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]
South Africa has a wide range of marine diversity with coastline in three oceans, two major current systems, major ocean frontal systems and benthic topography extending to a maximum depth of 5 700 m. There are 179 defined marine ecosystem types, 150 of them around South Africa and 29 around the sub-Antarctic territory of the Prince Edward Islands.
This listing contains taxa of plants in the division Bryophyta, recorded from South Africa.Mosses, or the taxonomic division Bryophyta, are small, non-vascular flowerless plants that typically form dense green clumps or mats, often in damp or shady locations.
This list of Ramsar sites in South Africa are wetland environs that are considered to be of international importance, and protected under the Ramsar Convention. As of 2024, South Africa has 30 such sites covering 574 028 hectares. [1] [2] For a complete list of all Ramsar sites worldwide, see the List of Ramsar wetlands of international importance.
This is a list of Southern African trees, shrubs, suffrutices, geoxyles and lianes, and is intended to cover Angola, Botswana, Eswatini, Lesotho, Malawi, Mozambique, Namibia, South Africa, Zambia and Zimbabwe. [1] The notion of 'indigenous' is of necessity a blurred concept, and is clearly a function of both time and political boundaries.
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.
