Established in 1964, The International Union for Conservation of Nature’s Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
Currently, there are more than 157,100 species on The IUCN Red List, with more than 44,000 species threatened with extinction, including 41% of amphibians, 37% of sharks and rays, 36% of reef building corals, 34% of conifers, 26% of mammals and 12% of birds.
The Red List Index (RLI) shows trends in overall extinction risk for species, and is used by governments to track their progress towards targets for reducing biodiversity loss. Most species that move between categories on The IUCN Red List (see the section Reasons for Changing Category ) do so because of improved knowledge or revised taxonomy.
The IUCN Red List of Threatened Species™ is the world’s most comprehensive information source on the global extinction risk status of animal, fungus and plant species. Open to all, it is used by governmental bodies, non-profit organisations, businesses and individuals.
The Guidelines for Using the IUCN Red List Categories and Criteria are regularly updated: the current version is version 16 (March 2024). Please check that you have the most recent version before starting to prepare an assessment for publication on The IUCN Red List.
