Name:
Andropogon virginicus - Rubus spp. - Ambrosia artemisiifolia Southeastern Ruderal Grassland & Shrubland Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This macrogroup comprises vegetation that occurs on sites that were cleared and the soils disturbed (e.g., old fields, abandoned quarries, old homesteads, etc.), or the vegetation otherwise heavily disturbed, e.g., through heavy grazing, such that the vegetation has a distinct composition and structure from other more native vegetation types. The stands may be composed of weedy generalist native or exotic species, or combinations of these. In the southeastern Piedmont, the herbs and grasses that dominate old fields undergo a rapid turnover in the first three years after abandonment. By the third year, <i>Andropogon virginicus</i> often is the dominant plant. Before it achieves dominance, <i>Ambrosia artemisiifolia, Conyza canadensis, Digitaria sanguinalis</i>, and <i>Symphyotrichum pilosum</i> may be more prominent. Other perennial grasses may include <i>Andropogon gyrans, Andropogon ternarius</i>, and <i>Dichanthelium dichotomum</i>. Shrubs and vines may be present or dominant, including the native genera <i>Baccharis, Cornus, Prunus</i>, and <i>Rubus</i>, as well as the exotics <i>Ligustrum</i> spp., <i>Pueraria montana var. lobata</i>, and <i>Wisteria sinensis</i>. In the absence of disturbance, small trees rapidly overtake the sites and may become dominant.
