Name: Quercus gambelii / Festuca thurberi Shrubland Reference: NatureServe Biotics 2019 Description: This tall-shrub association is only described from Curecanti National Recreation Area in west-central Colorado. Stands occur on moderately steep (29-48%) slopes and ridges, between 2667 and 2718 m elevation, and are oriented to all aspects. The unvegetated surface has high cover of litter. Parent materials are Tertiary volcanic rocks and metamorphic/granitic rocks. Soils are rapidly drained silty clay loams. The vegetation is characterized by an open to nearly closed shrub canopy 1-5 m tall dominated by <i>Quercus gambelii</i>, which contributes 6 to 100% cover, and the tall bunchgrass <i>Festuca thurberi</i> which provides 25 to 100% cover. The shrub layer is moderately diverse in terms of species composition and provides moderate to dense cover. Short and dwarf-shrubs include <i>Amelanchier alnifolia, Amelanchier utahensis, Artemisia tridentata ssp. vaseyana, Chrysothamnus viscidiflorus, Rosa woodsii</i>, and <i>Symphoricarpos rotundifolius</i>. Occasionally <i>Quercus gambelii</i> will attain tree height (5-10 m tall) and structure. The herbaceous layer is diverse in terms of species composition and provides moderate to dense cover. Additional graminoids that provide sparse to low cover include <i>Carex geyeri, Elymus elymoides, Bromus porteri, Poa fendleriana</i>, and <i>Poa pratensis</i>. Forbs provide sparse cover and include <i>Achillea millefolium var. occidentalis, Arabis drummondii, Balsamorhiza sagittata, Eriogonum umbellatum, Galium boreale</i>, and <i>Ligusticum porteri</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:31707-{FC7AB1EC-A399-40B8-96EF-EECF55DFF9FB} Plot-observations of this Community Concept: 0
