A fast invading plant threatens your favourite beach, fishing spot and wetlands in South Eastern Ontario

Not sure if you’ve ever seen Phragmites? It is a wetland perennial, that can grow up to 5 metres tall, and has a tassel on the top. It can spread over 3 metres per year and grows in extremely large, continuous clumps, eliminating habitat for native species and out competing natural vegetation along Ontario roads, wetlands, and on beaches.
The plant has spread by almost 30% between 2010 and 2017 with over 5000 hectares (around 6000 Canadian football fields) of strongly established colonies of the weed in the province. Virtually every region of Ontario has been impacted by the steady advance of this plant, which has been identified in Prince Edward County, Perth, Smith Falls, and Renfrew, and along the Ottawa and St Lawrence Rivers, with extensive concentration along the border of Hwy 401.
The impacts and cost of this invasion is not limited to the ecological and environmental damage to native species and even the species at risk it out competes. Last year in Ontario over 1 million dollars was spent to control the weed. It has also become a significant, and rapidly increasing budget item for many municipalities as control and eradication become a bigger expense.
We know what the problem is with Phragmites, but how to fight back? The good news is that organizations such as Ontario Phragmites Working Group (OPWG), the Ontario Invasive Plant Council (OIPC), Nature Conservancy of Canada, Ducks Unlimited Canada, Ministry of Natural Resources and Forestry, Georgian Bay Forever, Lambton Shores Phragmites Community Group, and numerous Municipalities, Conservation Authorities and Private Organizations are hard at work doing just that.
On their websites (www.opwg.ca) and (www.ontarioinvasiveplants.ca) you can find tips on identifying Phragmites, and steps to take to respond to new outbreaks since early eradication remains the first and best step to take. The Invading Species Awareness Program also has a web-based reporting tool to map invasive plants, find it here. It’s a simple action people can take, with a big impact. Smaller infestations can be managed by cutting but for significant infestations, herbicide control remains the only viable option.
