Name: Salix commutata Wet Shrubland Alliance
Reference: NatureServe Biotics 2019
Description: These are short-statured (&lt;1.5 m) willow-dominated communities found at subalpine elevations. Stands within this alliance are classified as seasonally flooded, cold-deciduous shrublands. <i>Salix commutata</i> dominates the shrub canopy with cover of &gt;25%. <i>Salix planifolia</i> and <i>Lonicera caerulea</i> may also be present. <i>Carex scopulorum</i> dominates the herbaceous layer with <i>Calamagrostis canadensis</i>. <i>Galium trifidum</i> has high constancy, and some stands contain a complement of wet-site forbs such as <i>Aconitum columbianum</i> and <i>Caltha leptosepala ssp. howellii</i>. Adjacent communities may be herbaceous bogs dominated by <i>Eleocharis quinqueflora</i>. In some stands, a fringe of <i>Vaccinium uliginosum</i> separates the bog from the willow stands. Stands are confined to narrow riparian zones along upper reaches of streams and to elongated openings in higher elevation forests. Stands are typically found at moderate to high elevations between 2065 and 2220 m in British Columbia, Oregon, Washington, Idaho, western Montana and just into northern California and possibly as far east as Wyoming. Microtopography is usually hummocky to undulating. Slopes range from 2-4%. Soils in Idaho stands are wet to saturated at the surface by flowing groundwater for most or all of the growing season. Soils are poorly to very poorly drained due to accumulation of organic material.
