Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Black Cottonwood / Western Azalea Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: 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. Populus balsamifera ssp. trichocarpa dominates the canopy along with Alnus rhombifolia in the canopy or subcanopy. Emergent coniferous species such as Calocedrus decurrens or Pinus ponderosa may contribute scant cover. Rhododendron occidentale is the most common shrub. Other common shrub associates may include Salix lutea and/or Artemisia douglasiana. Many graminoids are present; Calamagrostis canadensis provides the most cover, but the genus Carex has many representatives. Species may include Carex pellita, Carex feta, Carex lenticularis, Carex amplifolia, and/or Carex vesicaria.
