Name: A.1001 Reference: EcoArt 2002 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 stream flows, 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.772.A1001 Plot-observations of this Community Concept: 0
