Name: Abies grandis / Vaccinium membranaceum Rocky Mountain Forest Reference: Western Ecology Working Group of... Description: This forest association occurs within the maritime-influenced climatic regions of the northern Rocky Mountains of Idaho and is centered in the Idaho Batholith and Blue Mountains ecoregional sections. Stands are located on moist, north- to east-facing slopes and benches at 1370-1980 m (4500-6500 feet) elevation. Loam soils are derived from basalt and granitic parent materials. The association represents the coolest extreme of sites with potential for Abies grandis establishment. Pinus contorta, Pseudotsuga menziesii, and Picea engelmannii are predominant seral species. Vaccinium membranaceum forms a patchy medium shrub sward. Lonicera utahensis is usually present and often well-represented. Relatively constant forbs include Arnica cordifolia, Thalictrum occidentale, Carex rossii, Moehringia macrophylla, Chimaphila umbellata, Orthilia secunda, and Trillium ovatum. The association is similar to Abies grandis / Vaccinium membranaceum Forest (CEGL000290), which is described from the south-central Cascade Range and Blue, Ochoco, and Wallowa mountains. Abies grandis / Vaccinium membranaceum Rocky Mountain Forest (CEGL000289) is the easternmost manifestation of Abies grandis / Vaccinium membranaceum communities. The association is differentiated on the basis of the dominance in the Rocky Mountain form of Vaccinium membranaceum (= Vaccinium globulare).  Accession Code: VB.CC.20424.ABIESGRANDISVAC Plot-observations of this Community Concept: 0
