Submerged aquatic plants, often dismissed as “weeds,” are essential to the freshwater ecosystems of lakes and rivers. Known scientifically as macrophytes, aquatic plants absorb nutrients like phosphorus and nitrogen which otherwise can fuel algal blooms. They also stabilize lake-bottom sediments, help protect shorelines from wave erosion, and provide critical habitat and food for fish and other wildlife. Because aquatic plants play such a vital role, the Wisconsin Department of Natural Resources (DNR) regulates and limits their removal to preserve the numerous benefits they bring to our waterways.
