Name: Symphoricarpos occidentalis Shrubland Reference: NatureServe Biotics 2019 Description: This western snowberry shrubland is found in the western tallgrass, northern Great Plains, and in the foothills of the northern Rocky Mountains of the United States and Canada. Stands occur in mesic depressions and swales, typically surrounded by upland grassland communities. The soils are silts and loams. This type has three distinct vegetation layers, a shrub layer (approximately 80 cm tall), a graminoid-dominated layer (approximately 30 cm tall), and a forb-dominated layer (&lt;20 cm tall). <i>Symphoricarpos occidentalis</i> is the predominant species in the shrub layer and at times forms almost monospecific stands. <i>Rosa woodsii</i> commonly occurs interspersed with the <i>Symphoricarpos occidentalis</i>. Other shrubs, such as <i>Rhus trilobata</i> and <i>Prunus virginiana</i>, often occur as thickets on the fringe of this community. <i>Rhus trilobata</i> and <i>Prunus virginiana</i> can reach 2 m or more. The herbaceous layer is poorly represented where the shrubs are dense, although <i>Poa pratensis</i> occurs in many stands. Common forbs include <i>Artemisia ludoviciana, Solidago</i> spp., and <i>Achillea millefolium</i>. Vines, such as <i>Parthenocissus vitacea</i>, are often found climbing through the shrubs. This type is frequently observed in heavily grazed meadows and prairies.  Accession Code: urn:lsid:vegbank.org:commConcept:30040-{6AB0A28E-55C7-460F-AD20-5B4BCA5AD00A} Plot-observations of this Community Concept: 25
