Name: Populus fremontii / Baccharis salicifolia Woodland Reference: Western Ecology Working Group of... Description: This lowland riparian woodland association is described from southwestern Utah and southwestern New Mexico, and may possibly occur along the San Pedro River in southeastern Arizona. Elevations are below 1580 m in New Mexico and below 1300 m in Utah. Stands typically occur along lower elevation reaches of streams and on the main stem of rivers. Sites are on low- to mid-elevation terraces and bars that are occasionally flooded. Soils are shallow and coarse-textured, composed of sand, gravel or cobbles derived from alluvium. The tree canopy is dominated by the broad-leaved deciduous Populus fremontii. Fraxinus velutina, Platanus wrightii and Salix gooddingii may be present, but are not well represented (<5% cover). The shrub layer is composed primarily of Baccharis salicifolia. Other common associates may include Salix exigua, Prosopis spp. and Ericameria nauseosa (= Chrysothamnus nauseosus). Tamarix ramosissima and Elaeagnus angustifolia are common introduced shrub and tree species that have invaded many of these stands. The herbaceous layer is variable but is generally sparse. Disturbed sites may be dominated by introduced species like Bromus tectorum. Diagnostic of this riparian woodland association is the tree canopy dominated by Populus fremontii with Baccharis salicifolia dominating the shrub layer. Sites have shallow water tables and are flooded for brief periods during the growing season.  Accession Code: VB.CC.18962.POPULUSFREMONTI Plot-observations of this Community Concept: 0
