Using a watershed-based approach to wetland protection ensures that the whole system, including land, air, and water resources, is protected. Wetlands found in the United States fall into four general categories—marshes, swamps, bogs, and fens.

wetland plant, is the staple diet of more than half of humanity. The multiple roles of wetland ecosystems and their value to humanity have been increasingly understood and documented in recent years. This has led to large expenditures to restore lost or degraded hydrological and biological functions of wetlands.

Large wetland areas may also be comprised of several smaller wetland types. Wetland habitats serve essential functions in an ecosystem, including acting as water filters, providing flood and erosion control, and furnishing food and homes for fish and wildlife. They do more than sustain plants and animals in the watershed, however.
