Name: Pseudoroegneria spicata - Balsamorhiza sagittata - Poa secunda Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This grassland association is described from the foothills and canyon slopes of the eastern Blue Mountains and western Idaho Batholith ecoregional sections and occurs in northeastern Oregon, western Idaho and possibly Washington. Stands occurs on steep, southeast- to southwest-facing slopes on mid- to upper-slope positions of major ridge systems in, typically, highly dissected terrain. Elevations range from 400-1500 m (1300-4900 feet). Soils are often gravelly with abundant cobbles and stones. The plant association is characterized by a relatively open, tall bunchgrass canopy dominated by Pseudoroegneria spicata. Pseudoroegneria spicata is abundant. Poa secunda is consistently present but typically is only common to well-represented. Annual bromes (Bromus briziformis, Bromus japonicus, and Bromus tectorum) and Poa bulbosa are often present and may occur with abundance in degraded stands. Associated herbaceous species include Balsamorhiza sagittata, Lupinus spp., Crepis acuminata, Allium acuminatum, Achillea millefolium, Epilobium brachycarpum (= Epilobium paniculatum), Penstemon deustus, and Collomia grandiflora.  Accession Code: VB.CC.22712.PSEUDOROEGNERIA Plot-observations of this Community Concept: 0
