This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. 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. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries. Please reference the metadata for contact information.

The National Wetlands Inventory, found in the A-16 National Geospatial Data Asset Portfolio, contains approximate location and type of wetlands and deep water habitats in the United States and its Territories. The U.S. Fish and Wildlife Service is the principal federal agency that provides information to the public on the extent and status of the nation's wetlands. Wetlands provide a multitude of ecological, economic and social benefits. They provide habitat for fish, wildlife and a variety of plants. Wetlands are nurseries for many saltwater and freshwater fishes and shellfish of commercial and recreational importance. Wetlands are also important landscape features because they hold and slowly release flood water and snow melt, recharge groundwater, act as filters to cleanse water of impurities, recycle nutrients, and provide recreation and wildlife viewing opportunities for millions of people.Digital wetlands data are intended for use with base maps and digital aerial photography at a street level scale (1:12,000) or smaller. Due to the scale, the primary intended use is for regional and watershed data display and analysis, rather than specific project data analysis. The map products were neither designed nor intended to represent legal or regulatory products.Questions or comments regarding the interpretation or classification of wetlands or deep water habitats can be addressed by visiting National Wetlands Inventory - Frequently Asked Questions (FAQs). Due to the quantity and complexity of the wetlands data the wetlands only display at a city scale (1:250,000) and greater. Thumbnail source image courtesy of: LivingLandscapeArchitecture

This web mapping service is intended to provide information on Iowa's wetlands. In particular, data recorded in the National Wetland Inventory.

Wetlands are areas where water is present at or near the surface of the soil during at least part of the year. Wetlands provide habitat for many species of plants and animals that are adapted to living in wet habitats. Wetlands form characteristic soils, absorb pollutants and excess nutrients from aquatic systems, help buffer the effects of high flows, and recharge groundwater. Data on the distribution and type of wetland play an important role in land use planning and several federal and state laws require that wetlands be considered during the planning process.The National Wetlands Inventory (NWI) was designed to assist land managers in wetland conservation efforts. The NWI is managed by the US Fish and Wildlife Service.Dataset SummaryPhenomenon Mapped: WetlandsCoordinate System: Web Mercator Auxiliary SphereExtent: 50 United States plus Puerto Rico, the US Virgin Islands, Guam, American Samoa, and the Northern Mariana IslandsVisible Scale: This layer preforms well between scales of 1:1,000,000 to 1:1,000.

A Wetland of International Importance under the Ramsar Convention (RAMSAR) is part of the Protected Natural Areas (ENP) that are designated or managed within an international, Community, national or local framework to achieve specific objectives for the conservation of the natural heritage.A Wetland of International Importance of the Ramsar Convention is a designated area under the Convention on Wetlands of International Importance, particularly as Waterbird Habitats, whose treaty was signed in 1971 on the Caspian Sea (Iran). Its entry into force dates from 1975, the ratification by France of 1986.The inclusion on the World List of Ramsar Areas presupposes that the area meets one or more criteria demonstrating its international importance.Reference Texts: Ramsar Convention (Iran) of 2 February 1971 and Act of Ratification of the Convention. The objectives are to halt the trend of wetlands becoming extirpated, to promote the conservation of wetlands, their flora and fauna, and to promote and promote the wise use of wetlands. The addition of sites to the list is done by the State which submits duly substantiated proposals to the Ramsar Convention Bureau. In practice, the DREALs carry out the technical files under the authority of the prefects. They are then validated by the National Ramsar Committee set up by the Minister for the Environment.

This map serves as the baseline for the green infrastructure apps that visualize areas that are relatively undisturbed by development or agriculture.The habitat cores shown were derived using a model built by the Green Infrastructure Center Inc. and adapted by Esri.The Intact Habitat Near Me app uses this web map as its basis.This web map provides an easily accessible data base of intact core habitat areas across the continental United States, appropriate in scale to support Green Infrastructure Planning at local, regional and national scales, using the best available national data. The results are intended to be supplemented or replaced with more current or higher resolution data when available, while still supporting Green Infrastructure planning initiatives at the regional level.Using a methodology outlined by the Green Infrastructure Center, Inc. Esri staff created a national intact habitat cores database for the lower 48 United States.The methodology identified, using nationally available datasets, intact or minimally disturbed areas at least 100 acres in size and with a minimum width of 200 meters.The identification of intact areas relied upon the 2011 National Land Cover Database. Potential cores areas were selected from land cover categories not containing the word “developed” or those categories associated with agriculture uses (crop, hay and pasture lands). The resulting areas were tested for size and width requirements, and then converted into unique polygons.These polygons were then overlaid with a diverse assortment of physiographic, biologic and hydrographic layers to use in computing a “core quality index”.These layers included:Number of endemic species (Mammals, Fish, Reptiles, Amphibians, Trees) (Jenkins, Clinton N., et. al, (April 21, 2015) US protected lands mismatch biodiversity priorities, PNAS vol.112, no. 16, www.pnas.org/cgi/doi/10.1073/pnas.1418034112)Priority Index areas: Endemic species, small home range size and low protection status.

Following a methodology outlined by the Green Infrastructure Center Inc., Esri staff created a national intact habitat cores database for the lower 48 United States. These data were generated using 2011 National Land Cover Data. Cores were derived from all “natural” land cover classes and excluded all “developed” and “agricultural” classes including crop, hay and pasture lands. The resulting cores were tested for size and width requirements (at least 100 acres in size and greater than 200 meters) and then converted into unique polygons. This process resulted in the generation of over 550,000 intact habitat cores. These polygons were then overlaid with a diverse assortment of physiographic, biologic and hydrographic layers to populate each core with attributes (53 in total) related to the landscape characteristics found within. These data were also compiled to compute a “core quality index”, or score related to the perceived ecological value of each core, to provide users with additional insight related to the importance of each core when compared to all others.

As a result, 9 separate index scores were generated for each core, each placing varying weights on landscape characteristics of regional or local significance. This was done to account for variation across the U.S. and to provide users with additional flexibility in accommodating regional or local environmental priorities.Two general approaches were used in developing the core quality index values. The first, Default Weights, uses core size as the primary determinant of quality, following the guidance of the Green Infrastructure Center’s scoring approach developed for the southeastern US. The second, Bio-Weights, puts more emphasis on characteristics associated with bio-diversity and uniqueness of ecosystem types and de-emphasizes slightly the importance of core size. This alternative was developed to compensate for the very large intact core habitat areas in the west and southwest which also have comparatively low biodiversity values.Scoring values:Default Weights0.4, # Acres0.1, # Thickness0.05, # Topographic Diversity (Standard Deviation)0.1, # Biodiversity Priority Index (Species Richness in GIC original version)0.05, # Percentage Wetland Cover0.03, # Ecological Land Unit – Shannon-Weaver Index (Soil Variety in GIC original version)0.02, # Compactness Ratio (Area relative to the area of a circle with the same perimeter length)0.1, # Stream Density (Linear Feet/Acre)0.05, # Ecological System Redundancy (Rare/Threatened/Endangered Species Abundance (Number of occurrences) in GIC original version) 0.1, # Endemic Species Max (Rare/Threatened/Endangered Species Abundance (Number of unique species in a core) in GIC original version) Bio-Weights0.2, # Acres0.1, # Thickness0.05, # Topographic Diversity (Standard Deviation)0.25, # Biodiversity Priority Index (Species Richness in GIC original version)0.05, # Percentage Wetland Cover0.03, # Ecological Land Unit – Shannon-Weaver Index (Soil Variety in GIC original version)0.02, # Compactness Ratio (Area Relative To The Area Of A Circle With The Same Perimeter Length)0.1, # Stream Density (Linear Feet/Acre)0.1, # Ecological System Redundancy (Rare/Threatened/Endangered Species Abundance (Number of occurrences) in GIC original version) 0.1, # Endemic Species Max (Rare/Threatened/Endangered Species Diversity (Number of unique species in a core) in GIC original version) Scripts for constructing local cores and scoring them using the Green Infrastructure Center’s methodology are available on http://www.esri.com/about-esri/greeninfrastructure

View the remaining intact habitat near you, and other measures of natural and man-made assets that connect us.The habitat cores shown were derived using a model built by the Green Infrastructure Center Inc. and adapted by Esri.This app includes an easily accessible layer of intact core habitat areas across the continental United States, appropriate in scale to support Green Infrastructure Planning at local, regional and national scales, using the best available national data. The results are intended to be supplemented or replaced with more current or higher resolution data when available, while still supporting Green Infrastructure planning initiatives at the regional level.Using a methodology outlined by the Green Infrastructure Center, Inc. Esri staff created a national intact habitat cores database for the lower 48 United States.The methodology identified, using nationally available datasets, intact or minimally disturbed areas at least 100 acres in size and with a minimum width of 200 meters.The identification of intact areas relied upon the 2011 National Land Cover Database. Potential cores areas were selected from land cover categories not containing the word “developed” or those categories associated with agriculture uses (crop, hay and pasture lands). The resulting areas were tested for size and width requirements, and then converted into unique polygons.These polygons were then overlaid with a diverse assortment of physiographic, biologic and hydrographic layers to use in computing a “core quality index”.These layers included:Number of endemic species (Mammals, Fish, Reptiles, Amphibians, Trees) (Jenkins, Clinton N., et. al, (April 21, 2015) US protected lands mismatch biodiversity priorities, PNAS vol.112, no. 16, www.pnas.org/cgi/doi/10.1073/pnas.1418034112)Priority Index areas: Endemic species, small home range size and low protection status.

This service is published by UConn CLEAR and is made available on CTECO. The thematic raster has multiple classes that represent different land covers. This dataset is part of the Changing Landscape series which includes 7 dates of land cover spanning 30 years, from 1985 to 2015, including change and statistics.

This webmap displays sea level rise inundation scenarios for the state of North Carolina. The map also includes C-CAP high resolution land cover data for water and impervious surfaces. This map was developed to support the North Carolina National Estuarine Research Reserve (NERR). Boundaries for National Estuarine Research Reserve locations are displayed on this map as well. For sea level rise scenarios, the map displays three levels of inundation relative to Mean Higher High Water (MHHW). The 0.0 feet of inundation presents as baseline condition for high tide water levels. A layer for 2.0 feet of sea level rise inundation approximates a spring tide (or extreme high tide) water level for the Intermediate scenario at year 2060. A layer for 4.5 feet of sea level rise inundation approximates a spring tide (or extreme high tide) water level for the Intermediate scenario at year 2100. Sea level rise inundation data displayed in these layers are from NOAA 's Office for Coastal Management's Sea Level Rise Viewer. Visit the Digital Coast tool page for the Sea Level Rise Viewer to find more information, access the tool or download data.Coastal Change Analysis Program (C-CAP) High Resolution land cover image services display impervious surfaces associated with buildings, roads, pavement and railways as well as open water coverage. Visit the C-CAP High-Resolution Land Cover homepage to learn more about the data and access download options.

This tile service displays NOAA OCM's Sea Level Rise Viewer data for 0.0 feet of inundation above Mean Higher High Water (MHHW) for the North Carolina coast, which represents a baseline high tide condition.
