The conservation status o a group o organisms (for instance, a species) indicates whether the group is extant (members o it are still alive) an hou likely the group is tae acome extinct in the near futur. Mony factors are taken intae accoont when assessin conservation status: nae simply the nummer o individuals remainin, but the oweraw increase or decrease in the population ower time, breedin success rates, kent threats.
The IUCN Red Leet of Threatened Species is the best-kent warldwide conservation status leetin an rankin seestem. Species are classified bi the IUCN Red List intae nine groups set through criteria such as rate o decline, population size, aurie o geografic distribution, an degree o population an distribution fragmentation. An aa includit are species that hae gone extinct syne 500 AD. When discussin the IUCN Red List, the offeecial term "threatened" is a groupin o three categories: Critically Endangered, Endangered, an Vulnerable.
- Extinct (EX) – Na kent individuals remainin.
- Extinct in the Wild (EW) – Kent anly tae survive in captivity, or as a naituralized population ootside historic range.
- Critically Endangered (CR) – Extremely high risk o extinction in the wild.
- Endangered (EN) – Heich risk o extinction in the wild.
- Vulnerable (VU) – Heich risk o endangerment in the wild.
- Near Threatened (NT) – Likely tae acome endangered in the near futur.
- Least Concern (LC) – Lawest risk. Daes nae qualify for a heicher risk category. Widespread an abundant taxa are includit in this category.
- Data Deficient (DD) – Nae enough data tae mak an assessment o its risk o extinction.
- Nae Evaluatit (NE) – Haes nae yet been evaluatit against the criteria.
The Convention on Internaitional Trade in Endangered Species o Wild Fauna an Flora (CITES) aims tae ensure that internaitional trade in specimens o wild animals an plants daes nae threaten thair survival. Mony kintras require CITES permits when importin plants an animals leetit on CITES.
