Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Samudio, R., Timm, R., Pino, J., Woodman, N. & Reid, F.
Reviewer(s): McKnight, M. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)
Justification:
Although its extent of occurrence is probably less than 10,000 km2, this species is listed as Least Concern in view of its presumed large and stable 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.

Population: It is fairly common (Reid 1997).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This species occurs in wet montane forest, forest edge, dense grass, and paramo.

This species favors cold environments (Reid 1997). It is terrestrial, traveling in runways under logs and among rocks or through dense vegetation. Almost entirely insectivorous in diet, it prefers larval beetles, which are probably located by smell. Little nest-building activity occurs in captivity, and nests have not been found in the wild. It appears to breed year-round; litters size is 2 to 4 young, averaging 2.7 (Reid 1997).
Systems: Terrestrial

Threats [top]

Major Threat(s): There are no major threats to this species, though in parts of its range it is adversely affected by agrochemicals, loss of grassland habitat (to development) and to some extent, deforestation.

Conservation Actions [top]

Conservation Actions: Much of its habitat occurs within protected areas.
