Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii) ver 3.1
Year Published: 2012
Date Assessed: 2010-12-17
Assessor(s): Rakotoarinivo, M. & Dransfield, J.
Reviewer(s): Baker, W.J., Beentje, H.J. & Bachman, S., Baker, W.J. & Beentje, H.J.
Justification:
Known from a single locality where the forest extent is estimated to be only 19 km² (extent of occurrence). The area is protected but the habitat is threatened by human activities, such as fire and harvesting, outside the reserve and this is treated as a continuing decline in extent and quality of habitat. The species meets the requirements for listing as Critically Endangered.
History:
1998 Critically Endangered
1997 Endangered (Walter and Gillett 1998)

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: The species inhabits lowland rainforest at the foot of slopes between 10 and 100 m asl.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: There is no information on use of this species.

Threats [top]

Major Threat(s): Although the area is protected the habitat outside is being heavily impacted by human activities such as increased frequency of fires to clear land for shifting agriculture, logging and other harvesting. Given the small size of the forest reserve, this area is probably also being impacted.

Conservation Actions [top]

Conservation Actions: Protected in the Manombo Reserve.
