Vandeleuria nolthenii


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Vandeleuria nolthenii
Species Authority: Phillips, 1929
Common Name(s):
English Sri Lankan Highland Tree Mouse, Nolthenius's Long-tailed Climbing Mouse
Vandeleuria nilagirica Phillips, 1929 subspecies nolthenii
Vandeleuria oleracea (Phillips, 1929) subspecies nolthenii
Taxonomic Notes: Ellerman (1961) and, Agrawal and Chakraborty (1980) included this form under Vandeleuria oleracea (Bennett, 1832). Corbet and Hill (1992) quoting Musser (1979) treated it as a species by itself separate from Vandeluria oleracea (Bennett, 1832), a trend also accepted by Musser and Carleton (1993) by virtue of it’s distinct montane distribution, pelage colouration, external and cranial traits.

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): de A. Goonatilake, W.I.L.D.P.T.S., Nameer, P.O. & Molur, S.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Listed as Endangered, because its extent of occurrence of less than 5,000 km² and its area of occupancy is less than 500 km², its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat.
1996 Vulnerable

Geographic Range [top]

Range Description: This species is endemic to the central highlands of Sri Lanka, recorded from a few fragmented locations in the Central Province occuring at altitiudes of 1,320 to 2,130 m asl (Molur et al. 2005; Philips 1980; W.I.L.D.P.T.S. de A. Goonatilake in litt. 2005). Based on available montane habitats the extent of occurrence and area of occupancy have been estimated as less than 5,000 km². and less than 500 km², respectively (Molur et al. 2005).

Threats [top]

Major Threat(s): Habitat loss and degradation due to expansion of agricultural activities and clear-cutting of forest have been observed to be the major threats for this species in Sri Lanka (Molur et al. 2005; W.I.L.D.P.T.S. de A. Goonatilake in litt. 2005).

Conservation Actions [top]

Conservation Actions: The species is not protected by any legislation. It is present in the Knuckles Forest Reserve (Molur et al. 2005, W.I.L.D.P.T.S. de A. Goonatilake in litt. 2005). Survey, taxonomic, ecological and life history studies, and monitoring are recommended for this species (Molur et al. 2005).
