This dataset contains only those wetlands regulated by the New York State Freshwater Wetlands Act. It does not necessarily contain wetlands regulated by other jurisdictions or unregulated wetlands, nor does it contain tidal wetlands regulated by New York State under the Tidal Wetlands Act (ECL Article 25).This dataset was originally composed of a set of ARC/INFO coverages containing both polygonal and linear features. The Coverages are based on official New York State Freshwater Wetlands Maps as described in Article 24-0301 of the Environmental Conservation Law. Coverages are not, however, a legal substitute for the official maps. Coverages are available on a county basis for all areas of New York State outside the Adirondack Park. The coverage for Columbia County incorporates proposed amendments which became the official regulatory wetland boundaries as of November 30, 2011 and March 5, 2013.An important feature of the official maps is that the lines indicate only "the approximate location of the actual boundaries of the wetlands" (ECL Section 24-0301(3)). For a final determination of the actual location of a wetland it is necessary to contact the NYSDEC office for the region in which the wetland occurs.Columbia County is in Region 4.

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 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.View Dataset on the GatewayFor 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.

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).

This dataset depicts 100 foot buffers of wetlands regulated by the New York State Freshwater Wetlands Act. It does not contain buffers of wetlands regulated by other jurisdictions or unregulated wetlands, nor does it contain buffers of tidal wetlands regulated by New York State under the Tidal Wetlands Act (ECL Article 25).An important feature of the official NYS wetland maps is that the lines indicate only "the approximate location of the actual boundaries of the wetlands" (ECL Section 24-0301(3)). Therefore, the buffers represented in this dataset should also be considered approximate. For a final determination of the actual location of a wetland and the 100 foot regulatory area surrounding it, it is necessary to contact the NYSDEC office for the region in which the wetland occurs.Columbia County is in Region 4.

This product is a satellite-based habitat map time series from 2012 to 2020 for the Whiskey Island reach of the Louisiana Gulf shoreline to facilitate monitoring of the Natural Resource Damage Assessment (NRDA) Caillou Lake Headlands project area (TE-0100), also known as Whiskey Island. The project created 170 acres of marsh habitat and 917 acres of dune and beach habitat on Whiskey Island in Terrebonne Parish, Louisiana, using material dredged from Ship Shoal. For more information on this restoration project, see the project page on Louisiana Coastal Protection and Restoration Authority’s (CPRA) Coastal Information Management System (https://cims.coastal.la.gov/outreach/projects/ProjectView?projID=TE-0100). The time period for these maps spans before, during, and after the restoration project. Maps were produced using a random forest model that classified cover types (that is, bare, herbaceous vegetation, woody vegetation, and water) based on spectral indices from Sentinel-2 and ...

This dataset represents wetlands included in Vermont's Significant Wetlands Inventory (WaterWetlands_VSWI). Questions about wetland location and use should be referred to the ANR DEC Wetlands section, 802-244-6951. NWI maps were used by the State of Vermont Agency of Natural resources as a means of creating this data layer in conjunction with the VSWI. The NWI and VSWI were joined by a union, to create the new 2010 Vermont Significant Wetland Inventory data layer, representing Vermont's regulatory wetlands. The VSWI prior to 2010 was created by hand digitizing nearly two-thirds of Vermont's wetlands from RF 24000 scale NWI mylars. The remainder of the state was scanned from RF 24000 or RF 25000 scale mylars.These mylars were created by transfering wetland polygon boundaries from RF 62500 scale NWI mylars to RF 24000 scale base maps.

The State of Vermont, in partnership with 25 organizations, agencies, businesses and non-profits, received funding in 2015 from the U.S. Department of Agriculture’s Natural Resources Conservation Service (NRCS) through the Regional Conservation Partnership Program (RCPP). This $16 million grant was the second largest in the country and is helping landowners in the Lake Champlain Basin of Vermont and New York invest in best conservation practices to improve water quality. The Lake Champlain RCPP provides financial and technical assistance to agricultural and forest landowners to develop and implement site-specific farm and forest projects that will directly improve water quality in streams and rivers that flow towards Lake Champlain. The RCPP funds will also help conserve important and environmentally critical agricultural lands, and restore and protect wetlands crucial to attenuating sediment and nutrients and slowing floodwaters. These funds are committed through 2020, but may be extended, or new sources made available, in the future.

The Wetland Restoration Model Site Prioritization Map (this layer) builds on a model initially developed in 2007 ranked potential wetland restoration sites based on various physical characteristics of an area. For more information, read the RCPP Wetland Restoration Site Prioritization Project Map Introduction document.

West Virginia Wetlands Inventory is a record of wetlands location and classification as defined by the National Wetlands Inventory (NWI) of the U.S. Fish and Wildlife Service. This dataset is available as a single statewide coverage. The data provide consultants, planners, and resource managers with information on wetland location and type; however, not all wetlands are mapped as explained under “data limitations” below.

The originator of the inventory is the WV Department of Environmental Protection in coordination with the U.S. Fish and Wildlife Service. Time period of content ranges from Feb. 1971 to Dec. 1992, with updates to 6% of the data in 2018. Wetland point, line and area features are compiled through manual photo interpretation of aerial photography supplemented by soil surveys, digital elevation data, and field checking.
