31 Key Functions of Riparian Vegetation Dissipate Energy / Reduce Erosion Trap Sediment / Build Floodplain Increase Water Storage - Riparian Sponge Slow Down the Water

33 How to Maintain or Restore Riparian Areas: Creeks / Riparian Areas are special places; they need preferential treatment Identify the factors that inhibit recovery; Manage to overcome those barriers

34 Hindrances to Healthy / Functional Riparian Areas: Farming too close to the bank Mowing, spraying close to the creek Manicured landscapes next to the creek Chronic grazing concentrations in creek areas Excessive deer, exotics, hogs in creek areas Removal of large dead wood Artificial manipulation of banks / sediment Excessive vehicle traffic in creek area Excessive recreational foot traffic in creek area
