Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(i,ii,iii,v) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30

Reviewer/s: Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
Justification:
Listed as Endangered as the species has a distribution range of less than 5,000 km², the range is severely fragmented, and there is continuing decline in the area and quality of habitat within the range of the species coupled with a loss of mature individuals due to hunting.
History:
2000 Vulnerable
1996 Vulnerable
1994 Vulnerable (Groombridge 1994)
1990 Vulnerable (IUCN 1990)
1990 Vulnerable (IUCN 1990)

Population [top]

Population: Sanford’s Brown Lemur occurs at higher densities on the slopes of Montagne d’Ambre and in other evergreen forests than it does in dry deciduous forests of the region, such as those of the Analamerana Special Reserve. On Montagne d'Ambre they are particularly common between 800 and 1,000 m (Freed 1996). In two sites in Analamerana, densities have been recorded at 3.5-5.5 individuals/km²; this species is less abundant and occurs at lower density than Crowned Lemurs in both Analamerana and Ankarana (Banks et al. 2007).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species is found in moist montane, such as on Montagne d'Ambre, and dry deciduous forests. In Ankarana National Park, it appears to favor secondary forest and is active both day and night. These lemurs are absent from very dry forests such as those of Cap d’Ambre, north of Antsiranana, but it is present in those of Daraina, to the south-east. In Ankarana groups may include up to 15 animals, significantly larger than those observed in Montagne d’Ambre, which range from three to nine animals. Mating occurs in late May and births usually take place in late September or early October (Mittermeier et al. 2008, and references therein). Often found associating with E. coronatus, especially in the wet season (Freed 1996).
Systems: Terrestrial

Threats [top]

Major Threat(s): The primary threat to the survival of Sanford’s Brown Lemur is habitat destruction, due to mining for sapphires and slash-and-burn practices, although it does appear to survive in degraded habitats. They are also hunted and commonly kept as pets.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. It is reported to occur in Montagne d’Ambre National Park and in two special reserves (Analamerana and Ankarana). The forests of Daraina, where it is also found, are slated to become a protected area. The species is also represented in captivity.
