Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-12-29
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 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.
Previously published Red List assessments:
2008 Least Concern (LC)
2004 Least Concern (LC)

Geographic Range [top]

Range Description: This species geographic range is from the humid forests of lowland and premontane zones and lower portion of the lower montane zone from northern Costa Rica to western Panama (40-1,800m asl). There are no records of this species from Colombia although it has been cited as occurring there in some literature.
Countries occurrence:
Costa Rica; Panama
Lower elevation limit (metres): 40
Upper elevation limit (metres): 1800

Population [top]

Population: While there might be more than one biological species classified in this taxon, with the exception of La Selva (Whitfield et al., 2007), there are no signs of decline anywhere in the Costa Rica range (Lips, 1998; Andrew R. Gray in litt. to Karen Lips, 2007 [report on continued presence at Las Tablas]). There is no information on the populations of this species in Panama.
Current Population Trend: Stable
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: This species inhabits most forest types including humid lowland and montane forest. It is also found in degraded habitats outside forest. Adults are generally found on low vegetation. It is direct-developing species, and the eggs may be laid in the crevices of tree trunks.
Systems: Terrestrial

Threats [top]

Major Threat(s): General habitat loss by the destruction of natural forests is a threat. While museum specimens of this species have been found to have the chytrid fungus, the current impact of this pathogen on the species is not known. At La Selva, declines seem to be driven by climate-driven reductions in quantity of standing leaf litter (Whitfield et al., 2007).

Conservation Actions [top]

Conservation Actions: While there are no specific conservation measures in place, the species has been recorded from many protected areas.
