Invasive Species

Invasive species are plants and animals that have been introduced to an area without the predators and pathogens from their native habitats that would help keep them in check. They can threaten property and recreational values, infrastructure, agriculture, public health and safety, as well as the ecological health and diversity of our natural environment. Examples are; knotweed, giant hogweed, European fire ants, English ivy and European chafer beetles.


Invasive species are often difficult to control. Metro Vancouver works with experts across the region to develop locally-tested best practices for practitioners (e.g., municipal staff, contractors, landscapers, developers, stewardship groups and others) to manage a growing list of invasive species.



What are the invasive species of concern? The Invasive Species Council of British Columbia provides information to help you identify invasive species.

If you are a resident looking to dispose of invasive plants or soil containing invasive species, be aware that some facilities may not accept the material due to risk of further spread. Contact your municipality directly for control or disposal advice. DO NOT put invasive plants in your backyard composter as the temperature will not get hot enough to destroy the seeds.
