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.

The treatment program for 2018 is now complete, and this map shows the areas we treated during that period. We will update the map with upcoming 2019 treatment areas when they become available in the spring of 2019.

Japanese Knotweed

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. 

Giant Hogweed

This plant is a public health concern. If touched, the sap causes skin blisters, long-lasting scars and can cause blindness if it gets in your eyes.
