Name: Salix geyeriana / Calamagrostis canadensis Shrubland Reference: Western Ecology Working Group of... Description: This riparian shrubland often forms large expanses of willows on broad montane valley floors. Stands have a 2- to 3-m tall, cold-deciduous shrub canopy that is dominated by <i>Salix geyeriana</i>. The ground is usually hummocky with a dense herbaceous layer that is dominated by the perennial graminoid <i>Calamagrostis canadensis</i>. These shrublands are often associated with beaver-created wetlands. This shrubland generally occurs on broad, flat mountain valleys where the valley gradient is not more than 5% between 1585 and 3050 m (5200-10,000 feet) in elevation. It is known from Idaho, Montana, Utah, Nevada, Wyoming and Colorado. This is a tall, cold-deciduous willow shrubland with an open canopy of <i>Salix geyeriana</i>. The stands are generally open with only 40% cover but can occur with a near-continuous canopy. A shorter shrub layer is often present, these generally tucked underneath the taller willows, even in more open stands, although short shrubs away from the taller canopy are not unexpected. Common coexisting tall shrubs include <i>Salix boothii</i> and <i>Salix drummondiana</i>. Common shorter shrub species include <i>Salix planifolia, Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda), Lonicera involucrata, Ribes lacustre</i>, and <i>Betula glandulosa</i>. The undergrowth is a very thick carpet of graminoids dominated by <i>Calamagrostis canadensis</i>. <i>Carex aquatilis</i> and <i>Carex utriculata</i> are often present but never in as great abundance as <i>Calamagrostis canadensis</i>. <i>Bromus ciliatus, Poa pratensis, Deschampsia caespitosa</i>, and <i>Phleum alpinum</i> are also commonly encountered. Forbs contribute very little to the overall biomass but are always present in small amounts. No species are consistently present, but often seen species include <i>Geum macrophyllum, Thalictrum fendleri, Heracleum maximum</i>, and <i>Fragaria virginiana</i>.  Accession Code: VB.CC.32531.CEGL001205 Plot-observations of this Community Concept: 0
