Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Luis A. Coloma, Santiago Ron, Diego Cisneros-Heredia, Fernando Castro, Jose Vicente Rueda
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Near Threatened because this species is probably in significant decline (but probably at a rate of less than 30% over ten years) because of widespread habitat loss through much the majority of its range of its range, thus making the species close to qualifying for Vulnerable.

Geographic Range [top]

Range Description:This species occurs in the lower Amazonian slopes of the Andes in Ecuador, Peru and Colombia (Caquetá to Putumayo), from 300-2,000m asl.

Habitat and Ecology [top]

Habitat and Ecology:Individuals have been found in dense cloud forests where it favours perches, being found on the branches of bushes and small trees (Trueb 1974). At Cordillera del Cutucú, Ecuador, specimens have been collected in very wet forest, where the ground and most trees were covered with moss (Duellman and Lynch 1988); it was also collected at the same habitat type in Peru. It is not present in modified habitats. This species reproduces by direct development and the eggs are carried in a pouch on the female's back. It is probably a specialized predator on other frog species that only survives in areas of high frog density.

Threats [top]

Major Threat(s): This species is threatened by forest loss due to infrastructure development for human settlements, logging, and agricultural development (including for the cultivation of crops and the rearing of livestock). Although much forest habitat remains within the range of this species, it is very sensitive to slight habitat alteration and the rate of forest loss within the majority of its range (the Ecuadorian portion) is very high.

Conservation Actions [top]

Conservation Actions: Its geographic range overlaps with the Reserva Ecológica Cayambe-Coca, Parque Nacional Sumaco Napo-Galeras, and Parque Nacional Sangay, in Ecuador. In Peru it is present in the Zona Reservada Santiago-Comaina.
