Name: Psorothamnus fremontii Wash Shrubland Reference: NatureServe Biotics 2019 Description: This Fremont's smokebush shrubland association is currently described from the Colorado Plateau and northeastern Mojave Desert. Vegetation is moderately dense (39-45% total cover) and dominated by <i>Psorothamnus fremontii</i>, with 10-18% cover. <i>Larrea tridentata</i> is commonly found in a very sparse tall-shrub layer in lower elevation stands. The short-shrub layer also occasionally includes <i>Ambrosia dumosa, Atriplex confertifolia, Ericameria nauseosa, Ephedra torreyana, Gutierrezia sarothrae, Hymenoclea salsola, Krameria grayi</i>, and <i>Opuntia basilaris</i>. Graminoid cover is quite sparse and generally weedy. Natives <i>Vulpia octoflora</i> and <i>Dasyochloa pulchella</i> may occur in some stands with exotics <i>Bromus tectorum</i> and <i>Schismus barbatus</i> common in disturbed stands. <i>Eriogonum inflatum</i> regularly occurs in the forb understory, while <i>Cryptantha</i> sp., <i>Antheropeas lanosum, Lepidium montanum, Oenothera</i> spp., <i>Plantago ovata, Phacelia crenulata</i>, and <i>Tiquilia latior</i> occur sporadically. This association typically occurs in drainage channels, on sideslopes, and less commonly in valley bottoms or on badlands at 375 to 675 m (1250-2225 feet) elevation, but can be found as high as 1150 m (3750 feet). It is primarily found on gentle slopes (1-12°), but can also occur on steeper gradients (25-30°), and occurs across all aspects. Soils are mostly well-drained sandy or silty loams derived from various parent materials.  Accession Code: urn:lsid:vegbank.org:commConcept:33919-{7A9FBA53-7F38-4EDA-8230-8698CB3B6FE4} Plot-observations of this Community Concept: 0
