Description: Communities found within the ~~Salix commutata$ Seasonally Flooded Shrubland Alliance (A.1003)$$ are found in the subalpine zone. 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. Microtopography is usually hummocky to undulating. Slopes range from 2-4%. Soils in the 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. Vegetation stands within this alliance are classified as seasonally flooded cold-deciduous shrublands. ~Salix commutata$ dominates the shrub canopy with cover of >25%. ~Salix planifolia$ and ~Lonicera caerulea$ may also be present. ~Carex scopulorum$ dominates the herbaceous layer with ~Calamagrostis canadensis$. ~Galium trifidum$ has high constancy, and some stands contain a complement of wet site forbs such as ~Aconitum columbianum$ and ~Caltha leptosepala ssp. howellii (= Caltha biflora)$. Adjacent communities may be herbaceous bogs dominated by ~Eleocharis quinqueflora (= Eleocharis pauciflora)$. In some stands, a fringe of ~Vaccinium uliginosum (= Vaccinium occidentale)$ separates the bog from the willow stands.
