Name: Juniperus osteosperma / Quercus havardii - Artemisia filifolia - Ephedra cutleri Sandsheet Scrub Reference: NatureServe Biotics 2019 Description: This open scrub is known from Glen Canyon National Recreation Area and likely occurs more widely on sandy sites in the Colorado Plateau. It is characterized by a sparse to open tree canopy composed of <i>Juniperus osteosperma</i> with 3-15% cover. The shrub layer is dominated by <i>Quercus havardii</i> and codominated by <i>Ephedra cutleri</i> and <i>Artemisia filifolia</i>. Other commonly associated shrubs include <i>Eriogonum leptocladon</i> and <i>Vanclevea stylosa</i>. The herbaceous layer is typically dominated by graminoids with <i>Achnatherum hymenoides</i> always present and usually dominant. Many other native grasses may be present with low to moderate cover such as <i>Bouteloua gracilis, Sporobolus contractus, Sporobolus cryptandrus, Sporobolus flexuosus, Sporobolus giganteus, Muhlenbergia pungens, Pleuraphis jamesii</i>, and <i>Vulpia octoflora</i>. Native forbs have sparse to low cover with moderately low diversity. Exotic annuals <i>Bromus tectorum</i> and <i>Salsola tragus</i> may be present with sparse to low cover. This sandy site scrub occurs on benches, sand dunes/dunefields, sandsheets and mesas between 1491 and 1546 m elevation. Sites are gently to moderately sloping with mostly westerly aspects. Bare soil and sand cover most of the unvegetated surface, with lesser cover by dark cyanobacteria, litter, gravel, and bedrock. Soils are loamy sands derived from eolian deposits or from sandstones.  Accession Code: urn:lsid:vegbank.org:commConcept:37400-{78FACF96-FFD7-4607-894D-86CAE5919E24} Plot-observations of this Community Concept: 0
