Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-09-30
Assessor(s): Frank Solís, Roberto Ibáñez, Gerardo Chaves, Jay Savage, César Jaramillo, Querube Fuenmayor, Brian Kubicki
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 occurs in an area of extensive, suitable habitat which appears not to be under threat, it has a presumed large population, and 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)

Population [top]

Population: In Costa Rica, this species is rarely seen and there is little information on its population status. Lips (1998) reported a sharp decline at Las Tablas (Costa Rica), but populations have persisted at Monteverde (Costa Rica) (Pounds et al., 1997). Further information is needed on the status of the species' populations in Panama.
Current Population Trend: Stable
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It inhabits relatively undisturbed, dense, primary humid montane forest. Breeding takes place by direct development.
Systems: Terrestrial

Threats [top]

Major Threat(s): In Panama, the major threat is logging. In Costa Rica the species is not threatened. The cause of the decline at Las Tablas has not been determined, but chytridiomycosis may be involved, as it was detected in this species at this location (Lips et al., 2003). It persists at Monteverde where chytrid has also been recorded (Pounds et al., 1997).

Conservation Actions [top]

Conservation Actions: It has been recorded from a number of protected areas in Costa Rica (including Parque Nacional Braulio Carrillo, and Parque Internacional La Amistad) and Panama (Parque Nacional Chagres and Parque Nacional Volcán Barú). Studies are needed to better understand the taxonomic relationship between this species and Pristimantis cruentus, so as to aid in the correct identification of populations (Gerardo Chaves, pers. comm.).
