Native earthworms from Canada were removed by the last glaciers and of the 19 species confirmed in Ontario, 17 originate from Europe and 2 from the United States. Since the retreat of the glaciers, the forested systems of Ontario have evolved without earthworms and their establishment in these areas significantly threatens the health of the forest lands.

What is it? Earthworms
Where did it come from? Europe and the United States.
Where is it found? In the soil throughout Ontario.
What does it do? They eat the leaf litter of forests, removing important nutrients for tree seedlings, ferns, and wildflowers.
What can you do? Never dump your bait bucket worms in a forest!
