Name: Quercus garryana / Festuca idahoensis Woodland Reference: Western Ecology Working Group of... Description: This association is based on field observations and six releves. The association mostly occurs at lower conifer treeline within and below the <i>Pinus ponderosa</i> zone. It typically occurs as small balds in <i>Pseudotsuga menziesii</i>, and rarely <i>Abies grandis</i>, forests on xeric sites, and on open, northerly slopes within communities in the <i>Festuca idahoensis - Hieracium cynoglossoides</i> steppe zone. These communities are shrub-free with only scattered <i>Ceanothus integerrimus</i> or <i>Symphoricarpos albus</i> in moist variants or <i>Purshia tridentata</i> in dry/hot variants. <i>Quercus garryana</i> trees are scattered with cover of 10-65%; conifers may be found singly or as invaders. <i>Festuca idahoensis</i> is the dominant grass with 10-50% cover between the oaks while <i>Elymus glaucus</i> predominates under the oaks. Other graminoids include <i>Pseudoroegneria spicata, Carex geyeri, Koeleria macrantha, Achnatherum occidentale (= Stipa occidentalis)</i>, and <i>Poa</i> spp. Forb diversity is relatively low. Exotic annual grasses (<i>Bromus rigidus, Bromus tectorum, Cynosurus echinatus, Ventenata dubia</i>) are a common feature particularly in grazed examples.  Accession Code: VB.CC.32653.CEGL000551 Plot-observations of this Community Concept: 0
