Japanese Knotwood demonstration
Fairfax Park, Eau Claire
Although plants create a beautiful landscape and provide homes and food for a variety of critters, some plants are real terrorists to their environment. Japanese Knotweed is an example of such a threat. The Eau Claire City Parks and Recreation Department and the West Central Wisconsin Invasive Plant Management group are holding a public demonstration about Japanese Knotweed at 2:00 on July 16th in Fairfax Park. Japanese Knotweed is an invasive exotic perennial that rapidly and aggressively takes over an area. Knotweed rhizomes can reach 60 feet or more from parent plants and give rise to new stalks which can grow through building foundations and roadways. Because it has an attractive flower and the stem looks similar to bamboo, it has been planted as an ornamental in some yards. There is a patch of Japanese Knotweed in Fairfax Park that was probably accidentally brought to the site through added fill.
Both the City Parks Department and the WCWIPMA want citizens to recognize Japanese Knotweed, avoid transporting it from one spot to another, and learn how to eradicate it. The July 16th demonstration will include a presentation by John Sippl, Natural Resources Conservation Service Conservationist, about plant identification and control techniques. All citizens are welcome to come for the demonstration that will be held at Fairfax Park in the field north of the Fairfax Swimming Pool. Citizens can also volunteer that afternoon to help cut down the Knotweed, loppers and gloves will be available for their use. City employees will subsequently dispose of the plants and spray the cut stems to help eradication.
If you are interested in volunteering for the eradication effort on July 16th, please contact either Roberta Kostka, 715-839-8285 or John Sippl, 715-832-6547, ext 130. You are welcome to come to the demonstration even if you’d prefer not to cut plants as this would be a good opportunity to ask staff with the West Central Wisconsin Invasive Plant Management group your invasive plant identification and control questions.
