Name: Salix geyeriana Seasonally Flooded Shrubland Alliance Reference: Western Ecology Working Group of... Description: Communities within this temporarily flooded, cold-deciduous 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. Surface textures are silt to silty clay loam with mottling near the surface. Soils have a high water-holding capacity. Organic matter may accumulate on the surface. The communities are characterized by a tall-shrub layer dominated by Salix geyeriana. 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.  Accession Code: VB.CC.18045.SALIXGEYERIANAS Plot-observations of this Community Concept: 0
