Name: Alnus rubra / Rubus spectabilis / Carex obnupta - Lysichiton americanus Riparian Forest
Reference: NatureServe Biotics 2019
Description: 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 <i>Alnus rubra</i> between 20-50 years old and have relatively few species in the shrub and herb layers. <i>Thuja plicata, Picea sitchensis</i>, and <i>Tsuga heterophylla</i> are sparsely represented in both mature and reproducing layers, where they are peripheral or limited to elevated microsites. The scanty shrub layer may include <i>Rubus ursinus, Salix hookeriana, Spiraea douglasii, Lonicera involucrata</i>, or <i>Rubus spectabilis</i> in wet areas and may have <i>Gaultheria shallon</i> and <i>Acer circinatum</i> on stumps and logs. The herb layer is dominated by <i>Carex obnupta</i> and <i>Lysichiton americanus</i>. <i>Athyrium filix-femina</i> has a constancy of 23%, but cover never exceeds 10%. <i>Polystichum munitum</i> may be abundant on logs and stumps. Expanses of treacherously deep muck frequently occur between clumps of <i>Carex</i> and <i>Lysichiton</i>. <i>Sphagnum</i> does not occur in this association but <i>Eurhynchium praelongum</i> is common.
