Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Red Alder / Salmonberry / Slough Sedge - Yellow Skunk-cabbage Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: Habitat for this association is forested wetland (swamp). Some sites are silted-in beaver ponds, and others are in peatlands where the association occurs in nutrient-rich laggs adjacent to uplands. Stands along streams may be flooded for brief periods after winter storms. Stands are dominated by Alnus rubra between 20-50 years old and have relatively few species in the shrub and herb layers. Thuja plicata, Picea sitchensis, and Tsuga heterophylla are sparsely represented in both mature and reproducing layers, where they are peripheral or limited to elevated microsites. The scanty shrub layer may include Rubus ursinus, Salix hookeriana, Spiraea douglasii, Lonicera involucrata, or Rubus spectabilis in wet areas and may have Gaultheria shallon and Acer circinatum on stumps and logs. The herb layer is dominated by Carex obnupta and Lysichiton americanus. Athyrium filix-femina has a constancy of 23%, but cover never exceeds 10%. Polystichum munitum may be abundant on logs and stumps. Expanses of treacherously deep muck frequently occur between clumps of Carex and Lysichiton. Sphagnum does not occur in this association but Eurhynchium praelongum is common.
