City and Partners to Treat Invasive Knotweed in September

[Duluth, MN] The City of Duluth and the Duluth Collaborative Invasive Species Management Area (CISMA) will be herbicide treating over 30 invasive knotweed* patches on public land contributing to the collective efforts to help control this aggressive plant.  Prairie Restoration has been contracted to apply treatments between Tuesday, September 3, and Friday, September 13, 2019. Signs will be posted at each site for up to 1 week after each treatment concludes. 

Trail re-routes at 4 locations will be necessary for 48-hours after herbicide treatment.  Snow fencing will be placed across paths, and detour signage will be posted at the following areas:

•    Chester Rim hiking/biking trail

•    Kingsbury Creek hiking/biking trail above the Lake Superior Zoo

•    Superior Hiking Trail section (North 24th Ave West to Twin Ponds) will be re-routed at Forgotten Park

•    The Lakewalk in Lakeside near Super One (5928 E Superior St.)

For your safety, please keep yourself, kids, and pets away from contacting the knotweed plants where you see these signs. 

This work is supported by a MN Department of Agriculture noxious weed grant.

*Japanese and Bohemian knotweed, two invasive plants, multiply by seed, stem fragment, and underground stems.  This plant causes extreme damage to properties, river corridors, and green space.  Since mowing, cutting, and digging can spread the plant further, knotweed must be treated in the fall to control it.
