Name: Abies concolor - Pinus ponderosa / Symphoricarpos spp. Forest
Reference: Western Ecology Working Group of...
Description: This forest is found in southern Oregon's Klamath-Siskiyou region and eastern Cascades and may extend into adjacent California. Elevations are between 1300-2165 m (4260-7100 feet), on all aspects, and a variety of slopes (5-70%). Parent material is typically igneous but also occasionally serpentine overlain by gravelly or sandy mantles. The overstory is dominated by <i>Abies concolor</i> (5-50% cover), <i>Pinus ponderosa</i> (5-50% cover), and sometimes <i>Pseudotsuga menziesii</i> (27% cover). The shrub layer is typified by <i>Symphoricarpos mollis</i> (11% cover), <i>Holodiscus discolor</i> (6% cover), and <i>Rosa gymnocarpa</i> (3% cover). Stands in the eastern Cascades have only snowberry (<i>Symphoricarpos mollis</i> and <i>Symphoricarpos albus</i>) covering 0-30%. Herbs are lacking in the Klamath-Siskiyou, but in the Cascades common species include <i>Arnica</i> sp. (0-30% cover), <i>Poa wheeleri</i> (0-20% cover), and <i>Carex inops ssp. heliophila</i> (0-10% cover). Fires maintain <i>Pinus ponderosa</i> while limiting <i>Abies concolor</i>. This community is warmer and drier than most <i>Abies concolor</i> associations.
