Invasive Plants – why are they a problem?

Invasive plants are non-native plants that damage ecosystems and threaten local biodiversity. Invasive plants are a problem because they are able to outcompete native species, they spread aggressively, and once they are established they can be hard to completely remove.

Invasive species are now considered second only to habitat loss as the highest threat to biodiversity in our area. We urge gardeners to avoid planting these plants in their gardens because of the very high likelihood that they will escape and invade local natural spaces.

Below is a list of some common invasive plants that are especially problematic for our local ecosystems. For a more complete list of invasive species in our area, please visit Invasive Species Council of BC.
