Dactylis glomerata - Solidago canadensis - Rosa multiflora Eastern North American Ruderal Grassland & Shrubland Macrogroup
Reference:
NatureServe Biotics 2019
Description:
These ruderal grasslands and shrublands encompass sites in the northern and central regions of the eastern United States that have been cleared and plowed (for farming or development) and then abandoned, and are now are dominated by weedy or generalist native and exotic forbs, grasses, ferns, and shrubs. There are three variants of this vegetation, each of which has its own characteristic herbs and shrubs. The better known variants are the "mesic open old-field meadow variant" and the "mesic old-field shrubland variant." There are also dry variants which are less well-described. The mesic open old-field meadow variant has characteristic forbs that include <i>Asclepias syriaca, Centaurea stoebe ssp. micranthos, Cerastium arvense, Daucus carota, Euthamia graminifolia, Fragaria virginiana, Oenothera biennis, Picris hieracioides, Potentilla simplex, Rudbeckia hirta, Solidago altissima, Solidago canadensis, Solidago juncea, Solidago nemoralis, Solidago rugosa, Symphyotrichum lateriflorum</i>, and <i>Symphyotrichum novae-angliae</i>. Common grasses include <i>Anthoxanthum odoratum, Bromus inermis, Dactylis glomerata, Elymus repens, Lolium</i> spp., <i>Phleum pratense, Poa compressa</i>, and <i>Poa pratensis</i>. Shrubs may be present, but collectively they have less than 25% cover. Characteristic shrubs in this variant include those of the mesic shrub variant. The mesic old-field shrubland variant is typically dominated by <i>Amelanchier</i> spp., <i>Cornus racemosa, Cornus sericea, Crataegus</i> spp., <i>Juniperus virginiana, Prunus americana, Prunus virginiana, Rhus glabra, Rhus typhina, Rubus</i> spp., <i>Rubus</i> spp., <i>Viburnum lentago</i>, and <i>Viburnum recognitum</i>. The exotic shrubs <i>Elaeagnus angustifolia, Lonicera</i> spp., and <i>Rosa multiflora</i> may be invasive in some areas. The dry old-field grassland and shrubland variant is found on sandy or rocky substrates and is typically dominated by <i>Andropogon virginicus, Poa compressa, Schizachyrium scoparium, Solidago nemoralis</i>, and an assortment of dry weedy species such as the exotic <i>Centaurea stoebe ssp. micranthos</i>. Scattered native or exotic trees may be present, including <i>Acer rubrum, Fraxinus pennsylvanica, Pinus rigida, Pinus strobus, Pinus sylvestris</i>, and <i>Populus deltoides</i>.
