PV <br />Wetlands intercept precipitation runoff With temporary storage provided in Elepage through the bottom of the <br />and runoff is slowed compared to wetlands,the timing of flood peaks land converts surface water into <br />traveling straight across the landscape. is delayed.undwater. <br />Denitrification — <br />microorganisms convert <br />nitrate to NZ gas which <br />makes up 80% of the <br />atmosphere. Wetland <br />design is typically shallow <br />to promote denitrification. <br />Slower moving runoff <br />produces less soil erosion. <br />The phosphorus -laden <br />sediment that travels with <br />surface runoff is deposited <br />in the wetland as runoff is <br />slowed down. <br />The Iowa Watershed Approach provides 75% cost <br />share for installing wetlands. See your Soil and Water <br />Conservation District or Natural Resources Conservation <br />Service for other cost share opportunities. <br />/ Potential to lease land to hunters for additional income. <br />/ The conversion of wet or low yielding areas into wetlands can <br />make economic sense. <br />F <br />emicals found in pesticides and insecticides are filtered out runoff and drainage water with wetland biota. <br />/ Provides wildlife benefits: <br />• Creates habitat and increases bird populations, including <br />waterfowl, grassland and shore birds. <br />• Increases migration corridors for migratory creatures. <br />• Provides an opportunity to seed pollinator species in wetland buffer. <br />1 Offers recreation opportunities, such as hunting, trapping <br />and bird watching. <br />/ Improves the aesthetic beauty of the landscape. <br />For more information on the Iowa Watershed Approach visit: hfp://www.iihr.uiowa.edu/iwa/ <br />Prepared by Jamie Benning, program manager, and Kristina Craft, program <br />specialist, Iowa State University Extension and Outreach. <br />This project is supported by the Iowa Nutrient Research Center. <br />Iowa State University Extension and Outreach does not discriminate on the basis of age, disability, ethnicity, gender <br />identity, genetic information, marital status, national origin, pregnancy, race, religion, sex, sexual orientation, <br />socioeconomic status, or status as a U.S. veteran.
