Name: Abies amabilis / Polystichum munitum Forest
Reference: NatureServe Biotics 2019
Description: This association occurs on the western slopes of the Cascades and on the southern, eastern, and northern sides of the Olympic Mountains at low to moderate elevations (150-915 m (500-3000 feet)). It is found on relatively moist sites, often lower slopes, that have lower snowpack than average for most <i>Abies amabilis</i> types. Soils are moderately well-drained and may be subirrigated. The canopy is dominated primarily by <i>Tsuga heterophylla</i> and secondarily by <i>Abies amabilis</i>. These two species usually codominate tree regeneration. <i>Thuja plicata</i> or <i>Pseudotsuga menziesii</i> can be prominent. The shrub layer is sparse to moderately dense, with <i>Vaccinium alaskaense</i> and <i>Vaccinium parvifolium</i> the most abundant species. <i>Acer circinatum</i> is sometimes prominent. A typically rich and diverse herb layer is characterized by the prominence to codominance of <i>Polystichum munitum</i>. <i>Blechnum spicant</i> and <i>Tiarella trifoliata</i> are usually present to prominent.
