As one of the many threats to native ecosystems, invasive species are a large concern. They tend to displace the native plants that have evolved to grow in our local climate, and contribute to a lack of biodiversity.
Here is a list of the top invasive species to be on the lookout for in Marquette County:
Japanese Knotweed (Fallopia japonica)
Glossy Buckthorn (Frangula alnus)
Non-native Phragmites (Phragmites australis)
Garlic Mustard (Alliaria petiolata)
Spotted Knapweed (Centaurea stoebe)
Purple Loosestrife (Lythrum salicaria)
Eurasian Watermilfoil (Myriophyllum spicatum)
European Swamp Thistle (Cirsium palustre)
Butterbur (Petasites hybridus)
While this is not a complete list of our species of concern, these are some major species to be on the lookout for. If you have seen these, know of an area that has them growing, or want more information, there are a few steps to take:
1. Report any sighting to MISIN, a wonderful networking tool to share information on invasive species.
2. Call us! We have many tools and resources to share with you!
3. Be a mindful citizen. Make sure you are doing all you can to reduce the spread of invasive species!
Another great partner is the Lake to Lake Cooperative Invasive Species Management Area (L2L CISMA) More information on this particular CISMA can be found at:
