Coastal wetlands are unique ecosystems found along coastlines where land meets water. They include areas like marshes, swamps, and estuaries, which are characterized by the presence of saltwater or brackish water. These wetlands play a crucial role in filtering pollutants, providing habitat for diverse wildlife, and protecting shorelines from erosion and storm surges. These ecosystems are home to various plant and animal species, including mangroves, salt marsh grasses, and numerous birds and fish. Coastal wetlands also serve as important breeding and feeding grounds for many marine species, contributing to the overall health of coastal and oceanic environments.
