The extent and rate of coastal wetland loss in the northern Gulf of Mexico is substantially greater than anywhere else in the conterminous U.S. Marsh terracing is a coastal restoration technique commonly implemented in Louisiana and Texas to mitigate wetland loss. Marsh terraces are segmented ridges of bare soil constructed from subtidal sediments in shallow, open water areas of coastal wetlands. Following construction, terraces are often planted with marsh vegetation to prevent their erosion. Despite widespread use of marsh terraces, past monitoring and research efforts have provided limited understanding of their efficacy and persistence. Our proposed project will simultaneously address six aspects of terrace performance to assess the benefits of marsh terraces and determine how they are influenced by elements of their design and application.Collectively, spatial and temporal collection of these data will generate results to effectively inform the coastal restoration community of terrace efficacy, adaptively informing the allocation of fiscal resources toward the most effective restoration projects and design characteristics.
