Description: Communities within the ~~Salix planifolia$ Seasonally Flooded Shrubland Alliance (A.1008)$$ are common and abundant in the upper montane and subalpine zones (above 1525 m) throughout the western United States. They occur in wide, wet valleys on snowmelt-fed swales. They also occur in narrow valleys with sinuous streams and wet floodplains associated with beaver ponds. Snowmelt is the primary source of moisture during the growing season. Soils have an organic peat top layer over mineral silty clays, heavy silty clay loams, silty loams, sandy loams, or loamy sands. Mottling is often evident. The water table at several stands is usually near the surface throughout the growing season and may be perched by a clay horizon. Still other stands occur on deep, dark clay loams with high organic content or a fibric or hemic layer on top. Soil pH levels are acidic, ranging from 4.8-7.8. ~Salix planifolia$ dominates the shrub layer with at least 70% cover. Other willows can include ~Salix monticola, Salix wolfii, Salix boothii, Salix geyeriana$, and ~Salix drummondiana$. The undergrowth is dominated by graminoids and can include ~Carex aquatilis, Carex utriculata, Calamagrostis canadensis$, and ~Deschampsia caespitosa$. Forb cover is typically less than 20% of the total undergrowth cover and may include ~Caltha leptosepala, Cardamine cordifolia$, and ~Pedicularis groenlandica$. Adjacent riparian and wetland vegetation includes ~Carex aquatilis, Carex utriculata$, or ~Calamagrostis canadensis$ wet meadows. ~Salix brachycarpa$ shrublands occur on higher ground. At higher elevations, ~Abies lasiocarpa - Picea engelmannii$ or ~Pinus contorta$ forests occur on adjacent hillsides.
