Navigating wetlands can be difficult for traditional boats due to the changes in water depth and the amount of mud and muck, as well as the meandering of the waterways. Because of these complications, boats that travel both over land and water are needed to explore coastal wetlands. The creation of airboats and innovations in their design have allowed for greater exploration of wetlands and are vital to CWPPRA’s wetland restoration.
Airboats evolved since their introduction in 1905 by Alexander Graham Bell, who is also credited as the inventor of the telephone. His first model was named the “Ugly Duckling”, a crude test vehicle that incorporated an aircraft propeller mounted on the back of a simple pontoon boat. Over the next decade, further developments turned airboats into World War I reconnaissance vessels. Following the end of the war, commercialization led to a rise in popularity among civilians with companies designing taxis and recreation vessels alongside independent innovators creating their own airboat designs. One of the most revolutionary models was built in 1943 at Bear River Migratory Bird Refuge in Utah and dubbed the “Alligator I”. This design was the first known to use air rudders rather than traditional rudders, and most airboats today replicate the Alligator I’s flat bottom hull with air rudders. 
Thanks to the inventors at Bear River, Louisiana’s wetlands are more navigable than ever. Further developments have allowed airboats to pass over land, increased passenger capacity and engine horsepower, allowing those in pursuit of recreation, scientific research, and sport hunting/fishing to reach previously inaccessible parts of our wetlands. CWPPRA teams visit project sites using airboats to help get an idea of problems to be addressed through the duration of projects, ensuring the best quality of restoration for our coast. Restoration and preservation have been made easier with creative solutions like airboats, so we would like to recognize the innovators who worked a century ago to improve upon each other’s designs. Once again, the land loss crisis and need for wetland restoration in Louisiana is too large for us to do it alone. We need all the help we can get from innovators like those at Bear River Migratory Bird Refuge to help restore our coast.

Summer Recreation in the Wetlands
Are you looking to engage in outdoor fun this summer? Well, look no further. This Wetland Wednesday will give you plenty of ideas on how to enjoy the sunshine while spending time in one of Louisiana’s vibrant ecosystem.
One of our wetlands’ greatest qualities is providing outdoor recreation. During the summer, wetlands attract visitors of all ages to partake in boating, fishing, canoeing, photography, bird-watching, or simply enjoying the beauty of nature. Louisiana, often called “Sportsman’s Paradise,” earned this nickname due to its rich history of sports and recreation that takes place along its beautiful marshes and bayous.
This summer, The Coastal Wetlands Planning, Protection, and Restoration Act encourages the public to spend time in the wetlands that have made Louisiana an attraction worldwide. While utilizing the wetlands, be mindful of the wildlife and participate in keeping our wetlands healthy and clean.
While there are some people who cannot spend enough time outdoors, enjoying all of nature’s gifts, there are others who need a little more motivation to get outside and seek the beauty of our outdoors. What better time for either party to embrace the outdoor spirit of America than in the month of June, Great Outdoors Month. The month kicks off with a Presidential Proclamation, which advocates for all Americans to visit the great outdoors and to protect our nation’s legacy by conserving our lands for future generations. The Proclamation discusses the numerous possibilities for Americans to explore, play, and grow together through outdoor activities. Any activities from hiking to canoeing to wildlife watching, hunting, or fishing can involve kids by being healthy, active, and energized.
More and more Americans are seeking healthy and fun outlets as ways to stay active. The outdoor recreation community is situated in an exemplary position to help people lead a healthier lifestyle by welcoming them and providing guidance on how to take advantage of the great outdoors. Wetlands provide recreational opportunities such as fishing, canoeing, hiking, bird watching, and waterfowl hunting, just to name a few. One of the largest and most avid groups of people using wetlands is waterfowl hunters. There are an estimated 3 million migratory bird hunters in the United States. This year, new studies by the recreation community will record data on the key role outdoor recreation plays in local, state, and national economies. Outdoor recreation is an economic powerhouse in our country generating nearly $887 billion in consumer spending each year and creating 7.6 million jobs. Great Outdoors Month is designed to highlight the benefits of getting involved with our great outdoors and enjoying natural resources, such as forests, parks, refuges, and other public land and waters.
Water, promoter of all life forms on Earth, is recognized today- World Water Day! In Louisiana, 47% of the state’s population resides in the coastal zone, with a majority of livelihoods reliant on water. Industries such as aquaculture, agriculture, oil and gas, and tourism depend on the sustainability and quality of Louisiana’s waters. This essential natural resource has a synergistic relationship with Louisiana’s wetlands, providing vital nourishment to fisheries, wildlife, and Louisiana’s coastal growth. Wetlands improve water quality by trapping suspended solids and filtering other pollutants. Coastal marshes filter excess nitrogen and phosphorus, thus helping to prevent algal blooms and maintaining oxygen in the water for fish and shellfish. Wetlands can retain, remove, and transform nutrients that might otherwise contribute to declining water quality. Clean water is important for healthy fish, wildlife, and humans. Water is not only a commodity, but a contributor to life… appreciate it, preserve it, and protect it!
Water is the key to life, celebrate World Water Day!
The invasive plant, giant Salvinia, was first observed in Chenier Plain marshes in 2009. Since then it has spread throughout most of the Louisiana Chenier Plain marshes. This plant can stack up above the water surface to as much as 6 to 12 inches. Under such conditions, oxygen exchange is greatly reduced, and decay of shaded Salvinia can easily cause anoxic conditions in affected areas. As a result, habitat quality of badly infested areas is severely degraded, and may affect many species typical of fresh marshes, including many species of management concern (alligator snapping turtle, mottled duck [including critical brood rearing habitat], wintering migratory waterfowl, black rail, king rail, little blue heron, whooping crane, and peregrine falcon).
LSU Ag. Center has a pond in Jeanerette, La. which is capable of producing weevil-infested Salvinia, but LSU does not have funding to operate a weevil production facility here. Costs associated with this project consists primarily of supplies and one part-time position to operate the pond, coordinate public weevil harvests, keep records of release locations, monitor Salvinia problem areas, assist landowners in conducting weevil release, relay infested Salvinia to new locations, and conduct public outreach to promote the program.
The Louisiana Salvinia Weevil Propagation Facility project is located coastwide.
This project was approved for Phase I, Phase II, and Operation in January 2017.
This project is on Priority Project List (PPL) 26.

An estuary is an ecosystem comprised of both the biological and physical environment, commonly located where a river meets the sea. Estuaries are inhabited by an array of plant and animal species that have adapted to brackish water—a mixture between freshwater draining from inland and salt water. One of the most expansive and productive estuaries in the world is located in the United States at the interface of the Mississippi River’s freshwater and the salt water from the Gulf of Mexico.
Estuaries have one of the highest productivity rates among ecosystems in the world; they provide an abundance of food and shelter as well as breeding and migration locations. Estuaries also provide great access for enjoyable recreational activities such as fishing. Continue your love for estuaries and contribute to their well-being by aiming to keep your estuary areas clean of trash and healthy environments for wildlife, vegetation, and others to enjoy!
Share the estuary love for Valentine’s Day! #iheartestuaries

This highly invasive, non-native aquatic plant ranks as the second most damaging aquatic weed worldwide. Giant Salvinia (Salvinia molesta), known as the green monster, is a serious threat to wetland ecosystems as it affects a multitude of different factors. While able to be contained in its native country of Brazil, the eradication of Giant Salvinia in the United States proves difficult with respect to legal herbicides.
Giant Salivinia has oblong floating leaves, approximately one-half to one and one-half inches long, with small vertical hairs on the upper surface. This exotic vegetation forms dense concentrations to create a compiled mat formation, often 3 feet in depth. In a time span of three months, with ideal conditions, a single plant can multiply to cover 40 square miles. With such an immensely rapid growth rate, Giant Salvinia can quickly take over a waterway, causing devastating and lasting results. These mats halt the penetration of sunlight into the water and, by doing so, eliminate native competition by smothering nearby plants and phytoplankton. Fish kills occur as a result of depleted oxygen levels due to the lack of phytoplankton, which in turn destroys the value of an area as waterfowl habitat. Along with natural consequences, Giant Salvinia has the potential to block entire waterways, preventing water vessel passage, whether for recreational or commercial purposes.
The Coastal Wetlands Planning, Protection, and Restoration Act realizes the importance of and continues to work toward establishing a successful eradication method for Giant Salvinia. To aid in the prevention of Giant Salvinia expansion, consider discarding any plant fragments from boating equipment and vessels, as well as discarding garden and aquarium plants, in the garbage as opposed to water bodies.
The Teche-Vermilion Basin Project was included in the 1966 Flood Control Act after a 1961 study by Louisiana’s Department of Public Works showed deteriorating water quality and insufficient water in Bayou Vermilion and Bayou Teche. Ground water was threatened with contamination by salt water due to lack of flow of the Teche and Vermilion Bayous. The purpose of the project is to restore the flow of water to the Teche-Vermilion basin, improve water quality through the increased flow, and prevent salt water from entering the lower parts of the basin. The increased flow is also intended to restore the water supply available for agricultural and industrial needs before the protection levees were built. The state legislature created the Teche-Vermilion Freshwater District Board of Commissioners in 1969. The Board of Commissions was charged with responsibility for the maintenance and operations of the original project of the Army Corps of Engineers, as well as major replacements.
On October 21, CWPPRA staff attended the Teche-Vermilion Fresh Water District Annual Inspection Meeting at the Teche-Vermilion Pump Station in Krotz Springs, La. The meeting began with a welcome speech from Donald Sagrera, TVFWD Executive Director. Introductions of property possession parish commissioners were made beginning with Ed Sonnier, Lafayette Parish; Donald Segura, Iberia Parish; Tommy Thibodeaux, St. Martin Parish; Mike Detraz, Vermilion Parish; and Bradley Grimmett, St. Landry Parish. A positive inspections report was given by Darrel Pontiff of Louisiana Coastal Protection and Restoration Authority, as well as Ted Elts of U.S. Army Corps of Engineers. Ed Sonnier, TVFWD Chairman, introduced Lafayette Mayor-President Joel Robideaux, who was the event’s guest speaker. The presentation continued with recognition of TVFWD staff and sponsors given by Cecil Knott, Operations Supervisor, and Alex Lopresto, TVFWD Legal Advisor. TVFWD Executive Director Donald Sagrera ended the ceremony with closing remarks.
On October 15, the U.S. Fish and Wildlife Service hosted the 19th Annual Wild Things Festival at the Southeast Louisiana Refuge Headquarters in Lacombe, La. This exciting family-friendly event gives the community an opportunity to engage in outdoor activities while celebrating National Wildlife Refuge Week. This free public event included canoe and pontoon boat tours, hayrides, live animals, wildflower walks, kids activities, bird house building, live music, and a youth wildlife art competition.
The Coastal Wetlands Planning, Protection, and Restoration Act Public Outreach staff was among the 40 exhibitors providing hands-on activities to encourage knowledge of the Louisiana outdoors. In order to accurately portray the importance of aquatic, coastal regions, the CWPPRA staff utilized an ocean character, Sid the Restoration Squid, whose six unique legs each represented a different restoration method. The six restoration methods include barrier island restorations, marsh creations, shoreline protection, hydrologic restoration, freshwater and sediment diversions, and terracing. Each leg consisted of a distinct craft material that would correspond with a restoration method, in which children would assemble and personalize their own squid. Each child’s personal squid was accompanied by an explanation guide of CWPPRA’s efforts to restore, protect, and/or create Louisiana’s wetlands.
