Population [top]

Population: Recent searches in Cerro Chompipe, a known historical locality that has not suffered much habitat modification, have not found this species, although it continues to be seen at Cerro de la Muerte and several other localities within its range.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: A nocturnal stream-breeding treefrog occurring in fast-flowing streams in lower montane and montane rainforests. Males call from rocks in streams and along stream margins, and sometimes from low vegetation near streams. Tadpoles typically are found adhering to large rocks in cold mountain streams (Savage 2002).
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Major threats include habitat destruction, pollution, and climate change. The decline witnessed at Cerro Chompipe could be due to chytridiomycosis.

Conservation Actions [top]

Conservation Actions: Much of the species' range is included within national parks, including Parque Internacional La Amistad. There is a need for close population monitoring of this species, given the potential threat of chytridiomycosis.
