- Invasive species are non-native plants and animals that become well established because they do not have any natural predators or controls.
- These introduced, non-native species spread quickly and have the ability to out compete native plant and animal species, impacting fragile ecosystems.
- Have been introduced to Canada either intentionally or accidentally. Human behaviour is the #1 contributor to the spread of invasive species
- Negatively impact biodiversity, species at risk, and water quality
Invasive species can be plants, animals, insects, or even fungi!
We call invasive species that live on land Terrestrial Invasive Species. Species that live in the wet areas near water are called Riparian Species. Aquatic Invasive Species or AIS, are invasive species that live or grow underwater.
How do invasive species spread?
On land, invasive species can be introduced and spread by:
- Seeds “hitchhiking” on people’s clothing, equipment pets or vehicles
- Invasive plants being intentionally or accidentally planted in gardens
- Improper disposal of garden waste
- Releasing pets into the wild
Aquatic invasive species are typically introduced and spread by:
- Improper disposal of aquarium water, plants and pets
- Planting invasive species near aquatic and riparian ecosystems
- Attached to boat motors, trailers and recreational gear
- Releasing aquarium pets into the wild
