Name: Rhus trilobata Intermittently Flooded Shrubland Alliance Reference: Western Ecology Working Group of... Description: This riparian shrubland alliance forms linear bands on rocky, well-drained benches and toeslopes in the foothills and mountains. Elevations range from 600 m in New Mexico to 2000 m in Colorado. Types occur at the bottom of cliffs and on toeslopes in very narrow, steep (>50%), rocky river reaches having little floodplain development due to bedrock confinement. They often occur as a narrow band on rocky, well-drained benches located between the high-water line and the upland slopes in moderately wide valleys and along narrow reaches of larger rivers. Soil textures are shallow sandy loam or loamy sands over coarse alluvium or bedrock. A dense shrub layer dominated by up to 60% cover of Rhus trilobata characterizes types. Other shrubs can include Prunus serotina, Ribes aureum, Salix ligulifolia (= Salix eriocephala var. ligulifolia), Salix exigua, Berberis fendleri, Rosa woodsii, and Juniperus monosperma. The herbaceous layer is typically sparse due to shading, but can be composed of any of the following: Muhlenbergia montana, Pseudoroegneria spicata, Calamovilfa longifolia, Carex filifolia, Festuca idahoensis, or Schizachyrium scoparium. Salix exigua shrublands typically occur as a narrow band within the channel below the height of the Rhus trilobata types.  Accession Code: VB.CC.20393.RHUSTRILOBATAIN Plot-observations of this Community Concept: 0
