Name: Ostrya knowltonii Woodland
Reference: Western Ecology Working Group of...
Description: This woodland association is known from a single occurrence in Glen Canyon National Recreation Area from an intermittently flooded alcove on a wash bottom. The site is a moderate slope oriented to the west at 1603 m elevation. Litter and exposed soil cover most of the unvegetated surface, with lesser cover by sand, bedrock and dead wood. The soil is a rapidly drained loamy sand derived from alluvium. This riparian woodland is rare within the recreation area. Total vegetation cover is 92%. The stand is characterized by a dense canopy of the tall shrub <i>Ostrya knowltonii</i> with up to 40% cover. Scattered <i>Populus fremontii, Pinus edulis</i>, and <i>Juniperus osteosperma</i> emerge from the shrub canopy but do not constitute a tree layer. Associated shrubs include <i>Amelanchier utahensis, Fraxinus anomala, Rhus trilobata, Symphoricarpos longiflorus</i>, and <i>Yucca angustissima</i>. The riparian vine <i>Clematis ligusticifolia</i> provides sparse cover. The herbaceous layer is diverse and provides significant cover. Common grasses include <i>Sporobolus airoides</i> and <i>Poa fendleriana</i>. The forbs <i>Solidago canadensis</i> and <i>Heterotheca villosa</i> provide low to moderate cover, and <i>Aquilegia micrantha, Cirsium calcareum, Thelypodium integrifolium</i>, and <i>Castilleja linariifolia</i> are generally present.
