CEGL005635 Abies lasiocarpa / Rhododendron albiflorum / Rubus lasiococcus Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Subalpine Fir / Cascade Azalea / Rough-fruit Berry Forest

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: The canopy is dominated by Abies lasiocarpa with Callitropsis nootkatensis as a frequent codominant. Pinus contorta and Pseudotsuga menziesii have been recorded as codominants outside the parks. Abies lasiocarpa usually dominates tree regeneration and always has over 10% total cover. The moderate to dense shrub layer is dominated by Rhododendron albiflorum, with Vaccinium membranaceum usually present and occasionally codominant. Paxistima myrsinites is very frequent. The herb layer is sparse to moderately dense and is usually codominated by Rubus lasiococcus. Xerophyllum tenax occasionally codominates. This association occurs in the northeastern Olympics and in the Cascades, including northeastern Mount Rainier. This forest or woodland association occurs at high elevations (1400-1820 m [4600-6000 feet]). Sites are usually near avalanche chutes or on slopes with northwestern to eastern aspects with well-drained, shallow soils.
