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 Abies concolor (5-50% cover), Pinus ponderosa (5-50% cover), and sometimes Pseudotsuga menziesii (27% cover). The shrub layer is typified by Symphoricarpos mollis (11% cover), Holodiscus discolor (6% cover), and Rosa gymnocarpa (3% cover). Stands in the eastern Cascades have only snowberry (Symphoricarpos mollis and Symphoricarpos albus) covering 0-30%. Herbs are lacking in the Klamath-Siskiyou, but in the Cascades common species include Arnica sp. (0-30% cover), Poa wheeleri (0-20% cover), and Carex inops ssp. heliophila (0-10% cover). Fires maintain Pinus ponderosa while limiting Abies concolor. This community is warmer and drier than most Abies concolor associations.
