Name: Salix lasiolepis Wet Shrubland Alliance
Reference: NatureServe Biotics 2019
Description: The tall-shrub layer of this alliance is dominated by <i>Salix lasiolepis</i> which forms a dense overstory ranging from 60-100% cover. Other shrubs that may be equally important include <i>Baccharis pilularis, Baccharis salicifolia, Cephalanthus occidentalis, Cornus sericea, Morella californica</i>, and <i>Toxicodendron diversilobum</i>. Emergent trees may include <i>Acer macrophyllum, Platanus racemosa, Populus balsamifera, Populus fremontii, Salix</i> spp., and <i>Sambucus nigra ssp. canadensis</i>. <i>Ribes aureum, Rosa californica</i>, or <i>Rosa woodsii</i> typically form a low-shrub layer near the base of the willows. The undergrowth is typically depauperate, with <i>Clematis ligusticifolia</i> and <i>Maianthemum stellatum</i> present in minor amounts. Bare ground and/or leaf litter from the willow overstory are characteristic. This alliance occurs in California, Nevada, southwestern Utah, Oregon, and Idaho. Communities within this cold-deciduous, temporarily (or seasonally) flooded shrubland alliance occupy stream benches and occasionally seeps. They can form stringer communities along drainages with slopes ranging from 1-15%. Elevations range between 259 and 2490 m. Soils are xeric and developed on alluvium. Water tables were rarely reached by researchers within the depth of soil pits, and mottles were not evident because of the coarse soil texture.
