Herbicide application for the control of Phragmites was completed on September 27, 2018 in the Long Point Crown Marsh.
The attached letter provides information regarding precautionary measures for residences using a surface water system. Updates on the implementation of the project will be posted on this website.
Project 2018 Summary
The Ministry of Natural Resources and Forestry (`the ministry`) has recognized invasive Phragmites australis as a significant threat to biodiversity and Species at Risk at Long Point and Rondeau coastal marshes. Using currently available management tools, the ministry has been working with several partners to eradicate invasive Phragmites from these locations.
The ministry is undertaking the third year of an Emergency Use Registration of herbicide to treat Phragmites in aquatic environments. Approval was obtained from the Pest Management Regulatory Agency, as well as permits and authorizations from Ministry of Environment, Conservation and Parks and Fisheries and Oceans Canada for the treatment of Phragmites in 2016 and 2017 and 2018 in the Long Point Region and Rondeau Provincial Park. Treatment in the Long Point Region uses a combination of aerial and ground application equipment. Application was approved for August 15 to October 31st, 2018.
The implementation of this pilot project at Rondeau and Long Point is based on the presence of significant natural values and the observed exponential growth of Phragmites in these coastal marshes. Local biologists and scientists have advised that the health of these coastal marshes is at a critical tipping point. If action is not taken to control Phragmites, the provincial, national and global significant values for which these areas are recognized will be lost. The attachments below provides a summary of the 2018 plans for implementation, communications, and monitoring.
Preliminary monitoring results are summarized in the presentation links below.
