It provides information about species’ range, population size, habitats and ecology, use and trade, threats, and conservation actions that help inform conservation decisions.Species are classified into one of nine Red List Categories: Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern, Data Deficient and Not Evaluated. Vulnerable, Endangered and Critically Endangered species are considered to be threatened with extinction.

      The IUCN Red List will be updated with thousands of new species assessments and reassessments on Monday 11 December 2023.
