Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(ii,iii) 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)
Although this species is not well known, the current extent of occurrence is estimated at less than 20,000 km², and the habitat within this range is fragmented and continues to decline as a result of ongoing threats. There is currently no evidence of hunting, persecution, or the effects of non-native carnivores, although there is a need to determine the extent of these threats, in light of which the species may require uplisting to Endangered.
Previously published Red List assessments:
2000 Vulnerable (VU)
1996 Vulnerable (VU)
1994 Insufficiently Known (K)
1990 Insufficiently Known (K)
1988 Insufficiently Known (K)
1986 Insufficiently Known (K)

Geographic Range [top]

Range Description: This little-known species is endemic to northeastern Madagascar. The species has been recorded in the Masoala Peninsula, Zahamena National Park, and Betampona Strict Nature Reserve. There are only four confirmed recent localities, including two individuals with aberrant coloration in reed beds of Lac Alaotra at around 800 m (J. Durbin pers. comm.). There were also historical records from the area surrounding Lac Alaotra. The known records in rainforest range in elevation from 200 to 650 m. The type locality is unknown. There are historical records from Mananara MAB Reserve (Albignac 1973). Despite substantial trapping efforts in eastern rainforest over the last 15 years above 600 m, the species has not been recorded in any new sites (S.M. Goodman pers. comm.).

Population [top]

Population: There is no information on the population status of this secretive species. The only locations where there have been recent multiple observations are Betampona Strict Nature Reserve (Britt and Virkaitis 2003) and Masoala National Park (F. Hawkins pers. comm.).
Current Population Trend: Unknown
Additional data:
Population severely fragmented: Yes

Habitat and Ecology [top]

Habitat and Ecology: It is a diurnal species that has been recorded from lowland tropical humid forest, and possibly from the reedbeds surrounding Lac Alaotra (J. Durbin pers. comm.). The animals rest in burrows or hollow trees during the night. Usually found singly or in pairs.The gestation period is about three months and there is a single young (Albignac 1973). This species is shy and sensitive to human disturbance.
Systems: Terrestrial

Threats [top]

Major Threat(s): It is threatened by deforestation of its habitat through conversion to cultivated land, selective logging and charcoal production. The lowland forest below 500 m is one of the most threatened habitats in Madagascar. There is no knowledge of hunting, persecution, or the effects of non-native carnivores, although it is certain that these occur within the species’ range.

Conservation Actions [top]

Conservation Actions: This species has been recorded from Masoala National Park, Zahamena National Park, and Betampona Strict Nature Reserve. Additional work is needed to determine the current status of the populations of this species across its range, as well as basic information on its ecology and natural history.
