Name: Festuca idahoensis - Eriogonum heracleoides Grassland Reference: NatureServe Biotics 2019 Description: These grasslands are described from parks in the forests of the Okanogan Highlands of northeastern Washington and southern British Columbia, and from Oregon. Stands may also occur in northern Idaho. This association occurs as grassland 'parks' from 670 m to over 2000 m elevation in the <i>Pinus ponderosa</i> and <i>Pseudotsuga menziesii</i> zones. Sites are typically on dry slopes with southern exposures; apparently too dry during the late summer to support trees. Soils are loams to gravelly fine sandy loams, developed on bedrock controlled glacial tills. The vegetation is a medium-tall grassland association, dominated by the perennial bunchgrasses <i>Festuca idahoensis</i> or <i>Festuca campestris</i>, with <i>Pseudoroegneria spicata, Poa secunda</i>, and <i>Koeleria macrantha</i>. The diagnostic species <i>Eriogonum heracleoides</i>, a low (1-4 dm tall), perennial, suffrutescent forb, does not contribute to the physiognomic structure of this type, and is often sparsely present. There is a rich perennial forb component, including such species as <i>Achillea millefolium, Lomatium triternatum, Erigeron corymbosus</i>, and <i>Balsamorhiza</i> spp. Stands are distinguished from other <i>Festuca idahoensis</i> stands by the presence of <i>Eriogonum heracleoides</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:30525-{7A61EA4B-4093-4223-94AA-FFE4A32084C3} Plot-observations of this Community Concept: 0
