Importance and Benefits of Salt Marshes

Salt marshes are crucial intertidal wetlands that support coastal ecosystems by providing habitat, stabilizing shorelines, and filtering water. They are found globally, especially along the US coasts. These marshes face threats from development, pollution, and rising sea levels, leading to ecosystem disruption. Conservation is vital to maintain their ecological benefits and protect against climate change impacts.
