Nonpoint source: Wetland/Riparian Management
Wetlands and riparian areas typically occur as natural buffers between uplands and adjacent water bodies. They act as natural filters of nonpoint source pollutants, including sediment, nutrients, pathogens and metals, to waterbodies, such as rivers, streams, lakes and coastal waters. It is important to preserve and restore wetlands and riparian areas because these areas can play a significant role in managing adverse water quality impacts. Wetlands, including depressional wetlands, and riparian areas help decrease the need for costly stormwater and flood protection facilities.
