Invasive species are any kind of living thing that is not native to New Brunswick that displaces, kills, or outcompetes native species for space and resources. Invasive species can be a serious threat to native populations and the structure and function of natural ecosystems. Invasive species can also have negative impacts on human health, recreational activities, and the economy.

Examples of invasive species that have a large impact on New Brunswick’s biodiversity include those which cause Dutch Elm Disease, Beech Bark Disease, and White-nose Syndrome (decimating some bat populations).

There are several invasive species that now occur in the province and are poised to become significant threats to New Brunswick’s biodiversity. Some examples are:

  • Emerald Ash Borer
  • Eurasian Water-milfoil
  • Smallmouth Bass
  • Green Crab
  • Gypsy Moth
  • Brown-tail Moth
  • Glossy Buckthorn

Most invasive species are spread through human activities, but usually not intentionally. Being aware of invasive species and the steps you can take to prevent moving them into, and around, New Brunswick is something every New Brunswicker can do. Some examples of ongoing campaigns to limit the spread and impact of invasive species include the following:

The Department of Natural Resources and Energy Development (DNRED) supports efforts to monitor and manage the impacts of invasive species through collaboration with the New Brunswick Invasive Species Council and a variety of other government and non-government stakeholders.
