Wetlands

The USGS is collaborating with researchers from other agencies, academia, and industry to predict coastal impacts from hurricanes. The results from this study will better inform coastal morphological change models, which will lead to improved hurricane impact projections.

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.

The Gulf Coast Joint Venture (GCJV) was established in 1988 as a result of the North American Waterfowl Management Plan, which espouses the restoration of continental waterfowl populations through conservation partnerships in priority habitat regions. Since that time GCJV partners have expanded their mission and purpose to include the provision of habitat to support other priority bird species...

WARC researchers are working to quantify the impacts of future climate and land use/land cover change on greenhouse gas emissions and reductions.

To ensure successful restoration of coastal wetlands, WARC researchers will measure carbon cycling processes that indicate ecosystem health and sustainability.

Coastal environments are dynamic systems that provide high ecological, economical, recreational, and cultural value. Managing coastal systems requires a comprehensive understanding of the complex interactions between geological and ecological processes, as well as the ability to predict both the near-term and long-term impacts of storms and sea-level rise. The Coastal Resource Evaluation for...

The goal of the Estuarine and MaRsh Geology (EMRG) Research Project is to study how and where short- and long-term marsh and estuarine coastal processes interact, how they influence coastal accretion or erosion, and how they pre-condition a marsh’s resiliency to storms, sea-level change, and human alterations along the northern Gulf of Mexico (Grand Bay and Point aux Chenes, Mississippi and St...

USGS WARC scientists are monitoring both the long- and short-term effects of coastal restoration efforts on ecosystem health in coastal habitats of Louisiana’s Barataria Basin.

USGS researchers will provide technical guidance to inform the development of monitoring plans for the western coast of Louisiana.

Land and seafloor slopes are generally low along the coasts in the Mid-Atlantic and Gulf Coast states, making wetlands and estuaries vulnerable to sea level change, subsidence, and extreme events (e.g., hurricanes and tropical storms). Land-use change and land loss have been mapped extensively and with increasing frequency, but the link between land loss and the processes responsible for landscape...

Mottled ducks rely on the coastal marshes of the Texas Chenier Plain, which are considered among the most critically endangered habitats in the United States. USGS scientists are evaluating what might be contributing to the degradation of high-quality mottled duck habitat to better understand the causes of habitat loss and subsequently mitigate those losses.

CRMS uses a multiple reference approach to biological monitoring and uses aspects of hydrogeomorphic functional assessments and probabilistic sampling that address the limited effectiveness of the traditional paired-reference monitoring approach in Louisiana. This approach includes a suite of sites that encompass the range of ecological conditions for each stratum, with projects placed on a...
