Invasive Species Network
The Northwest Michigan Invasive Species Network (ISN) was founded through the merger of the Grand Traverse Regional Invasive Species Network and the Northwest Michigan Cooperative Weed Management Area (CWMA) in 2012. ISN works directly with over 40 partners in Benzie, Grand Traverse, Leelanau, and Manistee Counties to manage populations of invasive species that threaten northwest Michigan’s high-quality natural areas. It is currently funded through grants from the Great Lakes Restoration Initiative (GLRI), the US Forest Service (USFS), and the Michigan Invasive Species Grant Program (MISGP).

So Much Information, Where Do I Start?
If you have something on your property that you think is invasive, we can point you in the right direction. The websites and materials below will help you identify mysterious plants, insects, tree diseases, critters, etc. and help determine if it is or will become invasive. 
​
What Is an Invasive Species?
1.    Non-native (or alien) to the ecosystem under consideration and
2.   whose introduction causes or is likely to cause economic or            environmental harm or harm to human health.
3.   Plants, animals, insects and even tiny microbes can be considered  invasive.

Why should we be concerned about Invasive Species?
Invasive species threaten the biodiversity and health of the ecosystems they invade. They negatively impact ecosystems because they displace native species, reduce native wildlife habitat, reduce forest health and productivity, alter ecosystem processes, and degrade recreation areas.
