Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Annotations:

Assessor(s): Wilmar Bolívar, Luis A. Coloma, Santiago Ron, Diego Cisneros-Heredia, Karl-Heinz Jungfer
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Near Threatened because its Area of Occupancy is probably not much greater than 2,000 km2, and its clear stream habitat is in decline, thus making the species close to qualifying for Vulnerable.

Population:It is locally very common in suitable habitats.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It lives on vegetation inside lowland and montane forests, usually very close to streams. Specimens have been found calling from vegetation over, and boulders in, cascading mountain streams. It can survive in secondary forest if vegetation persists around streams. The eggs are deposited among rocks at the water's edge, and the larvae develop in streams.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat is habitat loss due to agricultural development (including cultivation of illegal crops), logging, and human settlement, and pollution resulting from the spraying of illegal crops. It is probably also affected by the introduction of exotic fish species, pollution from agriculture, and droughts.

Conservation Actions [top]

Conservation Actions: In Ecuador, its geographic range overlaps with the Reserva Ecológica Los Illinizas and the Reserva Ecológica Manglares Churute. In Colombia it has been recorded from Parque Nacional Natural Farallones de Cali.
