Notification of Aerial and Ground Herbicide Application for the Control of Invasive Phragmites within the Long Point Region


Environment and Climate Change Canada – Canadian Wildlife Service, the Nature Conservancy of Canada, the Ontario Ministry of Northern Development, Mines, Natural Resources and Forestry, and Ontario Parks will conduct annual management of invasive Phragmites in the Long Point Region. Phragmites plants in selected areas will be treated with an herbicide (RoundUp® Custom or Habitat Aqua) to control growth and limit spread.

Herbicide application will be completed in compliance with all regulations, and in appropriate weather conditions. Work will commence in remote areas of Long Point on August 15, 2021 and will be completed prior to October 31, 2021.

Implementation plans outlining the work to be conducted are provided below. The following locations will be treated:

Long Point and Big Creek National Wildlife Areas – scheduled to commence in September and be completed by mid-October, using aerial (helicopter) and ground application methods.

Long Point Crown Marsh, Long Point Provincial Park, private lands within the Big Creek Watershed and Lower Big Creek Wetland Complex, Turkey Point Provincial Park, and private lands within Turkey Point – scheduled to commence on August 18, 2021 using ground application methods.

PLEASE NOTE: There is NO RESTRICTION on the USE OF WATER for RECREATION OR DOMESTIC PURPOSES (i.e. toilets, showers, etc.) associated with this project. As a precautionary measure, during treatment dates, all residences using a surface water system for consumption (for example: taking water directly from the boating channel or inner Long Point Bay to drink, cook or for food preparation) should shut down their water system and avoid consumption of the water for a minimum of 48 hours following herbicide application. Systems should be flushed for at least 20 minutes before consuming again. Please note: these precautionary measures are only for private water systems drawing water from the channel or inner Long Point bay. If you get your water from the Port Rowan Municipal Water System, no action is required.

Bottled water will be available free of charge at the Big Creek National Wildlife Area office for those who require it. Residents or businesses in need of water may contact 647-232-8495 to make arrangements for pick up.

Project notification signage will be posted throughout the Long Point region. Updates, including the start and completion of herbicide application and the resumption of using surface water systems, will be available at, at the Environment and Climate Change Canada- Canadian Wildlife Service office at Big Creek National Wildlife Area and the Long Point Provincial Park office, or by contacting the Project Supervisors below.
