Name: Pseudotsuga menziesii - Tsuga heterophylla / Gaultheria shallon / Xerophyllum tenax Forest
Reference: NatureServe Biotics 2019
Description: The canopy is dominated by <i>Pseudotsuga menziesii</i> and/or <i>Tsuga heterophylla</i>. Both of these species are always present. <i>Thuja plicata</i> is occasionally present to prominent. The well-developed shrub layer is always dominated by <i>Gaultheria shallon</i>. <i>Mahonia nervosa</i> is usually present and often prominent. <i>Acer circinatum</i> often forms a prominent taller shrub layer often with <i>Vaccinium parvifolium</i>. The herb layer is dominated by <i>Xerophyllum tenax</i>, which always occupies over 5% cover. <i>Linnaea borealis</i> is frequent. This association occurs on the southeastern Olympic Peninsula, slopes of Mount Rainier and southern Cascades in Washington. Sites occupied are mid to upper slopes with shallow soils and mostly south to west aspects, or relatively flat with very coarse-textured glacial soils (latter only on Olympic Peninsula). Sites are located at low to especially middle elevations.
