Name: A.981
Reference: EcoArt 2002
Description: This is a montane riparian shrubland alliance that occurs in the mountains along stream reaches in moderately wide to narrow valleys (20-120 m) with broad, swift-moving streams and active, flat (3-8%) floodplains. Elevations range between 2310 and 3350 m. Large stands occur between meanders and at the edges of beaver ponds. The ground surface is usually undulating, from past flooding or beaver activity. These shrublands occur right at stream's edge, and up to 15 m from the channel, usually >0.5 m above the channel elevation. Soils are predominantly heavy silty clays with occasional to abundant mottling evident. Some stands occur on coarse, well-drained alluvium. The tall-shrub layer is characterized by a tall, nearly closed canopy of ~Salix monticola$ (8-70%), typically with ~Salix geyeriana$ (40-50%) or ~Salix drummondiana$ (10%). Other shrubs present include ~Salix lucida ssp. lasiandra (= Salix lasiandra), Betula nana (= Betula glandulosa), Salix planifolia$, and ~Salix wolfii$. The short-shrub layer is dominated by ~Cornus sericea$ and ~Lonicera involucrata$. The forb layer is dense (up to 50%) and consists of ~Angelica ampla, Geum macrophyllum, Solidago canadensis, Senecio bigelovii$, and ~Galium boreale$. ~Calamagrostis canadensis$ comprises a dense graminoid layer of 40-50% cover. ~Carex utriculata$ and ~Carex aquatilis$ also contribute to the graminoid understory in several associations.
