Management and Restoration
Management and Restoration
USGS WARC conducts research in areas experiencing restoration, including coastal Louisiana and the Florida Everglades. This work focuses on providing our partners the information needed to ensure restoration efforts are effective.

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.
Morphology Modeling in Support of the Louisiana Coastal Master Plan
In support of Louisiana’s 2012 Coastal Master Plan, USGS WARC scientists have developed a spatially explicit wetland morphology model and coupled it with other predictive models to help predict the effects of protection and restoration projects.
Geographic Information and Technical Support
USGS WARC first implemented geographic information systems (GIS) in 1980 to assist in monitoring the nature and extent of wetland habitat changes. Today, geographers and support staff create, maintain, and use geospatial data to analyze restoration efforts in Louisiana.
Louisiana Coastal Area (LCA) Ecosystem Restoration Program – Adaptive Management and Monitoring Planning and Implementation Support
Adaptive management (AM) is an iterative science-based process that accepts uncertainties in ecological systems and uses best available science and technology such as research, modeling, experimentation, monitoring and evaluation to address uncertainties.
WaterSMART: Improving Tools for Assessing and Forecasting Ecological Responses to Hydrologic Alteration
WaterSMART (Sustain and Manage America’s Resources for Tomorrow) is a program of the Department of the Interior that focuses on improving water conservation and helping water-resource managers make sound decisions about water use.
Evaluating Structural and Surface Elevation Recovery of Restored Mangroves
Hydrologic restoration is one of several approaches to rehabilitate mangroves on a large-scale. USGS evaluates how solely restoring tidal hydrologic flows affect the recovery of mangroves in Florida.
Ecology of Greenhouse Gas Emissions from Coastal Wetlands
Wetlands have the potential to absorb large amounts of carbon dioxide via photosynthesis, and flooded soils have low oxygen levels which decrease rates of decomposition to promote the retention of soil carbon. However, the type of greenhouse gases emitted from wetlands varies by wetland type and soil condition. A suite of approaches are being used to assess fluxes of greenhouses gases, like...
Stress Physiology, Scaling, and Water Use of Forested Wetland Trees and Stands
USGS investigates the eco-physiological responses of coastal forested wetland vegetation to envrionmental stressors, and what role vegetation may have in affecting local hydrological cycling as a result of these stressors.
Modeling Tidal Freshwater Forested Wetlands (TFFW) Habitat Changes for Land Management
As tidal freshwater forested wetlands - TFFWs - are influenced by salinty due to salt water intrusion, they may experience changes in plant community composition, growth, and productivity. Models are needed to predict vegetation community change or dieback, as well as changes in carbon sequestration and storage due to changing climate, drought, changes in freshwater discharge, elevated carbon...
Predicting the Long-Term Impact of Hurricane Sandy on Spatial Patterns of Wetland Morphology in Salt Marshes of Jamaica Bay, New York
USGS scientists are working with collaborators to understand how Hurricane Sandy impacted wetlands in Jamaica Bay, New York.
Ecology of Tidal Freshwater Forested Wetlands of the Southeastern United States
Tidal freshwater forested wetlands - TFFWs - can be found in the upper intertidal areas of many estuaries and act as a transition between coastal marshes and bottomland hardwood wetlands. However, it is because of their location that makes them vulnerable to sea-level rise, and they are constantly transitioning to different wetland types. USGS addresses how various processes are affected in TFFWs...
Restoration of Climate Change-Induced Retreat of Tidally Influenced Freshwater Forested Wetlands
Wetlands in river deltas - like the Mississippi River Delta Plain - may be more vulnerable to sea-level rise. Historically, coastal wetlands responded to these changes by increasing surface elevation or migrating up-slope. USGS conducts research to identify the biogeochemical influences on sediment addition in coastal wetland areas.
