Where we are controlling invasive plants

Under Provincial legislation, we are obligated to manage invasive species on our public lands. Because invasive plants cannot be completely eradicated by cutting or digging, treatment with herbicide is necessary.

Recognized world-wide as one of the worst invasive species, this plant grows and spreads very rapidly, will push out all native plants, damage creek-side ecosystems, and parks infrastructure. 

Where we are treating invasive plants in 2021

For 2021, we are treating only Japanese knotweed with chemicals (not giant hogweed). Select any yellow dot on the map to view the knotweed treatment dates and locations. We will continue to update this map over the summer as more locations are identified.
