CEGL007883 Crataegus flava - Quercus (incana, laevis) Ruderal Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Yellowleaf Hawthorn - (Bluejack Oak, Turkey Oak) Ruderal Woodland
Colloquial Name: Georgia Sandhills Ruderal Yellowleaf Hawthorn - Scrub Oak Woodland
Hierarchy Level: Association
Type Concept: This association includes highly altered examples of vegetation on sites that were formerly longleaf pine / scrub oak sandhills. It occurs in exposed topographic settings in the Fall-line region of Georgia and possibly adjacent Alabama where fire was an important ecological factor, but where Pinus palustris has been removed or failed to regenerate. Stands are dominated by a variable mixture of Quercus laevis, Quercus incana, and Crataegus flava. Dominance of Crataegus flava and the relative absence of Quercus canopy dominance may occur in areas where fire has been less frequent. Some other woody associates include Pinus taeda, Pinus palustris, Quercus margarettae, Quercus marilandica, Quercus stellata, and Nyssa sylvatica. Shrub and herbaceous associates include Rhus copallinum, Rubus flagellaris?, Toxicodendron pubescens, Andropogon ternarius, Andropogon gyrans, Andropogon virginicus, Schizachyrium scoparium, Cnidoscolus urens var. stimulosus, Danthonia sericea, Eupatorium album, Silphium compositum, Stipulicida setacea, and Pteridium aquilinum var. pseudocaudatum. The density of other strata will depend on site conditions and fire-return interval. Under conditions of extreme fire suppression, canopy closure may be high.

Classification Comments: On Fort Benning, Georgia, this modified vegetation type results from lack of Pinus palustris regeneration and is common in buffer zones surrounding live fire ranges in areas that burn yearly (V. Emrick pers. comm. 1998). In preliminary mapping and surveys at Fort Benning, Georgia, this vegetation type was identified both as a Quercus woodland and a Crataegus shrubland. More information is needed on the substrate(s) on which it is found and its response to management intended to increase the abundance of Pinus palustris. For conservation and restoration purposes, this association should be considered as lower quality (but often highly restorable) examples of one or more communities in a Pinus palustris woodland alliance.

Floristics: Stands are dominated by some combination of Crataegus flava and scrub oaks (e.g., Quercus incana, Quercus laevis). Dominance may vary from Quercus with Crataegus to pure Crataegus. Some other woody associates include Pinus taeda, Pinus palustris, Quercus margarettae, Quercus marilandica, Quercus stellata, and Nyssa sylvatica. Shrub and herbaceous associates include Rhus copallinum, Rubus flagellaris?, Toxicodendron pubescens, Andropogon ternarius, Andropogon gyrans, Andropogon virginicus, Schizachyrium scoparium, Cnidoscolus urens var. stimulosus (= Cnidoscolus stimulosus), Danthonia sericea, Eupatorium album, Silphium compositum, Stipulicida setacea, and Pteridium aquilinum var. pseudocaudatum.
Dynamics: This ecologically modified vegetation type results from lack of Pinus palustris regeneration and is common in buffer zones surrounding live fire ranges in areas that burn yearly, as on Fort Benning, Georgia (Emrick 1998 pers. comm.)
Environmental Description: This association occurs on sites that were formerly longleaf pine / scrub oak sandhills. In these exposed topographic settings in the Fall-line region of Georgia and possibly adjacent Alabama, fire was an important ecological factor, but Pinus palustris has been removed or failed to regenerate.
Geographic Range: Described from the sandhills of the East Gulf Coastal Plain; it could occur in the adjacent Upper East Gulf Coastal Plain.
