Name: Poa pratensis - Bromus inermis Ruderal Meadow Reference: NatureServe Biotics 2019 Description: This association is currently only described from Mississippi National River and Recreation Area, Minnesota. Additional global information will be added as it becomes available. This association is characterized by strong dominance by exotic grasses &lt;1 m tall. The herbaceous stratum is moderate to dense (avg. 80%) and may have scattered trees and shrubs above it but those lifeforms have &lt;25% cover. This association often results from planting or the spread of planted species from nearby areas. Most sites are dominated by the perennials <i>Bromus inermis</i> or <i>Poa pratensis</i>. <i>Elymus repens</i> may be abundant. Annual grasses can be abundant or even dominant in some stands, among these <i>Digitaria</i> spp. and <i>Setaria</i> spp. are the most common. Forb cover ranges from very sparse to high but is always less than the grass cover. Common forbs tend to be exotic or weedy natives, including <i>Ambrosia artemisiifolia, Asclepias verticillata, Berteroa incana, Centaurea stoebe ssp. micranthos, Cirsium arvense, Securigera varia, Melilotus officinalis, Rudbeckia hirta, Solidago canadensis, Trifolium</i> spp., and <i>Verbascum thapsus</i>. Shrubs and trees that are present reflect the open, often disturbed nature of the sites and include <i>Lonicera</i> spp., <i>Prunus virginiana, Rhus</i> spp., <i>Rubus</i> spp., and <i>Ulmus pumila</i>. This association occurs on a variety of landforms, slopes, and soil types. The common factor to all sites is a history of significant anthropogenic disturbance, often including planting of exotic species. Sites are found on flat to steep slopes and mostly on medium-textured soils but coarse or fine soils are possible. Sites range from wet-mesic to dry-mesic. Dead plants, both standing and in the form of litter on the ground, are common. Plant litter had an average of 73% cover and bare ground only 5% cover.  Accession Code: urn:lsid:vegbank.org:commConcept:34216-{548F8F9F-A33E-4B06-8FB7-1E78F9ADF372} Plot-observations of this Community Concept: 0
