Name:
Quercus (margarettiae, stellata) - Quercus marilandica / Crataegus flava / Schizachyrium scoparium Woodland
Reference:
Southeastern Ecology Working Gro...
Description:
This association covers open-canopy stands dominated by <i>Quercus margarettiae, Carya pallida, Quercus stellata</i>, and/or <i>Quercus marilandica</i> in the sandhills of the East Gulf Coastal Plain of Georgia and possibly adjacent and nearby Alabama, or in the sandhills of the South Atlantic Coastal Plain. Some stands can approach closed canopy (>60% canopy closure). These woodland stands are presumably modified and/or fire-suppressed examples of <i>Pinus palustris</i>-dominated or <i>Pinus palustris - Quercus</i> spp.-dominated vegetation where <i>Pinus palustris</i> has been removed or failed to regenerate. Stands of this vegetation occur in exposed topographic settings on gentle to somewhat steeply sloped, northerly aspect hills in the Fall-line region of Georgia and possibly adjacent Alabama where fire was a common natural disturbance, but where its importance has been reduced. Inclusions of xeric vegetation including <i>Quercus laevis, Quercus incana</i>, and <i>Crataegus flava</i> increase in prevalence at high slope and ridgetop positions in these slope woodlands, while more mesic components increase at lowslope positions (e.g., <i>Quercus falcata</i>). Some woody associates include <i>Pinus taeda, Pinus palustris, Quercus falcata, Quercus incana, Quercus laevis, Cornus florida</i>, and <i>Nyssa sylvatica</i>. Shrub components include <i>Vaccinium arboreum, Vaccinium stamineum, Crataegus flava, Rhus copallinum, Rubus cuneifolius, Rubus trivialis, Rubus flagellaris</i>?, and <i>Toxicodendron radicans</i>. The grass-dominated herbaceous stratum contains <i>Andropogon virginicus, Schizachyrium scoparium, Aristida purpurascens, Danthonia sericea, Cnidoscolus stimulosus, Amsonia ciliata, Aureolaria pectinata, Eriogonum tomentosum, Vernonia angustifolia, Pityopsis aspera, Eupatorium</i> spp., <i>Silphium</i> spp., and <i>Pteridium aquilinum</i>. The relative density of the strata will depend on site conditions and fire-return interval. Under conditions of extreme fire suppression, the structure may approach that of a forest (i.e., greater than 60% canopy closure). It is presently unclear why these stands are not dominated instead by <i>Quercus laevis</i> (e.g., examples of ~<i>Crataegus flava - Quercus (incana, laevis) </i>Semi-natural Woodland (CEGL007883)$$).
