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]

The Red List of South African Plants is a system used to classify endemic species of plants in South Africa that are at risk of extinction. The South African National Biodiversity Institute (SANBI) designates the conservation status of endemic species according to the IUCN Red List system of categories and criteria.
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
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 ...
