"Coastal Wetlands Planning, Protection, and Restoration Act"
The Coastal Wetlands Planning, Protection and Restoration Act, (CWPPRA pronounced kwǐp-rŭh), is federal legislation enacted in 1990 that is designed to identify, prepare, and fund construction of coastal wetlands restoration projects. Since its inception, 210 coastal restoration or protection projects have been authorized, benefiting over 97,401 acres in Louisiana.
Today is World Soils Day, time to talk about soil pollution and wetlands! Soil pollution is often referred to as “invisible” because, although pollution can be detected through testing [LINK TESTING], it is much more difficult to see with the naked eye. Some of the biggest players in soil pollution today are improper waste management, agricultural runoff, and industrial processes. You may not think you are directly impacted by soil pollution, but you are.
Polluted soil in agricultural fields is arguably the most direct impact to humans because the pollutants are taken into the crop, whether it is a plant or animal, and make it into our food stream.  Pollutants in soils are also less hospitable to plant recruits, which is terrible news for coastal Louisiana. Our coastal wetlands provide us with many things that we rely on, and we cannot afford to lose our wetlands to preventable pollution. When soils do not incorporate healthy plant roots, they are much more susceptible to erosion. When moving sediments around, CWPPRA wants to make sure that plants can re-establish effectively, so they want healthy soils. 
Areas with unsustainable levels of pollution are spreading, and non-point source pollution, which includes road and agricultural runoff, is very hard to track and very hard to remediate. Pollutants are not easily scrubbed from soils on a mass scale and so they follow the flow of water. Runoff travels through watersheds just like clean water and makes its way into our coastal wetlands with damaging consequences. Coastal wetlands are resilient ecosystems, but they have limits. We cannot overburden them with harmful, carefree attitudes towards pollution. Our coast deserves to be protected. Our coast deserves to be respected.
Some of you may remember the 1989 film “Field of Dreams,” and perhaps the famous quote “If you build it, he will come.” Meant as motivation to build a baseball diamond in a corn field, the line encourages dreaming big and following your passion. It can also apply directly to environmental protection and restoration. CWPPRA builds wetlands, and ecologically diverse communities come. They may take a long time, but they will come. Creating a resilient environment requires hard work, and the environment will return on investment many times over.
Biodiversity has a massive positive effect on the productivity of a system,  and we in Louisiana have some of the most productive wetland ecosystems in the United States. Coastal fisheries today produce about 40% of the world’s wild-caught seafood, according to the WWF,  and wild-caught fish rely heavily on a healthy ecosystem to produce populations large enough to harvest. Unfortunately, many fish communities are over- exploited and have a lot of bycatch, causing species declines and shifts in the health of the community. It doesn’t have to be this way, though. Sustainable fishing is an achievable goal.
By using our bountiful resources and productive wetlands, we can cultivate thriving ecosystems that don’t need much maintenance at all. A perfect model would require no feed, no destructive fishing methods like trawling or wasteful bycatch, and it would have numerous benefits to wetland health such as better nutrient capture, pollutant filtration, food production, biodiversity, and even improved resilience.  Such a complex problem cannot be solved overnight, but focusing on the health of our fisheries will drive them to be more sustainable, and sustainable fisheries will keep our critical $2.4B seafood industry alive. Our coastal zone is a great asset that provides us with plentiful resources, and we have a responsibility to use those resources, such as the fisheries, in a sustainable manner. Programs like CWPPRA emphasize the benefits of sustainability on a large scale and seek to apply those practices in their restoration projects.
High winds and waves prevent GIWW sediments transported down the Freshwater and Schooner bayous from settling and forming the basis of vegetated marsh. This same wind and wave energy also increases shoreline erosion rates.
This project involved the construction of a series of vegetated terraces to diminish waves in Little Vermilion Bay, helping to increase sediment deposition and reduce the rate of shoreline erosion. A pattern of channels was dredged 100-feet wide and 6-feet deep to beneficially distribute sediment from the GIWW through the Freshwater and Schooner bayous. Dredged sediments were used to construct 23 earthen terraces with a combined length of 23,300 feet. After settling, the average height of the terraces was 3.5 feet above mean sea level.
The bases of the terraces were planted with 20,450 containers of smooth cordgrass (Spartina alterniflora).
The design allows commercial and recreational fisherman to access the project area, and it stimulates fishery production by creating new habitat and increasing shoreline length.
In 1998 alone (prior to the project’s completion) 40 acres of wetland habitat were created.
This project is located in the northwestern corner of Little Vermilion Bay at its intersection with the Gulf Intracoastal Waterway (GIWW) in Vermilion Parish, Louisiana. The project area encompasses 964 acres.
Monitoring is underway and preliminary observations show that the terraces are growing in width, and bay depth between terraces is decreasing indicating marsh expansion in the project area.
When celebrating Thanksgiving tomorrow, be sure to think about all of the ways wetlands provide for you and yours. Whether you enjoy the serene experience of watching a sunset through bald cypress trees, catching redfish in the marsh with your family, or simply love a good shrimp po-boy, Louisiana wetlands provide a huge number of services to millions of people daily.
In addition to protecting our cities from storm surge, wetlands of all kinds host tremendous species diversity, are highly productive, and allow for many types of recreation. Louisiana provides seafood nationwide. All of our most profitable species use wetlands for some part of their life cycle.  For example, shrimp spawn in estuaries, crawfish spend their whole semi-aquatic lives in freshwater wetlands, and oysters occupy coastlines while providing some wave attenuation and water filtration. CWPPRA and our partners see oysters as an alternative method to protect our some parts of our coast with artificial reefs that can also be harvested, making them a highly sustainable food source. Some foods we receive from wetlands aside from seafood include turtles and ducks in some cases, rice (a staple in many cultures worldwide), and a wide array of other plants for their tubers or berries.
Beyond the food, though, wetland benefits include flood protection to our major cultural hubs and carbon sequestration. Sequestering carbon makes wetlands wildly productive and an ally in the fight against global climate change.  CWPPRA was written into law in 1990 to help preserve these bountiful ecosystems so they can continue to thrive and benefit people in Louisiana and beyond. This holiday season, even if you are not eating any seafood during your feasts, you are benefitting from wetlands, so say a thank you for all of those natural areas that give us so much.
Recycling is a great practice at home, but it reaches far beyond taking materials out of the waste stream. Tomorrow, November 15th, is designated as America Recycles Day, so today’s Wetland Wednesday is hopeful about the future of sustainability.
New materials require exploration and processing that can be destructive to ecosystems. Plastics, some of the most common materials in the product stream today, are largely recyclable. As a crude oil byproduct, producing new usable plastics requires a lot of energy. The same goes for many other recyclable materials. Paper products, various metals, and glass all take a lot of energy to produce, then they quickly find their way into landfills instead of being reused. Landfills produce a wide array of chemicals that often leach into the ground due to poor containment practices, and they can contaminate watersheds. Once those chemicals get into a watershed, they can significantly decrease the health of wetlands across huge swaths of land over time. To further the polluting effects, drilling for oil to meet a growing desire for fossil fuels is one of the most detrimental practices to wetlands. More than 5 years after the Deepwater Horizon oil spill in the Gulf of Mexico, Louisiana wetlands continued to lose ground due to the spill’s impact. 
Recycling is not a perfect alternative to single-use plastics, and there are other ways to reduce our consumption of resources. For example, mitigating loss of byproducts by finding new and inventive applications can greatly reduce consequences. Large-scale food manufacturing leaves plenty of byproduct as leftover plant material that can be used as livestock feed, potentially as biofuels, or fertilizer. In the meat industry, byproducts are often further processed and commercialized to maximize the use of all parts of animals. CWPPRA and our partners have changed some practices in recent years to be more efficient when using resources, for example beneficial use of dredged material (yes, we recycled our header image). Mandatory dredging of shipping and navigational channels produces a bounty of sediment that was lost in the past, but we can now use that material in restoration projects. This exciting new practice has already been implemented in a few CWPPRA projects to restore marshland and nourish pre-existing wetlands.
Our coast faces many human-caused threats, and its future depends, in part, on practices becoming more sustainable. By using new technologies to better use resources, CWPPRA hopes that Louisiana’s natural splendor and resilience can continue to benefit future generations.
Gulfside and bayside erosion has resulted in the narrowing of Whiskey Island (and the entire Isles Dernieres chain) as the two shorelines migrate toward each other, resulting in a 68 percent decrease in average width for the Isles Dernieres. Within 100 years, the entire subaerial portion of the Isles Dernieres barrier island system is expected to disappear except for small land fragments associated with the western end of Whiskey Island and the eastern end of East Island. However, some estimates project the Isles Dernieres will disappear much earlier. Other predictions suggest that, without restoration, Whiskey Island could become a subaqueous sand shoal by 2019. Another CWPPRA restoration project, Whiskey Island Restoration (TE-27), which included placement of dredge material, vegetative planting, and sand fencing, was completed in 2000.
The goal of the TE-50 project is to increase the longevity of the previously restored and natural portions of the island by increasing the island’s width. Increasing the island’s width will help to retain sand volume and elevation. Approximately 319 acres of back barrier intertidal marsh habitat, 5,865 linear feet of tidal creeks, three 1-acre tidal ponds and 13,000 linear feet of protective sand dune were created by semiconfined disposal and placement of dredged material. The sediment was dredged from a sediment source in the Gulf of Mexico near the island. The area was planted with native marsh vegetation to colonize and protect the newly-placed marsh soil.
Whiskey Island, one of five islands that make up the Isles Dernieres barrier island chain, is located 18 miles southwest of Cocodrie in Terrebonne Parish, Louisiana. The island is surrounded by Coupe Colin to the west, Whiskey Pass to the east, Lake Pelto, Caillou Boca, and Caillou Bay to the north, and the Gulf of Mexico to the south.
The CWPPRA Task Force approved funding for construction (phase 2) at the February 13, 2008 Task Force meeting. Construction began in March 2009 and initial construction was completed in November 2009.Vegetative plantings were installed at the project site in June of 2010 and October 2011.
According to NOAA, one of our managing agencies, a living shoreline is “A protected and stabilized shoreline that is made of natural materials such as plants, sand, or rock.”  In some situations, living shorelines are a better option than hardened shoreline protection because they have more movement of natural sediment, the ability to grow, and the obvious aesthetic value of a natural area.
‘Living shorelines’ can refer to multiple restoration techniques and coastal environments; for CWPPRA, a living shoreline can mean vegetative planting on a marsh creation cell or using a shoreline protection barrier that promotes oyster reef growth. Living restored shorelines help maintain the integrity of ecosystems, but they also provide benefits to recreation and potentially to commerce. One big push in restoration over the past few years has been artificial oyster reefs which provide wave attenuation, natural water filtration, and a harvestable population of oysters for the seafood industry. 
Vegetated marsh provides similar benefits to artificial oyster reefs and is a tried-and-true restoration strategy. Many marsh creation projects will naturally revegetate thanks to seed banks in borrow sites but some need management to limit invasive species. In more vulnerable sites, CWPPRA actively plants native species like smooth cordgrass and California bulrush to give them an advantage against invasive populations.
CWPPRA understands that successful restoration projects, including shoreline protection, help keep ecosystems intact and productive. A changing coast means we need changing solutions, and we will strive to find better alternatives to maintain the natural environment.
