Long Point Crown Marsh Phragmites Control Program – Project Update

Long Point Phragmites Control Program


Herbicide application for the control of Phragmites was initiated on September 5th in the Long Point Crown Marsh.

Updates on the implementation of the project will be posted on this website.

2019 Project 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 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 fourth 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 the Long Point Region and Rondeau Provincial Park.  Treatment in the Long Point Region will use a variety of ground application equipment.  Application was approved for August 15 to October 31st, 2019.

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. The attachments below provide a summary of the 2019 plans for implementation and monitoring.
