What are Wetlands

Wetlands are areas where water is the primary factor controlling the ecosystem. They occur in areas where the water meets the land. In general, wetlands cover a wide variety of natural habitat types including rivers and streams, freshwater or brackish marshes, intertidal areas at estuaries and mangroves. In addition, there are human-made wetlands such as fish and shrimp ponds, irrigated agricultural land, farm ponds, reservoirs and drainage canals.
