Threats [top]

Major Threat(s): This species is threatened by competition, and possibly pathogen and parasite transmission, from the introduced species, Rattus rattus.

It is also hunted by local people for food and for its teeth, with the pelt taken as a by-product of this hunting, but this is not viewed as a major threat. It is adversely affected in parts of its range by conversion of forest habitat to cultivated land.

Conservation Actions [top]

Conservation Actions: It has been recorded from some protected areas. It is legally hunted in some of the protected areas. Further studies are needed into the taxonomy of this species.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
