Abstract:
The key element of the North Carolina
Division of Coastal Managements's (DCM) strategy for improving wetlands protection is the
development of a Wetlands Conservation Plan for the North Carolina coastal area. The
Wetlands Conservation Plan includes a wetland restoration component designed to encourage
proactive wetland restoration efforts and to increase the ecological effectiveness of
compensatory mitigation. A GIS-based, landscape-scale procedure was developed by DCM for
inventorying candidate wetland restoration and enhancement sites in coastal North
Carolina.
Three primary spatial data layers provide information that are
assembled into the DCM restoration and enhancement site data. These layers are the
National Wetlands Inventory (NWI), county soils (DSL), and classified land use/land cover
from TM satellite imagery. The NWI and DSL data are 1:24,000 scale, vector data. The
imagery is 30 meter resolution, filtered and unfiltered, raster data.
A systematic geographic search for wetland restoration and
enhancement sites is a very powerful and useful screening tool for identifying sites with
the greatest ecological potential for performing valuable wetland functions. A GIS
facilitates the inventory process and allows complex analyses of diverse ecological
functions at the landscape level. This methodology is designed to be a decision support
tool, not a decision making tool. It provides an improved and ecologically based approach
to identifying wetland and riparian area Restoration and enhancement sites across river
basins, physiographic regions and other large geographic areas. It does not provide a
substitute for field reconnaissance and on-site evaluations by knowledgeable restoration
specialists.
Purpose:
These data were created to assist local,
state, and federal government agencies and others in making resource management decisions
and in land use planning.

Use_Constraints:
These data are advisory in nature. Although
every effort was taken to ensure the accuracy and validity of restoration and enhancement
site location and extent, these data contain inherent errors and limits. Surfaces mapped
from remotely sensed data have certain degrees of error and accuracy limits. The actual
boundaries may differ from those shown in these data. Sites smaller than one acre often
are overlooked at this scale and may not be included in these data. There also may be
cases in which regulatory agencies' determinations of the existence or lack of wetlands
differ from these data.
While every effort has been made to ensure that these data are
accurate and reliable within limits of the current state of the art, DCM cannot assume
liability for any damages caused by inaccuracies in the map of supporting data. DCM makes
no warranty, express or implied, nor does the fact of distribution constitute such a
warranty.

Attribute_Accuracy:
Attribute_Accuracy_Report:
A comprehensive accuracy assessment of these
data was performed by DCM by visiting 212 potential restoration sites in Carteret, Craven
and Jones counties. Random field points were collected by DCM staff and compared to these
data. For more information see the DCM publication "The Potential Wetland Restoration
and Enhancement Identification Procedure: A Geographic Information System for Targeting
Wetland Restoration".
Logical_Consistency_Report:
These data were originally processed by USGS
7.5 minute quadrangle and by county. Upon completion, all quadrangles and all countyies,
each quadrangle dissolved by the attributes included here and all were joined together
using the Arc/Info "mapjoin" command and then clipped by county. Digital data
and hard copy maps were checked extensively for consistency and completeness by GIS
analysts and wetland specialists on DCM's staff. There may be inconsistencies in these
data along county boundaries. This is due mainly to the fact that the soils data used for
development of this data set were mapped by county and was not edge-matched or otherwise
made consistent at county boundaries.
Completeness_Report:
These wetland functional significance data
represent watersheds completely within the 20 coastal counties under the jurisdiction of
the Division of Coastal Management and an additional 17 counties within the NC Inner
Coastal Plain. The data is not a substitute for an on-site determination of jurisdictional
wetlands. Enhancement and restoration sites smaller than one acre are often overlooked at
this scale and may not be included in these data.

Process_Step:
Process_Description:
Three primary spatial data layers provide
information that are assembled into the DCM restoration site data. These layers are the
National Wetlands Inventory (NWI), county soils (DSL), and classified land use/land cover
from TM satellite imagery. In addition, an update was performed using a more recent
version (1996)of land use/land cover data. The NWI and DSL data are 1:24,000 scale, vector
data. The imagery is 30 meter resolution, filtered and unfiltered, raster data.
The first data set developed by DCM is the wetland type data.
After these data are developed, identification of potential wetland enhancement and
restoration sites can begin. An automated Arc/Info model considers the DCM wetland type,
NWI classification, imagery classification, and soil type in assigning a restoration type
and disturbance class to each polygon. A hydrographic data layer is used in addition to
the layers mentioned previously to more easily interpret the landscape position of the
sites. In addition to automated and manual processing, a limited amount of filed
verification is performed as well.

Entity_and_Attribute_Overview:
Restoration Type Descriptions:
Marsh (rest_type = 1) Salt marshes are typically found along
the margins of sounds and estuaries in low, flat, protected areas which are influenced by
daily tidal flows. Natural vegetation common to salt/brackish marshes include species
which are tolerant of frequent regular flooding and high salt concentrations such as: big
cordgrass (Spartina cynosuroides), saltmarsh cordgrass (Spartina alterniflora), saltmeadow
cordgrass (Spartina patens), sawgrass (Cladium mariscoides), saltgrass (Distichlis
spicata), and black needlerush (Juncus roemerianus). Marsh soils typically have a mucky
surface layer which extends downward 30 to 60 inches thick. These organic soils (Typic
Medisaprists) may be slighlty acid to moderately alkaline.
Estuarine Shrub/Scrub, Estuarine Forest, Estuarine / Maritime
Forest (rest_type = 2) Estuarine Shrub/Scrub/Forest sites are typically located on the
landward margins just above the mean high tide area. These areas are usually irregularly
flooded by wind tides (salt / brackish). Vegetation found in these areas is heavily
influenced by the exposure to salt spray. In areas where salt spray is a factor, species
such as saltmeadow cordgrass, wax myrtle (Myrica cerifera), red cedar (Juniperus
virginiana), eastern baccharis (Baccharis halimifolia), live oak (Quercus virginiana) are
found. In areas where salt spray is not as prevalent vegetation such as black willow
(Salix nigra), redbay (Persea borbonia), blueberry (Vaccinium corymbosum), wild olive
(Osmanthus americana), yaupon (Ilex vomitoria), red maple (Acer rubrum), and loblolly
pine, (Pinus taeda). Maritime Forests sites are usually found on stabilized dune systems
located on the sound-side of barrier islands. Although these areas rarely flood, they are
subjected to constant salt spray, wind shear, and poor soil conditions (low water,
nutrient availability). Vegetation common to these dune swale communities include:
loblolly pine, red maple, live oak, laurel oak (Quercus laurifolia), wax myrtle, redbay,
and red cedar. Soils found on all the above sites are typically mineral and have a sandy
particle size prevalent throughout the limited horizonal development (e.g., Typic
Psammaquents).
Swamp Forest/Bottomland Hardwood (rest_type = 4) Swamp
Forest/BLH sites are found in the floodplains of major rivers and streams and non-riverine
swamp Forests are found in depressional areas. These areas are usually frequently flooded
and/or nearly permanently saturated with groundwater. Vegetation typically found in Swamp
Forests include many water-tolerant hardwoods such as: Bald cypress (Taxodium distichium),
water tupelo (Nyssa aquatica), swamp tupelo (Nyssa sylvatica, var.biflora), and Carolina
ash (Fraxinus caroliniana). Common herbaceous species found include lizards tail (Saururus
cernuus), and arrowhead (Sagittaria sp.). Soils found on Swamp Forest sites may be organic
(Typic Medisaprists) or mineral (Cumulic Humaquepts) and usually contain pockets of sandy
(alluvial) deposits. Bottomland hardwood forests sites are associated with fluvial systems
whose hydrology is primarily controlled by overbank flooding. Vegetation commonly found in
bottomland hardwood forests include: red maple, river birch (Betula nigra), sycamore
(Platanus occidentalis), american elm (Ulmus americana), overcup oak (Quercus lyrata),
green ash (Fraxinus pennsylvanica), and swamp tupelo. Soils common to Bottomland hardwood
sites are typically young mineral soils (Typic Fluvaquents or Humaquepts).
Bottomland Hardwood/Headwater Forest (BLH/Hdwtr) (rest_type =
5) Bottomland hardwood forests sites are associated with fluvial systems whose hydrology
is primarily controlled by overbank flooding. Vegetation commonly found in bottomland
hardwood forests include: red maple, river birch (Betula nigra), sycamore (Platanus
occidentalis), american elm (Ulmus americana), overcup oak (Quercus lyrata), green ash
(Fraxinus pennsylvanica), and swamp tupelo. Soils common to Bottomland hardwood sites are
typically young mineral soils (Typic Fluvaquents or Humaquepts).
Headwater sites are often found along intermittent and/or the
upper end of perennial streams (first order). Headwater sites may be irregularly flooded
by surface runoff although much of the hydrology of headwaters is typically controlled by
seasonally high water tables (groundwater). Species common to headwater forest include:
red maple, sweetgum (Liquidambar styraciflua), loblolly pine, tuliptree (Liriodendron
tulipifera), blackgum (Nyssa sylvatica), and greenbriar (Smilax spp). Soils typical of
Headwater sites often have an upper horizon with significant amounts of organic matter and
an illuvated clay horizon (argillic horizon) (e.g., Typic Humaquults).
Wet Flat (rest_type = 6) Wet Flat sites are located on the
broad, flat (in the Coastal Plain) interstream divides. Typical hydrology for Wet Flats is
controlled by seasonally high water tables from local groundwater input. Local rainfall
may have an impact on the site's hydrology if the area is slightly depressional.
Vegetation common to Wet Flats include: loblolly pine, sweetgum, red maple, willow oak
(Quercus phellos), water oak (Quercus nigra), blackgum, longleaf pine (Pinus palustris),
horsesugar (Symplocos tinctoria), hollies (Ilex spp.), and giant switchcane (Arunidaria
gigantea). Soils of Wet Flatwoods are typically mineral which contain numerous
redoximorphic features (from the fluctuating water table) with a significant clay layer
(s) in the lower horizons (e.g., Typic Paleaquults).
Pocosin (rest_type = 7) Pocosin sites are found on slightly
raised elevations on interstream divides. They also may be found in depressional areas
such as Carolina Bays or swales. Pocosins are dominated by broad-leaved evergreen shrubs.
Vegetation typical of Pocosins include: pond pine (Pinus serotina), sweet bay (Magnolia
virginiana), loblolly bay (Gordonia lasianthus), hollies, blueberry, fetterbush (Lyonia
lucida), sweet pepperbush (Clethra alnifolia), ti-ti (Cyrilla racemiflora), and
laurel-leaf greenbriar (Smilax laurifolia). Soils on Pocosins may either be organic or
mineral. Many of the organic soils of Pocosins have a deep peat layer (Typic Medisaprists)
while the mineral soils typically include a water restrictive (spodic) horizon (e.g.,
Typic Endoaquod).
