Poison ivy is a native plant in Ontario and a persistent, ubiquitous resident in the McLean Reserve. It grows deep in the woods, out in the meadow, in dry as well as moist locations and is a food source for birds and animals. The Roads & Conservation Committee endeavors to control this plant in the vicinity of trails and to provide warning signage where the patches are large. However, since it is simply impossible to eradicate poison ivy from the entire 62 acre reserve, the importance of staying on the trails and learning to recognize this plant cannot be overemphasized.
A close encounter can lead to serious medical conditions. For more information check www.hikeontario.com/bulletin/factsheets/fact18.htm
