Name: Quercus gambelii / Symphoricarpos oreophilus Shrubland Reference: Western Ecology Working Group of... Description: This plant association is found in the foothills, plateaus and mountains from western Texas to southern and western Colorado and northern Utah, and likely occurs in northern Arizona. It is a mesic upland and a non-obligate riparian community that appears to be transitional between riparian areas and drier upland communities such as Artemisia spp. It occurs on cool, moist sites, such as along drainages in canyons and steep draws in more xeric areas, and as a mesic upland shrubland forming extensive stands on cooler northern slopes. Substrates are typically deep, well-drained sandy loam to clay loam derived from alluvium or colluvium. The vegetation is characterized by an open to closed, typically tall-shrub layer (2-5 m tall) that is dominated by Quercus gambelii. The understory is composed of a short-shrub layer that is dominated by Symphoricarpos oreophilus or a closely related local Symphoricarpos species such as Symphoricarpos rotundifolius or Symphoricarpos palmeri. Other mesic shrubs may be present including Amelanchier spp., Prunus virginiana, Robinia neomexicana, and Brickellia sp. In some stands, the Quercus gambelii develop into small trees that form a tree canopy. These "woodlands" are included in this association because their floristic composition is identical to the tall shrublands. In other stands the oak is mostly under 2 m tall, forming a short-shrub layer. The herbaceous layer is sparse to moderately dense, depending on density of woody canopy, and is often dominated by graminoids such as species of Achnatherum, Bromus, Elymus, Poa, and Koeleria. Common forbs include Vicia americana, Thalictrum fendleri, and Achillea millefolium. Occasionally, tree species are present in the overstory.  Accession Code: VB.CC.25230.QUERCUSGAMBELII Plot-observations of this Community Concept: 0
