Invasive Plant Management

Knotweed along King Road

Find out about our 2024 Invasive Work Parties and Drop Zones for the month of May.

An invasive plant is a non-native plant that has the potential to negatively impact the composition, structure and function of native ecosystems.

The spread of invasive plants has become a major concern for ecologists, naturalists, residents, and land managers across British Columbia. 

The City of Nanaimo is committed to preventing new invasive plants from becoming established in our parks and controlling invasive plants that pose a health concern for the public.

Partnering with a number of community volunteers, City Parks staff work to remove and manage priority invasive plants from a number of sites within our park system. Learn more about volunteering in your local park.
