A new soil invader is reshaping ecosystems across the Midwest, and communities in Illinois are beginning to feel the impact. Jumping worms (Amynthas spp.) (a rapidly spreading group of invasive earthworms) are now established in parts of the state, raising concerns for gardeners, land managers, and conservationists alike. Unlike familiar European earthworms, jumping worms dramatically alter soil structure, nutrient cycling, and plant communities, creating cascading ecological effects.
This educational program offers a comprehensive look at what we know so far. Attendees will learn how to identify jumping worms at different life stages, understand their biology and behavior, and explore the latest research on their ecological impacts. The session will also highlight emerging strategies for monitoring, early detection, and management—tools that can help homeowners, natural areas stewards, and community members respond effectively to this fast-moving invader.
The evening’s speaker, Tricia Bethke, Forest Pest Outreach Coordinator at The Morton Arboretum, brings extensive experience in invasive species education and forest health. She will share current findings from regional research efforts and provide practical guidance for recognizing and reporting jumping worm activity.
Whether you’re a gardener, naturalist, land manager, or simply curious about local environmental issues, this program offers an accessible and timely introduction to one of Illinois’ newest ecological challenges.
