Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Heaney, L. & Balete, D.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
Listed as Least Concern as much of its range is very steep, occurring at high elevations and is therefore not likely to be converted to agriculture.

Geographic Range [top]

Range Description: This species is endemic to the Philippines and restricted to the Central Cordillera in northern Luzon. This species is known only from four widely scattered localities ranging in elevation from 1,800-2,500 m (L. Heaney pers. comm.). Records are from high elevation forest in Benguet province and in Balbalasang, Kalinga province (Heaney et al. 2004).

Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: The species occurs in thick vegetation in high elevation transitional montane-mossy and mossy forest at 1,800 to 2,500 m (Sanborn 1952; Thomas 1898; Heaney et al. 2004). It is also found in mosaic habitats created by landslides but is not tolerant to significant forest disturbance. It feeds on earthworms (L. Heaney pers. comm.).
Systems: Terrestrial

Threats [top]

Major Threat(s): There are no major threats to this species as it occurs on high elevation montane areas where it is cold, wet and steep. There is some localized threat such as high altitude vegetable farming, but this takes place only in a small portion of their range.

Conservation Actions [top]

Conservation Actions: This species used to occur on Mt. Data National Park, but does not anymore. It does, however, occur in a number of other protected areas (L. Heaney pers. comm.).
