Colorado's Noxious Weed Program
Noxious weeds are aggressive, non-native plants that pose a serious threat to Colorado's natural landscapes and agricultural areas. They outcompete native vegetation, reduce crop yields, contribute to soil erosion, and increase the risk of devastating wildfires. Our Noxious Weed Program is dedicated to controlling these invasive species and protecting our state's valuable resources.
Our Approach to Weed Management
We employ a comprehensive strategy to combat noxious weeds, focusing on:
Prevention: Stopping new invasive species from establishing in Colorado.
Eradication: Eliminating isolated or limited populations of existing invasive species.
Containment & Management: Controlling and mitigating the impact of widespread, well-established invasive species.
How We Achieve Our Goals
To accomplish these critical objectives, our program works collaboratively by:
Coordinating Efforts: Bringing together local, state, and federal noxious weed managers.
Providing Funding: Offering financial support for local, on-the-ground weed management projects.
Education & Outreach: Conducting and supporting activities that raise awareness and educate the public about noxious weeds.
Interstate Collaboration: Maintaining close contact with neighboring states and counties to prevent the spread of noxious weeds across borders.
