Name: Populus deltoides (ssp. wislizeni, ssp. monilifera) / Pascopyrum smithii Riparian Woodland Reference: NatureServe Biotics 2019 Description: This association represents riparian woodlands on the Great Plains of eastern Wyoming, southeastern Utah and possibly eastern Montana, the western Dakotas and Nebraska. Stands have been documented in Wyoming from 1143 to 1387 m (3750-4550 feet) elevation, primarily along small streams (&lt;50 feet wide), on alluvial soils in a range of textural classes. The vegetation is simple in structure. <i>Populus deltoides</i> dominates a tree overstory that may consist of scattered large trees in old stands or of denser, small or -medium-sized trees in younger stands. Scattered shrubs may be present. The herbaceous undergrowth is composed of short or mid-height grasses and forbs; <i>Pascopyrum smithii</i> contributes as much canopy cover to the undergrowth as does any other native species. As with other <i>Populus deltoides</i> woodlands, stands of this association generally are early- to mid-seral; <i>Populus deltoides</i> seedlings become established on bare sediment bars laid down by flood waters, and trees in the even-aged overstory are not replaced by younger cottonwoods as they age and die. Several different <i>Populus deltoides</i> associations share a number of plant species in the herbaceous undergrowth (including <i>Pascopyrum smithii</i>), and this association contains the woodlands in which <i>Pascopyrum smithii</i> contributes at least as much cover as does any other native graminoid.  Accession Code: urn:lsid:vegbank.org:commConcept:31588-{BF14CD63-754E-409A-A6B4-79A8E5E7FCC9} Plot-observations of this Community Concept: 0
