From mid-August through October 2025, Technical and Stormwater Operations staff managed and removed invasive phragmites in select stormwater management ponds and roadside ditches across Barrie. Control methods included foliar spraying, a combination of foliar spraying and mechanical mowing, and selective cutting/removal in water. This work is done each year to improve pond function, restore native vegetation, and protect our local ecosystem.
Invasive Phragmites (European Common Reed) cause damage to Ontario's biodiversity, wetlands and beaches. The perennial grass was transported to North America from its native home in Eurasia. The aggressive plant spreads quickly and out-competes native species for water and nutrients. Learn more about phragmites and other invasive plants.
