Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-11-17
Assessor(s): Carmen Úbeda, Ramón Formas, Helen Díaz-Paéz, Esteban Lavilla, Néstor Basso
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Least Concern in view of its relatively wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.
2004 Least Concern

Population [top]

Population: It is common in pristine habitats. There are large populations of this species.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It is widely distributed in Nothofagus forest with Mediterranean or oceanic influences; humid temperate forests; bogs, marshes and wetlands surrounded by forest; shores of ponds and lakes surrounded with swamps. It may be found under logs; males calls from crevices under moss close to streams. Eggs are deposited under logs or moss; following rain the egg deposition site becomes flooded and larvae develop in the floodwater. It tolerates some deforestation.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): There is some habitat destruction and degradation including exotic tree plantations and human settlements, mainly in the north part of the range.

Conservation Actions [top]

Conservation Actions: It occurs in many protected areas. Legislation to preserve the Nothofagus forest habitat is needed.
