Name: Pseudotsuga menziesii - Tsuga heterophylla / Gaultheria shallon - Vaccinium parvifolium Forest
Reference: NatureServe Biotics 2019
Description: This Douglas-fir - western hemlock forest of California, Washington and Oregon has a canopy that is usually codominated by <i>Pseudotsuga menziesii</i> and <i>Tsuga heterophylla</i>, though in any one stand one or the other could be dominant. Occasionally <i>Pseudotsuga</i> is entirely absent. <i>Thuja plicata</i> is usually prominent to occasionally codominant. The well-developed shrub layer is dominated by <i>Gaultheria shallon</i>. Typically, no other shrubs are prominent, though <i>Acer circinatum</i> occasionally can be. <i>Vaccinium parvifolium</i> and <i>Mahonia nervosa</i> are usually present in small amounts. The herb layer is absent to rather sparse with <i>Linnaea borealis</i> the most frequent species. <i>Blechnum spicant</i> is usually absent, or if present, only in small amounts. In Washington, this association occurs on the western slopes of the Cascades and on the Olympic Peninsula. It is absent from the outer coastal strip and infrequent to rare on the western side of the Olympic Mountains. This association occupies relatively low to middle elevations and well-drained soils. These are moderately dry sites.
