What is the term used for the swampy areas found in the southeastern United States, known for their changing water levels?

The term that specifically refers to the swampy areas found in the southeastern United States, characterized by their unique ecosystems and fluctuating water levels, is "bayous." Bayous are typically slow-moving waterways or marshy areas, often featuring a mix of freshwater and saltwater, and are prominently associated with regions like Louisiana. They play a crucial role in the local environment by serving as habitats for a diverse range of wildlife and helping in flood control. The distinct characteristics of bayous, including their rich biodiversity and significant cultural importance, make them a notable feature of the landscape in the southeastern U.S. Other terms, while related to wetland environments, do not capture the specific characteristics and local significance of bayous.
