Invasive Plant Species
What’s an Invasive Plant? How do they get here?
Invasive weeds are typically non-native plants that have been introduced to British Columbia without the insect predators and plant pathogens that help keep them in check in their native habitats. For this reason and because of their aggressive growth, these alien plants can be highly destructive and difficult to control. The District of West Vancouver has many invasive weeds that are displacing natural habitat; some are even dangerous to human health. If left unchecked, they can smother or outcompete native plants, choking out food sources for local wildlife, and can lead to tree destruction or erosion.
What You Can Do:
Don’t dump. Disposing of decorative planters in the garden (or over your back fence) introduces these plants to our ecosystem. Please dispose of all your garden waste and hanging baskets—including soil, dead plants and clippings—either into compost or yard trimmings collection. (Exceptions are Knotweed and Giant Hogweed, these require special attention and care).
Keep it under control and choose plants wisely. If you have fast spreading invasives—like ivy or lamium—please keep them cut back and contained. Better yet, don’t plant these in your garden. Instead of “fast spreaders” or “vigorous self-seeders”, choose to plant non-invasive alternatives. For more information, please see this brochure from Metro Vancouver.
Help us control the spread. For removal of hogweed and knotweed, it is strongly recommended you hire a professional. For information on specific plant removal and proper disposal, please visit ipcmv.ca.
Japanese Knotweed on Municipal Lands
The District has contracted licensed applicators to use a technique called stem injection to control Japanese knotweed on Municipal Lands. This technique is a very controlled method of using herbicide by injecting it directly into the stem of the plant, and is the best known effective method to control this invasive and destructive plant. Download this informational brochure about Knotweed and Hogweed to keep on hand.
