In December of 1991, 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. 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.
