For 25 years, the Coastal Wetlands Planning, Protection, and Restoration Act has provided the only joint Federal/State coastal restoration effort with a predictable and recurring funding stream designed to restore the vanishing wetlands of coastal Louisiana. The CWPPRA program continues to pursue a full slate of coastal restoration activities, and its progress and experience provide the foundation for restoration supported by one-time funding from various other sources. CWPPRA represents a collaborative effort and is managed by a Task Force comprised of five federal agencies and the State of Louisiana. CWPPRA’s Managing Agencies include:
In honor of October 3rd, World Habitat Day, this Wetland Wednesday will discuss wetlands as a habitat!
Louisiana wetlands are essential in providing habitats for wildlife. For some wildlife, the only fitting habitat that adequately provides all needs and resources to survive are wetlands. Different types of wildlife rely upon different types of wetland habitats such as swamp, freshwater marsh, intermediate marsh, brackish marsh and salt marsh. The Great Egret and Great Blue Heron can be found in freshwater marshes along with wood ducks, while Brown Pelicans, the state bird of Louisiana, are most frequently found in intermediate marshes. Seasonal migration pathways also rely heavily upon the sustainability of wetland habitats. Louisiana’s coast provides a critical habitat and resting point for waterfowl in route along the Mississippi Flyway during migration; about 40% of all North American migrating waterfowl and shorebirds use this route. The Coastal Wetlands Planning, Protection, and Restoration Act continues to work to enhance, restore, and protect these imperative habitats for the nation’s wildlife!
In honor of National Estuaries Week, this week’s Wetland Wednesday focuses on
An estuary is an ecosystem comprised of both the biological and physical environment, commonly located where a river meets the sea. Estuaries are known to be 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. 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 successful recreational activities such as fishing. Celebrate National Estuaries Week by aiming to keep your estuary areas clean of trash for others to enjoy as well as a healthy environment for wildlife and vegetation!
There are four different types of wetland marshes in Louisiana.
Due to Louisiana’s proximity to the Gulf of Mexico, the exchange between fresh and salt water along the coast is frequent. Depending on the location of the marsh, it could be classified as either freshwater, intermediate, brackish, or saltwater marsh. Marshes are categorized by the salinity, or salt content, of the water, and the location of marshes to the Gulf of Mexico often directly correlates with the salinity level. Generally following a salinity gradient, freshwater marshes are commonly situated furthest inland from the gulf with a salt content of 0 ppt (parts per thousand), intermediate marshes contain a salinity range of 0-5 ppt, brackish marshes have a range of 5-15 ppt, and saltwater marshes encompass a salt content of 15 ppt or greater. Within the marsh gradient are estuaries, where fresh and salt water mix and many wetland species spend their juvenile lives.
