Illinois State Park Closes for Invasive Plant Removal Using Drones

Morrison-Rockwood State Park in Illinois will temporarily close its doors to the public on June 23 and 24 to undergo a crucial environmental treatment. The closure is necessary for the application of aquatic herbicides in Lake Carlton, a measure designed to combat the proliferation of invasive lotus plants.

Governor J.B. Pritzker's office announced the closure, stating that park staff will utilize drones to apply the herbicide treatment. This modern approach aims to cover a larger surface area more efficiently and cost-effectively. The intervention is specifically targeted at eliminating the invasive lotus species that have begun to displace native vegetation.

The treatment is expected to yield multiple benefits beyond just removing the invasive plants. Officials anticipate an improvement in the lake's overall ecosystem, creating a healthier habitat for fish. Furthermore, the initiative seeks to enhance recreational opportunities for visitors, making activities such as fishing, boating, and kayaking more accessible and enjoyable.

While the park will be inaccessible to the public during these two days, including camping, the long-term goal is to restore the lake's natural balance. The Illinois Department of Natural Resources (IDNR) hopes that by reducing the monoculture of lotus, a greater variety of native plants will thrive, ultimately benefiting the lake's biodiversity and recreational value.
