Assessment Information [top]

Red List Category & Criteria:	Vulnerable B1ab(iii)+2ab(iii) ver 3.1
Year Published:	2008
Assessor/s:	Ignacio De la Riva
Reviewer/s:	Ariadne Angulo and Simon Stuart
Contributor/s:
Justification: 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.

Geographic Range [top]

Range Description:	Psychrophrynella chacaltaya is known from the type locality, Sanja Pampa (16 15' 13.8" S, 68 01' 41.8" W, 3900 masl), Province of Nor Yungas, Department of La Paz, and the nearby locality of Zongo Valley (16 11' 47"S, 68 07' 35" W, 3600 masl), 1.7 km above Central Botijlaca, Province of Murillo, Department of La Paz, Bolivia (De la Riva, 2007).

Population [top]

Population:	The species seems to be scarce in the Zongo Valley, as compared to Cotapata (De la Riva, 2007).
Population Trend:	Unknown

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.
Systems:	Terrestrial

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).
