Ontario Expands Invasive Phragmites Projects 2025

New funding boosts provincewide invasive plant control

Ontario Phragmites Action (OPA) will support 87 new invasive Phragmites management projects in 2025 through the Invasive Phragmites Control Fund, backed by the Ontario Ministry of Natural Resources and coordinated by the Invasive Species Centre and the Nature Conservancy of Canada. 

Phragmites australis, also called the European common reed, is Ontario’s most harmful invasive plant. It spreads quickly through seeds and root fragments, forming dense stands that push out native plants and reduce biodiversity. It can be transported by wind, water, machinery, and human activity. 

“By investing in the management of invasive Phragmites, our government is taking decisive action to protect Ontario’s wetlands, roadways, and community spaces," said Mike Harris, Minister of Natural Resources. "With more than 80 projects underway across the province, we’re strengthening communities, preventing costly future impacts, and preserving our rich biodiversity.” 

Several rural counties will participate including the County of Perth, County of Wellington, and Norfolk County. 

The program empowers municipalities, conservation authorities, Indigenous communities, and non-profit groups to manage Phragmites. One major project is led by the Ausable Bayfield Conservation Authority, which will engage 15 partners across Huron County to control Phragmites along 1,700 km of roads, map 1,200 km for future treatment, and treat 12 new sites. A new cost-share fund under the Huron Clean Water Project will encourage wider participation. 

“Addressing this invasive species proactively helps avoid substantial costs, including reduced agricultural yields, obstructed public access to waterways, increased flooding, higher roadside maintenance expenses, and lost tourism revenue,” said Colin Cassin, Invasive Species Centre Executive Director. “This project, as well as the other projects funded by the Invasive Phragmites Control Fund, are one of Ontario’s greatest assets in overcoming the challenges posed by Phragmites.” 

Since 2019, the Control Fund has supported more than 131 projects. In 2025, funding will help organizations such as Birds Canada, Caldwell First Nation, and the City of St. Thomas. These partnerships ensure long-term protection of Ontario’s wetlands and community spaces.
