This data set consists of digital data describing wetlands and uplands habitats for the Mississippi Coastal Improvements Program (MsCIP) area, consisting of Cat, Ship, Horn and Petit Bois Islands for the year 2021. Wetlands were classified using the Federal Geographic Data Committee (2013) wetlands classification scheme to the level of freshwater and tidal salinity modifiers. For this dataset, upland dunes were delineated as areas at or above 1.524 meters (5 feet) as determined in the Lidar data without modification for this classification. With this elevation criteria some delineated upland dune features may be high beach berms. Neighboring habitats bordering these upland dune areas are included in the National Wetlands Inventory (NWI) classification system. Examples include, irregularly flooded, E2EM1P which is estuarine, emergent vegetation above tidal level, whereas E2EM1N is tidally influenced and has direct connection to tidal flow.

This data set contains sensitive biological resource data for wading birds, shorebirds, waterfowl, raptors, diving birds, pelagic seabirds, passerine birds, and gulls and terns in coastal Louisiana and the Lower Mississippi River. Vector polygons represent locations of wading birds, shorebirds, waterfowl, raptors, diving birds, pelagic birds, passerine birds, and gulls and terns that may be particularly vulnerable because of nesting, migratory staging, and wintering activities. Vector points represent locations of nesting and roosting sites for shorebirds, wading birds, diving birds, seabirds, gulls, and terns. Species specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer. This data set comprises a portion of the ESI data for Louisiana. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.

This dataset contains shorebird survey data conducted before (pre) and after (post) barrier island restoration of Cat and Ship Island, Mississippi. The Mississippi barrier islands provide critical habitat for migratory and resident shorebirds, including many federally threatened and endangered (T&E) species. Long-term monitoring of shorebirds before and after restoration is essential to understand how the shorebirds respond to barrier island habitat change. These data will be used to inform the Mississippi Coastal Improvements Program (MsCIP) Monitoring and Adaptive Management Plan (MAMP) objectives, including modeling suitable shorebird foraging habitat and suitable habitat acreage for threatened and endangered (T&E) shorebird species.

Seagrass or submerged aquatic vegetation (SAV) is a valuable and abundant resource found within Gulf Islands National Seashore. It provides habitat for many fish and invertebrates. Seagrass grows in shallow waters and, therefore, is prone to damage and erosion from boats, propellers, fishing equipment, and wakes. We have employed an object-based image analysis technique using Trimble eCognition software to quantify the seagrass and provide a baseline for future studies.

This data release includes data from 1996-2005 for the Louisiana Barrier Island Comprehensive Monitoring Program. Specifically, this data release includes general habitat maps for West Chenier Plain, Early Lafourche Delta, Late Lafourche Delta, Modern Delta, Chandeleur Islands Regions. Please consult the accompanying readME.txt file for information and recommendations on the contents of this dataset (that is, dataset and recommended symbology).

This data set contains sensitive biological resource data for submerged aquatic vegetation (SAV) and rare plants in Maryland. Vector polygons in this data set represent the SAV and rare plant locations. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Maryland. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.

This data set contains sensitive biological resource data for Sargassum in Louisiana. Vector polygons in this data set represent areas of known Sargassum aggregation. Species specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.

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), which represents a biological definition of wetlands and deepwater habitats. There is no attempt to define the limits of proprietary jurisdiction of any Federal, State, or local government, or to establish the geographical scope of the regulatory programs of government agencies. Some wetland habitats may be under represented or excluded in certain areas 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 and also some deepwater reef communities (coral or tuberficid worm reefs). These habitats, because of their depth and water clarity, go undetected by most 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 boundaries, specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.
