South Africa is a sunny country, averaging 8–10 daily sunshine hours in most regions. [2] The average annual rainfall for South Africa is about 464 mm (compared to a global average of 950 mm [3]) but large and unpredictable variations are common. Overall, rainfall is greatest in the east and gradually decreases westward, with some semi-desert ...
Mapping of the distribution and extent of natural vegetation of South Africa started in 1918 when the Botanical Survey of the Union of South Africa was established. Maps by Pole-Evans (1936), Acocks (1953), and Low and Rebelo (1996) preceded the current system, which is the combined effort of participants from various centres in the country. [2]
Agulhas ecoregion – Ecoregion off the coast of South Africa; Natal ecoregion – Marine ecoregion on the eastern coast of South Africa; Delagoa ecoregion – Marine ecoregion on the eastern coast of southern Africa; Prince Edward Islands – Two small sub-Antarctic islands belonging to South Africa
The climate of the Nama Karoo tends to be volatile, unpredictable and rather harsh, with only the most specially-adapted organisms calling the region home. The annual ‘dry’ season—a time of blistering hot weather and drought—is long, often taking place over autumn and winter, and into early spring. Heavy rainfall primarily occurs in the ...
If correct, then the number of South African fungi dwarfs that of its plants. In at least some major South African ecosystems, an exceptionally high percentage of fungi are highly specific in terms of the plants with which they occur. [64] The country's Biodiversity Strategy and Action Plan does not mention fungi (including lichen-forming fungi ...
Three scenarios have been modeled for climate change impacts on the South African biomes. The low risk scenario suggests a possible increase in area for this biome, with warm, moist conditions expanding southwest along the coast, and extending further inland, but the intermediate and high risk models show a possibility of less water availability and parts of the biome shifting to a savanna ...
The ecoregion, which is South Africa's smallest in area, covers two separate enclaves. The Knysna forest extends along the coast between 22°E and 25°E, generally along 34°S in a region called the Garden Route. The KwaZulu-Cape coastal forest mosaic lies along the coast to the north-east.
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 tip of Africa – separated from the other forested areas to the east and north.
