CEGL000006 Abies amabilis / Polystichum munitum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Pacific Silver Fir / Western Swordfern Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: 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 Abies amabilis types. Soils are moderately well-drained and may be subirrigated. The canopy is dominated primarily by Tsuga heterophylla and secondarily by Abies amabilis. These two species usually codominate tree regeneration. Thuja plicata or Pseudotsuga menziesii can be prominent. The shrub layer is sparse to moderately dense, with Vaccinium alaskaense and Vaccinium parvifolium the most abundant species. Acer circinatum is sometimes prominent. A typically rich and diverse herb layer is characterized by the prominence to codominance of Polystichum munitum. Blechnum spicant and Tiarella trifoliata are usually present to prominent.
