Description: Communities within the ~~Salix drummondiana$ Seasonally Flooded Shrubland Alliance (A.1004)$$ occur on alluvial terraces adjacent to mountain rivers and streams. Occurrences occupy gentle undulating surfaces with slopes ranging from 5-30%. They range in elevation from 2135-3300 m. These communities are often associated with beaver activity. They are typically located adjacent to beaver ponds, lakes, seeps and springs, and on alluvial terraces adjacent to mountain rivers and streams. Soils are usually peaty with organic matter accumulation. Soil textures range from silt to clay loam. Water tables are usually at or near the surface. Gleyed soil is common at any depth. Soil texture is fine-loamy, loamy-skeletal, and sandy. The soils classify as Cryaquolls and Cryaquepts. Vegetation types within this alliance are classified as seasonally flooded, cold-deciduous shrublands. ~Salix drummondiana$ dominates the tall-shrub layer with open, corridor-like canopies with a dense graminoid layer in the understory. ~Salix monticola, Salix planifolia$, and ~Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda)$ are often present in the shrub layer. The graminoid layer is typically dominated by ~Carex utriculata$ with cover of 50-75%. Forb cover is relatively low. Species can include ~Geum macrophyllum$ and ~Epilobium ciliatum$ with 1-10% cover. ~Pinus contorta$ and ~Populus tremuloides$ forests occur on adjacent hillslopes.
