Distribution: Indochina: Thailand and Koh Samui off the east coast of peninsular Thailand (J. T. Marshall, Jr., 1977 a), Cambodia, C Laos (Smith et al., In Press), and Vietnam (Dang et al., 1994) in Indochina (including islands of Cham and Thô Chu off the coast of S Vietnam; Kuznetsov, 2000). Sunda Shelf: Malay Peninsula, Sumatra, Java, Borneo, Kangean Isl, and Bali. Nusa Tenggara (Lesser Sunda Isls): islands of Lombok, Sumbawa, Sangeang, Komodo, Rintja, Flores, Adonara, Lembata, Alor, Sumba, Timor, and Tanimbar. East of Indochina and the Sunda Shelf: Philippines (Cebu, Luzon, Mindoro, Negros, and Mindanao Isls; Heaney et al., 1998); Sulawesi (Musser and Holden, 1991); and one place and date of collection in New Guinea (Musser, 1973 b; Taylor et al., 1982). See Musser (1973 b) and Maryanto (2003) for details of range. Corbet and Hill (1992), followed by Helgen (2003 b), recorded the species from Seram in the Moluccas, but we cannot locate any specimens that would substantiate that occurrence, and Maryanto’s (2003) taxonomic revision of Indonesian populations does not include Seram within the distribution.

Habitat. Various open grassland areas and swampy grasslands. Today, the Ricefield Rat is found primarily in agricultural fields (rice specifically), grasslands, and plantations, being relatively commensal with humans. The species is rarely found in houses. It is usually associated with lowland habitats, but it does occur at higher elevations in some regions.

Movements, Home range and Social organization. Male Ricefield Rats usually live in solitary burrows; no large communal burrows have been reported. Reproduction and increases in density mainly occur when rice is being grown. Densities of 500 - 600 ind / ha have been recorded in fields in Indonesia. A significant drop in density occurs after harvesting. When traveling between burrows and feeding areas, regulartrails are used. After harvest, many Ricefield Rats shelter in piles of straw left in the field, and others move to nearby fields.
