The treatment area is marked with signs at every entry point around its edge. Information signage will be posted by city staff, along with the standard warning signage, to provide more information to Arboretum users. Warning signage is posted 24 hours before treatment, and is removed 48 hours following treatment, according to Ministry of the Environment and Climate Change guidelines.
Legislation: The Cosmetic Pesticide Ban, Regulation 63/09 under the Pesticides Act, allows some exceptions for non-cosmetic use of pesticides including a forestry exemption. The use of pesticides in forestry is essential to protect trees from competing vegetation in the maintenance or establishment of a forest.
