Wetlands in the Coastal Plains are vital for several reasons, primarily because they filter water and support biodiversity.

By storing pollutants and silt, wetlands serve as natural sponges that absorb excess rainfall and runoff, thus improving the quality of the water. Drinking water supplies and downstream ecosystems are safeguarded by this filtering process. Wetlands also offer vital homes for a wide variety of animals, such as insects, fish, birds, and amphibians. Because these ecosystems support a variety of species at different phases of life, they are essential for preserving biodiversity. Wetlands provide numerous advantages to communities and the environment, and their preservation is essential to the Coastal Plain's health.
