Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2008-01-01
Assessor/s: Frank Solís, Roberto Ibáñez, Gerardo Chaves, Jay Savage, César Jaramillo, Querube Fuenmayor, Federico Bolaños
Reviewer/s: Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it is relatively common with a presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description: This species is known from the humid lowland and premontane zones of southwestern Costa Rica and adjacent southwestern Panama, at elevations of 10-1,220m asl (Savage, 2002).

Population [top]

Population: It is a common species that is regularly seen in Costa Rica. It is not very abundant from the Río Terraba to Río Savagre along the Pacific slope of Costa Rica, and appears to be one of the least common frogs in this region.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It is a large, nocturnal, terrestrial species of primary humid lowland forest, secondary forest, and plantations. It breeds by direct development and the eggs are probably deposited in leaf-litter. Juveniles may be found active during the night and day. Juveniles have been seen mainly in the mid to late wet season (Savage, 2002, M. Ryan pers. comm.).
Systems: Terrestrial

Threats [top]

Major Threat(s): It is generally threatened by habitat loss resulting from deforestation. In five years of surveys it was not found to occur in forest patches less than 10ha in size (M. Ryan pers. comm.).

Conservation Actions [top]

Conservation Actions: Although there are no specific conservation measures in place, the species has been recorded from a number of protected areas in Costa Rica. Further research is needed into the range, ecology, and potential conservation measures for this frog.
