Stop the Spread

Every year non-indigenous species are introduced to Ontario’s waters and forests through a variety of pathways, such as aquarium and horticultural trades, live food fish trades, packaging material, movement of wood, and unauthorized fish introduction’s and/or transfers. These invaders have profound ecological, economic, and recreational impacts on both the aquatic and terrestrial ecosystems.

Terrestrial invasive species have caused a significant threat to Ontario’s biodiversity, economy and outdoor recreation. With rapid growth and few natural controls, invasive plants are able to outcompete and seriously damage native habitats.

More than 185 non-indigenous species have invaded the Great Lakes. While they often first appear in the Great lakes, exotic species can disperse, sometimes very rapidly into inland waters, posing a serious threat to native species and their habitats.

Unfortunately, once established, these invasive species can be impossible to eliminate. The active participation of the public, boaters, anglers, campers, hikers, and other recreationalists, is vital to prevent the spread of these invaders.
