News Haliburton County versus Invasive Weeds SHARE ON: Kaitlin Livingston, contributor, Thursday, Oct. 27th, 2016 The Haliburton County Roads Committee wants to treat the invasive weeds in the community. Director of Public Works Craig Douglas says poison ivy, japanese knotweed and phragmites are the major toxic plants found in the area. Douglas says he will be working with the County Weed Inspector to control the spread of these weeds. He says one of the things they will do is roadside mowing in the spring and early summer. Douglas says highway rights-of-way are a major pathway for invasive plants. The County of Haliburton is committed to controlling the spread of these weeds, and reducing future infestations.
