Wetlands have long been considered an obstruction to development. Nearly a century ago, it was believed that wetlands did not provide substantial benefits to the environment and were deemed worthless. Wetlands were drained or filled to make room for further development, such as roads and homes. Today, scientists recognize the environmental benefits that wetlands provide and are encouraging us to preserve this environmental resource. Although we are still losing wetlands, our improved understanding of this dynamic ecosystem and the benefits it provides seems to be contributing to a decreasing loss of wetlands.
Wetlands are valuable in the fact that they provide water purification, flood protection, erosion control, groundwater recharge and discharge, and streamflow maintenance. Along with these benefits, wetlands provide habitat for a large percentage of threatened and endangered species, as well as fish and other wildlife. How a particular wetland functions and benefits the environment depends on its location and type. Wetlands take many forms including marshes, estuaries, bogs, lakes, coral reefs, and floodplains, just to name a few. Wetlands also provide recreational benefits, such as fishing, birding, nature photography, hiking, and kayaking. If you are feeling anxious to seek outdoor activity, look no further than the wetlands near you.
A partially filled or otherwise damaged wetland only reaches its minimal potential to provide all of these environmental benefits. If we want wetlands to continue to perform their ecological functions to the best of their ability, we have to protect them. Take action to help preserve one of the most biologically diverse but undervalued ecosystems.
Animal diversity in the wetland biome is greater than in any other biome type.
Wetland biomes are the perfect place for a variety of plants and animals to thrive due to the climate, food availability, and shelter provided. Amphibians and reptiles do particularly well in this environment. Some reptiles, such as turtles, need wetlands because they either live in water for much of their lives or largely rely on water for their survival. Wetlands support a variety of animals that provide plentiful food sources for reptiles. Snakes spend time around rivers and wetlands where there are food sources such as frogs and bird eggs.
Other species that populate the wetland biome are birds. Wetlands are an important habitat for birds that are breeding, nesting, and rearing young, and some bird species, stop to feed in wetlands along their migration route. The value of a wetland to a specific bird species is dependent upon the presence of surface water and the duration and timing of flooding, for example great egrets may nest in trees above water for protection from predators. The geographic location of a wetland also determines how and when birds will use it.
Alligators and crocodiles are the largest animals found in the wetland biome. The type of water found will strongly affect the types of life that survive there. When salt is present in the water, you might find shrimp and shellfish which are some of the smallest wetland animals.

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.
The marsh boundary separating Lake Borgne and the MRGO
has undergone both interior and shoreline wetland losses due
to subsidence, impacts related to construction and use of the
MRGO (i.e., deep draft vessel traffic), and wind-driven
waves. Although much of the project area is protected from
edge erosion by shoreline protection measures, and since
2009, the MRGO has been deauthorized for deep draft
navigation and maintenance, interior wetland loss due to
subsidence continues to cause marsh fragmentation and pond
enlargement. Wetland loss rates in the project area are
estimated to be -0.60 percent a year based on USGS
The proposed project will create and nourish 634 acres of
marsh using dredged sediment from Lake Borgne. Existing
high shorelines along Lake Borgne, remnants of previous
containment dikes and marsh edge, would be used for
containment to the extent practical. Constructed containment
dikes would be breached/gapped as needed to provide tidal
exchange after fill materials settle and consolidate. The
project would create 346 acres of marsh and nourish at least
288 acres of existing fragmented marsh. A target fill
elevation of +1.2 feet is envisioned to enhance longevity of
this land form. Additionally, 187 acres of vegetative planting
will occur within the newly created areas. Due to the
presence of existing banklines, dredged slurry overflow
could potentially be discharged immediately adjacent to the
project polygons, resulting in nourishment of additional areas.
This project is located in Region 1, Pontchartrain Basin, South Lake Borgne Mapping
Unit, St. Bernard Parish, north bank of the Mississippi River
Gulf Outlet (MRGO) in the vicinity of Shell Beach.
This project is on Project Priority List (PPL) 24.

Oceans are often seen as the blood of our planet. Oceans flow over nearly three-quarters of the planet, providing 97% of the Earth’s water. Not only are oceans a home to an array of marine wildlife, they create a livable environment for land-bearing organisms like humans. Even though most people do not venture far beyond the coast, the open ocean produces a massive scope of goods and services that are a fundamental part of our health, economies, and even our weather.
Marine fisheries, shipping routes, oxygen, carbon dioxide sinks, temperature, weather control, and the water cycle are all provided by the ocean and are essential to a functioning world. Ocean-based businesses contribute more than $500 billion to the world’s economy and approximately half of the world’s population resides in the coastal zone. Oceans supply food, transportation, jobs, and products that aid in keeping people warm, safe, informed, and entertained. Around 90% of all trade between countries is carried by ship. If the ocean cannot produce it, it can at least transport the goods.
Tomorrow, June 8th, people from around the world will join together in celebration to honor, help protect, and conserve the world’s oceans. The theme for this year’s World Oceans Day is “Our Oceans, Our Future.” What a suiting theme! Regardless of our distance from the ocean, our lives are still highly affected by the health of Earth’s oceans. Oceans generate most of the oxygen that we breathe, provide food for us, regulate our climate, and clean the water that we drink. Without maintaining healthy oceans, our future will be affected dramatically.
Celebrate World Oceans Day by adopting the practice of appreciating our oceans through plastic pollution prevention and cleaning the ocean of marine litter. Take care of the oceans that give so much to us in return!
The coastal restoration community has long recognized the benefits of vegetative plantings in restoration. Many marsh creation and most terracing projects require plantings to insure success. Coastal shoreline plantings have also proven to be very effective and some have demonstrated the ability to not only stop shoreline erosion but to facilitate accretion, the process of increasing sediments. Recent hurricane events have exposed a need to have a mechanism in place where large-scale planting efforts can be deployed in a timely manner to specifically targeted areas of need, anywhere along the coast. Although the CWPPRA program can fund specific large-scale planting projects, the normal program cycle for individual projects can delay needed restoration plantings for a number of years.
The goals of this project are to facilitate a consistent and responsive planting effort in coastal Louisiana that is flexible enough to routinely plant on a large scale and be able to rapidly respond to critical areas of need following storm or other damaging events. This project set up an advisory panel consisting of representatives from various state and federal agencies who would assist in the selection of projects for funding. The project also set up a mechanism by which project nominations would be submitted for consideration. The equivalent of 90 acres of interior marsh and 40,000 linear feet of coastal shoreline will be planted per year over a 10 year period to effectively create/protect a total of 779 net acres of marsh over the 20-year project life.
The project features are located in the coastal zone of Louisiana.
This project is on Priority Project List (PPL) 20.

For centuries, Louisiana has had a prospering commercial seafood industry. The catching and selling of shrimp, crabs, oysters, alligator, fish, and crawfish have sustained the livelihood of many families. As one of the country’s largest seafood suppliers, Louisiana contributes more than 850 million total pounds of high-quality seafood to restaurants and homes across the world each year.
Louisiana’s fisheries are an integral part of our economy through providing jobs, as well as income and tax revenue. One of every seventy jobs in Louisiana is related to the seafood industry. As a whole, this leaves an economic impact of over $2.4 billion annually for the state of Louisiana. For many of the industrious fishermen who work Louisiana’s waters, their craft of bringing the finest seafood to the plates of people around the world has been passed down for many generations.
What makes Louisiana waters so plentiful? The abundance of seafood caught and served around the world all starts with our estuaries. An estuary is an ecosystem commonly located where a river meets the sea. Estuaries are inhabited by an array of plant and animal species that have adapted to a mixture of fresh and salt water caused by tidal flow. This changing mixture makes estuaries a fertile region for a variety of marine life. Along with estuaries providing an abundance of seafood, they also provide access to recreational activities and breeding and migratory locations and shelter for fish and wildlife.
Did You Know?
- 75% of the United States commercial sea catch comes from estuaries.
- 37% of estuary marshes in the United States are in Louisiana.
- Louisiana is the largest commercial fishery in the United States.
- Louisiana estuaries comprise the seventh largest estuary in the world.
You can help maintain healthy estuaries by keeping your estuary area clean of trash and robust for our seafood industries, wildlife, vegetation, and others to enjoy! Louisiana’s seafood industry promotes innovations that protect our coastline and help keep our waters clean. When you select Louisiana seafood, you are supporting the lifestyle and environment Louisiana natives have depended on for centuries. As they say about Louisiana seafood, “know better, eat better.”
