Name: Tsuga heterophylla / Polystichum munitum - Oxalis oregana Forest
Reference: NatureServe Biotics 2019
Description: This western hemlock forest of California, Oregon and Washington has a canopy that is usually dominated by <i>Tsuga heterophylla</i>. <i>Pseudotsuga menziesii</i> is occasionally present to codominant. The shrub layer is typically sparse to moderately dense. <i>Vaccinium alaskaense, Vaccinium parvifolium</i>, and <i>Rubus spectabilis</i> are usually present. The latter is sometimes prominent. <i>Acer circinatum</i> is occasionally prominent to codominant. The well-developed herb layer is codominated by <i>Polystichum munitum</i> and <i>Oxalis oregana</i> (or occasionally just by the latter). <i>Blechnum spicant</i> is almost always present and occasionally prominent. <i>Tiarella trifoliata</i> is often present. This association occurs at low elevations on valley bottoms, lower slopes and, less commonly, mid slopes. Soils are deep, well-drained, and moist.
