In a recent government meeting, experts discussed ongoing research into the management of a cyanobacterium known as Microcystis woollyi, which has increasingly affected the shorelines of Lake St. Clair since its identification in 2010. The organism, more closely related to bacteria than to plants, has been linked to unsightly growths and unpleasant odors along the lake, prompting concerns from local residents.

The study, initiated in December 2022, aims to identify the sources of Microcystis woollyi, understand its accumulation on shorelines, and develop effective management strategies. Stakeholders, including state agencies and academic institutions, have collaborated to establish research priorities and conduct field sampling to fill knowledge gaps.

Researchers are employing advanced techniques such as environmental DNA sampling, autonomous underwater vehicles, and satellite imagery to assess the organism's presence and growth patterns. They are also investigating the nutrient dynamics in the lake, focusing on nitrogen and phosphorus levels that may contribute to the cyanobacterium's proliferation.

The project is set to culminate in an adaptive management plan that will explore nutrient sequestration methods and evaluate the use of EPA-registered algaecides to control Microcystis woollyi biomass. The first year of the study included a comprehensive literature review and initial sampling, while the current year focuses on detailed fieldwork and data analysis.

The findings from this research are expected to provide valuable insights into managing the ecological challenges posed by this organism, ultimately aiming to restore the aesthetic and environmental quality of Lake St. Clair's shorelines.
