Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Wilmar Bolívar, Luis A. Coloma, Santiago Ron, Diego Cisneros-Heredia
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 in Colombia and Ecuador.

Geographic Range [top]

Range Description:This species is known only from the Nudo de Pasto area on the eastern slopes of the Andes in southern Colombia and northern Ecuador. In Ecuador, it has been recorded only in the extreme north-eastern páramos around Sánta Barbara on the Cordillera Oriental on the border with Colombia. It has been recorded at about 1,950-2,700m asl.

Population:It is a rare species.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:A cloud forest species, it has also been found in partially cleared forest, where frogs were found at night on branches of trees above a stream. However, its adaptability to disturbed habitats is not well known. It breeds in streams.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threats are likely to be deforestation due to agricultural development, planting of illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops. All known localities in Ecuador are subject to severe human disturbance. The species 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: It is not known from any protected areas, and there is an urgent need to expand the protected area coverage in the Colombian Andes. Research is needed to determine the current population status of this species and to ascertain whether chytrid poses a threat.
