Invasive Species

An invasive species is a plant, animal, or microorganism introduced to an area outside of its normal range. These species spread in a natural environment not used to its presence. These non-native species can negatively impact native biodiversity, the economy, and society. A range of invasive species including fish, plants, invertebrates, fungus, and diseases can be found across the QC region.

Why Should We Control Them?

Invasive species pose a serious threat to Ontario's economy and natural environment. Non-native species provide little benefit to our local ecosystem. They lack natural controls, such as predators, pests, and disease. Invasive species have become one of the most pressing biodiversity issues. We recognize them as one of the greatest threats to biodiversity, second only to habitat loss.

What Can You Do?

Familiarize yourself with invasive species in our region. This will help you find them on your property.
Do regular checks for invasive species on your property. Watch for them on your walks.
Develop a plan to deal with invasive species on your property.
Share your knowledge with neighbours, as they may be affected by many of the same species.
Identify pathways of introduction and prevent new non-native species from establishing
- garden with native plants
- don't move firewood
- ensure contractor equipment is cleaned between sites, especially mowing equipment
- don't dump yard waste into natural areas
- never release aquarium or water plants into nature
Report invasive species and develop a plan to manage them. If you find invasive species in the wild, contact the Invading Species Hotline at 1-800-563-7711, or visit EDDMapS Ontario to report a sighting.
