Name: Pinus contorta var. contorta - Pseudotsuga menziesii / Gaultheria shallon Forest
Reference: NatureServe Biotics 2019
Description: This association occurs in a wide range of environments in the Puget Lowlands, and the Olympic Mountains and North Cascade Range. Most locations are less than 850 m (2800 feet) elevation. Sites vary from flat terrain to steep slopes on variable aspects. These sites are dry to moderately dry and appear to have relatively nutrient-poor soil. This type occurs on gravelly, sandy loam outwash deposits, glacial till, and sedimentary residuum. Soil depth can be quite shallow. <i>Pinus contorta</i> usually dominates the tree layer with <i>Pseudotsuga menziesii</i> typically prominent to codominant. <i>Pinus monticola</i> is often present and can be prominent in the canopy. <i>Tsuga heterophylla</i> is usually present but with low abundance. The understory is a dense layer of <i>Gaultheria shallon</i> often with scattered <i>Vaccinium parvifolium</i>. <i>Vaccinium ovatum</i> is a common member of Puget Lowland representatives of this association. <i>Pteridium aquilinum, Mahonia nervosa, Gaultheria ovatifolia</i>, and <i>Pyrola picta</i> are frequent species in the typically depauperate ground cover. The lichen <i>Cladonia bellidiflora</i> occurs in most plots.
