Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Luis A. Coloma, Santiago Ron, Diego Cisneros-Heredia, Ana Almendáriz
Reviewer(s): 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, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat on the Pacific slopes of the Ecuadorian Andes.

Geographic Range [top]

Range Description: This species is known from more than ten localities on the lower Pacific slopes of the Andes, from the province of Cotopaxi northwards to the province of Carchi in Ecuador. It is also likely to occur in adjacent Colombia, although there are, as yet, no confirmed records. It ranges from 600-1,540m asl.

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: An inhabitant of humid premontane forest; most individuals have been observed in the immediate vicinity of streams (Lynch and Duellman 1997). Breeding takes place by direct development.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat to this species is habitat loss and degradation, which has been particularly severe in the last few years due to agriculture (both crops and livestock) and logging; pollution due to agriculture is also a threat. It should be noted that some other species of Craugastor 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 [top]

Conservation Actions: Its range overlaps slightly with Reserva Ecológica Cotacachi-Cayapas and Reserva Ecológica Los Illinizas.
