Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii,v) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor/s: Andrainarivo, C., Andriaholinirina, V.N., Feistner, A., Felix, T., Ganzhorn, J., Garbutt, N., Golden, C., Konstant, B., Louis Jr., E., Meyers, D., Mittermeier, R.A., Perieras, A., Princee, F., Rabarivola, J.C., Rakotosamimanana, B., Rasamimanana, H., Ratsimbazafy, J., Raveloarinoro, G., Razafimanantsoa, A., Rumpler, Y., Schwitzer, C., Thalmann, U., Wilmé, L. & Wright, P.
Reviewer/s: Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
Justification:
Listed as Endangered as the species has a distribution range of less than 5,000 km², the range is severely fragmented, and there is continuing decline in the area and quality of habitat within the range of the species as well as a continued decline in the number of mature individuals due to hunting.

Geographic Range [top]

Range Description: This species is found in northern Madagascar in the forests of Montagne d’Ambre, Ankarana, Andrafiamena, and Analamerana, from low elevations to 1,500 m.

Population [top]

Population: Common, though not in Montagne d' Ambre. Population densities have been variously estimated between 150 and 550 individuals/km² (Ratsirarson and Rumpler 1988; Hawkins et al. 1990), the higher figures coming from more humid forest environments such as Ankarana.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Occurs in dry deciduous forests and also in moist evergreen forest. The natural history of this species remains poorly studied by comparison to that of sportive lemurs inhabiting western and southern Madagascar. Adults seem to remain solitary during nightly bouts of foraging for leaves. Tree holes and vine tangles are preferred daytime shelters.
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threats to this species are forest loss, particularly for charcoal (such as in Analamerana and Andrafiamena), and hunting (exacerbated by mining in the region for sapphires).

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. The species is found in Montagne d’Ambre National Park and in three special reserves (Analamerana, Ankarana, and Fôret d’Ambre), as well as in the Andrafiamena Classified Forest (Mittermeier et al. 2008). Improved management and protection of Analamerana is urgently required, and long-term scientific presence within the existing reserve is encouraged. Andrafiamena should be included within a protected area.
