Name: Salix eastwoodiae Seasonally Flooded Shrubland Alliance Reference: Western Ecology Working Group of... Description: Communities within the Salix eastwoodiae Seasonally Flooded Shrubland Alliance (A.1005) are scattered throughout the high-elevation, late snowmelt areas. They are found within glacial valley bottoms (e.g., seeps, toeslopes, benches, and stream benches), wet mountain meadows, and streambanks with gentle slopes (3%). Elevations range from 2300-3200 m. Sites that support these communities contain surface waters that collect in rivulets or are fed by seeps with water flowing at or near the surface. Soils are characterized by organic surface horizons. Textures of the underlying mineral horizons range from silty clay loam to loam sand. Vegetation types within this alliance are characterized as cold-deciduous seasonally flooded shrublands. They are dominated by Salix eastwoodiae. Salix planifolia, Salix boothii, and Betula nana (= Betula glandulosa) also occur in the shrub layer. Total shrub cover varies from 30 to over 75%. Carex scopulorum, Carex aquatilis, and Carex utriculata are usually dominant in the understory with at least 40% cover. Carex cusickii (= Carex obovoidea) and Carex luzulina are frequent and abundant. Calamagrostis canadensis is a dominant graminoid in their Idaho stands. Forb cover is low with Mertensia ciliata, Saxifraga odontoloma, and Thalictrum occidentale. Adjacent upland communities are dominated by Pinus monticola, Pinus contorta, and Abies concolor.  Accession Code: VB.CC.18043.SALIXEASTWOODIA Plot-observations of this Community Concept: 0
