Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-05-09

This species is listed as Least Concern in view of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance of a degree of habitat modification, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Habitat and Ecology [top]

Habitat and Ecology:This mouse is terrestrial, and mostly nocturnal. It probably feeds on insects, seeds, and vegetation. It nests in burrows and travels in tunnels under leaf litter. It is found in evergreen forest, and in montane habitats, grassy areas, especially with tall grass, young second growth, gardens, and clearings. Reproduction is between July and August in southern Peru, with litter size from two to seven (Patton 2015).
Generation Length (years):1-2
