Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Ignacio De la Riva
Reviewer(s): Ariadne Angulo and Simon Stuart
Listed as Vulnerable in view of its extent of occurrence of less than 20,000 km2, area of occupancy of less than 2,000 km2, with all individuals in fewer than ten locations, and a projected decline in the extent and quality of its habitat due to climate change and habitat loss.

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

Habitat and Ecology [top]

Habitat and Ecology:Individuals of this species can be found under stones or amid grasses and mosses in paramo, usually occupying different
microhabitats with a variable degree of humidity, commonly around small lakes which are sometimes associated with Polylepis formations. Males can be heard to call by day and night, with or without rain (De la Riva, 2007).

The species presumably has direct development.

Threats [top]

Major Threat(s): The species could be affected by the removal of Polylepis formations and agriculture in Zongo Valley. In addition, its restricted distribution and the predicted effects of climate change (e.g. drying up of regions) are also considered to pose serious threats to the species (I. De la Riva, pers. comm. 2008).

Conservation Actions [top]

Conservation Actions: The species occurs within the Cotapata National Park and Natural Area of Integrated Management (PN-ANMI Cotapata).
