Some of the greatest rates of coastal wetland loss in North America occur along the U.S. coast of the Gulf of Mexico. One coastal restoration technique commonly used to mitigate wetland loss in Louisiana and Texas is marsh terracing, whereby ridges of sediment are constructed and planted with vegetation to help protect surrounding areas against erosion from wind and waves. Despite widespread use, past monitoring and research efforts have yielded only limited understanding about the efficacy and persistence of marsh terraces. Through close collaboration with practitioners, this project aims to address this gap and will examine past marsh terracing projects to evaluate their effectiveness as a coastal restoration technique and provide guidance on their use in future restoration efforts.
