Overview

Distribution

Range Description

This species is endemic to montane Borneo where it is restricted to altitudes above 900 m (Payne et al. 1998) in Malaysian northern Borneo, including the mountains of north-eastern Sarawak and Mts. Kinabalu and Trus Madi in Sabah (Helgen 2005). Recorded from 1,200 m to elevations of 3,350 m (Corbet and Hill 1992).

Justification
This species does not appear to have been recorded since the early 1970s. A primarily montane species, it has probably undergone some declines due to loss of habitat, particularly at lower elevations, but the absence of any recent records hinders any reliable assessment of their status. This species is a priority for further survey work, pending which it may warrant listing in Near Threatened or higher.

Population

Population
This species has not been recorded since the early 1970s. Between 1989 to 1991, three sessions of trappings at the area (Sinsuran Ridge, Sabah) where the animal was last caught in the early 1970s, failed to capture the animal (K.H. Han pers. comm.).

Bornean smooth-tailed treeshrew

The Bornean smooth-tailed treeshrew (Dendrogale melanura) is a species of treeshrew in the Tupaiidae family. It is endemic to Malaysia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.[2]

Description[edit]

Head and body length is 5 in (13 cm), with tail length 4.5 in (11 cm). The body mass is about 1.5 oz (43 g). Upper parts of the small body are dark brown, while the under parts are orange-buff with gray bases, and shiny black with reddish streaking along the sides. It has a short snout, with large ear flaps. Prominent orange-brown rings exist around the eyes, with weakly marked facial streaks present on both side of the face, extending from the snout to ears. No shoulder streaks are present. The claws are notably sharp. The thin tail is covered with fine, smooth hair, with darkening towards the tip.[3] D. m. melanura has darker colour above and more reddish below than D. m. baluensis.[4]

Habitat[edit]

D. melanura is a terrestrial species. They are diurnal and predominantly arboreal. Live in evergreen rainforest, which active in mossy trees and on rocky boulders in submontane and montane pristine forest. This species seems to feed predominantly on insects.[4]

Distribution[edit]

The species is endemic to Borneo, restricted in the mountains of the north-west above 900m, including the mountain of north-eastern Sarawak, Gunung Kinabalu, and Gunung Trus Madi in Sabah. D. m. melanura is recorded from Gunung Dulit, Gunung Mulu, and the Kelabit uplands in northern Sarawak, and from the Sabah-Sarawak border. Meanwhile, D. m. baluensis is recorded from Gunung Kinabalu and Gunung Trus Madi in Sabah.[4]

Threats and Conservation[edit]

This species is listed as data deficient because it has not recorded since the early 1970s. The major threats for this species are loss of habitat due to the agricultural expansion and conversion of land to non-tree plantations at lower elevations. This species may warrant listing in Near Threatened or higher. The conservation actions only occur at Crocker Range National Park, Sabah, Malaysia.[2]
