Invasive Species

How to manage invasive species

Invasive Species

Invasive species are not to be taken lightly! Invasive species can threaten biodiversity, increase soil erosion, and can even destroy infrastructure like concrete and asphalt.

Please do NOT dispose of any invasive plant by dumping trimmings or pulled plants in your yard, on City property, or elsewhere. Proper disposal is required to help prevent further spread.

What to do if you have invasive species on your property

KNOTWEED: The City of Terrace is partnered with the Northwest Invasive Plant Council to identify and manage knotweed. If you think you might have knotweed on your property, please let us know! Learn more here.


  • Put it in a plastic bag.
  • If you have just a little, put it in your curbside garbage cart (the black one). The goal is for it to be buried in the landfill in the bag.
  • You can also bring it to the transfer station.
  • Do NOT put it in your organics cart or yard waste bags.

What are some invasive plants to watch out for?

The Northwest Invasive Plant Council targets a variety of invasive plants for management. Some examples include:



The Invasive Species Council of BC
The Invasive Species Council of BC has information about the many other invasive species that have spread across our province. They also have a Plantwise app to help you choose non-invasive plants for your garden. Visit and their sister site

Northwest Invasive Plant Council
The Northwest Invasive Plant Council (NWIPC) formed as a committee in 1992, later becoming a not-for-profit organization in 2004. The NWIPC's goal is to prevent further damage to the ecosystems of the northwest and central B.C. from invasive alien plants. Visit
