Species are classified by the IUCN Red List into nine groups:

Extinct (EX) – beyond reasonable doubt that the species is no longer extant.

Extinct in the wild (EW) – survives only in captivity, cultivation and/or outside native range, as presumed after exhaustive surveys.

Critically endangered (CR) – in a particularly and extremely critical state.

Endangered (EN) – very high risk of extinction in the wild, meets any of criteria A to E for Endangered.

Vulnerable (VU) – meets one of the 5 red list criteria and thus considered to be at high risk of unnatural (human-caused) extinction without further human intervention.

Near threatened (NT) – close to being at high risk of extinction in the near future.

Least concern (LC) – unlikely to become extinct in the near future.

Data deficient (DD)

Not evaluated (NE)
