The IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List), founded in 1963, is the world's most comprehensive inventory of the global conservation status of biological species.The International Union for Conservation of Nature (IUCN) is the world's main authority on the conservation status of species. The Red List process has become a massive enterprise involving the IUCN Global Species Program staff, partner organisations and experts in the IUCN Species Survival Commission and partner networks who compile the species information to make The IUCN Red List the indispensable product it is today. International Union for Conservation of Nature, The Official Site of IUCN Red List of Threatened Species. The IUCN system uses a set of five quantitative criteria to assess the extinction risk of a given species. Each year thousands of scientists around the world assess or reassess species.
The IUCN Red List of Threatened Species™ is used to guide decision making and conservation action. The IUCN Red List is used by government agencies, wildlife departments, conservation-related non-governmental organisations (NGOs), natural resource planners, educational organisations, students, and the business community. The IUCN Red List of Threatened Species.

Ultimately, The IUCN Red List helps to guide and inform future conservation and funding priorities.
Whether the species already possesses a small population size, Whether the species is very small or lives in a restricted area, Extinct in the Wild (EW), a category containing those species whose members survive only in captivity or as artificially supported populations far outside their historical geographic range, Critically Endangered (CR), a category containing those species that possess an extremely high risk of extinction as a result of rapid population declines of 80 to more than 90 percent over the previous 10 years (or three generations), a current population size of fewer than 50 individuals, or other factors, Endangered (EN), a designation applied to species that possess a very high risk of extinction as a result of rapid population declines of 50 to more than 70 percent over the previous 10 years (or three generations), a current population size of fewer than 250 individuals, or other factors, Near Threatened (NT), a designation applied to species that are close to becoming threatened or may meet the criteria for threatened status in the near future, Least Concern (LC), a category containing species that are, Data Deficient (DD), a condition applied to species in which the amount of available data related to its risk of extinction is lacking in some way. By 2019, 96,500 species had been assessed by using the IUCN Red List categories and criteria. Currently, there are more than 120,000 species on The IUCN Red List, with more than 32,000 species threatened with extinction, including 41% of amphibians, 34% of conifers, 33% of reef building corals, 26% of mammals and 14% of birds. The IUCN Red List brings into focus the ongoing decline of Earth’s biodiversity and the influence humans have on life on the planet. Thus, unlike the other categories in this list, this category does not describe the conservation status of a species, Not Evaluated (NE), a category used to include any of the nearly 1.9 million species described by. In addition, a number of areas rich in unique species that…. As a result, interested parties, such as national governments and conservation organizations, may use the information provided in the IUCN Red List to prioritize their own species-protection efforts.
Nevertheless, on July 9 the IUCN released its latest Red List of Threatened Species, covering the changing fates of some of the 120,000 species it monitors.
The IUCN Red List is subsequently updated with these new data once the assessments have been checked for accuracy. The IUCN Red List is a critical indicator of the health of the world’s biodiversity.

One of the most well-known objective assessment systems for declining species is the approach unveiled by the International Union for Conservation of Nature (IUCN) in 1994. In addition, three of the categories (CR, EN, and VU) are contained within the broader notion of “threatened.” The IUCN Red List of Threatened Species recognizes several categories of species status: All else being equal, a species experiencing an 90 percent decline over 10 years (or three generations), for example, would be classified as critically endangered. On 13 April 2020 the IUCN Species Survival Commission Bat Specialist Group recommended the suspension of all field work that involves interactions with bats while it considered the risk of human-bat transmission of SARS-CoV-2.

improvement) of a number of species on the IUCN Red List categories scale, due to conservation efforts. Consequently, a complete assessment cannot be performed. IUCN today launched a global standard for classifying the severity and type of impacts caused by alien species, known as the Environmental Impact Classification for Alien Taxa (EICAT). The International Union for Conservation of Nature (IUCN) Red List of Threatened Species (also known as the IUCN Red List or Red Data List), founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species.It uses a set of criteria to evaluate the extinction risk of thousands of species and subspecies. In this way, the information helps to provide a continual spotlight on the status of the world’s at-risk plants, animals, and other organisms.
