A new study provides new insights to demonstrate that multiple wetlands or ‘wetland complexes’ within a watershed are extremely effective at reducing harmful nitrate in rivers and streams. These wetlands can be up to five times more efficient per unit area at reducing nitrate than the best land-based nitrogen mitigation strategies

…Significant research findings include:

….Our work shows that wetland restoration could be one of the most effective methods for comprehensive improvement of water quality in the face of climate change and growing global demand for food,” said study co-author Jacques Finlay, a professor in the University of Minnesota’s Department of Ecology, Evolution and Behavior in the College of Biological Sciences….
