The Mobile Bay National Estuary Program is one of 28 National Estuary Programs established by the United States Environmental Protection Agency, focused on safeguarding and restoring the water quality and ecological health of nationally significant estuaries (Ref 2). One of the four main areas of work of the project (Ref 2) is focused on Ecosystem Restoration and Protection (ERP), aiming at restoring and protecting ecosystem function and services (Ref 4). One of the projects implemented in 2023-2024 in the ERP category is the Deer River Coastal Marsh Stabilization and Restoration project, aiming at restoring and protecting the saltwater marshes of the area (Ref 8). The issues faced in the Deer River Shoreline are shoreline recession, marsh deterioration, and loss of natural function from erosion, apparently caused by heavy storms, tidal impacts, and wakes from cargo ships entering or exiting the Theodore Ship Channel (Ref 8). Indeed, the saltwater marshes of this area have started to erode at a rapid rate, up to 12 feet per year (Ref 7). The project aims to enhance the natural function of ecosystem services to improve the area's resilience. It will restore the eroded marsh by creating offshore structures to protect the shoreline and attenuate the waves. The project also aims to restore the water quality of the Deer River by dredging it out, thus improving the water flow. The material dredged out will be used to nourish the marsh (Ref 9).

Implementation activities
Climate-focused activities
Climate change adaptation:
- Restore mangroves, marshes, reefs and wetlands to dissipate the effects of storms and floodwaters
- Restore sediment supply to coastal zone
- Protect and restore coastal ecosystems, to address loss of land and livelihoods, due to rising sea levels
- Restore rivers and other fresh water bodies to reduce flood or drought risk
