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