Today there is great interest in managing wetland resources from a watershed standpoint or landscape perspective. Wetland managers need information on a variety of topics including the location and type of existing wetlands, wetland functions, potential wetland restoration sites, and the overall condition of natural habitat in the watershed. The U.S. Fish and Wildlife Service's National Wetlands Inventory Program has developed products that expand the use of its conventional maps and digital products to aid in resource management. The Delaware Department of Natural Resources and Environmental Control (DNREC) is attempting to reduce nonpoint source pollution impacts in the Nanticoke watershed and wanted the above information for the Delaware portion of the Nanticoke River watershed. This information would be used to help improve water quality and management and conservation of fish and wildlife habitat in wetlands, streams, riparian areas, and uplands in Delaware. Similar work has recently been completed for the Maryland portion of the watershed (Tiner et al. 2000). In the future, both efforts may be combined into a single report.
