Amphibian species (IUCN, 2015.4)
  • 6460 species have been evaluated
  • 4856 are fully assessed (excludes DD)
  • 2827 are not threatened at present (LC, NT)
  • 1994 are threatened (CR, EN, VU)

Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild.

As of February 2016, the International Union for Conservation of Nature (IUCN) lists 656 vulnerable amphibian species.[1] 10% of all evaluated amphibian species are listed as vulnerable. No subpopulations of amphibians have been evaluated by the IUCN.

For a species to be assessed as vulnerable to extinction, the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild". Endangered and critically endangered species face an even higher risk, and are listed separately even though they also meet the quantitative criteria for vulnerable species: List of endangered amphibians, List of critically endangered amphibians. The three categories combined are referred to as threatened species.

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]
