Stream + Wetlands Partners with Industry Expert for Algal Bloom Research

Stream + Wetlands (S+W) Foundation is proud to have entered into a partnership with world renowned environmental scientist William J. Mitsch, Ph.D. in an outdoor experimental mesocosm project. Dubbed “wetlaculture” – because it integrates wetlands with agriculture – this multi-year project will study the design of wetlands to decrease downstream eutrophication, including harmful algal blooms and hypoxia, while replacing the requirements of additional fertilization for agricultural production with a recycling mechanism that will return those nutrients to the soil.

A mesocosm is any outdoor experimental system that examines the natural environment under controlled conditions. Mesocosm studies provide a link between field surveys and highly controlled laboratory experiments. Baseline studies involve creating wetland compounds in 30 tubs that will be initially planted with local wetland vegetation to simulate larger-scale wetlands in agricultural settings. S + W’s support will allow the research team to install a mesocosm compound at a site in the Great Black Swamp basin near to the Maumee River in Defiance County.
