List of endangered amphibians
- Extinct, since 1500: 33 species
- Extinct in the wild (EW): 2 species
- Critically endangered (CR): 528 species
- Endangered (EN): 810 species
- Vulnerable (VU): 656 species
- Near threatened (NT): 400 species
- Least concern (LC): 2,427 species
- Data deficient (DD): 1,604 species
As of February 2016, the International Union for Conservation of Nature (IUCN) lists 810 endangered amphibian species.[1] 13% of all evaluated amphibian species are listed as endangered. No subpopulations of amphibians have been evaluated by the IUCN.
For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by critically endangered species, which are listed separately (List of critically endangered amphibians) even though they also meet the quantitative criteria for endangered species. There are 1338 amphibian species which are endangered or critically endangered.
Additionally 1604 amphibian species (25% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN.[2] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."[3]
This is a complete list of endangered amphibian species and subspecies as evaluated by the IUCN. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.
