Solidago canadensis - Securigera varia 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 community is characterized by a moderately open to dense herbaceous stratum (avg. cover 85%) dominated by exotic and weedy native forbs. There may be shrubs and trees present but they are either very short or have less than 25% cover. Common herbaceous species vary depending on past site use, seed sources, and other factors but forbs often include <i>Ambrosia artemisiifolia, Arctium minus, Berteroa incana, Cirsium arvense, Conyza canadensis, Securigera varia, Galium aparine, Melilotus officinalis, Monarda fistulosa, Rudbeckia hirta, Solidago canadensis, Trifolium pratense</i>, and <i>Verbascum thapsus</i>. Graminoids can be common and often include <i>Bromus inermis, Panicum capillare, Poa pratensis, Setaria viridis</i>, and others. The shrubs and small trees than can be present are usually exotic or generalist native species, much like the herbaceous layer. <i>Acer negundo</i> and <i>Populus deltoides</i> can be present, typically as short trees, along with the shrubs <i>Lonicera</i> spp., <i>Rhamnus cathartica, Rubus</i> spp., and <i>Zanthoxylum americanum</i>. This ruderal community is found on a variety of soils but is usually on flat to moderately sloping sites. The ground is mostly bare soil (avg. 72%) with some plant litter (avg. 13%). The common factor affecting this community is a history of extensive disturbance from agricultural or urban development activities that result in a site strongly dominated by exotic or weedy native forbs.
