Description

What is a wetland?Wetlands are strategically placed to capture surface runoff and drainage water. They provide temporary storage for floodwater which lowers downstream flood peaks and reduces streamflow by 10-20%. Additionally, they reduce nitrate-N concentration in water by 52% and filter out chemicals from pesticides and insecticides. Wetlands also serve as wildlife habitat for 190 amphibian species and 5,000 plant species.
