Name: Aristida purpurea var. longiseta - Sporobolus cryptandrus Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This grassland community is found in Oregon and Washington, and may occur in Idaho. Stands are found at elevations of 370-460 m (1200-1500 feet) on terraces and alluvial bars associated with the Snake River. Slopes are 5-22% with variable aspects. Soils are silt or sandy loams underlain by gravel and rock. This vegetation is codominated by <i>Sporobolus cryptandrus, Aristida purpurea var. longiseta</i>, and introduced annual <i>Bromus</i> spp. with 15%, 14%, and 36% cover, respectively. Non-native forbs, <i>Hypericum perforatum</i> and <i>Erodium cicutarium</i> are important forbs with 5% and 1% cover, respectively. In the absence of significant livestock use, this community would have increased cover of <i>Sporobolus cryptandrus</i> and <i>Aristida purpurea var. longiseta</i>, and no introduced species.  Accession Code: VB.CC.34386.CEGL001515 Plot-observations of this Community Concept: 0
