Name: Populus fremontii Seasonally Flooded Woodland Alliance
Reference: Western Ecology Working Group of...
Description: Vegetation types within this alliance occur primarily on relatively flat floodplains (3-5% slope) along low-gradient rivers. Stands are found as gallery forests along perennial or seasonally intermittent streams and springs. They typically occupy the more mesic or hydric areas of the floodplain. Elevations range from 400-2000 m. Soils are derived from alluvial materials, deposited in stratified layers of clays, sands, silts, and gravels. Soil textures are variable but mainly sandy. Surface water is present for extended periods during the growing season, but is absent by the end of the growing season. The water table after flooding ceases is variable, extending from saturated to well below the ground surface. Adjacent upland communities are typically pinyon-juniper or oak shrublands. Communities within this alliance are classified as seasonally flooded woodlands. The canopy is dominated by open stands of Populus fremontii generally forming 30-70% cover. Salix geyeriana commonly occurs in the shrub layer in the Nevada stands. In New Mexico, the herbaceous layer is dominated by Muhlenbergia rigens with 30% cover. No other information on species composition is available.
