Biloxi Marsh Oyster Reef Restoration Project
Louisiana recently proposed 5 projects to be funded by the initial round of funding from the RESTORE Act. The Biloxi Marsh Oyster Reef Restoration project, also known as the Biloxi Marsh Living Shoreline project, will construct an oyster barrier reef along the southern and eastern shores of the Biloxi Marsh. This reef will provide a natural protective barrier to reduce the damaging effects of storm surges and provide wave attenuation. Here’s what we wrote to the Louisiana Coastal Protection and Restoration Authority, in support of the Biloxi Marsh Oyster Reef Restoration project:
Dear Coastal Protection and Restoration Authority members,
The undersigned groups appreciate this opportunity to share our collective supporting comments on the Biloxi Marsh Oyster Reef Project, submitted by the State of Louisiana for RESTORE Council consideration for the first Funded Priorities List of the RESTORE Pot 2 Council-selected projects.
We represent a coalition of conservation interests that have worked for decades to restore a healthy Gulf of Mexico ecosystem – starting with prompt restoration of the Mississippi River Delta – reconnecting the Mississippi River to its delta to protect communities, environment, and economies. Our groups continue to recommend urgent action on projects that will reduce land loss and restore wetlands in the Mississippi River Delta through comprehensive restoration actions that have the potential to provide multiple benefits and services over the long term to the entire Gulf of Mexico.
Most of the necessary restoration actions to be undertaken in Louisiana are already fully authorized under the Water Resources Development Act (WRDA) of 2007, were unanimously approved by the Louisiana legislature in the 2012 Coastal Master Plan, enjoy broad public support, and have been vetted by scientists and lawmakers for many years. In the case of the Biloxi Marsh Oyster Reef Project, it has a completed Programmatic EIS and a signed Chief’s Report from the Corps of Engineers.
The Biloxi Marsh platform is relatively stable and enjoys a fairly low rate of subsidence; however, erosion on the marsh edge by wave action has resulted in significant loss of this wetlands habitat over time. Construction of an oyster barrier reef along the southern and eastern shores of the Biloxi Marsh will provide a natural protective barrier to reduce the damaging effects of storm surges and provide wave attenuation. In addition to providing protection against waves, oyster reefs also provide a myriad of ecosystem services including water quality enhancement and benefits to fish populations in both Breton Sound and Mississippi Sound.
Reestablishment of vertical oyster reefs in Biloxi Marsh, in conjunction with the reintroduction of small amounts of river water (River Reintroduction into Maurepas Swamp, Central Wetlands diversions), will help slow marsh deterioration. Additionally, once established, unlike rock and other materials, these reefs are naturally self-maintaining.
Our groups support the development of the Biloxi Marsh Oyster Reef Project—and the concept of living shorelines in general—and commend the selection of this important “line of defense” by the Coastal Protection and Restoration Authority. We look forward to the construction of this project within the next few years as funding becomes available.
