Gulf Coast Wetland Shoreline Change

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...

Identification of Hydrologic Controls on Coastal Spartina patens Marshes and Optimal Hydrological Conditions for Sustainable Mottled Duck Habitat

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.

Coastwide Reference Monitoring System (CRMS)

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...

Relation between Plant Community Structure and Function and the Effectiveness of Wetland Restoration Efforts

High rates of wetland loss continue to occur along the northern Gulf of Mexico coast, and this remains an issue of concern to resource managers.

Gulf of Mexico Land Loss Change Assessment: A Cooperative Study with the Bureau of Ocean and Energy Management

Eighty-five percent of the coastal wetland loss in the contiguous United States occurs in the Gulf of Mexico. Documenting and understanding the occurrence of this wetland loss will provide for effective planning, mitigation, and restoration activities.

Long-term Trends in Swamp Tree Growth across Drought and Salinity Gradients along the Northern Gulf Coast

This study will examine the potential effects of climate-change-induced sea level rise, drought and water extraction by examining tree growth patterns across the Gulf Coast, specifically targeting long-term research plots available in the North American Baldcypress Swamp Network (NABCSN) and the Suwannee River.

Incorporating Future Change into Current Conservation Planning: Evaluating Wetland Migration along the Gulf of Mexico under Alternative Sea-Level Rise and Urbanization Scenarios

More than half of contiguous U.S. coastal wetlands are located along the Gulf of Mexico coast. These highly-productive wetlands support many ecosystem goods and services and fish and wildlife habitat. Historically, coastal wetlands have adapted to sea-level changes via lateral and vertical movement on the landscape. As sea levels rise in the future, coastal wetlands will adapt and migrate landward...

Ecosystem Development After Wetland Restoration and Creation

Wetland restoration and creation efforts are increasingly proposed as means to compensate for wetland losses. To address the need for evaluating the development of ecosystem structure and function in restored and created wetlands, USGS compared created tidal wetlands sites to natural mangrove wetlands in Tampa Bay, Florida.

Factors Controlling Resilience and Resistance of Coastal Salt Marshes to Sudden Marsh Dieback

Sudden Marsh Dieback - SMD - has been documented for the past two decades throughout coastal areas of the United States. With these large-scale diebacks comes the loss of ecosystem functions and services. USGS scientsts use field work and greenhouse studies to investigate the factors that control the resilience and resistance of coastal salt marshes to SMD.

Integrated Modeling of Coastal Processes and Linkages to Management Applications

Coastal wetlands provide valuable ecosystem services such as wave attenuation, surge reduction, carbon sequestration, wastewater treatment, and critical habitats for endangered fish and wildlife species. However, wetland loss threatens the capacity of coastal wetlands to provide these ecosystem services.

Plant Community Dynamics in a Mangrove-to-Marsh Transition Zone

Mangroves will compete with salt marsh plants in transitional areas, and recent studies have documented the expansion of mangroves into marsh habitats. To better understand the plant community dynamics in this transition zone, USGS scientists are tracking vegeation changes over time in south Florida.
