Name: Festuca idahoensis - Pseudoroegneria spicata Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This mid-grassland is abundant in western Montana, southern Idaho and eastern Washington near the Snake River. It also occurs in northeastern California. It occurs at 900 to 2300 m (2950-7500 feet) elevation, on mostly gently rolling to flat topography, but can be found on relatively steep slopes as well. It tends to occur more on northerly exposures at the lower elevations and on southerly exposures at the higher elevations. The vegetation is characterized by the presence and dominance of Festuca idahoensis and Pseudoroegneria spicata (= Agropyron spicata) and usually Poa secunda (= Poa sandbergii). Cover ranges from 5-60% for each species, and their combined cover is usually much greater than any forb component present. Commonly associated graminoid species include Carex filifolia, Danthonia intermedia, Leymus cinereus (= Elymus cinereus), Poa cusickii, Koeleria macrantha, Hesperostipa comata and Achnatherum occidentale (= Stipa occidentalis). Forb species composition varies, depending on aspect and geographic distribution. Total forb cover ranges from 3 to 33%. Common forb species include Achillea millefolium, Antennaria rosea, Lupinus sericeus, Arenaria congesta, Lithophragma glabrum (= Lithophragma bulbiferum), and Phlox hoodii. Scattered low-stature shrubs may be present and include Chrysothamnus viscidiflorus, Ericameria nauseosa, and Artemisia tridentata.  Accession Code: VB.CC.26450.FESTUCAIDAHOENS Plot-observations of this Community Concept: 0
