Restoration

Using ecological and geographical data, WARC researchers and their partners are analyzing avian and benthic sampling on Whiskey Island and Caminda Headland to compare pre- and post-restoration aspects of habitat occupancy, habitat availability, habitat use, and kernal density estimation.

USGS and partners will identify the causes for the lack of predictive power in some models included in the 2023 Louisiana Coastal Master Plan, and suggest ways to improve the models in future Louisiana Coastal Master Plan modeling exercises.

WARC will assess Cape Sable seaside sparrow population response and viability under different management and habitat change scenarios. The USGS EverSparrow model will be run on future scenarios, and differences in the predicted probability of presence and the efficacy of varying conservation strategies will be evaluated.

USGS researchers are conducting ground surveys and collecting aerial imagery to understand avian use of restored habitats at Whiskey Island, Shell Island, Cheniere Ronquille, and Breton Island. They will also develop habitat maps to understand how coastal processes and episodic events influence barrier islands.

With the support of the Mote Marine Laboratory and Aquarium, USGS researchers will develop and optimize a CRISPR biosensor to detect C. galea eDNA in the field. The development of this tool could assist coral restoration managers and stakeholders to more effectively inform decisions on coral outplant site selection, based on coral predator presence.

USGS researchers will define the range of elevation targets supporting optimal plant performance and soil strength by identifying the lower and upper thresholds of marsh conversion, and characterize ecosystem development of restored marshes over time to identify the lifetime and sustainability of restored marsh during sea-level rise. This work addresses priority science needs to improve...

The USGS is collaborating with the Louisiana Coastal Protection and Restoration Authority (CPRA) to develop post-restoration barrier island habitat maps for three of the four components associated with the Louisiana Outer Coast Restoration Project

USGS will monitor hydrologic and marsh conditions at the Turtle Bayou mitigation area. This effort will help provide a long-term water level dataset for Turtle Bayou.

USGS researchers will collect geospatial data that will help decision makers monitor and mitigate the direct and indirect impacts of border barrier construction on threatened and endangered species.

USGS will install and maintain up to six rod surface-elevation table (RSET) and paired accretion monitoring stations at the location of the Maurepas Swamp Alternative-2 Mitigation Project.

USGS will provide support to the Large-scale Marsh Creation – Upper Barataria Component Project by monitoring change in the area of land and water, and recovery of vegetation and elevation over time.

USGS researchers and their partners will develop a coupled hydrodynamic and water quality modeling system; calibrate and validate the models; assess and predict outcomes of a canal backfilling restoration project on key water quality attributes; and run the modeling system under a suite of scenarios reflecting changing environmental conditions.
