RIVER FLOODPLAIN VALUE PROVIDED BY RESTORATION THAT ENHANCES ECOSYSTEM SERVICE VALUE, NUTRIENT RETENTION, AND SUSTAINABILITY.
Rivers and floodplains are complex systems that support many ecosystem services. However, most floodplain systems have experienced decreased connectivity and diminished ecosystem services due to flood and other hardened infrastructure. This infrastructure is aging and degraded, which provides opportunities to enhance ecosystem services as river floodplain infrastructure is repaired and restored. Here we provide several case studies that demonstrate the value of ecosystem services including an estimate for total ecosystem value of restored floodplains, the effects of levee setback on floodplains hydrology and nutrients, and improvements in nutrient retention following legacy sediment removal. Our results from these case studies show that cultural (e.g. recreation and aesthetics) and regulating services (e.g. nutrient retention, erosion control, and flood moderation) were the most valuable with total value of $11,000 to $43,000 per acre per year. We also found that floodplain restoration can enhance physical and biological services including subsurface hydrologic connectivity and nutrient retention. By considering the value of ecosystem services as floodplain infrastructure is repaired and replaced, decisions that lead to more benefits can be realized.
