Minnesota has populations of Bohemian knotweed (Fallopia x. bohemicum) and Japanese knotweed (Fallopia japonica) which were introduced as ornamental plantings. Duluth has over 400 known knotweed locations, yet it is not as prevalent elsewhere in the state. Knotweed patches exist in a wide variety of locations, from manicured green spaces to forested areas. Knotweeds have spread to natural areas replacing native plants, causing erosion, and blocking waterways, yet most patches are well under 1 acre. Plant characteristics and other combined factors make knotweed management a complicated task requiring coordination among many groups while integrating the latest research findings from the University of Minnesota and elsewhere. This presentation will give an overview of the successes, failures, and challenges ahead as the Duluth CISMA strives to protect our water-rich environment along the shores of Lake Superior from this tenacious plant.
