Wetlands provide important ecological, economic and social benefits. They provide habitat for fish, wildlife and plants, reduce flooding, and support cultural and recreational activities. Wetlands are commonly identified using familiar terms such as marsh, swamp, bog, bank, or meadow, occurring within or near different types of watercourses. Connecticut has very specific legal definitions for tidal wetlands and inland wetlands, which differ from the federal definitions and may differ from the definitions used in other states.
