|Scientific Name:||Leopoldamys siporanus (Thomas, 1895)|
|Red List Category & Criteria:||Vulnerable B1ab(ii,iii) ver 3.1|
|Assessor(s):||Clayton, E. & Kennerley, R.|
|Contributor(s):||Musser, G., Lunde, D.P., Aplin, K. & Ruedas, L.|
Listed as Vulnerable because its extent of occurrence is 13,317 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its forest habitat.
|Previously published Red List assessments:|
|Range Description:||This species is endemic to the Mentawai Archipelago, Indonesia (Musser and Carleton 2005). It is found on the islands of North Pagai, South Pagai, Sipora, and Siberut (Musser and Newcomb 1983).|

|Population:||It was formerly common, but the population status is now unclear.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is an arboreal species that needs large trees in tropical lowland rain forest. It seems probable that only small patches of suitable habitat remain on these islands.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||Use and trade information for Leopoldamys siporanus is missing.|
|Major Threat(s):||The habitat of this species has been extensively deforested through extraction of timber and firewood and conversion to agricultural land; much of the area is now mixed fruit plantations.|
|Conservation Actions:||It is possibly present within Siberut National Park, however, about 40% of suitable habitat at this site has been disturbed (A. Suyanto pers. comm.). Further surveys are needed to determine the current status of this species.|
