Name: Populus fremontii / Mesic Graminoids Woodland Reference: Western Ecology Working Group of... Description: This woodland association occurs on the banks of intermittent and perennial streams, in seepy areas on valley bottoms and in active floodplains in southeastern Utah. Flooding occurs irregularly, but the water table remains within a few feet of the surface throughout the growing season. Stands are located on gently sloping (less than 5%) sites between 1438 and 1768 m (4715-5800 feet) elevation. Soils are typically somewhat poorly drained fine sands derived from alluvium. Total vegetation cover generally exceeds 50%. The vegetation is characterized by an open canopy of <i>Populus fremontii</i> trees that range in cover from 25 to 40%, although cover in some stands may be as high as 80%. There is no developed shrub layer, although scattered individuals of shrubs such as <i>Salix exigua, Salix lutea, Ericameria nauseosa</i>, and <i>Artemisia tridentata ssp. tridentata</i> may be present, and the exotic shrub <i>Tamarix chinensis</i> is often present. The herbaceous layer is constant only in that it is dominated by graminoids; otherwise it varies greatly in composition and cover from site to site and from year to year, depending on the flooding regime and the height of the water table. No species is characteristic of this type, but significant species recorded from sampled sites include <i>Equisetum</i> spp., <i>Juncus balticus, Juncus ensifolius, Muhlenbergia asperifolia</i>, and <i>Polypogon viridis</i>. Forbs are present but are inconsistent and provide low cover.  Accession Code: VB.CC.31124.CEGL002473 Plot-observations of this Community Concept: 0
