Ecologists and state officials are highlighting the role of native aquatic plants in maintaining lake health and water clarity. While many property owners view these plants as a nuisance or "weeds" and remove them using chemicals or machinery, experts from the Minnesota Department of Natural Resources (DNR) and the University of Florida state that these species are essential components of lake ecosystems.
The efforts to change public perception come as property owners clear lakefronts for swimming and boating. In Minnesota, state law allows for the removal of some aquatic plants to facilitate lake access. However, officials report that the widespread removal of these plants can lead to unintended environmental consequences, including increased water turbidity and shoreline erosion.
Donna Perleberg, an aquatic plant ecologist with the Minnesota DNR, stated that native plants help keep water clear by anchoring the lake bottom with their roots, which prevents sediment from being stirred up. These plants also absorb nutrients from lawns, golf courses, and farm fields that would otherwise fuel algae blooms. Jay Ferrell, director of the University of Florida’s Center for Aquatic and Invasive Plants, added that native species support a "rich environment" for snails, crayfish, and insect larvae, and their presence helps prevent invasive species from dominating the water.
Additionally, the methods used to clear lakes have implications for water quality and chemical exposure. Baird reported that some chemical pesticides applied to lakes contain PFAS, also known as "forever chemicals" because they do not break down easily in the environment. Residents who rely on these lakes for recreation or live along the shore would be directly impacted by the introduction of these substances into the water.
What happens next depends on individual property owner choices and state-level permitting. While many states currently allow for partial plant removal, officials are working to educate the public on the benefits of diverse aquatic ecosystems, such as bladderworts and water lilies.
