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 that we are treating

Between May and September, 2018, we are treating two invasive plants using herbicides certified by both the provincial and federal governments:

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.
