From the IUCN Red List Species Account:

 

Range Description

This species can be found along the eastern slopes of the Ecuadorian Andes in the Río Pastaza Valley (1,180-1,800m asl), southern Ecuador (Provincia de Morona-Santiago, from 2,195-2,835m asl), Cordillera del Due (1,150-1,700m asl), and Parque Nacional Podocarpus (Curintza, 2,600m asl).

Habitat and Ecology

This species inhabits cloud forests. The frogs have been found on low vegetation and rocks, usually along streams, at night (Lynch and Duellman 1980). Breeding takes place by direct development.

Population

It is a rare species in parts of its range, for example, at Parque Nacional Podocarpus where it was last seen in 1997.

Population Trend

Decreasing

Major Threats

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

Conservation Actions

Its range overlaps with several protected areas including Parque Nacional Sumaco Napo-Galeras, Parque Nacional Llanganatis, Parque Nacional Sangay, and Parque Nacional Podocarpus.
