Living Shorelines are a large-scale restoration effort designed to mitigate shoreline erosion by attenuating wave energy. This often includes a combination of natural and manmade offshore structures called breakwaters that encourage sediment retention and promote the re-establishment of marine ecosystems. These breakwaters can significantly influence the characteristics of marine sediments, with the potential to subsequently modify marine infaunal communities that reside in them. Infauna play an important role in sediment biogeochemistry, and form critical links in food chains supporting higher trophic levels including fisheries species. Therefore, restoration activities may have cascading effects on the surrounding ecosystem through their effects on infauna, but it is unclear how infauna communities respond to living shoreline restoration. To investigate these effects, infauna and sediment cores were taken in proximity to breakwaters at living shorelines and adjacent control sites at multiple large-scale living shorelines in Alabama in 2022 and 2024. The wave environment was also characterized at each site. Sites were examined across a gradient of shoreline responses to restoration, ranging from ongoing high rates of shoreline erosion to shoreline accretion. By examining patterns in infaunal communities across a range of sites with different breakwater types, our findings will help quantify the success of these large scale restoration projects in delivering additional ecosystem benefits such as enhanced food supply for fisheries species. This research provides a critical ecological metric for decision-makers, directly linking different restoration designs to the provision of ecosystem services and informing future efforts to maximize the resilience and sustainability of the Gulf coast.
