The Amargosa toad (Anaxyrus nelsoni) is a species of

IUCN as being "Critically endangered".[1]

Etymology

The specific name nelsoni honors Edward William Nelson, an American naturalist and ethnologist.[4]

Distribution and habitat

The Amargosa toad is

cattails and breeding takes place in the springs where there is often little aquatic vegetation.[1]

Status

The International Union for Conservation of Nature has assessed the status of the Amargosa toad as being "critically endangered". Factors that adversely affect it include variable amounts of rainfall, the increased use of off-road vehicles, the trampling of grazing animals, dredging operations for flood control and commercial development. Another threat is the introduction of non-native species that prey on it including catfish, crayfish and bullfrogs. The population of the toads is believed to be in decline.[1]

Effective steps are being taken by local citizens, ranchers, and farmers to preserve and restore the Amargosa toad's population in the area, in part to avoid federal intervention through the

Endangered Species Act.[5]
