Name: Salix boothii Seasonally Flooded Shrubland Alliance Reference: Western Ecology Working Group of... Description: This widespread alliance occurs throughout much of the western U.S. at elevations from 1320-2800 m. Sites include valley bottoms on swales, banks, and occasionally terraces of stream channels which receive surface water for extended periods of time, especially during the early part of the growing season. Stands adjacent to the stream channel receive moisture from overland and lateral streamflows and are often associated with beaver ponds. Stands occur on terraces that have a continually high water table. Vegetation in the alliance is also located adjacent to seeps on gently sloping toeslopes and occasionally in bogs or fens. Soils generally have a deep organic layer with some minerals, fine sands, loams, and clays, and gravel or cobbles below. Communities within this shrubland alliance are characterized by a moderately dense to dense Salix boothii-dominated tall-shrub layer. Other shrubs may codominate, including Salix geyeriana, Salix planifolia, or Salix drummondiana. Salix wolfii may occasionally form a relatively sparse low-shrub layer. Other shrubs may include Lonicera involucrata, Betula nana (= Betula glandulosa), and Ribes spp. The moderately dense to dense herbaceous layer is dominated by graminoids and includes Carex aquatilis, Carex utriculata, Carex nebrascensis, Deschampsia caespitosa, Juncus balticus, and Trisetum wolfii. Forb cover is sparse to moderately dense. Common forbs are Symphyotrichum foliaceum (= Aster foliaceus), Hedysarum sulphurescens, Geum macrophyllum, Mertensia ciliata, Trollius laxus, and Urtica dioica. Diagnostic of this wetland alliance is a Salix boothii-dominated or codominated tall shrubland that is flooded for extended periods during the growing season.  Accession Code: VB.CC.20021.SALIXBOOTHIISEA Plot-observations of this Community Concept: 0
