Name: Salix drummondiana Temporarily Flooded Shrubland Alliance Reference: Western Ecology Working Group of... Description: Communities within this alliance occur on alluvial terraces adjacent to mountain rivers and streams. They range in elevation from 2135-3300 m, on slopes that range from 5-30%. These shrublands occur as small, isolated patches in forest and shrubland openings along channels in narrow valley bottoms along steep, narrow stream margins. They are often associated with beaver activity and can occasionally occur along low-gradient streams. Soils are usually poorly developed and contain high percentages of gravel and cobbles. Water table depths range from surface level to greater than 1 m. Open, corridor-like canopies characterize this major riparian alliance with a dense graminoid layer in the understory. They are cold-deciduous, temporarily flooded shrublands that are dominated by Salix drummondiana. Alnus incana and Salix geyeriana are often present in the shrub layer. The graminoid layer is dominated by Calamagrostis canadensis with cover of 50-75%. Carex aquatilis and Carex utriculata can be present is lesser amounts (0-30% cover). Forb cover is relatively low. It is characterized by Geum macrophyllum, Equisetum arvense, and Canadanthus modestus (= Aster modestus). Populus tremuloides woodlands and Abies lasiocarpa - Picea engelmannii forests occur on adjacent hillsides.  Accession Code: VB.CC.23037.SALIXDRUMMONDIA Plot-observations of this Community Concept: 0
