Rocky Mountain juniper (Juniperus scopulorum) is one of 13 junipers native to North America. It is similar to eastern redcedar (Juniperus virginiana) but requires 2 years for seed maturity, compared to 1 year for its eastern relative. Other common names for the typical variety include Rocky Mountain redcedar, redcedar, western redcedar, river juniper, cedro rojo, and sabino (23,42,49). Rocky Mountain juniper varies in size from a shrub to a small tree. The largest specimen grows in the Cache National Forest in Utah. It measures 198 cm (78 in) in d.b.h. but is only 11 m (36 ft) tall. Much information is available about Rocky Mountain juniper as a member of a variety of habitat associations; however what is known about the silvics of the species is more limited (41).
