Justification:

This species has a very small remaining total population of about 500 individuals. The number of mature individuals is about 125 and is ontinuing to decline. There is a restricted population structure with 90-100% of all mature individuals being in one subpopulation. The species is threatened mainly by habitat destruction through slash-and-burn agriculture, but also by hunting. Based on these premises, the species is listed as Critically Endangered. 

History:
2000 Critically Endangered
1996 Critically Endangered
1990 Endangered (IUCN 1990)

Geographic Range [top]

Range Description:This species has a very restricted range in northern Madagascar that includes the Analamerana Massifs. It was formerly recorded in the Ankarana forests (where it may not have been resident), but has not been recorded at all during recent surveys, although animals were observed in forest fragments between Analamerana and Ankarana (Banks et al. 2007). Ranges from sea level to 400 m.

Population [top]

Population:

This is one of the rarest and most endangered lemurs (and indeed of all the world's primates). The total population is less than 500 individuals, and the effective breeding population is only approximately 125 individuals. 

Mathew Banks and James Herrera (pers. comm. 2013) estimate the following population densities at the following sites: Ambatovazaha - 45.73 individulas/km2; Ampasimaty - 3.54 individulas/km2; Ampondrabe - 1.48 individulas/km2; Andampibe - 34.85 individulas/km2; Andrafiambany - 7.91 individulas/km2; Madiromasina - 5.06 individulas/km2; Mahanoro - 6.5 individulas/km2; Antsahabe – 0 individulas/km2. The overall mean of densities estimated at each site separately is 8.78 individulas/km(these results were generated from using a global detection probability, estimated from all the data within the truncation distance, not for each site separately).

Notably, population densities of Sifakas on sandstone soil are more than twice the population density found on limestone soils.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species is an inhabitant of tropical dry forest. The diet consists mainly of leaves (both young and mature), unripe fruits, stems, and flowers. At least a dozen different varieties of plants, representing nine families, have been identified as food sources. Groups range in size from two to six individuals and home ranges approach 30 ha (Mittermeier et al. 2008, and references therein). Densities of fossa are extremely high in this region, and this carnivore could be having a negative impact on lemur populations.

 

Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is hunted for food.

Threats [top]

Major Threat(s): Slash-and-burn activities resulting in forest loss represents the greatest threat to this species. Additional threats include fires set to increase livestock pasture, the cutting of trees to produce charcoal, forest destruction caused by itinerant miners, and hunting. During the dry season, they drink water on the ground, and when they move between forest patches they move along the ground where their conspicuous colouration makes them vulnerable to predators and hunters.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. One of the rarest and most endangered lemurs (and indeed of all the world's primates). The total population could be as few as 500, and the effective breeding population only 125 individuals. The only protected area in which it is known to occur is the Analamerana Special Reserve. A small number may still be found as well in the eastern section of Ankarana National Park, which is connected through a series of forest patches to populations at Andriafiamena and Analamerana. It has recently been seen in unprotected forest patches between Analamerana and Ankarana, and is present in the Andavakoera Classified Forest, but probably in very low numbers. There is an urgent need for a full-time, long-term scientific presence in the Analamerana Special Reserve, as well as an expansion of this protected area to include the forests of Andriafiamena and a connection to Ankarana. This effort should also include an education campaign in the region, as well as surveys in nearby forest patches to look for any other populations. This species is not being kept in captivity. Research into sifaka captivity is needed to establish ex situ conservation for this species. It is important to note that population densities of sifakas on sandstone soil are more than twice the population density found on limestone soils. This should enter into the conservation equation and protecting sandstone sites should be a priority.
