Noxious Weeds

Ecosystem Protection

Colorado is seeing a dramatic increase in noxious weeds. These invasive non-native plants have been introduced by accident or as ornamental plants.  They are devastating thousands of acres of wildlife habitat and natural areas. Left uncontrolled, noxious weeds will form dense monocultures and displace native and desirable plants. Native plant loss affects our ecosystems including wildlife that depends on native vegetation for survival.

Who We Are

Invasive Species Management is the county's program tasked with providing invasive species education and awareness to our landowners and to ensure compliance with the Colorado Noxious Weed Act.

What We Do

Jeffco Invasive Species Management provides technical assistance to private and public landowners to help them develop management strategies for their property. Invasive Species Management helps landowners comply with the requirements of the Colorado Noxious Weed Act.

What Landowners Need to Know

What You Can Do

Good land stewardship is essential to preventing the spread of noxious weeds. As a landowner it is your responsibility to manage noxious weeds. Knowing what is growing on your property is the first step to making sure noxious weeds are controlled.

• Control early when populations are small; don't wait until your entire property is covered with weeds before you realize you have a problem.
• If you have livestock, don't overgraze your property. Overgrazing weakens desirable plants and leaves your land vulnerable to invasion.
• Learn to identify noxious weeds.
• Re-vegetate disturbed areas. Providing good cover helps prevent invasives from moving in.
• Use weed-free hay and mulch. Many infestations are stared when contaminated materials are used.

Weed control is a long-term process. Be patient and practice good land management. Your reward will be a healthy, native-plant community.
