CEGL002949 Quercus gambelii / Poa fendleriana Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Gambel Oak / Muttongrass Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This montane shrubland association has been described from the Colorado Plateau and the western slope of the southern Rocky Mountains. Elevation ranges from 1770-2337 m (5800-7660 feet). Sites are on nearly level mesas to steep hillslopes (to 59%). Soils are rapidly drained loamy sand and sandy loam derived from sandstones. There is typically high cover of litter and moderate cover of large rocks and bare ground. The vegetation is characterized by an open to moderately dense (10-65% cover) tall-shrub layer (2-5 m tall) that is dominated by Quercus gambelii. Other shrubs may be present with low cover and do not form a separate short-shrub layer (generally <10% total). Species include Amelanchier utahensis, Artemisia tridentata ssp. wyomingensis, Purshia tridentata, Mahonia repens, and Symphoricarpos spp. The herbaceous layer may be diverse and provides low to high cover depending on overstory canopy density. The bunchgrass Poa fendleriana is usually dominant (to 30% cover) and occurs consistently. Additional graminoids provide sparse to low cover, such as Achnatherum hymenoides, Bouteloua gracilis, Carex geyeri, and Hesperostipa comata. Forbs typically have low cover but may be diverse. Common forbs include Arenaria spp., Artemisia ludoviciana, Eriogonum spp., Petradoria pumila, and Phlox austromontana.
