Biological Diversity

Today, CWPPRA celebrates the International Day of Biological Diversity and the variety of species Louisiana’s coastal wetlands! Louisiana’s wetlands boast a wide array of ecosystems, including upland hardwood forests, forested wetlands known as swamps, salt and freshwater marshes, and barrier islands, that allow for species to thrive and diversify into specialized niches.  Throughout the United States, we all benefit from Louisiana’s wetland biodiversity, especially the abundance of fresh fish and seafood species.

The fact that we have so many desirable species in our coastal waters is a huge benefit to the state’s economy, and the seafood industry provides many Louisiana residents with job opportunities. Louisiana fisheries contribute about $2.4 billion to our economy each year. About $1.3 billion of that sum is directly from the shrimp catch. Recreational fishing is a popular pastime in this area as well, which is supported by wetland habitats. Our rich diversity allows for people to choose from a variety of prey. Many fishermen diversify their catches so that if one species limit is reached or season is passed, they can collect other species. Limits are put in place to keep populations stable, which maintains ecological interactions and the vibrant ecosystems we are so proud of. For more information about limits and fishing licenses, visit the Louisiana Department of Wildlife and Fisheries.

From the flavor of the meat, to the number of bones, each species has different value to fishermen and consumers. Differences in physiology and morphology between fish in our coastal waters are as abundant due to our biodiversity. We have bony fish and cartilaginous fish, plant- and meat-eaters, fresh and saltwater species, fish with or without spines, and the list goes on and on. These different types of fish coexist because our coast is so productive. Normally, ecosystems evolve predictably as populations move and change size and they are resilient to an extent. However, large-scale disturbances that interrupt the natural interactions and processes—like the sudden proliferation of an invasive species, man-made disasters like the Deepwater Horizon oil spill, and large weather events—can cause major problems for our native species.

Diversity is an important factor in a healthy ecosystem and Louisiana is fortunate to have our abundant and protective coastal zone, but we are losing these important habitats to land loss. Land loss affects the diversity of our species and the industries that rely on these species. CWPPRA is dedicated to make sure our projects have a positive impact on our native species of plants and animals before construction begins. CWPPRA strives to protect the natural splendor that makes Louisiana the “Sportsman’s Paradise” for generations to come.
