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)
