Invasive Species Network News

 

The Northwest Michigan Invasive Species Network works directly with over 40 partners in Benzie, Grand Traverse, Leelanau, and Manistee Counties. Our mission is to  protect, enhance, and promote northwest Michigan's natural communities through terrestrial invasive plant management and outreach.

With your help, we can help slow the spread of invasive terrestrial plant species that threaten northwest Michigan's beautiful natural areas. Thank you to those who granted ISN permission to treat invasive species on your property.

Below is a breakdown of species and the treatments that took place in the 2017 season.  

As always, please contact ISN if you have any questions regarding identification, treatment, or upcoming events. You can also report plant sightings to the  Midwest Invasive Species Information Network (MISIN).

JBJapanese Barberry

ISN hosted two programs focused on Japanese barberry this season; Japanese Barberry Dumpster Days and Japanese Barberry Buyback. Both events were a success! 

Japanese Barberry Dumpster Days
Two events were held; one in Grand Traverse County at the Grand Traverse Conservation District and one in Manistee County in collaboration with the Manistee Conservation District. Over 125 plants were collected during both events. 

Japanese Barberry Business Buyback
Thirteen businesses participated in this event which included removal of their Japanese barberry and replacement with native species. One-hundred-forty-four Japanese barberry were removed and replaced with natives. ISN was able to provide this service at no-cost to the participants with funds from the Great Lakes Restoration Initiative.

In addition to these events ISN also hosted workbees at six sites in Manistee County.

gbbGo Beyond Beauty

For many people, a garden's purpose begins and ends with beauty. However, we believe it is possible to create beautiful spaces that transcend beauty alone. Did you know that many of the plants that are most invasive in local natural areas originally arrived as ornamental garden plants? You can prevent the introduction and spread of invasives by purchasing plants at local nurseries and through landscapers that have committed to not selling high-threat invasive ornamental plants. Additionally, commit to not using invasives in your own landscape. Let's make Northwest Michigan an example of natural beauty, wildlife habitat, healthy waters, and bountiful gardens that inspires across the state of Michigan... and beyond!

We invite all nurseries, landscapers, businesses, organizations, and concerned landowners that are located in Benzie, Grand Traverse, Leelanau, and Manistee Counties to participate in Go Beyond 
Beauty.  Contact us or  visit our website for details.
