<p><span style='background-color:white; color:rgb(51,51,51); font-size:medium;'><span style='text-align:left;'>This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Trust Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats may be excluded 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.</span></span></p><p><span style='font-size:medium;'>The&nbsp;</span><a style='color:rgb(33, 117, 155);' target='_blank' href='https://www.fws.gov/' rel='nofollow ugc noopener noreferrer'><span style='color:#330000; font-size:medium;'>U.S. Fish and Wildlife Service</span></a><span style='font-size:medium;'>&nbsp;(Service) is the principal Federal agency that provides information to the public on the extent and status of the Nation's wetlands.&nbsp; The Service's strategic plan for our vast national wetland data holdings is focused on the development, updating, and dissemination of wetlands data and information to Service resource managers and the public.</span></p><p><span style='font-size:medium;'>For more information visit:&nbsp; </span><a target='_blank' href='https://www.fws.gov/program/national-wetlands-inventory' rel='nofollow ugc noopener noreferrer'>National Wetlands Inventory | U.S. Fish &amp; Wildlife Service</a></p><p><strong>View</strong> Wetlands Data on the Wetlands Mapper at:&nbsp;<a target='_blank' href='https://www.fws.gov/program/national-wetlands-inventory/wetlands-mapper' rel='nofollow ugc noopener noreferrer'>Wetlands Mapper | U.S. Fish &amp; Wildlife Service</a></p><p>Wetlands <strong>Web Services</strong>&nbsp;are available at:&nbsp;<a target='_blank' href='https://www.fws.gov/program/national-wetlands-inventory/web-mapping-services' rel='nofollow ugc noopener noreferrer'>Wetland Web Mapping Services | U.S. Fish &amp; Wildlife Service</a></p><p>Wetlands Data available as a&nbsp;<strong>KML</strong>&nbsp;at:&nbsp;<a target='_blank' href='https://www.fws.gov/program/national-wetlands-inventory/google-earth' rel='nofollow ugc noopener noreferrer'>View Wetlands Data with a KML file | U.S. Fish &amp; Wildlife Service</a></p><p>Wetlands Data <strong>Downloads</strong>&nbsp;available&nbsp;at:&nbsp;<a target='_blank' href='https://www.fws.gov/program/national-wetlands-inventory/data-download' rel='nofollow ugc noopener noreferrer'>Download Seamless Wetlands Data | U.S. Fish &amp; Wildlife Service</a></p><p>Wetland Data <strong>Standards</strong>&nbsp;available&nbsp;at:&nbsp;<a target='_blank' href='https://www.fws.gov/program/national-wetlands-inventory/data-standards' rel='nofollow ugc noopener noreferrer'>Federal Data Standards for Wetlands | U.S. Fish &amp; Wildlife Service</a></p>
