Assessment Information [top]

Red List Category & Criteria:	Vulnerable A4c ver 3.1
Year Published:	2008
Assessor/s:	Heaney, L. & Balete, D.
Reviewer/s:	Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Contributor/s:
Justification: This species is listed as Vulnerable due to an assumed population decline, estimated to be more than 30% over 10 years, based on a shrinkage in distribution due to habitat destruction and degradation. It is expected that this population's decline will continue as habitat loss is ongoing.

Geographic Range [top]

Range Description:	This species is endemic to the Philippines and occurs from sea level to 1,550 m on Camiguin (L. Heaney pers. comm.; Heaney and Tabaranza 1995), Leyte, and Mindanao (Bukidnon, Cotabato, and Davao del Norte provinces) which represent two biogeographic regions. It is known from scattered records in the central parts of its range in Mindanao but is likely to occur throughout eastern Mindanao since it also occurs on Leyte (L. Heaney pers. comm.).

Population [top]

Population:	The population status of the species is not very well known as it is very difficult to trap and there have been very few appropriate surveys for this species (L. Heaney pers. comm.). However, it has been found to be moderately common on Camiguin (Heaney et al. 2006).
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	The species inhabits lowland forest and tolerates some level of habitat disturbance. On Camiguin it has been found in disturbed agricultural land among secondary forest and disturbed montane forest (Heaney and Tabaranza 2006).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	There is significant deforestation in the lowlands, and much of this species habitat is gone.

There is significant deforestation in the lowlands, and much of this species habitat is gone.

Conservation Actions [top]

Conservation Actions:	More surveys using appropriate trapping techniques (with earthworms or drift fences) need to be undertaken at lower elevations to get a better sense of this species' population status. More research should also be carried out to determine if the species can persist in second growth forest.
