The world's most comprehensive inventory assessing the conservation status of plant and animal species.
Detailed Explanation
The IUCN Red List uses quantitative criteria — population size, rate of decline, range size, and extinction probability models — to assign species to nine categories from Least Concern to Extinct. Over 44,000 of the 157,000+ assessed species are threatened. Red List assessments inform national legislation, CITES listings, and conservation funding priorities. Reassessments every 5-10 years track whether populations are recovering or declining.
