For the duration of the grant, partners used funds to control and remove over 5,000 acres (including 172 miles of Lake Michigan shoreline) of dense high-priority species. We hand-pulled the high-priority garlic mustard, because it can be controlled well using this method, but used herbicides on other invasives for best control. These species included bladder campion, kudzu, Japanese knotweed, oriental bittersweet, buckthorns, invasive phragmites, and reed canary grass. Treatment efforts were highly effective in controlling or eliminating these invasive plants. For example, invasive phragmites removal efforts reduced the population on Grand Traverse Bay by 78%, and we’ve now entered a “maintenance phase” where herbicide is used more sparingly.
This grant allowed ISN to generate a plethora of invasive species literature in the form of brochures, booklets, and other handouts. 2,350 copies of theInvasive Plant Field Guide were printed, and they were in such high demand that we ran out by year 2! Boat launch signs were created and installed at 10 sites throughout the region; at times these were accompanied by informative brochures or staffed by ISN partners to teach boaters more about boat cleaning. Informative displays were rotated through displays at parklands managed by ISN partner Grand Traverse Conservation District. An “alternatives brochure, “Plan Before You Plant,” was also published, helping people to choose native plants over invasive ornamentals.
One of the biggest outcomes of this grant is the Go Beyond Beauty program. After an immense amount of development and research, ISN launched this partnership with 8 area nurseries and 7 area landscapers to decrease the amount of invasive ornamental plants being sold and planted in northwest Michigan. All participants agreed not to sell high-priority invasive ornamentals and their cultivars, and many were able to offer a variety of Michigan-native plants to their customers.
Thank you for your support! We’re looking forward to what the future brings.
