Weed Control

Did you know that Colorado has the Colorado Noxious Weed Act that mandates the management/control of noxious weeds on both private and public lands?

All noxious weeds are non-native species and a plant is named by the State weed advisory board as a noxious weed when it meets one or more of the following criteria:

Aggressively invades or is detrimental to economic crops or native plant communities.

Is poisonous to livestock.

Is a carrier of detrimental insects, diseases or parasites.

The direct or indirect effect of the presence of this plant is detrimental environmentally to natural or agricultural ecosystems. All noxious weeds are invasive due to the lack of natural insects and disease to keep their populations in check. More detailed explanations of each noxious weed occurs with the photographs below.

Since 2005, the Conservation District has been operating the weed management program in Teller & Park counties. We have agreements with both county governments, Colorado Dept. of Transporation, the US Forest Service and other agencies to monitor & treat weeds along all of the state highways, over 2000 miles of county roads, and on public lands in our district. We also assist private landowners with the identification of weeds on their property and provide information on various methods of control or eradication of infestations. For a reasonable fee, our experienced staff can also treat the weeds.

You can help us fight the war against weeds by going to the Coalition of the Upper South Platte CUSP Weed Reporting Site and entering the weed name and location of sighting.
