Learn about management strategies for knotweed with local experts at our online talk.

Knotweed is a plant that is considered invasive and grows in disturbed natural areas as well as on private property. It is very difficult to remove as it has an extensive root system and can quickly regenerate. This forum explores management strategies for private property, as well as plans for management in Renfrew Ravine in a panel with local experts Tasha Murray from the Invasive Species Council of Metro Vancouver, Amy Hendel and Fiona Steele of Diamond Head Consulting and Krista Voth from the Vancouver Park Board. Full speaker bios will be listed below.
