Wetlands: about this Topic Coastal wetlands, a fragile transitional zone between marine and terrestrial environments, have significant economic and ecological value. They are the most productive ecosystems known, providing nutrients and habitats that support the entire coastal ecosystem. Most of the Nation's coastal commercial and recreational fisheries depend upon wetlands for spawning, hatching, and nursery activities. Coastal wetlands also play vital roles as habitats for wildlife, waterfowl, and migratory birds. Other related USGS websites: National Wetlands Research Center
