Additionally 1193 amphibian species (16% 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]
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]
The distribution of 2,873 globally threatened amphibian species. [2] In the past three decades, declines in populations of amphibians (the class of organisms that includes frogs, toads, salamanders, newts, and caecilians) have occurred worldwide. In 2004, the results were published of the first worldwide assessment of amphibian populations, the ...
Researchers evaluated the health of more than 8,000 amphibian species around the world and determined that nearly 41% — 2,871 in total — are globally threatened.
Version 2014.2 of the IUCN Red List of Threatened Species identified 4574 critically endangered species, subspecies, varieties, stocks, and subpopulations. For IUCN lists of critically endangered species by kingdom, see: Animals (kingdom Animalia) — IUCN Red List critically endangered species (Animalia)
As of July 2021, the IUCN lists 14,033 animal species and 6,635 plant species as least concern. [1] No least concern assessments have been made for taxa of other kingdoms. ...
According to the International Union for Conservation of Nature (IUCN), 93 reptile and amphibian species in the United States are threatened with extinction. [1] The IUCN has classified each of these species into one of three conservation statuses: vulnerable VU, endangered EN, and critically endangered CR.
[1] 16% of all evaluated amphibian species are listed as data deficient. No subpopulations of amphibians have been evaluated by the IUCN. This is a complete list of data deficient 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.
