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 although the precise limits of distribution of this species are unclear in the wake of recent taxonomic investigations, it is believed to remain widespread and abundant, with no major threats resulting in significant range-wide population declines.
History:
1990 Abundant (IUCN 1990)

Geographic Range [top]

Range Description: This species is endemic to the island of Madagascar. Groves (2000, 2001), in revising the genus, limited its range to the dry forests of western Madagascar. However, subsequent field studies and genetic analyses have extended the species' range all the way to the southern tip of Madagascar and into the evergreen humid forest of Saint Luce, 40 km north-east of Tolagnaro in southeastern Madagascar (Hapke et al. 2005). The range of the species relative to C. adipicaudatus is not clear. Ranges from sea-level to 800 m.

Population [top]

Population: Cheirogaleus medius is an apparently widespread and abundant species. It occurs at densities estimated to range between 40-400 individuals/km² (see Mittermeier et al. 2008 and references therein).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species inhabits dry deciduous forests. Individual home ranges approach 1-2 hectares. Small family groups consist of the reproductively-active pair and their offspring from one or two breeding seasons. Daylight hours are spent in tree holes during the day, with up to five individuals occupying a single shelter. Litter sizes range from one to four, but twins are most common and the young are born with eyes open and covered with fur. Both males and females take part in raising the young. Sexual maturity is reached during the second year of life (see Mittermeier et al. 2008 and references therein).
Systems: Terrestrial

Threats [top]

Major Threat(s): There are probably no major threats, but habitat loss, primarily due to slash-and-burn agriculture, charcoal extraction, and bushfires may be resulting in localized declines.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. Its presence is reported from five national parks (Andohahela, Ankarafantsika, Kirindy Mitea, Tsingy de Namaroka and Baie de Baly) and five special reserves (Andranomena, Ankarana, Bemarivo, Maningoza and Beza-Mahafaly) (Mittermeier et al. 2008). Taxonomic work is urgently required to elucidate more clearly the taxonomic and geographic limits of the species.
