Problem : Invasive exotic species (IES) are species that spread quickly after they are introduced into a new setting. They compete for resources, alter the food chain and threaten the habitats of local species. It becomes difficult, if not impossible, to eradicate them.
Education and awareness. The park conducts activities and produces IES awareness tools for various audiences. For instance, it suggests that residents inspect and clean their boats and trailers before moving to a new launch site. © Éco-Nature
Monitoring. The park monitors and identifies new IES along the river and tracks their spread. In addition to the species mentioned above, other IES (purple jewelweed and purple loosestrife) are found along the river. © Anais Boutin
Eradication. The park works to eradicate or control exotic species in natural settings, to help restore these habitats. © Anais Boutin
Planting. The park plants native species to replace lost ones (e.g., ash trees killed by ash borer infestations) and to prevent exotic species from gaining a foothold (common reed, Japanese knotweed, etc.). © Éco-Nature
Never plant an invasive exotic species, and don’t release your pets (turtles, fish, etc.) into the wild. If you spot an IES, take a picture and report it on the Sentinelle app or website.
