Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Glaw, F., Vences, M. & Cadle, J.
Reviewer(s): Stuart, S.N., Chanson, J.S. & Cox, N.A.
Listed as Near Threatened since the species depends on streams in a dry environment, and so its Area of Occupancy is probably not much greater than 2,000 km2, and the extent and quality of its habitat is declining, thus making the species close to qualifying for Vulnerable.
Previously published Red List assessments:
2004 Near Threatened (NT)

Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat to this species is rapid habitat loss and degradation due to subsistence agriculture, timber extraction, charcoal manufacture, livestock grazing, fires and expanding human settlements. It is probably also affected by pollution of its breeding streams.

Conservation Actions [top]

Conservation Actions: It occurs in Parc National de Isalo and is likely to occur in the Réserve Spéciale de Kalambatritra, although it has not yet been found there. It also occurs in one planned protected area (Sahamalaza).
