From the IUCN Red List Species Account:

Range Description

This species can be found at moderate elevations (1,150-1,800m asl) along the eastern face of the Cordillera Oriental from southern Colombia (Caquetá) to southern Ecuador.

Habitat and Ecology

This species occurs in cloud forest. One individual was found on the forest floor by day, while others were found on the ground at night; some individuals have been found on stream banks (Lynch and Duellman 1980). Reproduction occurs by direct development.

Population

This is a rare species across its range; it has not been seen since 1990 in Colombia, although there has been little survey work.

Population Trend

Unknown

Major Threats

Habitat destruction and degradation due to agriculture (including the planting of illegal crops), human settlement, and logging is the main threat. Some other species of Eleutherodactylus that are associated with streams have undergone dramatic declines and disappearances, possibly due to chytridiomycosis, so the status of this species should be monitored carefully.

Conservation Actions

In Ecuador, it occurs in Parque Nacional Podocarpus, and its range overlaps with Reserva Ecológica Cayamabe-Coca, and Parque Nacional Sumaco Napo-Galeras. In Colombia, it occurs in Parque Nacional Natural Alto Fragua-Indi Wasa.
