Wetlands
Wetlands
Wetlands offer many significant benefits for fish and wildlife as well as society. They provide habitat for thousands of species of aquatic and terrestrial plants and animals. Wetlands are valuable to humans for flood protection, water quality improvement, shoreline erosion control, natural products, recreation, and aesthetics. WARC researchers provide scientific understanding of how wetlands work and the importance of wetlands to both humans and the plants and animals that rely on healthy wetlands to survive.

Wetland Methane Emissions: Functional-type Modeling and Data-driven Parameterization
To better understand the environmental drivers of methane emissions in tidal saltmarsh, tidal freshwater swamp forest, tidal freshwater marsh, and non-tidal freshwater marsh habitats, researchers are collecting observations of CH4 emissions and porewater concentrations at research sites representative of each of these habitats.
Wetland Carbon Working Group: Improving Methodologies and Estimates of Carbon and Greenhouse Gas Flux in Wetlands
WARC researchers are working to quantify the impacts of future climate and land use/land cover change on greenhouse gas emissions and reductions.
Wetland Carbon Cycling: Monitoring and Forecasting in a Changing World
WARC's wetland carbon cycle science team is working to improve model parameterizations and formulations and reduce forecast uncertainty in ecosystem modeling.
Understanding Impacts of Sea-Level Rise and Land Management on Critical Coastal Marsh Habitat
To ensure successful restoration of coastal wetlands, WARC researchers will measure carbon cycling processes that indicate ecosystem health and sustainability.
Prevalence Rates of Snake Fungal Disease and Its Population-level Impacts in a Snake Assemblage in Southwest Louisiana
WARC researchers used visual encounter surveys to determine prevalence rates of snake fungal disease in south-central Louisiana.
Amphibian Research and Occupancy Modeling in the South-Central Region of the Amphibian Research and Monitoring Initiative (ARMI)
In response to growing public concerns about this loss of biodiversity, the U.S. Congress funded the Amphibian Research and Monitoring Initiative (ARMI), a national program coordinated by the U.S. Geological Survey.
Interaction of Environmental Stressors and Batrachochytrium dendrobatidis (Bd) Pathogen Loads on Survival of Green Frogs (Lithobates clamitans)
The U.S. Geological Survey Amphibian Research Monitoring Initiative (ARMI) is using a combination of swabbing, non-lethal tissue sampling, soil and water sampling, and collection of a variety of other environmental variables to determine the relationships between the prevalence and pathogen load of Bd infection and environmental stressors on green treefrog survival.
Critical Coastal Habitats: Sustainability, Restoration and Forecasting
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.
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...
Applications of Advanced Tracking and Modeling Tools with Burmese Pythons across South Florida's Landscape
Researchers will determine movement rates and habitat-use patterns of pythons across the South Florida landscape by conducting a telemetry study tracking pythons simultaneously in several locations
Habitat Selection of the Burmese Python in the Florida Everglades
Researchers plotted locations of radio-tagged pythons to create a habitat suitability model.
Multispecies Operational Forecasting in the Florida Everglades
A USGS forecasting tool helps Everglades natural resource managers identify management actions that can benefit one or more species while quantifying the potential costs to others.
