CEGL005628 Abies amabilis - Tsuga mertensiana / Menziesia ferruginea Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Pacific Silver Fir - Mountain Hemlock / Rusty Menziesia Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: The canopy is typically codominated by Abies amabilis and Tsuga mertensiana. The latter has over 10% total cover and the former usually dominates tree regeneration. Tsuga heterophylla and Callitropsis nootkatensis are sometimes present to prominent. The well-developed shrub layer is usually codominated by Menziesia ferruginea and either Vaccinium membranaceum or Vaccinium alaskaense, or both. Vaccinium membranaceum is almost always present and Sorbus sitchensis is frequent. Vaccinium ovalifolium is occasionally prominent. The herb layer is variable in density and rather species-poor. At Mount Rainier, Erythronium montanum sometimes dominates a well-developed herb layer under the shrub layer. Rubus lasiococcus and Rubus pedatus are usually present. This association occurs at Mount Rainier and in the eastern portion of North Cascades at middle to high elevations, as well as in Oregon. Sites tend to be slopes with northern aspects or benches, and soils are relatively moist.
