How many species are threatened? Species assessed as Critically Endangered (CR), Endangered (EN), or Vulnerable (VU) are referred to as "threatened" species. However, Extinct in the Wild (EW) species can move into the threatened categories following successful reintroduction.
Our current goals, based on the IUCN Red List Strategic Plan (2021-2030), are to have 260,000 species assessed and to reassess 142,000 of those species to ensure the information on their status is up-to-date so that we can monitor trends in change of status.

There are over 1,300 species listed as either endangered or threatened in the United States under the Endangered Species Act. The Fish and Wildlife Service, in the Department of the Interior, and NOAA's National Marine Fisheries Service, in the Department of Commerce, share responsibility for administering the ESA.
Key insights on Biodiversity. On average, there has been a large decline across tens of thousands of wildlife populations since 1970. Not all animal populations are in decline; around half have increasing numbers. Wild mammals have declined by 85% since the rise of humans.
The IUCN Red List of Threatened Species™ is the world’s most comprehensive information source on the global extinction risk status of animal, fungus and plant species. Open to all, it is used by governmental bodies, non-profit organisations, businesses and individuals.
The IUCN Red List has assessed the extinction risk of only a small share of the total known species in the world. This means the number of species threatened with extinction is likely to be a significant underestimate of the total number of species at risk.
Under the Endangered Species Act of 1973, as amended (ESA; 16 U.S.C. 1531 et seq.), we maintain Lists of Endangered and Threatened Wildlife and Plants (which we collectively refer to as the List) in the Code of Federal Regulations (CFR) at 50 CFR 17.11 (for animals) and 17.12 (for plants). Section 4(c)(2)(A) of the ESA requires us to review ...
Only 23% of species and 16% of its habitats are in good health; 1,677 out of 15,060 European species are threatened with extinction; most endangered are snails, clams and fish; 6 animal, bird and fish species, including the Saiga antelope, the gyrfalcon and the Persian leopard, are facing risk of extinction in Russia
