|Scientific Name:||Rattus montanus|
|Species Authority:||Phillips, 1932|
|Taxonomic Notes:||Ellerman (1961) included this species under subgenus Rattus Fischer, 1803. Corbet and Hill (1992) remark that “it has been suggested that this name might be based upon a ‘sample of extremely large Rattus rattus kelaarti males’ (McKay, 1984) but the teeth are very distinctive and preclude that possibility, a conclusion supported by Musser (1986)”. Phillips (1980) gives a detailed account of this species.|
|Red List Category & Criteria:||Endangered B1ab(iii)+2ab(iii) ver 3.1|

Listed as Endangered, because its extent of occurrence of less than 5,000 km² and its area of occupancy is less than 500 km², its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat.
|Range Description:||This species is endemic to Sri Lanka in Central and Uva provinces, restrcited to four highly fragmented locations (knuckles, Horton Plains, Nuwara Eliya and Ohiya) in the central highlands (Phillips 1980; Molur et al. 2005; D. Wickramasinghe in litt. 2005, W.I.L.D.P.T.S. de A. Goonatilake in litt. 2005). It occurs at elevations from 1,320 to 2,310 m asl (Molur et al. 2005).|

|Population:||There is no information available on the population abundance of this species (Molur et al. 2005).|
|Habitat and Ecology:||It is a diurnal or crepuscular, terrestrial species. It occurs in tropical evergreen montane forest and wet grasslands (Molur et al. 2005).|
|Major Threat(s):||Habitat loss and degradation due to expansion of agriculture, fire and clear-cutting of forests have been observed to be the major threats for this species (Molur et al. 2005).|
|Conservation Actions:||The species is not protected by any legislation. It has been recorded from Horton Plains National Park and Knuckles Forest Reserve. General field surveys, research into the natural history and monitoring of populations are recommended for this species (Molur et al. 2005).|
