Name: Populus angustifolia / Salix exigua Woodland Reference: Western Ecology Working Group of... Description: The type is widespread in mountainous regions of the San Juan, Pecos, and Rio Grande river basins in northern and central New Mexico and widely distributed throughout the Rocky Mountain region and Intermountain West. It is found in wide to narrow valleys at mid- to upper elevations from 1820 to 2360 m (5950-7750 feet). It occurs on streamside alluvial bars that border perennial rivers and intermittent streams of low to moderate gradients (0.7-2.8 %). Sites are typically flooded every five years, sometime more often, and most are within the 25-year floodplain. Stream channel materials are usually coarse and comprised of cobbles or gravel. Soils are young and weakly developed Entisols with wet (aquic) conditions within the top 50 cm or at least within rooting depth. They are well-drained sands and sandy loams mixed with gravels and cobbles. This type is characterized by middle-aged stands of Populus angustifolia in an open upper canopy, with a shrubby understory dominated by Salix exigua. Populus angustifolia saplings (derived from root sprouts) are common beneath the canopy. Other shrubs such as Salix irrorata may be well-represented but clearly subordinate to Salix exigua. The herbaceous layer is very diverse, with 98 species recorded for the type, 23 of which are native wetland indicators.In Colorado, this riparian woodland occupies point bars, gravel bars, benches and low areas that are flooded annually. It is a very common plant community of young seedling and sapling Populus angustifolia intermixed with Salix exigua.  Accession Code: VB.CC.27582.POPULUSANGUSTIF Plot-observations of this Community Concept: 0
