Quercus alba - Carya alba Mesic Coastal Plain Forest Alliance

The U.S. National
Vegetation Classification
This alliance includes hardwood forests of the Southeastern Coastal Plain dominated by Quercus alba, frequently with Carya alba. Stands assigned to this alliance are intermediate in moisture status, falling between the more mesic Fagus grandifolia - Quercus alba forests, and drier Quercus forests in which Quercus alba is codominant with Quercus falcata and/or Quercus stellata.

Translated Name:White Oak - Mockernut Hickory Mesic Coastal Plain Forest Alliance
Colloquial Name:Coastal Plain Mesic Oak - Hickory Forest
This alliance includes hardwood forests of the Southeastern Coastal Plain dominated by Quercus alba, frequently with Carya alba. Stands assigned to this alliance are intermediate in moisture status, falling between the more mesic Fagus grandifolia - Quercus alba forests, and drier Quercus forests in which Quercus alba is codominant with Quercus falcata and/or Quercus stellata. These forests are found from the Atlantic Coastal Plain of Virginia and North Carolina, south and west to the Gulf Coastal Plain of Arkansas and Texas, and likely is distributed sparingly in the Piedmont. Forests in this alliance can occur on a variety of sites including sandy swamp islands, coastal plain slopes, ridgetops, and other mesic to dry-mesic fire-sheltered areas on acidic to circumneutral soils.
The combination of Quercus alba, frequently with Carya alba, located in the southeastern coastal plains, distinguishes this alliance.

Range:Examples of this alliance are known from the Atlantic Coastal Plain of Virginia and North Carolina, south and west to the Gulf Coastal Plain of Arkansas, Mississippi, and Texas. One association may range north in the interior to Missouri. It could occur in northern Florida, but none of its component associations have been documented from there. Apparently one association is reported from Delaware, the District of Columbia, Maryland and New Jersey, but this needs to be reviewed.

These are closed-canopy forests with dense and diverse shrub and herbaceous strata.
These hardwood forests are dominated by Quercus alba, frequently with Carya alba. Other canopy trees that may be present include Carya ovata, Carya glabra, Carya illinoinensis, Liquidambar styraciflua, Liriodendron tulipifera, Pinus taeda, Quercus falcata, Quercus nigra, Quercus phellos, Quercus rubra, and Quercus velutina. One association may contain Chamaecyparis thyoides. The subcanopy may include Acer barbatum, Cornus florida, Ilex opaca, Ostrya virginiana, and Oxydendrum arboreum. Shrubs may include Arundinaria gigantea, Asimina triloba, Clethra alnifolia, Gaylussacia frondosa, Hamamelis virginiana, Kalmia latifolia, Lyonia lucida, Symplocos tinctoria, and Vaccinium stamineum. Herbs may have low cover and may include Chasmanthium sessiliflorum, Chimaphila maculata, Cynoglossum virginianum, Mitchella repens, and others.
Forests in this alliance can occur on a variety of sites including sandy swamp islands, coastal plain slopes, ridgetops, and other mesic to dry-mesic fire-sheltered areas on acidic to circumneutral soils.
Low
In the Atlantic Coastal Plain, the sites where this vegetation occurs are somewhat protected from most natural fires by some combination of steeper topography, isolation from the spread of fire, and relatively limited flammability of the vegetation. This different fire regime serves to maintain the compositional distinctiveness relative to adjacent Pinus palustris-dominated stands. If fire does occur, it is likely to be low in intensity and have limited ecological effects. However, there is some evidence that this kind of vegetation has expanded into areas once occupied by Pinus palustris as fire has become less frequent or absent in parts of the landscape. If fire was more frequent, the predominant vegetation would shift toward more fire-tolerant southern pines, especially Pinus palustris. The characteristic and dominant trees are capable of living for several centuries, and these forests probably were present in the presettlement landscape as old-growth stands, with canopy dynamics dominated by gap-phase regeneration. Small to medium-sized canopy gaps created by wind are the primary natural disturbance at present, and probably were in the past as well. Fire likely created some small to medium-sized gaps in the past also, and likely caused all canopy gaps to persist longer. However, exposure to occasional fires and hurricanes in the coastal plain may create more frequent and larger canopy disturbances than more inland examples.

About spatial standards:
The United States Federal Geographic Data Committee (hereafter called the FGDC) is tasked to develop geospatial data standards that will enable sharing of spatial data among producers and users and support the growing National Spatial Data Infrastructure (NSDI), acting under the Office of Management Budget (OMB) Circular A-16 (OMB 1990, 2000) and Executive Order #12906 (Clinton 1994) as amended by Executive Order #13286 (Bush 2003). FGDC subcommittees and working groups, in consultation and cooperation with state, local, tribal, private, academic, and international communities, develop standards for the content, quality, and transferability of geospatial data. FGDC standards are developed through a structured process, integrated with one another to the extent possible, supportable by the current vendor community (but are independent of specific technologies), and publicly available.

About this document
This document contains type descriptions at the Alliance level of the U.S. National Vegetation Classification. These descriptions were primarily written by NatureServe ecologists in collaboration with Federal Geographic Data Committee Vegetation Subcommittee and a wide variety of state, federal and private partners as a part of the implementation of the National Vegetation Classification. Formation descriptions were written by the Hierarchy Revisions Working Group. The descriptions are based on consultation with natural resource professionals, published literature, and other vegetation classification systems. The Ecological Society of America's Panel on Vegetation Classification is responsible for managing the review and formal adoption of these types into the National Vegetation Classification. Partners involved in the implementation of the USNVC include:

  • Department of Commerce (DOC)
  • Department of Defense (DOD)
  • Department of the Interior (USDI)

Disclaimer:
Given the dynamic nature of the standard, it is possible a type description is incomplete or in revision at the time of download; therefore, users of the data should track the date of access and read the revisions section of the USNVC.org website to understand the current status of the classification. While USNVC data have undergone substantial review prior to posting, it is possible that some errors or inaccuracies have remained undetected.
