Noxious Weeds

Noxious Weed Law

Since 1990 there have been state regulations enforcing the control of noxious weeds in Colorado. Recent revisions to the Colorado Noxious Weed Act have enabled county and municipal governments to implement additional enforcement measures to reclaim infested acres and protect weed-free land. 

In January of 2020 Routt County added Common mullein (Verbascum thapsus) and Curly dock (Rumex crispus) to the county's noxious weed list, creating a total of 15 noxious weeds whose management is required in order to prevent their spread and protect our native ecosystems.
