Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(ii,iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Bates, P. & Francis, C.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority), Chanson, J. & Chiozza, F. (Global Mammal Assessment Team)
Listed as Vulnerable as the extent of occurrence is likely to be under 20,000 km². Surveys to the northwest, northeast and south of the two known localities have failed to find additional colonies, and it is not likely to have been overlooked in collections as it is a very distinctive species. There is an ongoing decline in the quality of the species' habitat.

Geographic Range [top]

Range Description:The species has been collected only in a small area at the center of Phou Khao Khouay National Biodiversity Conservation Area, Saisombun Special Area, where it appeared to be relatively common, and near Ban Nampe, about 11 km north east of Vang Vieng, Vang Vieng District, Vientiane Province, all in central Lao PDR (Guillén-Servent and Francis 2006).

Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:These bats have been captured in patches of intact and disturbed evergreen forest. In Vang Vieng there were large limestone outcrops with caves in the vicinity. Capture sites in Phou Khao Khouay were not near limestone outcrops or large caves, but the roost sites are not known.

Threats [top]

Major Threat(s): Habitat loss is a possible threat to this species as Phou Khao Khouay National Biodiversity Conservation Area is not well managed. One of the locations is affected by deforestation, road work and building associated with the development of the large Tad Leuk dam project (Guillén-Servent and Francis 2006).The type locality has been flooded for the dam (C. Francis pers. comm.).
