Reference: EcoArt 2002
Description: Communities within this riparian shrubland alliance occur from the foothills to high elevations in the mountains of the western United States. Elevation ranges from 1320-2900 m. Landforms include broad benches and alluvial terraces of streams, springs, and seeps. Stands often develop on abandoned and sediment-filled beaver ponds. Soils are composed of deep, fine-textured alluvium over subsurface soils of various textures and origin. Soils have a high water-holding capacity. A tall-shrub layer dominated by ~Salix geyeriana$ characterizes these communities. Occasional codominants include ~Salix monticola, Salix boothii, Salix lemmonii$, or ~Salix eriocephala$. Some stands have shorter willows in the understory, including ~Salix wolfii$ and ~Salix planifolia$. Other shrub species include ~Lonicera utahensis, Dasiphora fruticosa ssp. floribunda (= Pentaphylloides fruticosa)$, and ~Ribes$ spp. ~Calamagrostis canadensis, Calamagrostis stricta, Poa palustris, Deschampsia caespitosa, Carex aquatilis$, and ~Carex utriculata$ are the dominant graminoid species with 10-60% cover. The forb layer is minor with 10-20% cover and includes ~Geum macrophyllum, Pyrola asarifolia, Galium trifidum$, and ~Epilobium ciliatum$. ~Populus tremuloides, Pinus contorta$, and ~Pinus ponderosa$ forests occur on surrounding hillslopes.
