Targeted invasive woody species include: Manitoba Maple (Acer negundo), European Buckthorn (Rhamnus cathartica), Burning Bush (Euonymus alatus), Japanese Barberry (Berberis thunbergia), Norway Maple (Acer platanoides), Scots Pines (Pinus sylvestris), non-native Honeysuckle (Lonicera sp.), Lilac (Syringa vulgaris), European Black Alder (Alnus glutinosa), Autumn Olive (Elaeagnus umbellate), Black Locust (Robinia pseudoacacia) and Multiflora Rose (Rosa multiflora).

This work will be completed under the Public Works exception to the Cosmetic Pesticide Ban under subsection 7.1(2)(4) of the Pesticides Act for the promotion of public health and safety. The following pesticide registered under the Pest Control Products Act (Canada) will be used: Garlon RTU Herbicide (Reg. #29334), containing the active ingredient Triclopyr, present as butoxyethyl ester.
