Saltwater wetlands, such as salt marshes and mangroves, are commonly found along U.S. coastal areas.

Saltwater wetlands are located in coastal zones where saltwater from the ocean mixes with freshwater from rivers and streams. These wetlands, including salt marshes and mangroves, play a vital role in protecting shorelines from erosion, improving water quality, and providing habitats for various marine species. While freshwater wetlands and forested wetlands are found inland, and peat bogs are typically found in colder regions, saltwater wetlands are distinctively coastal features in the U.S.
