|Population:||This species is abundant. Depending on the season, population densities may vary from less than one to 15 per acre (Yerger 1953), and sometimes up to 30 per acre.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It prefers deciduous woodlands with ample cover, such as brush piles or logs, rocky forested slopes, ravines. Also found in brushlands and hedgerows. Commonly climbs trees and shrubs. Burrows often open at edge or rock, near base of tree, or under the edge of a building. Nest is generally constructed below ground in an extensive burrow system.|
Breeding period is from mid-March to early April. A second breeding period occurs from mid-July to mid-August involving young of the previous year. Gestation lasts 31 days. Litter size is 4-15 (3-5 most often). One to two litters per year. Commonly lives 2-3 years, sometimes 5-6 years.
Home range is less than one hectare, typically 0.08-0.60 ha, largest in early summer and early fall; core area of home range is defended against conspecific neighbours; largest home ranges are those of breeding males; low water availability may result in increased home range size. Individuals may make long movements outside their usual range; non dispersing individuals have lifetime home range lengths of up to at least 0.5 km, and dispersal movements may extend to at least 0.9 km (Roberts 1976).
This species utilizes a wide variety of seeds, fruits, and nuts, some mushrooms and insects. Active during the day. In winter, becomes torpid, with frequent arousals.
|Major Threat(s):||There are no major threats to this species.|
|Conservation Actions:||The range of this species includes several protected areas.|
