(Link to Metadata) VCGI downloaded NWI quads from the US FWS web site and reprojected to VCS NAD83. NWI digital data files are records of wetlands location and classification as developed by the U.S. Fish & Wildlife Service. This dataset is one of a series available in 7.5 minute by 7.5 minute blocks containing ground planimetric coordinates of wetlands point, line, and polygon features and wetlands attributes. When completed, the series will provide coverage for all of the contiguous United States, Hawaii, Alaska, and U.S. protectorates in the Pacific and Caribbean. Coverage includes both digital data and hardcopy maps. The NWI maps do not show all wetlands since the maps are derived from aerial photointerpretation with varying limitations due to scale, photo quality, inventory techniques, and other factors. Consequently, the maps tend to show wetlands that are readily photointerpreted given consideration of photo and map scale. In general, the older NWI maps prepared from 1970s-era black and white photography (1:80,000 scale) tend to be very conservative, with many forested and drier-end emergent wetlands (e.g., wet meadows) not mapped. Maps derived from color infrared photography tend to yield more accurate results except when this photography was captured during a dry year, making wetland identification equally difficult. Proper use of NWI maps therefore requires knowledge of the inherent limitations of this mapping. It is suggested that users also consult other information to aid in wetland detection, such as U.S. Department of Agriculture soil survey reports and other wetland maps that may have been produced by state and local governments, and not rely solely on NWI maps. See section on "Completeness_Report" for more information. Also see an article in the National Wetlands Newsletter (March-April 1997; Vol. 19/2, pp. 5-12) entitled "NWI Maps: What They Tell Us" (a free copy of this article can be ordered from U.S. Fish and Wildlife Service, ES-NWI, 300 Westgate Center Drive, Hadley, MA 01035, telephone, 413-253-8620).

This dataset represents wetlands included in Vermont's Significant Wetlands Inventory. The State of Vermont protects wetlands which provide significant functions and values and also protects a buffer zone directly adjacent to significant wetlands. Wetlands in Vermont are classified as Class I, II, or III based on the significance of the functions and values they provide. Class I and Class II wetlands provide significant functions and values and are protected by the Vermont Wetland Rules. Any activity within a Class I or II wetland or buffer zone which is not exempt or considered an "allowed use" under the Vermont Wetland Rules requires a permit.Background: National Wetlands Inventory (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 Vermont Wetlands Program is responsible for identifying and protecting wetlands and the functions and values they provide by the implementation of the Vermont Wetland Rules.

Please note that NWI data is continuously being improved and new data is added on a biannual basis. Those updates are reflected on the Wetlands Mapper and in the data downloads in October and May of each year. To ensure that you have the most up to date information, please refer to the published date in the metadata, the location of new data on the Projects Mapper and download new data regularly.Each State data download is available as either a compressed file Geodatabase or a Shapefile (PDF). Both files are compressed by using the .zip format and contain the following layers:Wetlands polygon data - Version 2Wetlands Project Metadata - Version 2 (includes image dates and project information)Wetlands Historic Map Information*Riparian polygon data*Riparian Project Metadata (includes image dates and project information)*Historic Wetlands*Historic Wetlands Project Metadata (includes image dates and project information)*Watershed Boundary Dataset (WBD) HUC8 modified*** If available at the requested location.** Not include in State downloads.The state downloads include a Wetlands Project Metadata layer that identifies where and when wetlands were mapped within the state.NOTE: Due to the variation in use and analysis of this data by the end user, each of states wetlands data extends beyond the state boundary. Each state includes wetlands data that intersect the 1:24,000 quadrangles that contain part of that state (1:2,000,000 source data). This allows the user to clip the data to their specific analysis datasets. Beware that two adjacent states will contain some of the same data along their borders.

Download In State Plane Projection Here The Lake County Wetland Inventory (LCWI) maps natural and artificial wetlands meeting definitions established by the federal agencies who work with the Lake County Geographic Information System staff to periodically review and update it. These agencies include the United States Environmental Protection Agency, the U.S. Fish and Wildlife Service, the USDA Natural Resources Conservation Service and the United States Army Corps of Engineers. The 1989 federal wetland delineation standards for offsite wetland mapping are used. This data was last published in March of 1993. This update includes changes to the previous version of LCWI including: adjust current wetland boundaries to omit development, including roads; to fine tune boundary placement where that was intended by the original delineation, in some cases, adjust the wetland to photographic features / signature; delete wetlands which the committee decided were mapped in error - for example, trees which were mistaken for wet areas; create polygons for newly delineated artificial wetlands; and newly delineated wetlands or farmed wetlands caused by the continued deterioration of the agricultural drain tile system and increased runoff due to urbanization. The LCWI is a useful tool for general planning and review purposes, but it does not take the place of an on-site delineation by a certified wetland specialist. High resolution (1" = 100') orthorectified aerial imagery captured in April 2002 was used as the base for this update. Other data used as reference for this update include: 2004 SOIL SURVEY GEOGRAPHIC (SSURGO) DATABASE FOR LAKE COUNTY, IL - U.S. Department of Agriculture, Natural Resources Conservation Service; HYDROLOGY2002 - Lake County GIS/Map Division; 2' topography (CONTOURS) - Lake County GIS/Map Division; and various years of historical aerial photography for clarification. By using the more recent higher resolution photography, the resulting updated wetland boundaries are more accurate then the original boundaries published in 1993.

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.

The Los Angeles County, CA Meter Urban Land Cover (MULC) dataset was generated from sub-meter image pixel resolution data created by the University of Vermont Spatial Analysis Laboratory (SAL) through the combined use of 2016 USDA National Agricultural Imagery Program (NAIP) four band (red, green, blue and near infrared) aerial imagery, 2016 LiDAR data and 2014 ortho-imagery. The sub-meter, thematic landcover data feature attributes were recoded and spatially resampled to a 1-meter spatial scale by EPA for MULC data product integration. The mapped area is confined to the boundaries of US Census Bureau's 2010 Urban Statistical Area for Los Angeles County, with an added 1km coastal water buffer area extension. The following eight land cover classes were mapped: Water, Impervious, Soil or Barren, Trees or Forest, Grass or Herbaceous, Woody Wetlands and Emergent Wetlands. Integrated wetland features were derived using ancillary National Wetlands Inventory (NWI) polygon data (version 2), downloaded from the Unites States Fish and Wildlife Service (USFWS) Wetland Mapper web mapping service (https://www.fws.gov/wetlands/data/mapper.html). Metadata for the NWI wetlands data layer can be found at http://www.fws.gov/wetlands/Data/Metadata.html. An accuracy assessment of the classified product, using 887 completely random and 40 stratified random photo-interpreted land cover reference sample points yielded an overall user's accuracy (MAX) of 61.1 percent and a fuzzy user's accuracy (RIGHT) of 89.2 percent. For data workflow processing details see Overview Description section. This dataset was produced by the University of Vermont Spatial Analysis Laboratory, the United States Forest Service Urban Tree Canopy (UTC) assessment program, and the US EPA to support research and online mapping activities related to the EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).

The New York, NY EnviroAtlas Meter-scale Urban Land Cover (MULC) Data were generated by the University of Vermont Spatial Analysis Laboratory (SAL) under the direction of Jarlath O'Neil-Dunne as part of the United States Forest Service Urban Tree Canopy (UTC) assessment program. Seven classes were mapped using LiDAR and high resolution orthophotography: Tree Canopy, Grass/Shrub, Bare Soil, Water, Buildings, Roads/Railroads, and Other Paved Surfaces. These data were subsequently merged to fit with the EPA classification. The SAL project covered the five boroughs within the NYC city limits. However the EPA study area encompassed that area plus a 1 kilometer buffer. Additional land cover for the buffer area was generated from United States Department of Agriculture (USDA) National Agricultural Imagery Program (NAIP) four band (red, green, blue, and near infrared) aerial photography at 1 m spatial resolution from July, 2011 and LiDAR from 2010. Six land cover classes were mapped: water, impervious surfaces, soil and barren land, trees, grass-herbaceous non-woody vegetation, and agriculture. An accuracy assessment of 600 completely random and 55 stratified random photo interpreted reference points yielded an overall User's fuzzy accuracy of 87 percent. The area mapped is the US Census Bureau's 2010 Urban Statistical Area for New York City plus a 1 km buffer.

Idaho Wetland Conservation Prioritization Plan - 2012Idaho Department of Fish and Game used GIS to prioritize wetlands for acquisition, long-term conservation, and restoration. Three broad criteria were considered: 1) wetland types; 2) wetland functions and values; and 3) wetland threats and impairments. Ecological systems known to be rare, reduced in extent, sensitive to disturbance, difficult to restore, and/or declining in Idaho were included in the wetland type criteria. The extent of these ecological systems (mapped in a 30 m2 pixel raster layer) was estimated using existing maps and vegetation plot data. Habitat function was assessed by analyzing the capacity of wetlands to support wildlife Species of Greatest Conservation Need and special status plants. Recreational values of wetlands were estimated by creating a statewide GIS model of recreational opportunity. Spatial layers mapping the extent of recreation sites were used. Idaho’s landscape-scale wetland assessment tool was used to estimate the relative condition of wetland habitats. A series of filters were used to identify wetlands of high conservation priority. The resulting layer was then reduced to clusters of pixels that were > 80 ac. This threshold was used to target larger wetland blocks whose conservation or restoration would have the largest positive impact on the health of a watershed, ecological connectivity, and local communities. Sixty large wetland complexes meeting the prioritization criteria and passing all filters were identified and included in this dataset.

Vermont Conservation Design is the data and the vision that identifies features at the landscape and natural community scales that are necessary for maintaining an ecologically functional landscape – a landscape that conserves current biological diversity and allows species to move and shift in response to climate and land-use changes. At the landscape scale, users can see patterns in Vermont’s forests, waterways, and the places that connect both into functional networks. At the community scale appear significant natural communities, lakes representing high quality examples of different lake types, and similar important features that are vital to assemblages of plants and animals. Finally, a user can see components that support individual species—the habitats and locations on which rare and uncommon species rely, for example. On the map, community and species scale components are combined. At all scales, Vermont Conservation Design identifies locations of ecological priority. These are divided into "priority" or "highest priority" areas, to allow users to make informed decisions about the locations most suitable for development and those on which to focus conservation efforts. What makes Vermont Conservation Design unique is that instead of looking at one ecological component at a time—wetlands, rare species, large forest blocks, etc.—Vermont Conservation Design takes a holistic approach, identifying how these components work together to create a functional network of habitat that can be used by most Vermont species. In other words, all components are combined at each scale to identify overall priorities.

This dataset depicts wetlands in Vermont. It was created with an automated feature-extraction process that relied on high-resolution LiDAR and multispectral imagery. In particular, a Compound Topographic Index (CTI) layer derived from LiDAR was used to identify landscape features that have suitable topography and flow potential for wetlands. Moderate-scale (10 m) statistical models developed by Patrick Raney of Ducks Unlimited were also used during classification in a data-fusion approach that maximized the value of individual inputs. After initial identification, mapped features were assigned to one of three primary wetlands classes: Emergent, Scrub\Shrub, and Forested. The class assignments were based primarily on vegetation height (as estimated from LiDAR) and spectral characteristics (e.g., features with short vegetation that appeared very bright in leaf-off multispectral imagery were assigned to the Emergent category). The initial map was then generalized to eliminate unnecessary detail using a minimum mapping unit of 0.1 acres. In a final step, the automated output was manually reviewed against multispectral imagery and obvious errors of commission and omission were corrected. More than 57,000 manual corrections were incorporated into the final layer. Overall, the combination of automated feature extraction and manual corrections was biased toward over-prediction, focusing on capture of borderline features whose functional status cannot be definitvely established with remote-sensing data alone (i.e., it is generally easier to discount false wetland features than it is to locate omitted ones). Known areas of overestimation include managed forestlands with extensively-modified drainage patterns and wide river and stream channels. This map is considered current as of 2016, the year of the most-recent multispectral imagery used during manual review.
