Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Claudia Cortez, Steffen Reichle, Ignacio De la Riva, Jörn Köhler
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:This species occurs on the eastern slopes of the Bolivian Andes, in the departments of Cochabamba and Santa Cruz, at 1,600-2,400m asl (Köhler 2000).
