Name: Populus balsamifera ssp. trichocarpa / Rhododendron occidentale Forest
Reference: Western Ecology Working Group of...
Description: This forest association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. This association is found at approximately 1220 m (4000 feet) elevation on valley floors adjacent to perennial streams. Slopes are gentle with a southerly aspect. Soils are permanently flooded and are sandy loams derived from granite. This forest forms an open canopy between 20-35 m in height. <i>Populus balsamifera ssp. trichocarpa</i> dominates the canopy along with <i>Alnus rhombifolia</i> in the canopy or subcanopy. Emergent coniferous species such as <i>Calocedrus decurrens</i> or <i>Pinus ponderosa</i> may contribute scant cover. <i>Rhododendron occidentale</i> is the most common shrub. Other common shrub associates may include <i>Salix lutea</i> and/or <i>Artemisia douglasiana</i>. Many graminoids are present; <i>Calamagrostis canadensis</i> provides the most cover, but the genus <i>Carex</i> has many representatives. Species may include <i>Carex pellita, Carex feta, Carex lenticularis, Carex amplifolia</i>, and/or <i>Carex vesicaria</i>.
