Coastwide Reference Monitoring System– Wetlands (CRMS-Wetlands) The CWPPRA monitoring program, CRMS-Wetlands, evaluates the effectiveness of each constructed restoration project in creating, restoring, protecting, and enhancing the coastal wetlands in Louisiana. The CRMS-Wetlands helps the State meet these objectives by providing a network or “pool” of reference sites that can be used to evaluate the effectiveness of individual projects. CRMS-Wetlands will also ensure that the state’s comprehensive restoration plan for coastal restoration is indeed restoring hydrologic basins and entire coastal ecosystems—not just the areas directly affected by individual projects. CRMS-Wetlands will also provide data to fill information gaps and help refine hydrodynamic and ecological models developed as part of the state’s overall coastal restoration program.

As a result of damage to the Breton Sound estuary, the LDNR was proactive in its management of the Caernarvon Freshwater Diversion. The operational plan of the diversion was changed to increase the footprint of the diversion to assist in marsh recovery. In addition to the establishment of the CPRA and the Coastal Protection and Restoration Fund, it is anticipated that there will be additional legislative enactments and policy revisions based upon the continuing assessment of the hurricanes’ impact on coastal Louisiana.
SYNOPSIS The LDNR, its federal partners, and the State Wetlands Authority have implemented projects throughout coastal Louisiana that have been successful at restoring, protecting, and enhancing coastal wetlands. These projects are reducing coastal erosion, improving habitat conditions for coastal fisheries and wildlife species, and building new wetlands. This report provides information about all coastal restoration projects that either have been completed or are in the planning stages in the four Coast 2050 regions to date. It includes a compilation of information from all federal and state agencies involved in coastal restoration in Louisiana.

25 of the tidal hydrology of the Barataria Basin. This project would preserve 147 acres of barrier island habitat over the next 50 years. 2. Caminada Headland Restoration - The Caminada-Moreau Headland protects the highest concentration of near-gulf oil and gas infrastructure in the coastal area. This reach of the Barataria shoreline also supports the only land-based access to the barrier shoreline in the Deltaic Plain. This project would preserve 640 acres of dune and berm over the next 50 years and 1,780 acres of saline marsh.
The Shell Island component of the BBBS Restoration should be constructed at the earliest possible date and include beach restoration by use of containment to rebuild a vital link in the Louisiana barrier shoreline system. The overall goal is to prevent the intrusion of the Gulf of Mexico into the interior bays and marshes, which threatens fisheries and the regional ecology. The project would also help restore natural sand transport along this reach of the coast supporting the adjacent regional shorelines and various shoreline habitats. Numerous infrastructure elements such as highways, levees, ports, and oil and gas facilities located along the rim of the inland bays would incidentally benefit from this ecologic restoration. The Caminada Headland component of the BBBS Restoration should be constructed at the earliest possible date and should include ecosystem restoration of the dune and berm as well as marsh creation. The overall goal of this feature is to maintain this headland reach, which would sustain significant and unique coastal habitats, help preserve endangered and threatened species, continue to transport sand to Grand Isle, and protect Port Fourchon and the only hurricane evacuation route available to the region.

The Caernarvon Freshwater Diversion project, completed in 42 1991, will preserve 16,000 acres of wetlands in the Breton Sound hydrologic basin. Operation of the Caernarvon diversion is anticipated to help rehabilitate marshes lost and damaged by Hurricane Katrina in the upper Breton Sound Basin within Region 2.
Other In Region 2, the Fifi Island Restoration Project, which received funding from the CIAP of 2001, was constructed in 2003. An additional project, Fisheries Habitat Restoration on West Grand Terre Island at Fort Livingston, was also constructed in 2003 and received funding through a NOAA Fisheries grant.

CONCLUSIONS
Since 1989, the LDNR and its ability to design and implement effective partners have been engaged in an effort to coastal restoration projects. Also, the restore, preserve, and enhance Louisiana’s America’s WETLAND campaign will coastal wetlands, which are disappearing at educate the nation and solicit national a current rate of 24 square miles per year. At support for saving Louisiana’s vanishing this rate, an area the size of a football field is coast. Furthermore, technological advances lost every 38 minutes. To date, 676 have enabled the public and scientific restoration projects have been authorized professionals to acquire information and throughout the coastal zone to ameliorate the data on all restoration projects through the state’s wetland loss. As of November 2006, OCRM website. These developments, and the coastal restoration program has the continued dedication of scientists, constructed 77 Breaux Act projects, 44 state engineers, landowners, and the public will projects, 35 federal projects, 397 vegetation help to protect and restore Louisiana’s coast. projects, and 45 PCWRP projects. Despite Knowledge is a powerful tool in the these efforts, land loss remains a significant conservation of natural resources, not only problem in Louisiana. for wetland scientists and project engineers, Restoration project types range from but also for concerned citizens. By large freshwater diversion projects, which remaining aware and informed of coastal divert a portion of a river’s flow, sediment, problems and restoration efforts, individuals and nutrients into entire basins, to small can help preserve Louisiana’s wetlands. vegetation projects, which involve planting Show your support by promoting salt- and flood-tolerant marsh plants to wetland restoration efforts, working with stabilize eroding soils. non-governmental coastal organizations, Among those projects already attending local meetings, and conserving constructed, many have proven to be wetland resources by following fishing and successful. Examples include beneficial use hunting regulations. Help by participating of dredged material and marsh creation in beach clean-ups, environmental education projects, which have created vegetated programs, and in LDNR’s Christmas tree marsh habitat in areas that previously program either by donating your tree after contained deteriorated wetlands or open the holiday season or by volunteering your water. Sediment diversion projects have time to repair and create Christmas tree also been successful in creating marsh in the fences. Through concern and participation, form of crevasse-splays in areas that were citizens can play a role in the success of once shallow open water. Data collected wetland restoration programs and can from these projects are not only used to personally contribute toward the goal of evaluate the effectiveness of individual saving a national treasure. restoration projects, but also to guide the Please visit our website at planning and design of future projects. http://dnr.louisiana.gov/crm for more The LDNR and its partners have information regarding LDNR coastal worked tirelessly to determine the most restoration projects.
