John Foret and Joy Merino are coordinating with Louisiana State University's School of Renewable Resources, and Institute of Biogeochemistry to determine the implications of nutrient and water input to Louisiana coastal wetlands. Freshwater reintroduction is increasingly used as a wetland restoration technique in areas where the natural flooding regime has been altered. Freshwater reintroductions are thought to increase plant production by reducing salinity and increasing nutrient availability. Understanding the effect of freshwater reintroductions on marsh plant production is key to determining ecological impacts and best restoration practices. Results will assist restoration planners in determining best locations for diversions and in estimating the area of influence from proposed projects.
