The highly invasive jumping worm

This article was written by Mikayla Deiter

The Northside Community has many beautiful green spaces like Creek View Park, Webber Park, Shingle Creek, and our home, North Mississippi Regional Park. We are grateful that we can annually witness changes to the native flora and fauna of the upper Midwest, but there is an invader that is moving into Twin Cities. Amynthas agrestis, commonly known as the Asian Jumping Worm, looks harmless, but if left unaddressed could change our landscape forever. 

It’s easy to forget that worms shape our scenery. In the past, we might have been excited to find a worm in our garden or wriggling under a rock, but while worms might be great for compositing, they can take the essential nutrients away from established plants. According to the DNR, Jumping Worms are highly destructive to soils and woody plants. You can distinguish Jumping Worms from other species by these two main characteristics: no pigmentation, and when disturbed they react in a rapid and excited movement. In order to find the impact of Jumping Worms, researchers and conservation organizations are urging the public to engage in citizen science. 

At Carl W. Kroening Nature Center, we understand that we have a responsibility to preserve natural lands that we are entrusted with. In an effort to help identify Jumping Worm presence in the Twin Cities, Kroening Nature Center has partnered with University of Minnesota professor and Director of the Center for Forest Ecology, Lee Frelich, Ph.D. to host a number of BioBlitz events during September running through the middle of October. We encourage neighbors to help identify Jumping Worms in our community either at our park or on their own. All you will need is a garden trowel and a camera. If you believe you have found a Jumping worm, please submit data to https://tinyurl.com/27yf87u9. Kroening Nature Center is creating a Jumping Worm investigation kit for patrons to rent at our Adventure Hub free of charge. Just stop by the front desk. 

Kroening Nature Center is located at North Mississippi Regional Park off of I94 W. A part of the Minneapolis Parks and Recreation Board, we operate year-round and continually offer programming to all ages, groups and abilities. Because MPRB believes we can learn and live in nature with everyone, we acknowledge the Dakota and Ojibwa tribes’ land on which we reside.
