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.

Plants we treat

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. 

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. 

Where we treat invasive plants

Each summer, we treat specific areas across the District found to have significant invasive plant growth.

We will next be treating plants in the summer of 2023. A map of areas we plan to treat will be available on this page once those areas are identified.
