Invasive species are introduced to new areas by humans, often without our realizing it.
Worldwide travel has increased over recent years, and the goods we use travel long distances by land, sea, and air as well. These movements can result in the introduction of invasive species. Once invasive species arrive, they can quickly move into new areas via people, animals, wind, water, and other means of natural dispersal. For invasive plants, disturbance of native vegetation and soil further increases the risk of them becoming established and spreading.
As a government staff member or a person working on provincial public lands under an agreement with the Province, you need be aware that invasive species often hitch rides on equipment and materials that people transport from place to place. There can be hitchhikers on our boats, boots, supplies, vehicles, and animals—an invasive animal can get caught up in your supplies, a tiny seed from an invasive plant may attach to your boot, or a microscopic invasive species living in the water may be left in your boat.
