IUCN Red List Conservation Status Categories - TSV
The IUCN Red List is an international standard established by the International Union for Conservation of Nature (IUCN) in 1994 for objectively assessing the extinction risk of species on Earth. It classifies the conservation status of species into nine categories (Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern, Data Deficient, and Not Evaluated). Based on quantitative assessment criteria, it is widely used for conservation activities and policy decisions worldwide.
