American Eagle Day

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.

World Turtle Day

On May 23, we celebrated the 17th annual World Turtle Day sponsored by American Tortoise Rescue. This nonprofit organization was established in 1990 to protect all species of tortoises and turtles. They created World Turtle Day to serve as an annual observance of protecting tortoises and turtles around the world and their disappearing habitats. Wetlands that serve as habitat for turtles include shallow fresh waters, pelagic salt waters, and heavily and scarcely vegetated areas. Various species of turtles reside in every type of wetland environment.

Did You Know?

  • The majority of turtles that you see on the road are females traveling to their annual nesting sites.
  • Turtles like to eat dead material lying on the bottom of ponds, lakes, and wetlands. Turtles keep the water clean!
  • Snapping turtles rarely snap at humans in water. They do not like the way people smell or taste.
  • If you are helping a turtle cross the road, be sure to move the turtle in the same direction it was originally headed. DO NOT turn it back around! It is likely it will try to cross the road again.
  • If you touch a turtle, it is important that you wash your hands thoroughly. Turtles may carry salmonella.

How to Protect Turtles?

  • Avoid walking or driving on sandy areas where turtles are nesting.
  • Create a “no wake zone” to reduce damage to shoreline wetland habitats and stop the removal of plant materials.
  • Do not remove turtles from their natural habitats.

What Can You Do?

  • You can put signs and small barriers around nesting sites and wetlands that are on your property.
  • You can contact local programs to help pay for habitat restoration in your area.
  • You can add beneficial features to turtle habitat by planting native plants to buffer wetlands and turtle nesting areas. This will attract frogs, snails, insects, and other species that turtles eat.

World Migratory Bird Day

World Migratory Bird Day was initiated over ten years ago as a way to raise global awareness for the conservation of migratory birds and their habitats. Each year, people around the world organize events, such as bird festivals, exhibitions, and bird-watching excursions to celebrate this day. All activities celebrating World Migratory Bird Day are tied together by a common theme. World Migratory Bird Day 2017 was officially celebrated on Saturday, May 13 with the theme “Their Future is Our Future,” which shed light on the interdependence between people, nature, and migratory animals — particularly birds. The goal of this year’s campaign is to raise awareness of the need for sustainable management of natural resources, including wetlands, demonstrating that bird conservation is crucial for the future of humanity.

Among the wetland attributes society aims to protect and restore are those that benefit wildlife, such as migratory birds. One of the best known functions of wetlands is to provide a habitat for birds to breed, nest, and rear their young. This natural resource is used for drinking water, feeding, shelter, and social interactions. Wetland vegetation provides protection for migratory birds from predators and destructive weather. The presence of an adequate shelter is often crucial to the survival of migratory birds.

The value of a wetland varies for each bird species depending on the amount of surface water, amount of moist soils present, and the duration of flooding. Other factors that commonly affect the value of wetlands to a specific bird species are availability of food and shelter and the presence or absence of predators within the wetland. Availability of water influences whether migratory birds will be present, how the birds will interact with the wetland, and which species will be present. Species of migratory birds may spend the winter months in the Southern United States using the wetlands for food and nutrients to sustain them for their journey north. Many migratory birds are highly dependent on wetlands during the migration and breeding seasons. Habitat loss in breeding areas means population loss for most wetland dependent birds.

Terracing

CWPPRA Restoration Technique: Terracing

The goal of building terraces is to achieve some of the same objectives as full marsh creation but over a larger area of open water, where marsh creation alone is not feasible. Terraces are long, earthen berms that are built by mechanically dredging material and piling and shaping the material to a desired height. Most terraces average around 3 feet tall, with shallow side slopes and a wide base. This size and shape optimize the amount of terrace that falls in the intertidal zone and will support wetland vegetation.

The objectives of constructing terraces are several and depend upon the location in which they are built. These include acting as a sediment trap to help build new land, reducing wave fetch and erosion on adjacent marsh shorelines, creating habitat for fish and waterfowl, and improving water quality to promote the growth of aquatic vegetation. Terracing projects constructed under CWPPRA have achieved each of these goals, with sediment trapping being most evident near the openings of sediment-laden bays or navigational waterways.

Terracing has become a widely used technique that is expanding across the Gulf Coast because of the success and cost-effectiveness demonstrated through CWPPRA and privately funded projects. Although these features may not look like natural marsh and often use geometric configurations, they are able to perform a lot of the functions of natural marsh in areas that have become vast open water. Developing this cost-effective technique for use in areas that have few other restoration options is a testament to CWPPRA’s ability to adapt to funding constraints and a quickly changing environment.

World Water Day

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!

Families Learn about the Importance of Wetlands

Families enjoying a Saturday adventure together on March 11th had the chance to explore different aspects of the ecosystems around them, including ways that wetlands help them and native wildlife. Coastal Wetlands Planning, Protection, and Restoration staff exhibited materials and games at the Estuarine Habitats and Coastal Fisheries Center as part of 2017 Family Adventure Day to benefit the non-profit Healing House in Lafayette, LA. This annual event sends families to different locations throughout Lafayette for experiences that range from face painting to coming face-to- face with a snake.

Over 250 people stopped by the Center where they had the opportunity to see a demonstration of how coastal wetlands protect interior communities and wildlife habitat from storm surge. Visitors could pick up recent issues of WaterMarks and other materials on wetlands restoration projects in coastal Louisiana. Kids also received Henri Heron’s activity book and helped match Louisiana wildlife with the wetland habitat they need to survive.

Other exhibitors, including US Fish & Wildlife Service and Louisiana Dept. of Wildlife & Fisheries, focused on topics like bat conservation, beekeeping, endangered species in Louisiana, and fishing. Helping families understand and appreciate the diversity of natural environments in Louisiana helps ensure that those environments will be present in the future.

Shoreline Protection

CWPPRA Restoration Technique: Shoreline Protection

Louisiana’s shorelines are eroding at a drastic pace, some at rates up to 50 feet per year. The fertile but fragile soils found in the wetlands are susceptible to wave energy. As land is lost, water bodies merge together, which can increase wave fetch and shoreline erosion. Behind these shorelines lie communities, highways, and infrastructure that are at risk of washing away.

Various techniques to defend the coastline have been tested and applied under CWPPRA. Rock revetments, oyster reefs, concrete panels, and other fabricated materials have been constructed along otherwise unstable shorelines to abate wave energy and reduce erosion. These structures are designed to break waves, and they often trap waterborne sediments behind the structures that, over time, can become new land.

Through the course of the CWPPRA program, advancements have been made in shoreline structures that have helped maintain natural processes while providing critical protection. Such advancements have included using lighter-weight materials that require less maintenance and can be constructed on organic sediments. Other advancements include low-relief structures that are designed to trap sediments and natural breakwaters such as reefs that can self-maintain and support other ecological functions. Other natural shoreline protection measures include vegetative plantings, whose roots help secure soils and can promote accretion. These projects are implemented with consideration for minimizing impacts to the surrounding environment. Although some shoreline structures may look foreign in a natural landscape, they are necessary features that physically protect communities and hold wetlands in place by mitigating the harsh forces that move to destroy them.
