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.
The Noxious Weed Management Plan will be updated in the Fall of 2010.
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!
