Description: This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the conterminous United States. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps.
Description: The Informational Freshwater Wetland Mapping layer is only intended to be used for informational purposes in identifying the general location and extent of freshwater wetland areas of any size throughout the state. Informational Freshwater Wetland Mapping is not regulatory. The Freshwater Wetlands Act changed in 2022 such that wetlands greater than 12.4 acres in size are regulated regardless of their mapping status. In addition to larger wetlands, the Freshwater Wetlands Act regulates smaller wetlands of “unusual importance” if they meet one of eleven criteria described in the law and regulation. While maps contained on the Environmental Resource Mapper provide information on the potential locations of wetlands, the only definitive way to determine if a particular parcel or property contains regulated wetlands outside the Adirondack Park is to request a jurisdictional determination through DEC’s website (https://dec.ny.gov/nature/waterbodies/wetlands/freshwater-wetlands-program). The Freshwater Wetlands Act regulates most development activities located in the wetland or within a regulated “adjacent area.” This adjacent area is a minimum of 100 feet but may be extended for a limited number of particularly sensitive wetlands. Not all activities in and near wetlands are regulated. There are many exempt activities that landowners may undertake without permits. However, if you are not sure of which activities require permits near New York State regulated wetlands, please contact your regional DEC office.Wetlands are classified from Class I (which provide the most benefits) to Class IV (which provide fewer benefits). The classification is based on the work that wetlands do, such as storing flood water and providing wildlife habitat. The system for classifying wetlands is contained in regulation (6 NYCRR Part 664) and the classification of individual wetlands is determined as part of the jurisdictional determination process.For additional information on NYS Freshwater Wetlands, see DEC's website (https://dec.ny.gov/nature/waterbodies/wetlands/freshwater-wetlands-program).For information on wetlands inside the Adirondack Park, please contact the Adirondack Park Agency.For information on wetlands regulated under federal law, please contact the United State Army Corps of Engineers.Contact for this DataDFW, Bureau of Ecosystem Health625 BroadwayAlbany, NY 12233Phone: 518-402-8920fw.ecohealth@dec.ny.gov
