Name: Populus fremontii / Mesic Forbs Woodland Reference: Western Ecology Working Group of... Description: This woodland association is documented along low-gradient perennial and intermittent streams, in mesic valley bottoms and below springs in southeastern Utah. Although these stands may not occur on sites that 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 1530 and 1890 m (5020-6200 feet) elevation. Soils are typically somewhat poorly drained fine sands in these temporarily flooded sites and are derived from alluvium and colluvium. 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> and the exotic shrub <i>Tamarix chinensis</i> may be present. The herbaceous layer is diverse and provides up to 50% cover. 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. Documented species with significant cover include <i>Iva acerosa, Maianthemum stellatum, Equisetum arvense</i>, and <i>Equisetum laevigatum</i>. Graminoids are low in cover and include <i>Juncus balticus, Phragmites australis</i>, and <i>Schoenoplectus americanus</i>.  Accession Code: VB.CC.31118.CEGL002470 Plot-observations of this Community Concept: 0
