Estuarine Shoreline Stabilization

Research and Education

Project Summary

This research examines the effects of different estuarine shoreline stabilization methods on the ecosystem services provided by marsh habitat in North Carolina. Some stabilization structures can negatively impact physical and biological components in the estuarine ecosystem. For example, while bulkheads reduce erosion of the land in front of which they are built, in the long term they can result in increased scouring and contribute to erosion of adjacent land. Additionally, critical marsh habitat is often minimal or absent in front of bulkheads. This loss or degradation of habitat means that less marine life, including valuable species like blue crab and flounder, may be supported. Alternative estuarine shoreline stabilization methods will also provide land protection, but with fewer negative consequences to overall ecosystem health.


The goal of this study is to better define the trade-offs between land protection and the loss of ecosystem services related to estuarine shoreline stabilization. To achieve this goal, scientists from several agencies and institutions have partnered to address different aspects of this research project. The project includes three key components:

Measure physical and biological effects of stabilization methods Construct a demonstration site incorporating lessons learned Develop educational material about estuarine shoreline stabilization

 

 

 

 

 

 

 

 

This project is being conducted by an expert team of federal, state and university scientists. Additionally, an Advisory Panel has been formed to guide research development and to help communicate the results to the broader community of regulatory partners, stakeholders and the public.
