Ecology & Habitat

Habitat

Mostly in rock slides, talus slopes, and among large boulders, usually near meadows and patches of veg. Usually above timberline but occasionally in forested valleys and near sea level (MacDonald and Jones 1987).

Ecology

May defend home territory about 30 m in diameter (700 sq m). Population density estimated at 6.4-7.2/ha. Ermine (MUSTELA ERMINEA) apparently is the most important predator (MacDonald and Jones 1987).

Reproduction

Breeding apparently peaks May-early June. Gestation lasts about 30 days. Produces 1 or 2 litters of 2-6 young, May-September. Young reach adult size in 40-50 days. Females can breed and produce young at about 1 year of age (MacDonald and Jones 1987).
