The World's 100 most threatened species [1] is a compilation of the most threatened animals, plants, and fungi in the world. It was the result of a collaboration between over 8,000 scientists from the International Union for Conservation of Nature Species Survival Commission (IUCN SSC), along with the Zoological Society of London .

Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. In September 2016, the International Union for Conservation of Nature (IUCN) listed 3654 endangered plant species. [1] Of all evaluated plant species, 17% are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered.
There are also 101 animal subspecies listed and 1500 plant taxa (1410 species, 55 subspecies, and 35 varieties). No fungi or protista have the classification, though only four species in those kingdoms have been evaluated by the IUCN. Humans were formally assessed [3] as a species of least concern in 2008.
As of July 2021, the IUCN lists 14,033 animal species and 6,635 plant species as least concern. [1] No least concern assessments have been made for taxa of other kingdoms. Lists: Animals (kingdom Animalia) Amphibians — List of least concern amphibians; Birds — List of least concern birds; Fish — List of least concern fishes
See: List of endangered plants, List of critically endangered plants. Vulnerable, Endangered, and Critically Endangered species are collectively referred to as threatened species by the IUCN. Additionally 1674 plant species (7.6% of those evaluated) are listed as Data Deficient, meaning there is insufficient information for a full
[1] 30% of all evaluated plant species are listed as least concern. The IUCN also lists 131 subspecies and 118 varieties as least concern. No subpopulations of plants have been evaluated by the IUCN. This is a complete list of least concern plant species, subspecies and varieties evaluated by the IUCN.
The Red List of 2012 was released 19 July 2012 at Rio+20 Earth Summit; [17] nearly 2,000 species were added, [18] with 4 species to the extinct list, 2 to the rediscovered list. [19] The IUCN assessed a total of 63,837 species which revealed 19,817 are threatened with extinction.
[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. This is a complete list of near threatened plant species, subspecies and varieties evaluated by the IUCN.
