbos.〔A.G. Rebelo, C. Boucher, N. Helme, L. Mucina, M.C. Rutherford et al. 2006. Fynbos Biome, in: L. Mucina & M.C. Rutherford (eds). The Vegetation of South Africa, Lesotho and Swaziland. Strelitzia 19, pp 52‐219.〕
