Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(i,ii,iii,v); C2a(ii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30

Reviewer(s): Hoffmann, M. (Global Mammal Assessment Team) & Duckworth, J.W. (Small Carnivore Red List Authority)
Listed as Endangered as the range of this species is less than 500 km², effectively representing a single location, and there is a continuing decline in the extent of occurrence and habitat quality as a result of habitat degradation taking place at the edge of its restricted range (compounded by predation by non-native predators). The total population is estimated at 2,650 and 3,540 individuals (including immatures), with all individuals confined to the area around Lac Tsimanampetsotsa.
2000 Endangered
1996 Endangered
1994 Rare (Groombridge 1994)
1990 Insufficiently Known (IUCN 1990)
1988 Insufficiently Known (IUCN Conservation Monitoring Centre 1988)

Geographic Range [top]

Range Description: This species is restricted to the Lac Tsimanampetsotsa region of south-western Madagascar. It has been recorded from the edge of the Mahafaly Plateau north and further south to near the Linta River (Goodman 2003; Mahazotahy et al. 2006). The altitudinal range is 35-145 m (Mahazotahy et al. 2006). A recent model calculated the range at 442 km² (Mahazotahy et al. 2006).

Population [top]

Population: Described only in 1986, this species appears to be locally common in pristine forest (Goodman 2003). The population size of this species is estimated at between 2650 and 3540 individuals (including juveniles) (Mahazotahy et al. 2006).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This nocturnal, terrestrial species is found in dry spiny tropical forest and shrubland and at the edge of the forest in areas disturbed by cattle grazing. Animals spend daylight hours asleep in burrows or holes that are prevalent in the fissured limestone substrate characteristic of its habitat. While little is known about reproduction in this species, it appears to breed continously (Goodman 2003).
Systems: Terrestrial

Threats [top]

Major Threat(s): This species has a limited range, and its habitat is threatened by livestock grazing and clearance for maize cultivation. The western part of the area in which it is found is reasonably inhospitable to human encroachment (Goodman 2003). It is probably at risk of predation by non-native carnivores, especially dogs.

Conservation Actions [top]

Conservation Actions: The only protected area within range is Tsimanampetsotsa National Park. Further studies are needed into the ecology of this species, as well as the extent of threats.
