Join us in this citizen science project focused on documenting non-native Asian earthworms commonly referred to as the Jumping Worm. All the terrestrial earthworms in Minnesota are non-native, invasive species from Europe and Asia. We have no evidence that earthworms ever inhabited Minnesota before European settlement. Jumping worms are the latest invasive worm to arrive in Minnesota. They live in the top few inches soil and alter soil structure and chemistry through there feeding and burrowing behaviors. Found in garden beds, mulch and compost piles they represent a threat to the health of our managed and wild landscapes.

We are looking for Worm Rangers to help us investigate jumping worms distribution and dispersal mechanisms throughout Minnesota. Jumping worms are spread through composting, horticulture, landscaping and fishing bait. The overall goal of this project is to characterize the status of the jumping worm invasion in Minnesota. You will be trained to look at their distribution and dispersal. This training can be done remotely and self-guided or you can connect with project staff for a virtual in person training.

Exploring your yard and gardens is key! Visit our project website to learn more or join a workshop to learn more about them and how to collect data. If you suspect you have jumping worms take a photo. You can still participate this fall along with the 2021 growing season.
