click to update datacart
Name: Populus fremontii / Artemisia tridentata Riparian Woodland Reference: NatureServe Biotics 2019 Description: This deciduous woodland association occurs on the Colorado Plateau on upper stream terraces and the banks of dry washes in valleys and canyon bottoms between 1220 and 1355 m elevation. These sites may flood occasionally but are located high above the water table during the growing season. Sites are generally flat with one known stand occurring on a sloping terrace. Litter covers most of the unvegetated surface with bare ground and downed wood covering the rest. Soils are rapidly drained to well-drained sandy loams derived from alluvium. The vegetation is characterized by an open to relatively closed canopy, typically 10-15 m tall, of mature to decadent <i>Populus fremontii</i> trees with up to 30% cover. The subcanopy layer, if present, includes smaller <i>Populus fremontii</i> and <i>Salix gooddingii</i> trees, and occasional <i>Juniperus osteosperma</i> may be present. <i>Artemisia tridentata ssp. tridentata</i> dominates or codominates the understory, although cover may be as low as 4%. Low cover of associated shrub species may be diverse and include <i>Ericameria nauseosa, Purshia stansburiana, Rhus trilobata, Rosa woodsii, Salix exigua, Sarcobatus vermiculatus</i>, and the vine <i>Clematis ligusticifolia</i>. Exotic shrub <i>Tamarix chinensis</i> is present in some stands. The herbaceous layer is generally diverse in terms of species composition, includes a number of exotic species, and provides sparse to moderate cover.  Accession Code: urn:lsid:vegbank.org:commConcept:34125-{75887BE1-EEB9-45CC-B887-EF62B0361E00} Plot-observations of this Community Concept: 0
