IUCN Red List
The global assessment of how close each species is to extinction, published by the International Union for Conservation of Nature.
Each assessed species is placed in a category, from Least Concern to Extinct, using published criteria on population size, rate of decline and range.
This site shows the category as recorded on Wikidata and links to the Red List for the assessment itself. A species with no category shown has not been matched to an assessment; that is not a statement that it is safe.
