Assessment Information [top]

Red List Category & Criteria: Critically Endangered B2ab(iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Vences, M. & Nussbaum, R.
Reviewer(s): Stuart, S.N., Chanson, J.S. & Cox, N.A.
Listed as Critically Endangered because its Area of Occupancy is probably less than 10km2, all individuals are in a single sub-population, and the extent of its forest habitat on the Ankaratra Massif is declining.
Previously published Red List assessments:
2004 Critically Endangered (CR)

Geographic Range [top]

Range Description: This species occurs in a single, small area at 2,200m asl on the Ankaratra Massif in central Madagascar. This site is within 443m of the highest Ankaratra summit (2,643m asl).

Population [top]

Population: In the last 20 years, it has only been recorded in a single stream, where it is known to be rare. Despite recent survey work, it has not been found at other locations on the Ankaratra Massif.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: Although it originally lived in montane rainforest, it is now known only in high-altitude grassland with forest remnants. It breeds in fast-flowing mountain streams.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The main threats to its habitat on the Ankaratra Massif are fire, overgrazing by livestock, and expanding potato farming. However, water pollution and stream sedimentation as a result of agriculture and mining might also be threats. As a mountain top species, it could also be at risk from the effects of global warming.

Conservation Actions [top]

Conservation Actions: It is not known from any protected areas, and the protection of remaining habitat (including important streams) on the Ankaratra Massif is urgently needed. Further survey work is needed to determine whether or not the species might survive elsewhere on the Massif, and to determine the current population status of the species.
