Japanese Stiltgrass has been one of USACE’s Rend Lake’s largest woodland invaders. Rend Lake, located in southern Illinois works closely with the River to River Cooperative Weed Management Area Association on treatment strategies for the invasive species. During a recent National Public Lands Day event, volunteers removed a notable amount of Japanese Stiltgrass that was growing adjacent to nature trails. The species has a shallow root system which makes the plants easy to pull.
