Plants & Insects

An invasive species is any non-native organism that causes economic or environmental harm. When a plant introduced to a new environment where it does not have natural predators to keep it in check, it can quickly overtake native populations.

Most invasive species are unintentionally introduced by human activities. That’s why each of us has a part to play in preventing and controlling their spread.

Invasive Plants

Invasive plants are non-native plants that have been introduced to British Columbia where we lack the insect predators and plant pathogens that help keep them in check in their native habitats. They are the second greatest threat to global biodiversity, after habitat destruction.
