Listed as Endangered because its extent of occurrence (EOO) is estimated to be 806 km2, most known subpopulations occur in habitat fragments, and there is continuing decline in the extent and quality of its habitat on the Pacific slopes.

Geographic Range [top]

Range Description:This species occurs on the Pacific slopes of the Cordillera de Talamanca of Costa Rica and extreme western Panama, from 880-1,524 m asl (Savage 2002). Its range, taken as a proxy for extent of occurrence (EOO), is estimated at 806 km2.

Population [top]

Population:It is moderately common in appropriate habitat. Recent survey work has been conducted at Las Cruces, Alfombra, and Tinamaste where the species has been recorded (G. Chaves and A. García pers. comm. 2013). It was recently observed in western Panama in Parque Internacional La Amistad (Hertz et al. 2012). The population is considered to be severely fragmented, with most subpopulations occurring in habitat patches isolated by urbanization or agriculture.

Current Population Trend:Stable
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:It is a nocturnal, stream-breeding species, present in humid montane forest and usually found along (and occasionally in) small streams and dense vegetation no more than one metre above the water.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: There are no reports of this species being utilized.

Threats [top]

Major Threat(s): The major threats to the species are the alteration of water flow in streams (for instance through hydroelectric projects), and general habitat destruction due to smallholder livestock ranching and more extensive agriculture (crops). Chytridiomycosis is also a potential threat to this species.

Conservation Actions [top]

Conservation Actions: Although present in protected areas such as Parque Internacional La Amistad and the Las Cruces Biological Station (the latter is part of the Reserva de la Biósfera La Amistad), much of the habitat in the range of this species is fragmented and in need of further protection. Research is needed on current threats, population trends, and natural history of this species.
