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)
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]
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.

The 2008 Red List was released on 6 October 2008 at the IUCN World Conservation Congress in Barcelona and "confirmed an extinction crisis, with almost one in four [mammals] at risk of disappearing forever". The study shows at least 1,141 of the 5,487 mammals on Earth are known to be threatened with extinction, and 836 are listed as Data Deficient.
