Population [top]

Population: Although it has been well studied and collected extensively, and was formerly abundant throughout its range, it has not been recorded despite extensive directed surveys since 1986. There have been no new records as of August, 2007. A serious decline appears to have taken place and there is now considered to be no doubt that the species is extinct (F. Bolaños and G. Chaves pers. comm.).

Habitat and Ecology [top]

Habitat and Ecology: It has been recorded along streams in premontane and lower montane rainforest; with breeding taking place on land by direct development at stream margins.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The most likely cause of its disappearance in suitable habitats is the disease chytridiomycosis, perhaps in combination with climate change or other, unknown, factors.

Conservation Actions [top]

Conservation Actions: The species was well protected in Parque Nacional Braulio Carrillo. It was formerly suggested that any surviving individuals might need to form the basis for the establishment of a captive-breeding programme.
