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.
An endangered species is a species of organisms, either flora or fauna, which face a very high risk of extinction in a proximate time frame, much sooner than the long-term horizon in which species typically persist. There are many species of birds, mammals, reptiles, amphibians and plants that live in the Mediterranean California chaparral and ...
Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. As of September 2021, the International Union for Conservation of Nature (IUCN) lists 1085 endangered amphibian species. [1] Of all evaluated amphibian species, 14% are listed as endangered. No subpopulations of amphibians have been evaluated by the ...
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.
Critically endangered (CR) species face an extremely high risk of extinction in the wild. 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 ...
The wildlife refuge was established to protect the breeding habitat for the endangered California least tern and the threatened Western snowy plover.The refuge also provides Coastal sage scrub habitat for other endangered species, including the California tiger salamander (recently listed for protection under the Endangered Species Act), California red-legged frog, Morro blue butterfly, IUCN ...
Habitat loss is perhaps the greatest threat to organisms and biodiversity. [40] Temple (1986) found that 82% of endangered bird species were significantly threatened by habitat loss. Most amphibian species are also threatened by native habitat loss, [41] and some species are now only breeding in modified habitat. [42]
The arroyo toad (Anaxyrus californicus) is a species of true toads in the family Bufonidae, endemic to California, U.S. and Baja California state, Mexico. [1] [2] It is currently classified as an Endangered species on the IUCN Red List of Threatened Species because of habitat destruction. [1]
