What is a salt marsh and where can they be found?

A salt marsh is a coastal ecosystem characterized by salt-tolerant vegetation and periodically flooded by seawater, typically found in the intertidal zones of estuaries and along Coastlines. These habitats are essential for biodiversity, providing critical breeding and feeding grounds for various wildlife, including birds and fish. Salt marshes can be found in temperate and tropical regions around the world, often near river mouths where freshwater meets the ocean. They play a vital role in coastal protection, water filtration, and carbon sequestration.
