Assessment Information

Red List Category & Criteria:	LC ver 3.1 (2001)
Year Assessed:	2004
Assessor/s:	Hammerson, G. & Hedges, B.
Evaluator/s:	Stuart, S., Chanson, J., Cox, N. & Young, B. (Global Amphibian Assessment Coordinating Team)
Justification:	Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range

Range Description:

This species occurs in the USA, from Delaware south to southern Florida along Coastal Plain, west to south-central Texas; north from Gulf Coast to southeastern Oklahoma, southeastern Missouri, southern Illinois, western Kentucky, western Tennessee, and northern Alabama; isolated population in south-central Missouri (Conant and Collins 1991). This species has been introduced into extreme northwestern Puerto Rico (Isabela-Aguadilla area), but it is not clear if it still survives there.

Habitat and Ecology

Habitat and Ecology:

Swamps, marshes, and the edges of ponds, lakes, and streams, particularly where there is abundant floating and emergent vegetation. During daytime, rests among cattail blades or other leaves or shaded branches. Eggs and larvae develop in shallow, still water. Males call while perched on plants next to water (up to 5 m above surface) or while sitting on floating plants. Larvae occur mainly in dense floating vegetation.

System:

Terrestrial; Freshwater

List of Habitats:

5.4	Wetlands (inland) - Bogs, Marshes, Swamps, Fens, Peatlands
5.7	Wetlands (inland) - Permanent Freshwater Marshes/Pools (under 8ha)
5.8	Wetlands (inland) - Seasonal/Intermittent Freshwater Marshes/Pools (under 8ha)

Threats

Threats:
