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.
