Noxious Weeds & Invasive Species Management on Open Space

Management

The weed management program is responsible for weed control on:

  • 25,000 acres of land designated as natural areas
  • 7,000 acres of agricultural leased land that serves as wildlife habitat
  • 685 miles of county maintained road right-of-way

The weed crew utilizes an integrated management approach consisting of herbicide application, mowing, hand pulling, insect bio-control, and cultural control.

Planned Herbicide Applications

Herbicides that may be used, weather permitting, are Escort XP, Esplanade, Glyphosate Pro 4, Habitat, Hardball, Milestone, Opensight, Overdrive, Redeem, Telar XP, Transline, and Tordon 22k.

Management Goals

  • Minimize the occurrence of weeds and associated negative impacts on native plant communities, agricultural lands, and public corridors.
  • Utilize an integrated weed management approach in order to prevent the introduction of new invasive plant species, eradicate isolated or limited populations, and contain and manage weed species that are well established within the county.
  • Stay current with weed management research and innovative management techniques that may increase effectiveness of weed control and/or decrease environmental impacts.
  • Promote education and awareness of new and potential invasive weed species.

What You Can Do

  • Identify Noxious Weeds and do not plant them in your garden. If they already grow in your garden, remove them.
  • Report Noxious Weeds on private property.
  • Volunteer with Parks & Open Space
  • Educate friends and neighbors who have these plants growing on their properties. Their plants will likely spread to your property.
  • Minimize spread of weeds on open space by staying on the trails, feeding horses weed free hay, and cleaning weed seeds from your hiking boots or bicycle tires before recreating on open space property.
  • Attend a Weed Identification and Management Workshop through CSU Extension.
