Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2008-10-27
Assessor(s): Wilmar Bolívar, Luis A. Coloma, Santiago Ron
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
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 on the Ecuadorian and Colombian Andes.

Population [top]

Population:There is very little information, since there are only a few records of this species.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a species of cloud forest. Specimens have been found on stems and branches of bushes near, or over, streams at night. There is no information on its adaptability to secondary habitats. It presumably breeds in streams.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threats are likely to be deforestation due to agricultural development, the planting of illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops. The species also lives in montane habitats where catastrophic declines have affected other frogs with stream-dwelling larvae, probably as a result of chytridiomycosis.

Conservation Actions [top]

Conservation Actions: In Ecuador, its geographic range overlaps with the Reserva Ecológica Cayambe-Coca, the Reserva Ecológica Antisana, Parque Nacional Llanganates, and Parque Nacional Sangay. It is not known from any protected areas in Colombia. Further research is necessary to determine the current population status of this species in the wild, and whether chytrid poses a threat.
