Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Bolaños, F., Chaves, G., Wake, D. & Savage, J.
Reviewer(s): Stuart, S.N., Chanson, J.S., Cox, N.A. & Young, B.E.
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat, and in the number of mature individuals, in Costa Rica.

Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It lives in lower montane and montane rainforests, being found in talus on steep slopes, and on road cuts, but generally not in degraded habitats. It breeds by direct development and is not dependent upon water.

Threats [top]

Major Threat(s): Habitat loss has been taking place throughout the range, but this probably is not sufficient to explain the levels of decline observed in the species. Declines that have taken place in suitable habitat could be the result of other threats such as climate change or disease (possibly chytridiomycosis, although this normally impacts species that are associated with water).

Conservation Actions [top]

Conservation Actions: It is not known from any protected areas, though it might occur in Parque Nacional Chirripo. There is a need for close population monitoring of this species, and research is also necessary to investigate the reasons for the decline of this species in suitable habitat.
