Assessment Information [top]

Red List Category & Criteria: Data Deficient 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 Data Deficient as the species is very poorly known, and there is very limited information available on its distribution or population status. However, given known threats, and assuming a restricted distribution, the species may warrant listing either as Vulnerable or Endangered based on criterion B.
History:
2003 Not Evaluated (IUCN 2003)
2003 Not Evaluated

Geographic Range [top]

Range Description: This relatively newly described species is probably restricted to the Sambirano region in north-western Madagascar, including the Ampasindava Peninsula (Thalmann and Geissmann 2000). The northern extent of its distribution is possibly the Sambirano River and the southern limit either the Andranomalaza or Maevarano River. It also has been reported from the western slopes of the Manongarivo Special Reserve (identified by Raxworthy and Rakondroparany, 1988 as A. laniger; reclassified by Thalmann and Geismann 2000). Sea level to 700 m.

Population [top]

Population: Unknown. Known only from a few specimens.
Population Trend: Unknown

Habitat and Ecology [top]

Systems: Terrestrial

Threats [top]

Major Threat(s): Deforestation through slash-and-burn agriculture (even on steep slopes) and for charcoal production, which may be sold in Nosy Be, are likely the main threats. The degree to which the species is hunted is not known.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. The only protected area in which this species is believed to occur is the Manongarivo Special Reserve, where it is known only from the western slopes. The only protected area in which A. unicolor occurs is the Manongarivo Special Reserve, where it is known only from the western slopes. Consideration should be given to establishing a protected area on the Ampasindava Peninsula and extending the boundaries of the Manongarivo Special Reserve eastward (Mittermeier et al. 2008). Additional research on population numbers and range and biology and ecology are essential.
