The Town's utilizes the Lyons Integrated Weed Management Plan, to guide weed management practices. The Town employs weed control measures on:

  • Over 90 acres of community & neighborhood parks
  • Over 135 acres of open space
  • Over 5 miles of trails
  • Public roads and right-of-ways in town limits

The Town of Lyons' weed management plan is an integrative approach, consisting of mowing, hand-pulling, herbicide application, cultural control, and public outreach and education. The objective of the plan is to minimize the occurrence of weeds and the associated negative impacts on native plant communities, public lands, and public corridors within Lyons.

By utilizing an integrative approach to weed management, the Town strives to prevent the introduction of new invasive plant species, eradicate isolated or limited populations, and contain and manage weed species that are established within Lyons.


  • Minimize the occurrence of weeds and associated negative impacts on native plant communities, nearby open space lands, agricultural lands, and public corridors.
  • Utilize an integrative weed management approach to prevent the introduction of new invasive plant species and to contain and manage weed species that are established within the county.
  • Promote education and awareness of new and potential invasive weed species.
