This rat is listed as Near Threatened, because although it is considered abundant within its small range, its extent of occurrence is approximately 6,129 km² and there appears to be wide scale forest loss on Taliabu. The species is close to qualifying for Vulnerable under criterion B1. Further studies are needed to determine if this species can persist in modified habitats.

Geographic Range [top]

Range Description:This species is known only from Pulau Taliabu and adjacent Pulau Mangole in the Sula Archipelago (Indonesia), but is absent from Pulau Sanana, where only the introduced R. tanezumi and R. exulans are found (Flannery 1995, Musser and Carleton 2005). It occurs from the lowlands to possibly around 1,200 m.

Habitat and Ecology [top]

Habitat and Ecology:This rat is present in lowland tropical forest, and has been collected in secondary growth and coco plantations, although it is not known if it can persist in these modified habitat and it is possible that the localities may have been close to relatively undisturbed forest.

Threats [top]

Major Threat(s): It may be threatened by habitat loss through logging and conversion of land to agricultural use. Taliabu has experienced drastic habitat clearance in the last few decades, in particular, primary lowland forest (Rheindt 2010). Forest fires have also caused large-scale forest destruction above 750 m asl on Taliabu (Rheindt 2010).  It is also potentially threatened by competition by introduced Rattus species.

Conservation Actions [top]

Conservation Actions: It is not known if the species is present in any protected areas. Further research is needed into the response of this species to habitat disturbance.
