South Africa- Goal A

National data:

Indicator outputs were produced and provided by the country/territory. Therefore, values may differ from the ones displayed at the Nationally disaggregated from global sources tab.

Goal A The integrity, connectivity and resilience of all ecosystems are maintained, enhanced, or restored, substantially increasing the area of natural ecosystems by 2050; Human induced extinction of known threatened species is halted, and, by 2050, extinction rate and risk of all species are reduced tenfold and the abundance of native wild species is increased to healthy and resilient levels; The genetic diversity within populations of wild and domesticated species, is maintained, safeguarding their adaptive potential.

Headline Indicators

A.1 Red List of Ecosystems Indicator definition: The Red List of Ecosystems framework assesses the relative risk of ecosystem collapse of an ecosystem type. The indicator 'Red List Index of Ecosystems (RLIe)' measures the average risk of ecosystem collapse of a group of ecosystems and allows for tracking change over time, based on genuine change in the risk category of each ecosystem. The RLIe can be calculated for any...

A.2 Extent of natural ecosystems The concepts, definitions and classification used have been based on the System of Environmental-Economic Accounting (SEEA) Ecosystem Accounting. The SEEA Ecosystem Type Reference Classification based on the International Union for the Conservation of Nature Global Ecosystem Typology (IUCN GET) forms the classification basis for this indicator. The three upper levels of IUCN GET - realms,...

A.3 Red List Index Definition: The Red List Index measures change in aggregate extinction risk across groups of species. It is based on genuine changes in the number of species in each category of extinction risk on The IUCN Red List of Threatened Species (www.iucnredlist.org) and is expressed as changes in an index ranging from 0 to 1. Concepts: Threatened species are those listed on The IUCN Red List of...

A.4 The proportion of populations within species with an effective population size > 500 The indicator definition is exemplified in the full name, "The proportion of populations within species with a genetically effective population size > 500."The indicator should be reported for 100+ representative species per country.It is calculated by taking each population of a species, determining if each population is above the threshold of Ne 500, calculating a proportion of populations...
