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 they represent two different series [ see Mountain juniper series]. There is some overlap in s. ModP and n. TraSN, where Vasek & Thorne (1977a) report that mountain juniper tends to occur on ridges and escarpments, while western juniper occurs in valleys. Occasional western juniper trees may gr w in stands of other series [ see Jeffrey pine series, Oregon white oak series, Ponderosa pine series, Washoe pine series].
Plot based descriptions:Vasek & Thorne (1977a) report density for a stand in Siskiyou Co., Keeler-Wolf (1984d) in Keeler-Wolf (1990e) describes a stand at Devil's Garden RNA in Modoc Co. ModP.
