Habitat modification or destruction is one of the most dramatic issues affecting amphibian species worldwide. As amphibians generally need aquatic and terrestrial habitats to survive, threats to either habitat can affect populations. Hence, amphibians may be more vulnerable to habitat modification than organisms that only require one habitat type.
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature.
The world’s frogs, salamanders, newts and other amphibians remain in serious trouble. A new global assessment has found that 41% of amphibian species that scientists have studied are threatened ...
Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild. In September 2016, the International Union for Conservation of Nature (IUCN) listed 670 vulnerable amphibian species. [1] Of all evaluated amphibian species, 10% are listed as vulnerable. No subpopulations of amphibians have been evaluated by the IUCN.
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.

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. [1] [2] 9.2% of all evaluated amphibian species are listed as critically endangered. No subpopulations of amphibians have been evaluated by the IUCN.

A 2013 study estimated that 670–933 amphibian species (11–15%) are both highly vulnerable to climate change while already being on the IUCN Red List of threatened species. A further 698–1,807 (11–29%) amphibian species are not currently threatened, but could become threatened in the future due to their high vulnerability to climate ...
