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.9.2% of all evaluated amphibian species are listed as critically endangered. No subpopulations of amphibians have been evaluated by the IUCN.
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.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."
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.

As of 19 August 2018, the IUCN Red List of Threatened Species has identified 3,005 critically endangered species, subspecies, stocks and subpopulations in the Animalia kingdom.
As of March 2015, the IUCN Red List of Threatened Species identified 6087 data deficient species in the Chordata phylum.

The Northwestern Andean montane forests (NT0145) is an ecoregion on the Andes mountains in the west of Colombia and Ecuador. Both flora and fauna are highly diverse due to effect of ice ages when the warmer climate zones were separated and the cooler ones combined, and interglacial periods when the reverse occurred. Because the environment is hospitable to humans, the habitat has been drastically modified by farming and grazing since the Pre-Columbian era.
The Magdalena Valley montane forests (NT0136) is an ecoregion in the Andes mountains of central Colombia.
The Eastern Cordillera Real montane forests (NT0121) is an ecoregion in the eastern range of the Andes of southern Colombia, Ecuador and northern Peru. The ecoregion covers the eastern slopes of the Andes, and includes montane forest that rises from the Amazonian rain forest, with cloud forest and elfin forest at higher elevations. It is rich in species, including many endemics. It is threatened by logging and conversion for pasturage and subsistence agriculture.
