Name: Picea pungens / Betula occidentalis Woodland Reference: Western Ecology Working Group of... Description: This association is known from Colorado and possibly northern New Mexico. It is a cool, moist riparian woodland occurring in deep, narrow canyons in the foothills and at lower montane elevations of 2200-2700 m. Betula occidentalis forms a thick band in deep, subirrigated soils along narrow floodplains, streambanks and terraces, with branches overhanging the stream. Mature Picea pungens dominates the canopy (10-60% cover), though Populus tremuloides may be present as well. Betula occidentalis is always present in the shrub understory (20-40% cover), often joined by Alnus incana. Other shrubs include Salix exigua, Salix bebbiana, and Cornus sericea. Equisetum arvense is always present in the sparse or dense herbaceous layer. Common associates may include forbs such as Rudbeckia laciniata, Heracleum sphondylium, Fragaria virginiana, Mertensia ciliata, and the graminoid Calamagrostis canadensis.  Accession Code: VB.CC.26876.PICEAPUNGENSBET Plot-observations of this Community Concept: 0
