Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2008-11-07
Assessor(s): Luis A. Coloma, Santiago Ron, Diego Almeida
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 on the Amazonian slopes of the Ecuadorian Andes.

Geographic Range [top]

Range Description:This species is found on the lower Amazonian slopes of the Andes in northern and southern Ecuador (Sucumbios, Pastaza and Zamora Chinchipe Departments), at elevations of 1,100-1,600m asl. It might occur a little more widely.

Population [top]

Population:This species is noted as being uncommon across most of its range.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It lives in montane rainforest along streams with steep gradients (Lynch and Duellman, 1973). Reproduction is presumed to occur via eggs laid on vegetation, with the tadpoles developing in the water.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat destruction and degradation is a threat to this species, mainly as a result of smallholder farming activities and clear-cutting of forests. Predictions suggest that, in Ecuador, almost half of the habitats suitable for this species have been deforested (Cisneros-Heredia, 2008).

Conservation Actions [top]

Conservation Actions: Its distribution range overlaps with Parque Nacional Sumaco Napo-Galeras, Reserva Ecológica Antisana, Parque Nacional Podocarpus and Parque Nacional Llanganates.
