(Desmarest, 1822)

Common Name/s:

–

Prevost's Squirrel

Taxonomic Notes:

There are at least five subspecies which differ greatly in pelage: including C. p. pluto in Sabah; C. p. caroli in southern Sarawak; C. p. atricapillus in central Sarawak; and C. p. borneensis in central Borneo (Payne et al. 2005).

Assessment Information [top]

Red List Category & Criteria:

Least Concern ver 3.1

Year Published:

2008

Assessor/s:

Duckworth, J.W. & Hedges, S.

Reviewer/s:

Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)

Justification:
This species is listed as Least Concern in because of it is common and widespread, occurring in a number of protected areas, it is tolerant 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.

Lower Risk/least concern

Geographic Range [top]

Range Description:	This species is widespread in the southern part of Thailand, throughout Malaysia, Sumatra and Borneo, and on many smaller islands of Southeast Asia and Peninsular Malaysia (Corbett and Hill 1992; Oshida et al. 2001). Also found in northern Sulawesi where it has been introduced Musser (1987).
Countries:	Native: Brunei Darussalam; Indonesia (Kalimantan, Sumatera); Malaysia; Thailand

Population [top]

Population:	This species was the second most abundant of its genus found in a survey conducted by Saiful and Nordin (2004) in Peninsular Malaysia (Weng River sub-catchment), with a denisty of 3.29 ± 1.54 individuals/km². In general, this species is found at low densities in unlogged forest in Malayasia: in Danum Valley, Sabah, Norhayati (2001) found 7.3 individuals/km², while Zainuddin et al. (1996) found 2.98 individuals/km² in Nanga Gaat, Sarawak. In general, throughout its range it is fairly common (Han pers. comm.) and stable.
Population Trend:	Decreasing

Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	This is a diurnal and arboreal species (Saiful and Nordin 2004), descending only occasionally to ground to forage (Han pers. comm.). This species can tolerate secondary forest, and often enters fruit orchards (Han pers. comm.). This species is found in the dense rainforests of the southern Thai peninsula, eating mostly fruit, but also some arthropods, and is considered a pest of oil palm and coconut plantations (Lekagul and McNeely 1988).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	The remaining habitat of this lowland species is very small. A substantial part of its native range has been replaced by plantations. In parts of Sarawak it is very heavily hunted for pets (Giman and Han pers. comm.).

Conservation Actions [top]

Conservation Actions:	It occurs in many protected areas. Saiful and Nordin (2004) state the need for further comparative study on this species' abundance, density and distribution and its relationship to forest structure or habitat quality, spatially and temporally, in hill dipterocarp forest of Malaysia.
