The City of Toronto will be applying pesticide treatments in High Park starting August 10th. Urban Forestry staff will be using the applications to control the invasive herbaceous plant Dog Strangling Vine (Cynanchum rossicum). Urban Forestry Natural Resource worker crews have also been testing various manual control methods intended to supplement the use of chemical products in managing this aggressive species.
Treatment sites will rotate throughout the park during the control window from August to Early Sept, and signage will be posted at each site 24hours prior to treatment, then taken down 48 hours following completion as regulated by the Ministry of Environment, Conservation and Parks. Application is done by licensed City of Toronto staff. Information signage will be posted, along with the standard warning signage, to provide more information to park users.
