Name: Alnus incana / Equisetum arvense Shrubland
Reference: Western Ecology Working Group of...
Description: These seasonally flooded, tall shrublands have been reported from montane sites in Colorado, Utah, Oregon, Washington, and may occur in California and Idaho. They have been described from frequently flooded streambanks, swales, floodplains, and shores of lakes and ponds. Soils range from shallow loamy sand, loam or silt over alluvial gravel or cobbles, to organic loam, peat and muck. Vegetation is dominated by a moderate to dense canopy (>40% cover) of the deciduous, broad-leaved tall shrub <i>Alnus incana ssp. tenuifolia</i>. Other shrubs may include scattered <i>Salix, Betula, Cornus</i>, or <i>Ribes</i> spp. <i>Equisetum arvense</i> often forms a thick carpet beneath young to mature alder shrubs. Mesic forbs or other graminoids are typically sparse but may include <i>Calamagrostis canadensis, Glyceria striata (= Glyceria elata)</i>, Asteraceae spp., <i>Galium boreale</i>, or <i>Geum macrophyllum</i>. This shrubland can be distinguished from other <i>Alnus incana ssp. tenuifolia</i>-dominated shrublands by the presence of at least 25% cover of <i>Equisetum arvense</i>.
