Noxious weeds are aggressive plants that are not native to our area. Most have come from Europe or Asia either accidentally or as ornamentals that have escaped. These plants have an advantage because the insects, diseases, and animals that would normally control them are not found here. Because these plants have developed specialized mechanisms to survive, they are able to spread at an alarming rate.
The Douglas County Board of County Commissioners adopted an Undesirable Plant Management Plan in accordance with the requirements of Colorado state law, Colorado Noxious Weed Act, §35-5.5-101-119, C.R.S. The County provides a complete listing of identified noxious weeds in the Undesirable Plant Management Plan.
Douglas County utilizes integrated weed management techniques to combat noxious weeds on County Roads and Open Space. . These techniques include biological control, hand pulling, revegetation to include use of competing grass seed mixes and herbicides. The County program places strong emphasis on education. As part of our ongoing effort, the County provides informational flyers detailing biology and control measures for many of the noxious weeds on the undesirable plant management plan.
Noxious Weeds and Our Natural Areas
Noxious weeds are moving into our valued ecosystems and displacing our native plants at an alarming rate. When the plants that wildlife uses for food, shelter, or nesting are gone, the wildlife leave the area.
Noxious Weeds and Our Agricultural Lands
Noxious weeds also impact our valuable agricultural lands and commodities. When resources are not available for their desired use, it takes more land to raise the same number of cattle or bushels of wheat. Learn what grass seed mixes compete with Noxious Weeds and how to set up and Individual Weed Management Plan (IWMP). Because of these factors, they have been declared by state, local, and federal governments to be undesirable, and their control, containment, and eradication are required by law. In Douglas County the following weed priorities have been made for eradication:
- A-list weeds to be eradicated
- B-list weeds to be eradicated
- B-list weeds to be contained or monitored and suppressed
