Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2010-11-02
Assessor(s): IUCN SSC Amphibian Specialist Group,
Reviewer(s): Crnobrnja-Isailovic , J. & Kusrini, M.D.
Contributor(s): Angulo, A., Icochea M., J., Martinez, J., Jungfer, K., Reynolds, R. & Arizabal, W.
Facilitator/Compiler(s): Bowles, P.
Justification:
This species is listed as Least Concern since, although its extent of occurrence is probably less than 20,000 km², it occurs in an area of extensive, suitable habitat which appears not to be under significant threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species' geographic range is the northeastern slope of the Andes of Peru, within the Cordillera Central (Departments of Amazonas and San Martin). Known localities lie within the Río Cainarachi drainage (two sites) and the Río Marañón valley (two sites) (Duellman 2004); the species might occur more widely. It has an estimated altitudinal range of 400–1,700m asl (Aguilar et al. 2010).

Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a diurnal, terrestrial species known from both humid and dry pre-montane and lowland forest (Duellman 2004). The species is associated with streams. Larvae are carried to streams by the female. It has been recorded from disturbed (partially cutover) rainforest (Duellman 2004), implying tolerance of some degree of habitat modification.
Systems:Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: There are no reports of this species being utilized. However, Peruvian species of Hyloxalus, in common with other poison dart frogs, may be at risk from smuggling to support the international pet trade (von May et al. 2008).

Threats [top]

Major Threat(s): Because of the large areas of suitable habitat available in protected areas to this species there are no major threats. Outside protected areas, there is some localized habitat loss through different human activities, principally agriculture.

Conservation Actions [top]

Conservation Actions: This species occurs within the Santiago Comaina Reserved Zone and the Alto Mayo protected area; no species-specific conservation measures are known. More information is needed on extent of occurrence, area of occupancy, population status, natural history and threats.
