Invasive exotic species are those species that are not native to our region, and in the absence of their natural predators and diseases, are able to thrive in their new environment. These species include buckthorn, dog-strangling vine, garlic mustard, sirex wood wasp, and emerald ash borer in our watershed, and they threaten the native flora through competition for space and resources. Invasive species can potentially cause physical damage and mortality, such as the cases with chestnut blight and Dutch elm disease.

SNC and our forestry partners are developing strategies to manage invasive exotic species within the watershed.

If you suspect that you have seen emerald ash borer or sirex wood wasp, contact the Ontario Ministry of Natural Resources at 1-800-667-1940.
