What it covers
- Geography
- World (global Red List assessments)
- Basis
- Species assessed for the IUCN Red List (global assessments); threatened = Critically Endangered, Endangered or Vulnerable. Only assessed species are counted: birds, mammals, amphibians, sharks and rays are almost fully assessed, insects, plants and fungi only in small, non-random part, so their figures describe the assessed species, not the whole group. The period is the year of the Red List version.
