Name: A.53 Reference: EcoArt 2002 Description: This alliance includes dry-mesic to mesic forests of lower and adjacent upper coastal plains. These communities are characteristically dominated or codominated by the evergreen oak ~Quercus hemisphaerica$. Representative examples occur in fire-sheltered topographic situations, or in more fire-prone topographic situations as the result of fire suppression. Soils are typically sandy and nutrient-poor. Examples also occur on nutrient-poor sandy and gravelly sites where the topsoil has been lost due to heavy erosion. These more successional forests on highly eroded nutrient-poor sites may be related to and possibly represent depauperate examples of the ~~Quercus hemisphaerica - Carya glabra$ Forest Alliance (A.372)$$. Other typical tree species in stands of this alliance include ~Pinus taeda, Quercus virginiana, Quercus nigra, Quercus falcata, Magnolia grandiflora, Ilex opaca var. opaca, Carya glabra, Carya pallida$, and ~Carya alba$. Early successional communities in this alliance are likely to be strongly dominated by ~Quercus hemisphaerica$ and to lack (or only have minor amounts of) later successional species, such as ~Carya glabra, Tilia americana var. caroliniana, Carpinus caroliniana ssp. caroliniana, Ostrya virginiana$, and ~Quercus michauxii$. Other characteristic species may include ~Persea borbonia, Persea palustris, Ilex opaca var. opaca, Vitis rotundifolia$, and ~Lyonia lucida$. Examples of this alliance typically occur on submesic to xeric upland sands. The absence of fire is a critical part of the environmental parameters of this alliance; in natural types, this absence of fire results from topographic position. In early successional ruderal types, absence of fire is the result of fragmentation of the landscape and fire suppression in remaining fragments. Dominance by ~Quercus hemisphaerica$ indicates that fire has been excluded from these forests for a period of many years; stands of this species are probably more common and widespread than in pre-settlement times.  Accession Code: VB.CC.2173.A53 Plot-observations of this Community Concept: 0
