Invasive Species Management Program

Formally established in 2015, the Centennial Valley Association’s Invasive Species Program monitors and treats noxious weed infestations in the valley, allowing us to maintain and protect intact native plant communities, quality forage for both livestock and wildlife, and ensure that the Centennial Valley remains one of the most pristine landscapes in Montana. To ensure that the Centennial remains relatively weed-free, our Invasive Species Management Program supports collaboration between dedicated landowners, The Nature Conservancy, Red Rock Lakes National Wildlife Refuge, the University of Utah’s Taft-Nicholson Center, Beaverhead County, and state and federal agencies. We follow an Early Detection, Rapid Response model to map and treat both new and existing infestations throughout the Centennial Valley, and incorporate chemical, biological, and cultural treatment methods. The CVA also sponsors volunteer work days and education events, demonstrating that efforts are most successful when they stem from collaborative management across our shared landscape.

    1. Prevent the establishment of new invasive species and manage currently established invasives to prevent them from spreading.

    2. Increase the degree of involvement and literacy on invasive species among community members and visitors to the Centennial Valley.

    3. Develop effective partner strategies to utilize advancements in mapping technologies and invasive species control methods.

    4. Reduce bareground soils to encourage native plant establishment and recruitment.

  • • Mapping weed locations on public lands and along right-of-ways.

    • Organize CVA Sponsored Community Spray Days and Weed Weeks.

    • Promote invasive species education and outreach.

    • Reseeding bareground soils.

    • Facilitate collaborative weed management across county and state borders.

    • Present annual updates on infestations in the Centennial Valley.

  • • Increased landowner outreach efforts and participation at Community Spray Days.

    • Increased collaborative efforts and information sharing between Centennial Valley Invasive Species Program partners.

    • Coordinate and host at least three additional Community Spray Days in the Centennial Valley.

    • Establishment of healthy native plant communities in post-treated bareground and infestation sites.
