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, 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.

Habitat and Ecology [top]

Habitat and Ecology: This species is found at forest edge or among brush and pastured in cold, wet montane regions. It favors more open habitats than other harvest mice; it is fairly common in coniferous forest, but rare in mature, broadleaf forest (Reid 1997). Does well in secondary forest.

This mouse is mainly terrestrial and is usually trapped on the ground; although it can climb. A round nest of grass was fond under a log in a coffee field in Nicaragua (Jones and Genoways 1970 in Reid 1997). Breeding may occur year-round, and litter size is 3 to 5 young (Anderson and Jones 1960 in Reid 1997).
Systems: Terrestrial
