A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species ...

In 1997, the IUCN Red List received criticism on the grounds of secrecy (or at least poor documentation) surrounding the sources of its data. [31] These allegations have led to efforts by the IUCN to improve its documentation and data quality, and to include peer reviews of taxa on the Red List. [ 24 ]
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
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 1851 near threatened plant species. [1] 8.5% of all evaluated plant species are listed as near threatened. The IUCN also lists 51 subspecies and 73 varieties as near threatened. No subpopulations of plants have been evaluated by the IUCN.
The IUCN also lists 244 subspecies and 235 varieties as Vulnerable. No subpopulations of plants have been evaluated by the IUCN. For a species to be assessed as vulnerable to extinction the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild".
On 12 March 2010, the IUCN Red List of Threatened Species identified 3829 (2657 Animalia, 1172 Plantae) near threatened species, subspecies and varieties, stocks and sub-populations.
