Assessment Information [top]

Red List Category & Criteria: Least Concern 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 Least Concern as the species is thought to be common and somewhat adaptable, and there are no major threats to the species. However, given the impact of habitat loss within the range of the species, it is likely that the species is currently in decline.
History:
2000 Vulnerable
1996 Vulnerable

Geographic Range [top]

Range Description: This species, which has the largest range of any Phaner species, is patchily distributed along a narrow strip of western Madagascar forests from just south of the Fiherenana River, including the Forêts de Mikea, north to Soalala, from sea level to 800 m (Mittermeier et al. 2008). The northerly populations appear isolated and may possibly represent distinct taxa.

Population [top]

Population: Common. Population density estimates derived from studies in the Kirindy Forest and from Marosalaza are about 50-70 individuals/km² (Charles-Dominique and Petter 1980), but Ausilio and Raveloarinoro (1993) estimated densities of 300-400 individuals/km² in the forests of Tsimembo.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species is found in lowland forest habitats, and also in exotic tree plantations, perhaps suggesting reliance on tall canopy trees and gum. This is the best studied of the four Phaner species; its biology and ecology are summarized by Schulke (2003) and Mittermeier et al. (2008).
Systems: Terrestrial

Threats [top]

Major Threat(s): There are no major threats to this species, although habitat loss due to slash-and-burn agriculture, illegal logging, charcoal production, and annual burning to create pasture, may be resulting in localized declines.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. It is reported to occur in several national parks (Tsingy de Bemaraha, Tsingy de Namoroka, Zombitse, Vohibasia), the Tsingy de Bemaraha Strict Nature Reserve, and the Andranomena Special Reserve; it is also reported from the Analabe Private Reserve and the Kirindy Forest CFPF (Mittermeier et al. 2008). Forêts de Mikea is in the process of being declared part National Park and part Conservation Site. Taxonomy of the species, as with the genus, requires further investigation.
