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, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in Ecuador.
This species occurs at 1,200-1,800m asl on the Pacific slopes of the Cordillera Occidental in Ecuador, from the provinces of Imbabura and Esmeraldas, south to Bolivar. It has been recorded from around ten localities.
It is a cloud forest species that lives in bromeliads by day. At night, individuals have been found on ferns and leaves up to 2m above the ground, in dense forest, and along streams. It is not known whether or not it can adapt to disturbed habitats. It is presumed to breed by direct development, but the site of egg deposition is not known.
Habitat destruction and degradation are taking place due to agricultural development, plantations, logging, and human settlement. 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.
