Name: Populus fremontii / Mesic Forbs Riparian Woodland Reference: NatureServe Biotics 2019 Description: This riparian woodland association occurs in southeastern Utah. Total vegetation cover ranges from 50% to nearly 100% in these moist woodlands. The vegetation is characterized by an open to moderately closed canopy of <i>Populus fremontii</i> with between 26 and 50% cover. There is no developed shrub layer, although scattered shrubs such as <i>Rosa woodsii</i> and <i>Forestiera pubescens</i> may be present. The herbaceous layer is diverse and provides up to 50% cover, and usually consists several species of forbs. The forb understory varies greatly from site to site and from year to year, depending on the timing of flooding and the height of the water table. Species with significant cover include <i>Oxytenia acerosa, Maianthemum stellatum, Equisetum arvense</i>, and <i>Equisetum laevigatum</i>. Graminoids are low in cover and include <i>Juncus arcticus ssp. littoralis, Phragmites australis</i>, and <i>Schoenoplectus americanus</i>. This riparian woodland occurs along low-gradient perennial and intermittent streams, in mesic valley bottoms and below springs. Although these stands may not flood regularly, the water table is generally within a few feet of the surface through most of the growing season. Sites slope gently (less than 5%) and are located between 1116 and 1890 m (3670-6200 feet) elevation. Soils are typically somewhat poorly drained fine sands in these temporarily flooded sites and are derived from alluvium and colluvium.  Accession Code: urn:lsid:vegbank.org:commConcept:31378-{FFD0D9D4-7100-45D6-9285-1A3B5BB4DFAB} Plot-observations of this Community Concept: 0
