Barrier Island Habitat Mapping for the Louisiana Outer Coast Project
The USGS is collaborating with the Louisiana Coastal Protection and Restoration Authority (CPRA) to develop post-restoration barrier island habitat maps for three of the four components associated with the Louisiana Outer Coast Restoration Project
Understanding Ecosystem Response and Infrastructure Vulnerability to Sea-Level Rise for Gulf Islands National Seashore
USGS researchers will will survey elevation and vegetation in wetlands and vegetated dunes on Horn, Petite Bois, and Ship Islands; Correct the best available lidar-based digital elevation model; estimate inundation for the Gulf Islands National Seashore under various water levels and relative sea-level rise scenarios; and quantify and predict potential marsh migration for the Gulf Islands National...
Geospatial Analysis and Data Collection along the U.S. – Mexico Border
USGS researchers will collect geospatial data that will help decision makers monitor and mitigate the direct and indirect impacts of border barrier construction on threatened and endangered species.
Quantifying Changes in Wetland Area and Habitat Types in the Deepwater Horizon Louisiana Restoration Area 1985-Present with Remote Sensing
USGS researchers will quantify wetland change and wetland vegetation community type change through the analyses of aerial vegetation survey data and investigate potential relationships between Normalized Difference Vegetation Index (NDVI) and marsh elevation change.
Barriers and Opportunities for Landward Migration of Coastal Wetlands along Texas' Upper and Middle Coast
Researchers at WARC will use data and models to produce probabilistic maps of current and future wetland inundation, coastal wetland extent, and coastal and wetland trangression.
Monitoring Impacts of U.S.-Mexico Border Barrier and Lighting on Migratory Birds
Researchers will use a multi-scale approach to determine how barrier construction and lighting may impact migratory birds in the Lower Rio Grande Valley.
Seasonal Surveys of Shorebird and Coastal Waterbird Utilization of Dredged Material Islands in the Baptiste Collette Bayou, U.S. Army Corps of Engineers (USACE) New Orleans District, Louisiana
To assess use of dredge material areas, avian ecologists from USGS WARC are conducting bird surveys across the annual life cycle.
Climate Change Science at WARC
USGS science plays an essential role in helping natural resource managers, communities, and policy makers prepare and mitigate for changing environmental conditions.
A Multiscale Approach to Understanding Migratory Landbird Habitat Use of Functional Stopover Habitat Types and Management Efforts
USGS scientists are using a spatially-explicit Bayesian network model to predict the difference between energetic value and energetic demand for stopover habitats for migrating landbirds.
Adapting to Climate Change: Trends and Severe Storm Responses by Migratory Landbirds and Their Habitats
USGS scientists will be analyzing weather surveillance radar observations of birds departing stopover habitats to measure responses to climate change.
Impacts of coastal and watershed changes on upper estuaries: causes and implications of wetland ecosystem transitions along the US Atlantic and Gulf Coasts
Estuaries and their surrounding wetlands are coastal transition zones where freshwater rivers meet tidal seawater. As sea levels rise, tidal forces move saltier water farther upstream, extending into freshwater wetland areas. Human changes to the surrounding landscape may amplify the effects of this tidal extension, impacting the resiliency and function of the upper estuarine wetlands. One visible...
Geospatially Enabled, Web-based Habitat Reporting Tool to Support Monitoring and Assessment along the Louisiana Shore
The State of Louisiana's Barrier Island Comprehensive Monitoring (BICM) program has partnered with USGS to developed two habitat classifications schemes for monitoring barrier island habitats and habitats in beach-dune systems along the mainland. These schemes builds upon previous BICM habitat mapping efforts.
