More than a seafood delicacy, oysters are an incredible natural resource. They are extremely helpful to our environment by filtering water, providing habitat, and controlling erosion. Adult oysters may filter up to two and a… More
The marsh in this area was fairly stable prior to Hurricane
Katrina in August 2005. There was extensive damage to the
marsh along the north shore of Lake Pontchartrain and
especially localized in the marshes near Bayou Bonfouca
when the storm surge removed many acres of marsh. Marsh
loss rates should increase in the marsh surrounding these
newly created open water areas due to an increase in wind
driven fetch. Within the project area, the Lake Pontchartrain
shoreline erosion rates seem to be very low. Currently, there
is one large breach and several smaller ones in the Lake
Pontchartrain shoreline, with many more breaches seemingly
imminent. These breaches provide direct connection between
the fresher interior marshes and higher saline waters of Lake
Pontchartrain. The breaches in the bankline should be filled
before they grow to become a major exchange point causing
an increase in interior loss rates.
The primary goal of the project is to create 533 acres and
nourish 42 acres of low salinity brackish marsh in open
water areas adjacent to Bayou Bonfouca with sediment
pumped from Lake Pontchartrain.
This project would consist of placing sediment, hydraulically
dredged from Lake Pontchartrain, in open water sites to a
height of +1.2 NAVD 88 to create 458 acres and nourish
approximately 133 acres of marsh. Several historic marsh
ponds have been identified and would be restored. Tidal
creeks are also proposed to connect these ponds to facilitate
water exchange and fisheries access. Containment dikes
would be sufficiently gapped or degraded to allow for
fisheries access no later than three years post construction.
The project would result in approximately 424 net acres of
intermediate marsh over the 20-year project life.
This project is located in Region 1, Pontchartrain Basin, St.
Tammany Parish. Parts of the project are located within Big
Branch Marsh National Wildlife Refuge adjacent to Bayou

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.
On June 27th residents of Terrebonne Parish and other concerned citizens gathered at the Houma-Terrebonne Civic Center for the first Terrebonne Parish Coastal Day. This event included educational displays, restoration equipment, informative panels featuring elected officials and coastal experts, and plenty of discussion on levees, floodgates, non-structural risk reduction and restoration. Speakers such as Colonel Clancy of the Army Corp of Engineers and State Senator Norby Chabert described how Terrebonne Parish has been one of the most aggressive parishes in protecting communities and livelihoods by working diligently to get permits and funding for projects in the area. Posters on the walls displayed projects from Amelia to South Lafourche showcasing the work being done to better protect Terrebonne Parish from situations such as hurricanes and flooding. Along with CWPPRA, other exhibitors in attendance included organizations such as the Coastal Protection and Restoration Authority, Restore or Retreat, and the South Louisiana Wetlands Discovery Center. Special guest, Beignet the Nutria, accompanied the South Louisiana Wetlands Discovery Center as a visual reminder of the speed at which nutria eat vegetation and the destruction that this animal can cause to coastal wetlands. Over 700 people were in attendance for this interactive showcase of coastal protection.
The Coastal Wetlands Planning, Protection, and Restoration Act Public Outreach staff attended the event as exhibitors providing information and materials to educate the public on wetland and coastal restoration. Publications such as Partners in Restoration, Understanding CWPPRA, Coastal Wetlands Restoration Residents’ Guide, CWPPRA Posters, and Henri Heron’s Louisiana Wetlands were distributed in addition to editions of WaterMarks and fact sheets featuring projects within Terrebonne, Lafourche, and St. Mary Parishes.
Located in the heart of South America is the world’s largest wetland that has not been significantly modified by humans, the Pantanal. The Pantanal is often referred to as South America’s biggest biodiversity star. However, it is also one of the continent’s best-kept secrets, often overshadowed by the Amazon Rainforest. This massive wetland covers an area estimated at 75,000 square miles across Bolivia, Paraguay, and (mostly) Brazil. The Pantanal is home to over 4,700 species of plants and animals.
The array of life in the Pantanal relies on an annual flooding cycle. When it rains, about 80 percent of the floodplain is submerged underwater; throughout the dry season the water lessens. This process is essential to nurturing a biologically diverse collection of plants and providing nutrients that the wetlands need to flourish. An area that is the size of Belgium, Switzerland, Holland, and Portugal combined needs a lot of water to guarantee that it continues to flood and a healthy ecosystem is preserved. The quality of the water is also important to maintaining a nourishing environment. Recently, human activity has been threatening this precious wetland. The Pantanal is threatened by intensive farming, deforestation, and pollution. Few signs of this situation improving are shown, and environmental issues are difficult to resolve quickly. Conservation of the biodiversity and natural resources of the Pantanal is essential.
The most significant environmental problem affecting the
marshes in this area is deterioration and conversion to open
water. Marsh loss has and continues to occur as a result
of salt water intrusion and sediment export (erosion). The
construction of the Calcasieu Ship Channel and the Gulf
Intracoastal Waterway greatly increased the efficiency
of water exchange through Calcasieu Pass. Freshwater
retention was consequently reduced and salt water is able
to enter interior marshes and penetrate further north and
west. Project-area marshes are connected to the navigation
channels through a network of canals and bayous including
Kelso Bayou and Alkali Ditch. Unvegetated substrate
is vulnerable to increased tidal exchange and immense
quantities of organic substrate are being exported.
Recent marsh loss and scouring at the mouth of Kelso
Bayou from impacts related to Hurricanes Rita and Ike allow
increased salt water intrusion, tidal exchange, and storm
The goal of this project is to restore and protect
approximately 319 acres of critically important marsh
and the numerous functions provided by those areas. The
proposed project will restore a portion of the historic
meandering channel of Kelso Bayou and provide direct
protection to Louisiana State Highway 27, the region’s only
northward hurricane evacuation route. Project features
include creating/nourishing 319 acres of marsh, 3,200 linear
feet of shoreline protection, and rock armor at the mouth of
Kelso Bayou to prevent additional tidal scour.
This project is located in Region 4, Calcasieu-Sabine Basin,
Cameron Parish. The project features are located in an area
south of the Gulf Intracoastal Waterway and just west of the
Calcasieu Ship Channel.
This project is on Project Priority List (PPL) 20.

National American Eagle Day is observed each year on June 20th. This day is celebrated in honor of our national symbol, to raise awareness for protecting the bald eagle, to assist in the recovery of their habitat, and to educate Americans on their significance. The bald eagle can be sighted during its breeding season at nearly any wetland habitat such as seacoasts, rivers, large lakes, or marshes. You can find these eagles around large bodies of open water with an abundance of fish.
In the mid 20th century, America’s precious eagles were almost lost due to the effects of habitat destruction, poaching, and environmental negligence, specifically the contamination of food sources by the pesticide DDT. Thanks to conservation efforts of various organizations, conservationists, and protection laws – the bald eagle populations recovered. Habitats restored through CWPPRA projects aided in the delisting of our national symbol from the endangered species list in 2007. CWPPRA has protected, created, or restored approximately 97,177 acres of Louisiana’s vanishing coastal wetlands in its first 25 years. Those restored swamps, marshes, barrier islands/headlands, and associated open-water habitats provide foraging, nesting, breeding, wintering, escape cover, and nursery habitat for wildlife, in particular the American bald eagle.
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.
