Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Wilmar Bolívar, Luis A. Coloma, Santiago Ron, Taran Grant
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Near Threatened since although this species is still relatively widely distributed, it has declined seriously in Ecuador (possibly due to chytridiomycosis), and its overall status is therefore of concern.

Geographic Range [top]

Range Description:This species occurs widely in the Western and Central Cordilleras, from Antioquia Department in Colombia, south to Cotapaxi and Las Pampas Provinces in northern Ecuador, from 1,460-2,120m asl.

Population [top]

Population:It is still common in Colombia, but it has not been recorded in Ecuador since October 1990, despite extensive survey efforts.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It lives on the ground in very humid montane forest, and has also been found in open fields and very modified areas, but is always near streams. The eggs are laid in leaf-litter, and the male transports the larvae to slow-flowing streams.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The serious declines noted in Ecuador can possibly be attributed to chytridiomycosis. Additional likely threats are: deforestation, due to agricultural development, cultivation of illegal crops, fire, logging, and human settlement; introduction of alien predatory fish species in streams; and pollution resulting from the spraying of illegal crops.

Conservation Actions [top]

Conservation Actions: It occurs in several protected areas in Colombia, while in Ecuador, its geographic range overlaps with the Reserva Ecológica Los Illinizas. In view of the risk of chytridiomycosis, an ex situ population may need to be established.
