Aquatic Invasive Plants
Aquatic invasive plants are plants that have been moved from their native habitat to an introduced area where they are able to reproduce quickly and crowd out native species. These plants impact our waterbodies resulting in economic, ecological or social disruption.
Aquatic plants are found in and around waterbodies. These plants can be free floating or floating and rooted in sediment, rooted and submergent (underwater) or emergent (partly under water and partly above the waters surface). Aquatic plants are introduced and continue to spread by shipping vessels, recreational and commercial boating and the aquarium and water garden trade.
Aquatic plants impact our wetlands and waterways in a variety of ways. Different species affect recreational activities, such as boating, fishing and swimming, displace native vegetation, slow down water flow and alter oxygen levels.
You can help prevent the spread of unwanted aquatic plant species.
- Learn to identify aquatic invasive plant species that are a threat to Ontario
- Inspect your boat, trailer, and equipment after each use. Remove all plants, animals, and mud before moving to a new waterbody
- Buy native or non-invasive plants from reputable garden suppliers. See Grow Me Instead: Beautiful Non-Invasive Plants for Your Garden
- Dispose of invasive plants in the garbage. Do not put them in the compost or discard them in natural areas. Discarded flowers may produce seeds, and seeds may sprout.
- Report all sightings to the Invading Species Hotline 1-800-563-7711 or report a sighting online
