Reviewer(s): Molur, S. & Schwitzer, C.
Facilitator/Compiler(s): Chiozza, F.
Justification:
Listed as Vulnerable as the species is suspected to have undergone a population decline of ≥30% over a period of 15 years (three generations), due primarily to continuing decline in area, extent and quality of habitat. These causes have not ceased, and will to a large extent not be easily reversible. A population reduction of ≥30% is also suspected to be met in the future (over a period of three generations) due to the same causes.

Population [top]

Population:In decline due to habitat loss, though fortunately, the species still appears to be relatively widely distributed.
Current Population Trend:Decreasing
Additional data:
♦ Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:It inhabits tropical moist lowland forests. Nocturnal and arboreal. Undoubtedly gums form a major part of the diet (Mittermeier et al. 2010 and references therein).
Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):5

Threats [top]

Major Threat(s): The major threats include habitat loss due to slash-and-burn agriculture, and illegal logging.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. It is reported from two national parks (Masoala and Zahamena), two nature reserves (Betampona and Zahamena), the Ambatovaky Special Reserve, and the forests of Makira (which are slated for official protection), and it may occur in the Mananara-Nord National Park (Mittermeier et al. 2010). May also occur in Marotandrano Special Reserve. Taxonomic studies to determine the status of the species, and further surveys on population numbers and range.
