Researchers are investigating beach compaction, the incubation environment for turtle nests, and shorebird nest abundance at beaches throughout the southeastern United States to better understand the impacts of beach compaction to nesting turtles and foraging seabirds.

The Biscayne Bay and Southeastern Everglades Ecosystem Restoration (BBSEER) project will use Bayesian networks developed within the Everglades Vulnerability Analysis framework but with an expanded set of predicted vegetation types to build a spatially explicit model predicting annual probability of vegetation types in response to hydrologic and other landscape factors.

USGS researchers will examine how hydrology and landscape vegetation changes impact Cape Sable Seaside Sparrow survival and population growth.

USGS will collaborate with the Miccosukee and Seminole Tribes to co-design a dashboard mock-up for a real-time web application that monitors tree island health in the Everglades.

USGS will compare the EverForecast hydrologic forecast, the South Florida Water Management District's Position Analysis, and observed water level recordings from gages located across the Everglades landscape to examine which forecast performs better during the wet and dry seasons; wet, dry, or average years; or in different areas of the Everglades.

The USGS Utah Water Science Center and the State of Utah collaborated with WARC's Advanced Applications Team to build a data driven, interactive web application to provide groundwater conditions for Utah.

The Joint Ecosystem Modeling team will be running a suite of ecological models to evaluate scenarios and provide insight into how alternative restorations plans compare, indicate whether alternatives could lead to unintended consequences, and determine effects of alternatives that could conflict with other goals.

In the summer of 2021, instrumented platforms were deployed at Seven Mile Island Living Laboratory, New Jersey to conduct time series measurements of tidal velocity, turbidity, surface elevation, sediment concentration, and suspended sediment characteristics. The collected data will be used to provide decision support to the U.S. Army Corps of Engineers as they plan dredging activities in the Gulf...

WARC researchers partnered with Gulf Sturgeon decision makers and biologists to develop a Bayesian network model that uses habitat characteristics to predict the quantity of juvenile winter foraging habitat under alternative river discharge and timing of juvenile arrival scenarios.

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...

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.

Joint Ecosystem Modeling (JEM) provides ecological models tailored to address specific management issues, for example, the Western Everglades Restoration Project.
