List of critically endangered amphibians
From Wikipedia, the free encyclopedia
As of December 2021, the International Union for Conservation of Nature (IUCN) lists 673 critically endangered amphibian species, including 146 which are tagged as possibly extinct.[1][2] 9.2% of all evaluated amphibian species are listed as critically endangered. No subpopulations of amphibians have been evaluated by the IUCN.
- Extinct in the wild (EW): 2 species
- Critically endangered (CR): 545 species
- Endangered (EN): 848 species
- Vulnerable (VU): 670 species
- Near threatened (NT): 402 species
- Least concern (LC): 2,458 species
- Data deficient (DD): 1,567 species
Additionally, 1193 amphibian species (16.4% 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.[3] 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."[4]
This is a complete list of critically endangered amphibian species evaluated by the IUCN. Species considered possibly extinct by the IUCN are marked as such.
