Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Francis, C., Hutson, A.M., Kingston, T. & Bumrungsri, S.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority), Chanson, J. & Chiozza, F. (Global Mammal Assessment Team)
Listed as Data Deficient as there is little information available on range, population status and threats for this species. It may be potentially declining due to loss of habitat, and is therefore a priority for survey work. The taxonomic status of this species needs to be confirmed.
Previously published Red List assessments:
1996 Data Deficient (DD)
1990 Rare (R)
1988 Rare (R)

Population [top]

Population: The abundance and population size of this species are not known. The species has a distinct morphology, and is unlikely to have been misidentified.
Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: This is a poorly known species. It seems to be associated with small streams (so probably somewhat dependent on water) and the understorey of rainforest. Resistance to human disturbance is unknown but it has been found in disturbed old growth forest in Thailand at an altitude of 100-200 m asl (Bumrungsri et al., 2006). It probably feeds outside of fragmented forests (S. Bumrungsri pers. comm.). All of the known records are from below 500 m asl.
Systems: Terrestrial

Threats [top]

Major Threat(s): Major threats to this species are not known, but habitat loss would be a likely threat to the species.

Conservation Actions [top]

Conservation Actions: It is known from Pulau Weh Recreation Park and Temenggor Forest Reserve, though the extent of protection offered by these areas is minimal. It is also found in Khuan Kaowang Forest Park in Thailand but this is a very small park. There is a need to determine the distributional limits and population status of the species, as well as potential threats and tolerance to human disturbance.
