"Non-native earthworms in Canada: Entering the second wave of invasion" Webinar Handout
This is a handout from our webinar, "Non-native earthworms in Canada: Entering the second wave of invasion". Non-native earthworms are highly influential ecosystem engineers that fundamentally change the habitats they invade. They are a major challenge to conservation and restoration as there are currently no practical, large-scale options to control them. The invasion of non-native earthworms in Canada is a recent phenomenon, with the second wave of invasion being led by species from Asia. The handout provides information on the signs of an invasion and what can be done to control the spread of non-native earthworms.
"Non-native earthworms: Entering the second wave of invasion" webinar with Dr. Michael McTavish
Most of the earthworms that we have in Canada are relatively recent arrivals – European species have been arriving since the earliest days of overseas colonization and we are now entering a second wave of invasion by species from Asia. Non-native earthworms are highly influential ecosystem engineers that fundamentally change the habitats that they invade. With no practical means of control, it is important to understand how earthworms spread, what they change when they arrive, and how we can learn to manage and live with these new invaded ecosystems.
