Although some species, such as the rough-skinned newt (Taricha granulosa) and Eastern newt (Notophthalmus viridescens) in North America or the smooth newt (Lissotriton vulgaris) in Europe, are still relatively common, populations of newts throughout their distribution range suffer from habitat loss, fragmentation, and pollution. This affects ...
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 .
These animals are common aquarium pets, being either collected from the wild or sold commercially. The striking bright orange juvenile stage, which is land-dwelling, is known as a red eft. Some sources blend the general name of the species and that of the red-spotted newt subspecies into the eastern red-spotted newt (although there is no ...

Four species are categorized as endangered by the International Union for Conservation of Nature: the Barton Springs salamander, the Texas blind salamander, the black-spotted newt, and the Houston ...
Palmate newt populations are not in decline overall, and the species has been assessed as Least Concern by the IUCN. [1] In France, it is the most common newt species, [10] but it is rare in Belgium and the Netherlands, [4]: 225 and populations are fragmented on the Iberian peninsula. [1] It is included in some national and regional red lists. [1]
This is a checklist of amphibians found in Northern America, based mainly on publications by the Society for the Study of Amphibians and Reptiles. [1] [2] [3] The information about range and status of almost all of these species can be found also for example in the IUCN Red List of Threatened Species site. [4]
The other two species are in fact threatened, with P. nebulosus considered vulnerable to extinction and P. poireti classified as an endangered species. [2] The numbers of all three species are declining in the wild. Livestock agriculture is an ongoing major cause of habitat loss and degradation, and of water pollution, for all three species.
