Name: A.1007
Reference: EcoArt 2002
Description: Communities within this cold-deciduous, seasonally flooded shrubland alliance occur on alluvial terraces adjacent to mountain rivers and streams. They occupy broad floodplains (0-6% slope), stream and river edges, ditches, seeps, and moist alluvial terraces. Stands are associated with beaver ponds or lakes. Elevations range from 1100-3600 m. The soils are typically peaty Histosols. Soils texture ranges from sandy clay loam to silt. These soils are saturated early in spring and often remain moist throughout the growing season. The tall-shrub canopy is continuous and dominated by ~Salix lutea$ with varying amounts of ~Salix exigua, Salix bebbiana$, and ~Salix boothii$. The short-shrub layer cover is typically 25% or greater and consists of ~Ribes aureum, Ribes inerme$, and ~Rosa woodsii$. The graminoid layer ranges from sparse to dense canopy cover. Major herbaceous species include ~Calamagrostis canadensis, Carex utriculata, Calamagrostis stricta$, and ~Carex microptera$. Adjacent upland communities include ~Pinus contorta$ and ~Populus tremuloides$.
