Why are Invasive Species a Big Deal?
Invasive Species take over our Environment
Invasive species are among Canada’s greatest threats to the survival of our wild animal and plant life. These invaders arrive, often accidentally, from elsewhere in the world and, in the absence of natural predators, kill, crowd out or otherwise devastate native species and their ecosystems.
These nonnative plants and animals not only threaten to transform the wildlife, woodlands and waterways that Canadians depend on, they cost this country billions of dollars in losses to forestry, agriculture, fisheries and other industries affected by their impact.
