IUCN Red List of Threatened Species
International Union for Conservation of Nature (IUCN) was founded in 1948 as world’s first global environmental organization and is the largest professional global conservation network. Over four decades ago, the Red List started as the IUCN Red Data Book and is currently compiled through the IUCN Species Programme working with the IUCN Species Survival Commission (SSC). “IUCN Red List of Threatened Species™ provides taxonomic, conservation status and distribution information on plants and animals that have been globally evaluated using the IUCN Red List Categories and Criteria. This system is designed to determine the relative risk of extinction, and the main purpose of the IUCN Red List is to catalog and highlight those plants and animals that are facing a higher risk of global extinction (i.e. those listed as Critically Endangered, Endangered and Vulnerable).” “IUCN Red List also includes information on plants and animals that are categorized as Extinct.
