CEGL005301 Cornus sericea Pacific Shrub Swamp
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Red-osier Dogwood Pacific Shrub Swamp
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This riparian tall shrubland is widespread in the Columbia Basin, the Intermountain Basin, and in the Rocky Mountains, and is discontinuously scattered in sheltered areas of the Colorado Plateau. It often forms continuous, narrow bands along streambanks, benches and bars, as well as in slot canyons. Many stands are located on nearly level, frequently flooded banks, in burns in steep avalanche chutes, or otherwise experience periodic disturbance. It also can form very dense, small stands with limited disturbance, often at the base of a cliff. Soils are relatively deep, well-drained silty to sandy clay loams derived from alluvium, colluvium or glacial till. Elevations range from 715 to 2700 m (2300-8800 feet), with the lower elevations occurring at the northern end of the range in Montana, the higher elevations in Utah and Colorado. The tall (1-2 m) deciduous shrub canopy is dominated by Cornus sericea, generally accompanied by other tall shrubs, including Prunus virginiana, Ribes aureum, Crataegus douglasii, Acer glabrum, Alnus incana, Salix bebbiana, Salix scouleriana, Cercocarpus ledifolius, and Juniperus scopulorum. Short shrubs have sparse to moderate cover and include Rosa woodsii, Symphoricarpos spp., Paxistima myrsinites, Mahonia repens, Arctostaphylos patula, Ribes cereum, and the liana Clematis ligusticifolia. The understory is diverse and ranges from sparse to dense depending on how closed the tall-shrub layer is. Common forbs include Thalictrum occidentale, Solidago canadensis, Aralia nudicaulis, Heracleum maximum, Heliomeris multiflora, Erythronium grandiflorum, Equisetum arvense, Maianthemum stellatum, Sanicula marilandica, Angelica arguta, and Symphyotrichum laeve. Graminoids are generally less important but may include significant cover by Elymus glaucus or Calamagrostis canadensis. The majority of the herbaceous layer may consist of non-native species, including Cirsium arvense, Dactylis glomerata, Agrostis stolonifera, Poa palustris, Phalaris arundinacea, and Phleum pratense.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association appears to be a broadly defined type that may be split in the future as more information becomes available. As such it is low-confidence. All references are surprising similar in their acceptance of variability within this type.
