Scientific Name: Hyloscirtus staufferorum (Duellman and Coloma, 1993)

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Luis A. Coloma, Santiago Ron
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in Ecuador.

Geographic Range [top]

Range Description:This species is known only from two localities in Napo Province, Ecuador: Volcán Sumaco, and the Cordillera de Guacamayos. It probably occurs a little more widely. Its altitudinal range is 2,040-2,500m asl.

Population [top]

Population:There is no information on the population status of this species.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It lives in very humid, low cloud forest, and breeds in streams. There is no information on its adaptability to secondary habitats.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The main threat is forest clearance due to agriculture, livestock farming, and wood extraction. It lives in montane habitats where catastrophic declines have affected other frogs with stream-dwelling larvae, probably as a result of chytridiomycosis.

Conservation Actions [top]

Conservation Actions: The geographic range of this species overlaps with Parque Nacional Sumaco. Continued and strengthened management of this reserve, and expanded protection of cloud forest elsewhere in the range of this species, are needed. Further survey work is necessary to determine its current population status, and whether chytrid poses a threat.
