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, presumed large population, it occurs in a number of protected areas, has a tolerance of a degree of habitat modification, and because it is increasing and recolonising former localities.
Previously published Red List assessments:
2008 Least Concern (LC)
2004 Least Concern (LC)

Geographic Range [top]

Range Description: This species is found in humid lowlands on the Atlantic versant from north-eastern Honduras to central Panama, both slopes of the cordilleras of Costa Rica and western Panama, the lowlands of south-western Costa Rica and eastern Panama, and gallery forests in non-peninsular north-western Costa Rica, from sea level up to 1,740m asl (Savage, 2002).
Countries occurrence:
Costa Rica; Honduras; Nicaragua; Panama

Population [top]

Population: Once a common species, it initially declined in many montane areas of Costa Rica. It disappeared from Tapantí and the higher regions of Monteverde by the late 1980s, and disappeared at the same time from San Ramón Reserve but reappeared in 1994. It also appears to have declined at La Selva, a lowland site (Whitfield et al., 2007). It is still abundant in Tinamascas (along the road from San Isidro to Dominical), Parque Nacional Corcovado, and Ciudad Colón. It remained generally common at low elevations, and as of August 2007, the species was recolonising areas from which it had previously declined.
Current Population Trend: Increasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: This is a diurnal species associated with small streams in humid lowland, montane and gallery forest. It is found wherever patches of forest remain, even within urban areas. Larvae are found in small streams.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): It is generally threatened by habitat loss (deforestation) resulting from agricultural development, logging, and development of human infrastructure. The disappearances at higher altitudes may have been due to chytridiomycosis, however animals are now recolonising these sites. 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, this species has been recorded from many protected areas. It should be monitored carefully to establish whether or not the disappearances at higher altitudes was due to chytridiomycosis, and how the species is recolonising these sites.
