Populus deltoides ssp. wislizeni / Salix irrorata Flooded Forest | NatureServe Biotics 2019

Name: Populus deltoides ssp. wislizeni / Salix irrorata Flooded Forest Reference: NatureServe Biotics 2019 Description: This lower-montane riparian association is known from small tributaries of the Rio Grande in northern New Mexico. Also, within Bandelier National Monument, this association occurs along a canyon bottom with low solar exposure. It occurs on narrow valley bottom alluvial sediments with low to moderate gradients. Flooding is estimated to occur on a 10-year return interval or less. Elevations range from 1525 to 1900 m (5000-6250 feet). Stands occur on alluvial terraces and bars adjacent to perennial stream channels with gradients less than 10%. The substrates are alluvial deposits derived from basalt and andesite volcanics. The ground surface is characterized by shrubs rooted among rhizomatous grasses, exposed gravels and soil-intermixed litter patches. Stands are dominated by <i>Populus deltoides ssp. wislizeni</i> with moderately open canopies along with scattered <i>Acer negundo, Juniperus monosperma</i>, and <i>Juniperus scopulorum</i>. The undergrowth is characterized by thickets of <i>Salix irrorata</i> and a diverse complement of grasses and forbs. As a keystone species, the reproduction of <i>Populus deltoides</i> after flooding (and sufficient subsequent base flows) is critical to the sustainability of this community.  Accession Code: urn:lsid:vegbank.org:commConcept:34645-{2BB99A5A-381B-4848-AA06-63A60A366B44} Plot-observations of this Community Concept: 0
