Sibree’s dwarf lemur was believed extinct following the destruction of its first recorded forest habitat, though they were found in their high altitude habitat on Mount Maharira in Ranomafana National Park, Madagascar, as well as in Tsinjarivo, where it may be restricted by rivers.
Sibree’s dwarf lemur is most threatened by fragmented, degraded habitat, as it is not known to occur in any protected areas, with no safeguards in place for this species. Very little is known about the ecology and behaviour of this mysterious species. Lemurs are part of a group of the most basal living primates, and they have been independently evolving on the island of Madagascar for 50-60 million years.
- Order: Primates
- Family: Cheirogaleidae
- Population: Unknown
- Trend: decreasing
Found only in Ranomafana National Park and Tsinjoarivo, Madagascar. In Ranomafana they are only found on Mount Maharira. In Tsinjoarivo they may be restricted by the Onive and Mangoro rivers, Anjozorobe, and the corridor to the western half of Tsinjoarivo Forest above 1,400m altitude.
Habitat and Ecology
Sibree’s dwarf lemurs’ live in the high altitude rainforests of Madagascar, and little is known of their ecology.
