|Scientific Name:||Acris crepitans Baird, 1854|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Geoffrey Hammerson, Georgina Santos-Barrera, Don Church|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)|
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
|Range Description:||This species is known from southeastern New York, the southern Great Lakes region, and southern South Dakota to southeastern New Mexico, southern Texas, USA, and adjacent Mexico, and the Gulf Coast east to northwestern Florida. Isolated populations occur on the Coastal Plain of South Carolina. In Canada, it is restricted to Point Pelee (formerly) and Pelee Island in extreme southwestern Ontario (Oldham and Campbell, 1990 COSEWIC report).|
Native:Canada; Mexico; United States

|Population:||This species is common throughout most of its extensive range, although there have been some declines in the northwestern part of its range. Also, in the eastern portion of its range, populations are disappearing from agricultural and grazed areas in the Shendoah Valley of Virginia.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This species inhabits the edges of sunny marshes, marshy ponds, and small slow-moving streams in open country and in forest along bodies of water without dense canopy cover. It may periodically range into adjacent non-wetland habitats in some regions. Eggs and larvae develop in the shallow water of ponds, marshes, ditches, slow streams, springs, or rain pools.|
|Major Threat(s):||It appears to be significantly threatened only in the northwestern portion of its range. The reasons for the declines remain speculative but vegetation succession, climatic fluctuations, predation by native and exotic species, competition from other frog species, and water pollution caused by pesticides and/or other chemicals associated with agriculture are possibly significant (Harding 1997, Lannoo 1998, Hammerson 1999, Hammerson and Livo 1999).|
