A wetland is an area of land that is saturated with water, either permanently or seasonally, such that it takes on the traits of a distinct ecosystem. First and foremost, the factor that distinguishes the wetlands from other land forms or water bodies is the unique vegetation that has adapted to its characteristic soil conditions. The wetland consists mostly of hydric soil, which is supportive of aquatic plants. The water that is found in wetlands can be saltwater, brackish, or freshwater....
