Terrestrial Invasive Plants
Terrestrial 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 forests resulting in economic, ecological or social disruption.
Terrestrial plants in a forest ecosystem can be a tree, shrub or herbaceous plant. These plants are introduced and spread by infested packaging material, seed dispersal by both environmental and human sources, or by escaping from gardens.
Terrestrial plants impact Ontario’s biodiversity, as well as our economy, agriculture, forestry, and outdoor recreational activities.
You can help prevent the spread of unwanted terrestrial plant species.
- Learn to identify terrestrial invasive plant species that are a threat to Ontario and how to effectively manage these species on your property. See The Landowners Guide to Controlling Invasive Woodland Plants
- Avoid using invasive plants in gardens and landscaping
- Buy native or non-invasive plants from reputable garden suppliers. Native plants provide habitat and food sources for native wildlife. 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
- When hiking, prevent the spread of invasive plants by staying on trails and keeping pets on a leash
- Report all sightings to the Invading Species Hotline 1-800-563-7711 or report a sighting online
