|Reviewer(s):||McKnight, M. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)|
Listed as Least Concern in view of its wide distribution, presumed large population, occurrence in protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

|Population:||It can be uncommon in some parts of its range, however, in other places it may be common (Best 1995).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species is found primarily in oak and oak-pine forests (Best 1995).
In some localities it was observed during the early morning hours. Nests may be inside natural cavities of trees or built of leaves and sticks placed on branches of trees. Larvae and adult insects are common in the diet; peanuts, corn, oats, apples, peaches, mangos, plums, grapes, tomatoes, and anurans also are consumed. This species occasionally enters cornfields and can considerably damage ripening corn. Several females were recorded with embryos (2 to 4) in March, July, and August; two females on April were lactating; and a nest containing several small young was found in August in a hollow branch of a tree (Best 1995).
|Major Threat(s):||This species is threatened by deforestation and hunting (for food). It is estimated to have lost 13-23% of its population based upon habitat change over the past 15 years (C. de Granmont and A. Cuaron pers. comm.).|
|Conservation Actions:||There are no specific conservation measures in place for this species. The species is common in Cumbres de Monterey National Park.|
