Invasive weeds are troublesome weeds that may need to be controlled in pastures, rangelands, and wastelands.  These weeds may take over and crowd out native grasses and forbs, thus reducing the productivity of pastures and rangelands.  Some of these weeds may be injurious to man or livestock.  In wastelands they could be problematic for wildlife by destroying preferred food sources and habitat.  Invasive weeds are not on the state or county noxious weed list so control is voluntary but may be recommended. 

The following weeds are the most prevalent and problematic in Cass County.
