The IUCN Red List, established in 1964, is the most comprehensive source on the extinction risk status of species globally.
The Red List assesses the conservation status of animal, fungus, and plant species, aiming to influence policy and decision-making.
As of 2023, the Red List has surveyed 150,388 species, with 42,108 at risk of extinction.

The IUCN aims to reevaluate each species' conservation status every 5 to 10 years through the IUCN Species Survival Commission Specialist Groups.
The Red List categorizes species into 9 groups, including Extinct, Critically Endangered, Vulnerable, and Least Concern.
Categories are based on criteria like population decline, size, geographic distribution, and potential future threats.
Species are assessed using 5 criteria: geographic range, population size, population trend, and extinction probability analyses.
Some species previously listed as Extinct have been reclassified after being rediscovered, known as "Lazarus" species.
