Justification:
The extent of occurrence (EOO) of this species covers less than 700 km2. This geographic range is severely fragmented and undergoing continuing decline in area, extent and quality of habitat. Based on these premises, the species is listed as Endangered.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species is presently known only from Manongarivo Special Reserve in northwestern Madagascar, from an isolated population on the Ampasindava Peninsula, and possibly from the forests of Mahilaka-Maromandia (Mittermeier et al. 2008). It lives from 360 to 1,600 m above sea level. The extent of occurrence (EOO) is estimated as less than 700 km2.

Native:
Madagascar
Additional data:
Continuing decline in extent of occurrence (EOO):Yes
Lower elevation limit (metres):360
Upper elevation limit (metres):1600

Population [top]

Population:This species is in decline due to habitat loss and degradation.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:The Sambirano Mouse Lemur is named for the region where elements of Madagascar’s humid eastern and dry western forests meet. It can be found in disturbed habitats and in forests bordering agricultural sites. It has been observed in a garden close to secondary forest. No systematic studies of this species’ ecology or behaviour have been conducted to date.
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): The major threat is habitat loss due to slash-and-burn agriculture, firewood collection, and charcoal production. The species does display some adaptability to disturbed habitats.


Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. The only protected area where it is known to occur is the Manongarivo Special Reserve. There are no specimens reported in captivity at this time (ISIS 2009). The remaining forest on the Ampasindava Peninsula requires protection.
