Weed Management

Douglas County Noxious Weed Plan and Enforcement Resolution

A major component of the Undesirable Plant Management Plan is the requirement to provide Douglas County Property Owners with technical assistance in determining methods to control or eliminate their weed problems. We have worked very hard over the past 14 years to insure County owned properties are under treatment for weeds and are continuing that endeavor.  We have worked with other public entities to assist them in their weed control problems. At the same time, we offered technical assistance to private property owners to control noxious weeds on their land be it several hundred acres or an individual lot.

Prevention, eradication and control are three general weed management strategies.
The cheapest weed to control is one you don’t have yet!  Like a small fire, a small patch treated now will prevent a major problem tomorrow!  Be a good neighbor and control your noxious weeds!

What We Do

  • Develop and administer the Douglas County Noxious Weed Management Program including application of herbicides, mowing activities in County right-of-ways and County open space.
  • Provide weed management education to Douglas County citizens.
  • In conjunction with Tri-County Health Department, administer the Douglas County mosquito mitigation program through trapping for adult mosquitoes and larviciding immature mosquitoes in standing water bodies in Douglas County maintained properties and culverts.
