Name: Festuca idahoensis - Pseudoroegneria spicata Palouse Grassland Alliance Reference: NatureServe Biotics 2019 Description: This alliance is characterized by medium-tall bunchgrasses <i>Pseudoroegneria spicata, Festuca idahoensis</i>, and/or <i>Hesperostipa comata</i> dominating the midgrass layer. Some stands have a short bunchgrass layer of <i>Poa secunda</i>. Broad-leaved herbs typically contribute little to the composition of individual sites but may include <i>Achillea millefolium var. occidentalis, Eriogonum heracleoides</i>, and <i>Lomatium</i> sp. Scattered <i>Ericameria</i> spp. shrubs can be present to abundant especially on disturbed sites. Annual grasses and forbs are common and can be diverse. In disturbed sites <i>Bromus tectorum</i> and <i>Plantago patagonica</i> are common. A diverse ground moss and lichen layer can cover much of the space between vascular plants, although it can be displaced with ground disturbance. This alliance occurs in remnants of the Palouse Prairie of southeastern Washington, Oregon and Idaho. Stands occur on ridgetops or on flat to concave surfaces on the middle or upper third of the slope between 1580-1935 m elevation. Slopes range from flat to 110%, and stands can be found on all aspects. This is an open to closed vegetation type with most of its total cover found in only the medium-tall bunchgrass lifeform.  Accession Code: urn:lsid:vegbank.org:commConcept:39199-{71DBA05D-BC25-401C-86F1-9C8750E54B99} Plot-observations of this Community Concept: 0
