Name: Pinus ponderosa - Juniperus occidentalis / Artemisia tridentata - Purshia tridentata Woodland
Reference: Western Ecology Working Group of...
Description: This is a woodland association found in the Blue Mountains and eastern Cascades from Oregon and northern California. Stands include all aspects and slopes, with elevations ranging from 4500-6000 feet in elevation. Sites are on basalts, andesite or colluvium, with very stony or shallow soils. In the southern Cascades, these woodlands are often on pumice. They are codominated by Juniperus occidentalis and Pinus ponderosa. In the sampled plots, pine dominates the overstory, with between 5 and 50% cover, with juniper having between 1-20% cover in a lower tree layer. Tall shrubs, including Artemisia tridentata (ssp. tridentata, ssp. wyomingensis, and ssp. vaseyana all are reported from stands of this type), Purshia tridentata and Cercocarpus ledifolius are always present, between 1 and 60% cover. Generally, Purshia or Artemisia are codominant, although only one or the other can be present. Other shrubs include Ericameria nauseosa (= Chrysothamnus nauseosus), Amelanchier alnifolia, and Artemisia rigida.
