Name: Eriogonum sphaerocephalum / Poa secunda Dwarf-shrub Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This plant association is described for the Columbia Plateau of southeastern Washington and northeastern Oregon. Stands are also known from the upper Hells Canyon in Idaho. The association occurs on basalt Lithosol sites ranging in elevation of 1600-3100 feet on the Columbia Plateau and 3500-4500 in the upper Hells Canyon region. The association is characterized by an open dwarf-shrub canopy dominated by Eriogonum sphaerocephalum. The relatively sparse understory is dominated by Poa secunda, and Eriogonum thymoides may also be present. Pseudoroegneria spicata and Elymus elymoides are commonly present with low abundance. Forb composition is variable. Trifolium macrocephalum, Balsamorhiza hookeri, Lomatium bicolor var. leptocarpum (= Lomatium leptocarpum), and Allium acuminatum are often present.  Accession Code: VB.CC.24958.ERIOGONUMSPHAER Plot-observations of this Community Concept: 0
