Name: Purshia tridentata / Pseudoroegneria spicata Shrub Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This plant association is described from sites in the Eastern Cascades, Blue Mountains, and Bitterroot Valley ecoregional sections. Stands are also reported from the southwestern portion of the Idaho Batholith section. The association occurs on steep, south-facing, mid to upper slopes at 1900-5500 feet elevation (typically at higher elevation in the eastern portion of the range). Soils are typically dry, shallow, and rocky. A high exposure of rock and surface soil is common. Relatively open stands of Purshia tridentata occur with Pseudoroegneria spicata and Balsamorhiza sagittata. Poa secunda and Lomatium dissectum are often also present.  Accession Code: VB.CC.22826.PURSHIATRIDENTA Plot-observations of this Community Concept: 0
