WisDOT’s mowing strategies and policy strive to balance budgets, animal activity, invasive species and declining pollinators. WisDOT’s long-standing
natural roadsides mowing policy focuses on preventing the spread of invasive species and promoting the growth of native plants. This approach encourages minimal mowing and the preservation of native vegetation when possible. Mowing is completed by county highway crews.
