Name: Pseudotsuga menziesii - Arbutus menziesii / Gaultheria shallon Forest
Reference: Western Ecology Working Group of...
Description: This association occurs primarily at low elevations in British Columbia, Washington, and Oregon in the Georgia Basin, the Puget Lowland, and in low hills of the Klamath Mountains. It may also extend into northwestern California. This is typically a mixed evergreen needle-leaved-evergreen broad-leaved forest dominated by <i>Pseudotsuga menziesii</i> and <i>Arbutus menziesii</i>. The understory is dominated by the evergreen broad-leaved shrub <i>Gaultheria shallon</i>, very locally codominated by <i>Vaccinium ovatum</i>. The taller deciduous shrubs <i>Holodiscus discolor</i> or <i>Corylus cornuta</i> are often abundant as well. Other frequent species are <i>Polystichum munitum, Pteridium aquilinum, Mahonia nervosa</i>, and <i>Rubus ursinus</i>. Herbaceous species are typically found in small amounts. This association occurs on dry sites, either due to aspect and slope, or shallow soils. This association is distinguished from similar ones by >20% cover of <i>Arbutus menziesii</i> and >10% cover of <i>Gaultheria shallon</i>, combined with <10% cover of <i>Tsuga heterophylla, Thuja plicata</i>, and <i>Polystichum munitum</i>.
