|Reviewer(s):||McKnight, M. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)|
This species is listed as Least Concern in view of its wide distribution, presumed large population, tolerance of a broad range of habitats, occurrence in a number of protected areas, and because it does not appear to be under threat and is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
|Range Description:||This species occurs in the savannas from southeastern Costa Rica through Panama, Colombia, Venezuela, and the Guianas, to Brazil north of the Amazon River; including Trinidad and Tobago and smaller continental shelf islands adjacent to Panama and Venezuela (Musser and Carleton 2005).

|Population:||This rat is common, often abundant. It sometimes is a pest in agricultural areas (M. Aguilera pers. comm.).|
|Habitat and Ecology:||
This species is abundant in grassland, clearings, marshy areas, second growth, and agricultural areas (Martino and Aguilera 1993).
This species is nocturnal and terrestrial. Its diet includes seeds, fruit, and green plant material. This species makes short burrows in banks or under tree roots, leadings to nests made of grasses and plant down (Reid 1997). In Venezuela, breeding occurs year-round and litter size averages 4.1 (O’Connell 1982).
|Major Threat(s):||There does not appear to be any major threats to this species.|
|Conservation Actions:||It occurs in several protected areas (M. Aguillera pers. comm.).|
