Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-12-03
Assessor(s): Enrique La Marca, Luis A. Coloma, Santiago Ron, Claudia Azevedo-Ramos, Débora Silvano, Jerry Hardy
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 broad range of habitats, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.

Habitat and Ecology [top]

Habitat and Ecology:It is a terrestrial species found in areas of open vegetation, such as stream and river edges and agricultural clearings. It is generally associated with primary and secondary forest, forest edges and in some places savannah (eg. Trinidad). De la Riva (1993) indicated that the species has been found in human clearings, and within secondary forest in Bolivia. In Trinidad, it has been reported from roadside marshes and in vegetation close to ditches. Generally, the species lays eggs on land and has a direct development breeding strategy.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): There are no threats to the overall survival of the species.

Conservation Actions [top]

Conservation Actions: It is present in numerous protected areas.
