The Green Status or Species Recovery Category is expressed in words in the second version of the Green Status Assessment. It is based on the Green Score, also known as the Species Recovery Score, which is a point estimate (SRS best), with a corresponding confidence interval (bounded by SRS max and SRS min).
The Green Status focuses on recovery of populations to their original roles, and is complementary to the avoidance of species extinction measured by Red Status. Grace's research involves measures to objectively assess these outcomes across different world habitats.
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. [1] As of 2021, of the 120,372 species currently tracked by the IUCN, there are 8,404 species that are considered to be critically ...
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
Species in Chromista (IUCN, 2021-2) 15 extant species have been evaluated; 6 of those are fully assessed [a] 0 are not threatened at present [b] 6 to 15 are threatened [c] 0 to 4 are extinct or extinct in the wild: 0 extinct (EX) species; 0 extinct in the wild (EW) 4 possibly extinct [CR(PE)] 0 possibly extinct in the wild [CR(PEW)]
Using the 2001 (v3.1) system these taxa are classed as near threatened, but those that have not been re-evaluated remain with the "conservation dependent" category. This is a complete list of conservation dependent species and subspecies evaluated by the IUCN. Species and subspecies which have conservation dependent subpopulations are also ...
A Regional Red List may be created by any country or organisation by following the clear, repeatable protocol. The process is as follows: All information relevant to a species conservation status is collected, including species distribution, population trend information, habitat, ecology and life history information, threats to the species and conservation measures currently in place.
