Red List of Ecosystems (RLE) for terrestrial realm for South Africa - remnants

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 are 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). Ecosystems 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).

Purpose

The list of threatened terrestrial ecosystems is an important input into spatial planning and decision making in South Africa. The list and the spatial data underpinning it is referred to in national regulations relating to environmental impact assessment (EIA); specifically – Critically Endangered and Endangered ecosystem types trigger additional steps and processes during environmental authorisation processes. The data will also become part of the Environmental Screening Tool developed by the Department of Forestry Fisheries and the Environment which all prospective developers are required to complete prior to the environmental authorisation process. The remnants of the threatened types are input features in systematic biodiversity plans and are mostly absorbed as part of the Critical Biodiversity Areas network.

Statement

The List of terrestrial ecosystems that are threatened or in need of protection that was gazetted in 2011 represents the first version of the dataset, using slightly different methods and input data from 2000 and 2006. Work on this version of the Red List of Ecosystems started in 2016 as part of the National Biodiversity Assessment, and a preliminary output was published in 2019 as part of the NBA. In 2020 further updates were applied and review comments by conservation authorities were incorporated. This version was approved for public comment (by the national Department of Forestry Fisheries and the Environment and the Provincial departments of environment) in June 2021.
