Coastwide Reference Monitoring System– Wetlands (CRMS-Wetlands) The CWPPRA monitoring program evaluates the effectiveness of each constructed restoration project, and scientifically evaluates how well the restoration projects create, restore, protect, and enhance coastal wetlands in Louisiana. The CRMS-Wetlands helps the state meet both of 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

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 Figure 3. Paths of Hurricanes Katrina and Rita. agencies involved in coastal restoration in Louisiana. Scientists with the USGS estimate that Katrina caused as much as 30 square miles of marsh in Breton Sound to be transformed into open water. An additional 47 square miles of marsh was lost throughout the Pontchartrain, Pearl River, Barataria, and Terrebonne basins. The active Mississippi River Delta incurred approximately 14 square miles of loss. The Chandeleur Islands, one of coastal Louisiana’s barrier island chains that serve as the first line of defense against tropical storms, have been reduced by as much as 50 percent as a result of the hurricanes.

The DNR Public Information Office provides a variety of printed materials, educational videos and cds, fact sheets, website information, and a traveling wetlands exhibit for the public. Other department outreach efforts include participating in conferences, workshops, civic events, and school activities. Much of the agency’s educational outreach is in partnership with the Breaux Act Task Force committees and the America’s WETLAND campaign. As a result of working with several noted authors, writers and reporters, the Public Information Office has contributed to the publishing of hundreds of national articles over the past years. In October 2004, National Geographic Magazine published a widely recognized report on the value and benefits of the state’s wetlands entitled Gone with the Water.

CONCLUSIONS
Since 1989, the LDNR and its coastal restoration projects. Also, the partners have been engaged in an effort to America’s WETLAND campaign will restore, preserve, and enhance Louisiana’s educate the nation and solicit national coastal wetlands, which are disappearing at a support for saving Louisiana’s vanishing current rate of 24 square miles per year. At coast. Furthermore, technological advances this rate, an area the size of a football field is have enabled the public and scientific lost every 38 minutes. To date, 635 professionals to acquire information and data restoration projects have been authorized on all restoration projects through the OCRM throughout the coastal zone to ameliorate the website. These developments, and the state’s wetland loss. As of November 2005, continued dedication of scientists, engineers, the coastal restoration program has landowners, and the public will help to constructed 74 Breaux Act projects, 41 state protect and restore Louisiana’s coast. projects, 35 federal projects, 371 vegetation Knowledge is a powerful tool in the projects, and 37 PCWRP projects. Despite conservation of natural resources, not only these efforts, land loss remains a significant for wetland scientists and project engineers, problem in Louisiana. but also for concerned citizens. By Restoration project types range from remaining aware and informed of coastal large freshwater diversion projects, which problems and restoration efforts, individuals divert a portion of a river’s flow, sediment, can help preserve Louisiana’s wetlands. and nutrients into entire basins, to small Show your support by promoting vegetation projects, which involve planting wetland restoration efforts, working with salt- and flood-tolerant marsh plants to non-governmental coastal organizations, stabilize eroding soils. attending local meetings, and conserving Among those projects already wetland resources by following fishing and constructed, many have proven to be hunting regulations. Help by participating in successful. Examples include beneficial use beach clean-ups, environmental education of dredged material and marsh creation programs, and in LDNR’s Christmas tree projects, which have created vegetated marsh program either by donating your tree after the habitat in areas that previously contained holiday season or by volunteering your time deteriorated wetlands or open water. to repair and create Christmas tree fences.
