Name: Festuca campestris - Festuca idahoensis Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This dry-mesic, mid-height grassland is found in the northwestern Great Plains and mountain and foothill slopes on both sides of the Continental Divide. A disjunct occurrence of the association is reported for the Steens Mountains in southeastern Oregon. It occurs on mesic sites from 900-2100 m (3000-7000 feet) elevation on any aspect, becoming restricted to west- and southwest-facing slopes farther north. Slopes vary from flat to gentle toeslopes and lowslopes, generally less than 30%. Soils are loamy and moderately deep on a variety of soil parent materials. This midgrass community is dominated by Festuca campestris and Festuca idahoensis, but Festuca campestris generally has greater canopy cover and can be more abundant on undisturbed sites. A diverse assemblage of herbaceous species has a combined cover ranging from 30-85%. Carex obtusata may be common, especially on more mesic sites. Other graminoids may also be found, including Danthonia intermedia, Koeleria macrantha, Phleum pratense, Achnatherum nelsonii, and Achnatherum occidentale (= Stipa occidentalis). Additional forbs may include Achillea millefolium, Galium boreale, Selaginella densa, Lupinus sericeus, and Geum triflorum. Shrubs are typically present, though in low stature and cover, generally <10%. On rare occasions, shrubs may be present with up to 30% cover. However, in all stands native forbs and grasses dominate this herbaceous association. Shrub species that may be present include Artemisia frigida, Artemisia campestris, Rosa arkansana, Amelanchier alnifolia, and Arctostaphylos uva-ursi. Stands of the association are relatively well adapted to periodic wildfire. While natural fire disturbance regimes of this grassland vegetation are not well known, estimates of fire-return intervals range from 10 to 20 years.  Accession Code: VB.CC.24976.FESTUCACAMPESTR Plot-observations of this Community Concept: 0
