Colorado is seeing a dramatic increase in noxious weeds. These invasive non-native plants have been introduced by accident or as ornamental plants and are devastating thousands of acres of wildlife habitat and natural areas. Left uncontrolled, noxious weeds will form dense mono-cultures and displace native and desirable plants. Native plant loss affects wildlife that depends on the native vegetation for survival.
Jefferson County's Invasive Species Management Department works to educate landowners about the affects of noxious weeds and how to manage these unwelcome plants.
Everyone is responsible for controlling noxious weeds on their property. Specific control techniques must be used on each plant species; what works to control one weed might not work on another.
The Colorado Noxious Weed Act and Regulations requires public and private landowners to manage noxious weeds on their property. Under the Act, a prioritized list has been established, demanding a higher level of control for some weeds, including eradication and containment.
Eradication means the complete elimination of a noxious weed. Eradication occurs when weeds are prevented from forming seeds or developing reproductive components.
Containment means controlling noxious weeds and preventing them from spreading to areas where they are not known to grow.
Suppression means managing a specific noxious weed by reducing its population and preventing it from spreading onto neighboring properties.
