Noxious Weeds: To keep, maintain or grow noxious weeds or other vegetation which creates a health or safety hazard to the public. Excluded from the provisions of this subsection are prairie plants, lands or portions of any lands located in a public nature area, and any property owned or leased by a unit of government. All noxious weeds are to be removed from property.
