Invasive Alien Species

Invasive Alien Species (IAS) are plants, animals and micro-organisms that spread beyond their natural range into new locations. They have the potential to cause extensive economic hardship and environmental damage. Examples of IAS include purple loosestrife, zebra mussel, Brown Spruce Long-horned Beetle, and Asian long-horned beetle.

IAS may be introduced by human activity (international trade, travel, migration), or by natural means such as flight or wind. IAS do not respect political boundaries. They can originate from other continents, neighbouring countries, or different ecosystems within Canada.

Preventing and managing invasive species will strengthen Canada’s long-term competitiveness, protect its natural environment, and contribute to the well-being of its citizens.
