Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Rodentia Sciuridae

Scientific Name: Callosciurus inornatus
Species Authority: (Gray, 1867)
Common Name(s):
English Inornate Squirrel
Taxonomic Notes: This species was previously considered a subspecies of Callosciurus pygerythrus following Ellerman and Morrison-Scott (1951), but separated on the basis pelage characteristics (Corbet and Hill 1992). This confusion led to the listing of Lao PDR and Viet Nam in the stated distribution of C. pygerythrus by several treatments. C. caniceps is likely a more closely related taxa (Corbet and Hill 1992), whose allopatric distribution is separated by the Mekong River (Moore and Tate 1965).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Duckworth, J.W. & Timmins, R.J.
Reviewer(s): Smith, A.T. & Johnston, C.H. (Global Mammal Assessment Team)
This species is listed as Least Concern because of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Population [top]

Population:This species is relatively common and abundant in Viet Nam (Timmins and Lunde pers. comm.). In Lao PDR, it is found sporadically and at low density in large forest blocks (Evans et al. 2000), but large populations occur in secondary forest and scrub in north Lao PDR (Duckworth and Robichaud 2005) and probably central Lao PDR (Duckworth pers. comm.).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species has been found in secondary and disturbed forest in Lao PDR (Evans et al. 2000). It has also been found in both wet and dry evergreen forest (Evans et al. 2000). Observations in Viet Nam and Lao PDR suggest that this is actually an edge and disturbed forest species (Lunde, Timmins, Duckworth pers. comm.).

Threats [top]

Major Threat(s): There are no major threats to this species. This species is hunted in Lao PDR (Evans et al. 2000). Large populations persist close to villages in Phongsali, and there is no evidence that hunting is a threat (Duckworth pers. comm.). Habitat loss may not be a threat as the species may actually benefit from the shifting cultivation system (Duckworth pers. comm.).

Conservation Actions [top]

Conservation Actions: This species occurs in many protected areas in Lao PDR (Duckworth et al. 1999). It probably occurs in protected areas in China. It has been regionally Red Listed, in China, as Vulnerable A1cd; B1ab(iii) (Wang and Xie 2004).
