Habitat loss, disease and climate change are thought to be responsible for the drastic decline in populations in recent years. [12] Declines have been particularly intense in the western United States, Central America, South America, eastern Australia and Fiji (although cases of amphibian extinctions have appeared worldwide). While human ...
A population that was once in the tens of thousands was down to a mere 3,000. [13] The largest known chorusing groups persist in Bastrop County, but the choruses monitored in Bastrop State Park showed a dramatic decline during the mid-1990s, with little recovery of those numbers since then.

[1] The IUCN has classified each of these species into one of three conservation statuses : vulnerable VU , endangered EN , and critically endangered CR .
As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [2] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention ...
