Name: Pseudoroegneria spicata - Poa secunda Lithosolic Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This association is known from sites in the lower Snake River basin and northern Wallowa Mountains. Stands also appear to occur in the upper Hells Canyon region within Idaho. The association is transitional to ridgetop habitats that do not support Pseudoroegneria spicata (Poa secunda - Danthonia unispicata sites) and those that support Festuca idahoensis (e.g., Festuca idahoensis - Koeleria macrantha sites). The association occurs on gentle to moderately steep, south- to southwest-facing convex ridgetops at 4000-5200 feet elevation. Shallow soils are derived from basalt bedrock. Pseudoroegneria spicata dominates these scabland bunchgrass stands. Poa secunda is codominant. Principal indicator forbs include Lomatium cous, Erigeron chrysopsidis, Balsamorhiza incana, Sedum lanceolatum, and Sedum stenopetalum.  Accession Code: VB.CC.23704.PSEUDOROEGNERIA Plot-observations of this Community Concept: 0
