Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Wilmar Bolívar, Luis A. Coloma, Santiago Ron, Mario Yánez-Muñoz, Taran Grant
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in Colombia and Ecuador.

Geographic Range [top]

Range Description:This species occurs on the Pacific slopes of the Cordillera Occidental in Colombia, in Antioquia, Choco, Cauca, Valle del Cauca, Nariño and Risaralda Departments, south to Cotopaxi Province in adjacent Ecuador. It is also known from the eastern slopes of the Cordlillera Central in the Department of Caldas, Colombia. In Ecuador it has been recorded from only five sites covering a relatively small area. It has been recorded at 1,780-2,650m asl.

Population [top]

Population:It is very common in Colombia, but uncommon in Ecuador where it appears to have disappeared from Quebrada Zapadores in Pichincha Province, where it once occurred.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It occurs on vegetation next to streams in montane forests, and is perhaps a little more arboreal than some other related species. It is not found in degraded habitats, but does occur in selectively logged forest. It breeds in streams, with the eggs laid on leaves overhanging the water.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat is habitat loss as a result of deforestation for agricultural development (including the planting of illegal crops), logging, and human settlement. Other threats include the introduction of alien predatory fish, and pollution resulting from the spraying of illegal crops. Like some other centrolenids, this species might also be affected by the movement of the cloud layer up the mountain sides as a result of climate change, resulting in reduced humidity within the altitudinal range of the species (probably exacerbated by habitat fragmentation). Chytridiomycosis is a possible future threat.

Conservation Actions [top]

Conservation Actions: It occurs in several protected areas in Colombia, while in Ecuador its range overlaps with Reserva Ecológica Los Illinizas.
