Reference:Mountain juniper range in CA (Griffin & Critchfield 1972); silvics (Dealy 1990). Barbour (1988), Paysen et al. (1980), Thorne (1982), Vasek & Thorne (1977).
Comments:There are taxonomic and ecological challenges involved with Juniperus occidentalis. The species has two subspecies, western juniper ( J. o. ssp. occidentalis) and mountain juniper ( J. o. ssp. australis ). The two subspecies have generally different ranges and ecology, so the two are segregated into two series [see Western juniper series]. There is some overlap in s. ModP and n. TraSN. Vasek & Thorne (1977) report that mountain juniper tends to occupy ridges and escarpments, while western juniper occupies the valleys.
Plot based descriptions:Keeler-Wolf (1974) describes stands for Soldier Ridge in Yolla Bolly Mountains m-NorCo; Potter (1994) defines two regional associations in m-SN, su-SN; Vasek & Thorne (1977) report density and cover for a stand in Lassen Co. n. TraSN.
Series Association:Potter (1994): Mountain juniper association [as Western juniper association], Mountain juniper/big sagebrush association [as Western juniper/big sagebrush association].
