Abstract: Through this presentation we will discuss what makes most earthworms invasive species in North America. We will start the discussion with European earthworms (Nightcrawlers are an example) and how they got here, what their impacts are and what we can do. We will then move to Asian earthworms (Jumping worms are an example) the latest invasive worm to arrive in the region. Found in garden beds, mulch and compost piles they represent a threat to the health of our managed and wild landscapes. We will learn how to identify the differences between the two groups and how you can participate in documenting them across the landscape.
