Description:
<i>Salix fragilis</i> and <i>Salix alba</i> are large tree willows that were introduced to the United States as ornamental and/or shade trees. These have naturalized along streams and rivers throughout the western U.S. and probably in the western Great Plains. They can reproduce vegetatively and will spread slowly, and usually not far from their source planting. They appear both as individual trees and in large stands. Ecologically they compete with the native tree willows, such as <i>Salix amygdaloides, Salix nigra</i>, and <i>Salix gooddingii</i>, as well as native cottonwoods. Native shrubs such as <i>Salix exigua</i>, and <i>Toxicodendron rydbergii</i> may be present. Understory species include native sedges, grasses and forbs such as <i>Beckmannia syzigachne, Carex aquatilis, Carex utriculata, Carex nebrascensis, Carex hystericina, Calamagrostis</i> spp., <i>Galium</i> spp., <i>Maianthemum stellatum, Mentha arvensis</i>, and <i>Urtica dioica</i>, and others. Non-native herbaceous species can also be abundant, such as <i>Arctium minus, Cynoglossum officinale, Bromus tectorum, Bromus inermis, Poa pratensis, Phleum pratense, Cirsium arvense, Melilotus officinalis, Dactylis glomerata, Conium maculatum</i>, and others. Stands are found in disturbed places, generally near settlements, that are wet naturally or irrigated, such as riparian areas, golf courses, city parks, floodplains, streambanks, ditches and lake margins below 2286 m (7500 feet) in elevation.
