Description: Polygon features, representing Red List of Ecosystems (RLE) for terrestrial realm for South Africa. This dataset contains the current remaining natural extent (circa 2018) of each of the 458 ecosystem types assessed. This means that those portions of ecosystems that have been lost to anthropogenic activities such as mining or croplands excluded and only the remnants are part of the dataset. A separate dataset (RLE_Terr_2021_June2021_ddw.shp) is also available and contains the historical / potential extent of each ecosystem type. This RLE is a revision of the “List of terrestrial ecosystems that threatened or in need of protection” published in the government gazette in December 2011. The revision is based on the best available data and used the IUCN RLE risk assessment framework version 1.1 (Bland et al. 2017). Ecosystem are categorised into one of four classes representing their risk of collapse; in descending order of risk: Critically Endangered, Endangered, Vulnerable, Least Concern. The national vegetation map, 2018 version (Mucina and Rutherford 2006; Dayaram et al., 2019) provided the ecosystem units of assessment for the RLE (Vegetation Unit / Type level).
