Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Least Concern in view of its wide distribution, presumed large population, it occurs in protected areas and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
Previously published Red List assessments:
1996 Lower Risk/least concern (LR/lc)

Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: Species occurs from sea level to 800 m asl in wet evergreen forests (Lara et al. 2005), and in Rio de Janeiro State up to 900 m (Geise pers. comm.). In southeastern Brazil the species occurs mainly in dense rainforest.
Systems: Terrestrial

Threats [top]

Major Threat(s): The Atlantic Forest habitat is declining; however, this is not a major threat to this species (Geise pers. comm.).

Conservation Actions [top]

Conservation Actions: The species occurs in protected areas throughout its range (Geise pers. comm.). More taxonomic studies are required for the Akodon cursor complex. At present the only method of identifying species is using karyotyping (2n=14,15,16) (Fagundes et al., 1998).
