The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
Extinct in the Wild (EW): captive individuals survive, and/or the species has been reintroduced outside its former natural range, but the species otherwise matches the criteria for "Extinct", such that no free-living, natural population is believed to exist. "Extirpated" is a term used for localized extinctions of extant species; it always ...
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. [1]
The majority of the species were considered endangered in the 1970s and 1980s when they “were in very low numbers or likely already extinct at the time of listing,” the release said.
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 endangered in the near future.
This Act has six categories: extinct, extinct in the wild, critically endangered, endangered, vulnerable, and conservation dependent, as defined in Section 179 of the Act. [3] These could be summarised as: [4] "Extinct" – "no reasonable doubt that the last member of the species has died";
The species recovery score is a 0%–100% scale, with 0% being the species is extinct or extinct in the wild and 100% being fully recovered. [40] In addition, the Green Status also classifies previous and future conservation impacts with the Green Scores of Conservation Dependency, Conservation Gain, Conservation Legacy, and Recovery Potential.
The Red List of Endangered Crafts was created in 2017 by the national charity for traditional heritage crafts - Heritage Crafts. Crafts are ranked from viable through endangered to extinct.
