Justification:

There is a suspected population reduction of ≥50% in this species over a three generation period (estimating the generation length to be 7 years). This time period includes both the past and the future. Causes of this reduction (which have not ceased) include continuing decline in area, extent and quality of habitat, and exploitation through unsustainable levels of hunting. A population reduction of ≥50% is also suspected to be met in the future (over a three generation time period of 21 years) due to the same causes.

Geographic Range [top]

Range Description: This species is found in the dry deciduous forests of western Madagascar. Populations range from north of the Betsiboka River to the Bay of Loza and the Mahajamba River. Further study is needed north of Ankarafantsika National Park to determine the northern extent of the range.

Population [top]

Population: This species has been studied in the dry deciduous forests in and around the Ankarafantsika National Park, where it has been reported at an approximate density of 60 individuals/km² (Warren and Crompton 1997). A recent genetic and demographic study showed signs of a demographic collapse of about two orders of magnitude in the L. edwardsi population in two sites. Population numbers are in decline due to habitat loss, and the species has already disappeared from several larger fragments (Mittermeier et al. 2008 and references therein).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology:

This species occurs in tropical dry deciduous lowland forest (up to 450 m above sea level). Leaves are a dietary mainstay  and make up 70–100% of the diet. Small amounts of fruits, flowers, and fleshy seeds are also eaten. This species eats lower quality leaves at Ankarafantsika than at other field sites, a difference that appears to be due to food competition with Avahi. L. edwardsi eats older leaves, and even the leaves that are dead or dying of Tabernaemontana modesta (Apocynaceae). Home ranges appear to be about one ha, and are vigorously defended with loud vocalisations and displays of branch-shaking. Several individuals can be found sleeping in the same shelter during the day, but they tend to be solitary foragers during the night (Mittermeier et al. 2008, and references therein). Infanticide has been reported in this species.

Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is hunted for food.

Threats [top]

Major Threat(s): The major threat to this species is habitat loss due to fires set to create new pasture for livestock, and it is also hunted for food in some areas.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix I of CITES. It is currently known to occur in Ankarafantsika National Park.
