​​​​A tractor pulling a mower mows alongside a state highway.​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.

​Mowing g​o​als:

  • Support public safety, especially at intersections and curves
  • Provide safe areas for vehicles to pull off roads in emergencies, and clear recovery zones for errant vehicles that leave the roadway
  • Balance the need to manage invasive species with overall aesthetics and budgetary limitations
  • Protect wildlife, preserve and encourage native wildflowers and grasses
  • Preserve Wisconsin's natural beauty
