| Juniper trees are the main source of food, water, and shelter for Stephen's Woodrat. Like Red Tree Voles, which feed mostly on Douglas-fir, the Woodrats are able to feed primarily on conifer leaves, which contain chemical compounds - tannins and terepenoids - that interfere with digestion in most mammals. Stephen's Woodrats usually nest at or near the base of junipers, in habitats that include rocks and crevices. Fossils and studies of preserved middens indicate that these Woodrats have been associated with junipers for at least 15,000 years. Females of this species can reproduce when they are nine months old, and can produce offspring five times a year. Usually only one young is born at a time, but occasionally there are twins.
Males are larger than females.
