Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups within the IUCN Species Survival Commission(SSC). Collectively, assessments by these organizations and groups account for nearly half the species on the Red List.

Species are classified by the IUCN Red List into nine groups

Extinct (EX) – No known individuals remaining.

Extinct in the wild (EW) – Known only to survive in captivity, or as a naturalized population outside its historic range.

Critically endangered (CR) – Extremely high risk of extinction in the wild.

Endangered (EN) – High risk of extinction in the wild.

Vulnerable (VU) – High risk of endangerment in the wild.

Near threatened (NT) – Likely to become endangered in the near future.

Least concern (LC) – Lowest risk.Does not qualify for a more at-risk category. Widespread and abundant taxa are included in this category.

Data deficient (DD) – Not enough data to make an assessment of its risk of extinction.

Not evaluated (NE) – Has not yet been evaluated against the criteria.
