Scientific Name: Pristimantis quinquagesimus (Lynch and Trueb, 1980)
Eleutherodactylus quinquagesimus Lynch and Trueb, 1980

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Fernando Castro, Maria Isabel Herrera, Santiago Ron, Luis A. Coloma, Mario Yánez-Muñoz, John Lynch, Diego Cisneros-Heredia
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 in the Ecuadorian and Colombian Andes.

Geographic Range [top]

Range Description:This species can be found at elevations of 1,410-2,710m asl, on the Pacific slopes of the western Andes in Ecuador, and in extreme southern Colombia, in Nariño Department, at elevations of 1,700-2,600m asl.
Countries occurrence:
Colombia; Ecuador

Population [top]

Population:Locally common (for example, in Intag, Imbabura, Ecuador, in 2003), this species has disappeared from some localities where it was known to exist historically. For example, it was common when it was collected in the Quebrada Zapadores, Ecuador in the 1970s, but had disappeared by 1997 at this locality despite a lack of habitat disturbance.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species occurs in cloud forest in the humid temperate regime and humid subtropical regime. Most individuals have been found perched on leaves and branches at heights up to 2.5m above the ground, but one was found sitting amidst dead bamboo leaves on the ground (Lynch and Duellman 1997); they are sometimes found near streams. It is presumed to breed by direct development, though the site of egg deposition is not known. The ability of this species to adapt to modified habitats is unknown.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat loss caused by logging, agricultural development (livestock ranching and illegal crops), and human settlement is a major 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 [top]

Conservation Actions: In Colombia most of the populations are inside La Planada Natural Reserve. In Ecuador, its range overlaps with Reserva Ecológica El Angel, Reserva Ecológica Cotacachi-Cayapas, and Reserva Ecológica Los Illinizas.
