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

As of September 2016, the International Union for Conservation of Nature (IUCN) lists 670 vulnerable amphibian species. [1] 10% of all evaluated amphibian species are listed as vulnerable. No subpopulations of amphibians have been evaluated by the IUCN.

Contents

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 also meet the quantitative criteria of vulnerable species, and are listed separately. See: List of endangered amphibians, List of critically endangered amphibians. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN.

Additionally 1567 amphibian species (24% 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]

Franz Werner

Franz Josef Maria Werner was an Austrian zoologist and explorer. Specializing as a herpetologist and entomologist, Werner described numerous species and other taxa of frogs, snakes, insects, and other organisms.

In August 2018, the IUCN Red List of Threatened Species identified 6086 Vulnerable species, subspecies and varieties, stocks and sub-populations in the Animalia kingdom.

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.

IUCN Red List endangered species (Animalia)

On 19 August 2018, the IUCN Red List of Threatened Species identified 4584 endangered species, subspecies, stocks and subpopulations.

On 29 January 2010, the IUCN Red List of Threatened Species identified 2657 near threatened species, subspecies, stocks and sub-populations in the Animalia kingdom.

Eastern Cordillera Real montane forests

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.
