The Division of Coastal Management identified the need for a
Wetlands Conservation Plan in 1992, when it found that the state could not determine the
amount, type, location, functions and loss/gain trends of freshwater wetlands in the 20
coastal counties.
Unlike saltwater and brackish tidal wetlands, known as coastal
wetlands, these non-tidal, freshwater wetlands were not specifically protected under North
Carolina law or regulation at the time.* Yet freshwater wetlands serve important roles in
water quality, floodwater control and wildlife habitat; and damage to freshwater wetlands
can affect salt waters down stream.
To address these weaknesses, DCM has developed a Wetlands Conservation Plan for the
North Carolina coastal area. The primary purpose of the plan is to provide detailed
wetland information to local, state and federal governments, businesses, nonprofit
organizations and the public, so they can make better resource management decisions.
The Wetlands Conservation Plan has several components:
DCM has completed its wetlands inventory, using an
extensive geographic information systems (GIS)-based wetlands mapping program. Using the
GIS coverage, DCM can generate maps showing wetland locations and types.
The functional assessment (called NC-CREWS -
North Carolina Coastal Region Evaluation of Wetland Significance) examines the ecological
significance of wetlands. DCM makes this assessment using a a GIS-based landscape analysis
of each wetland in a watershed. The analysis evaluates the contribution each wetland has
to water quality, hydrology and wildlife habitat, and the risk to the watershed integrity
should a wetland be removed.
Wetland restoration, agency coordination, coastal area wetland policies and
land-use planning all are means by which the wetlands maps and functional
assessment will be used to improve wetland protection and management.
The results of the functional assessment will provide additional information about the
ecological significance of wetlands in each coastal county. This information will help
regulatory agencies determine the importance of protecting a particular wetland site in
the event a fill permit is requested. It will also enable development projects to be
planned so as to avoid, at all reasonable cost, the most ecologically important wetlands.
* The Division of Water Quality's (DWQ) 1996 Wetland Water
Quality Standards provide some protection of wetlands now. DWQ began to use these
standards in March 1999 to protect wetlands from filling activities that violated the
standards. |
