Invasive pale swallow-wort. Learn more about what invasive species are here.

Invasive species are species that are not native to Michigan and cause harm to Michigan’s economy, environment, or human health. These include species like zebra mussels and Asian carp, as well as lesser known species such as the fungus that causes oak wilt.

The Oakland County CISMA mainly works with invasive plant species, but has worked with other species like Red Swamp Crayfish and Oak Wilt. We are focused on managing the spread of eight priority invasive species including: non-native Phragmites (common reed), Black and Pale Swallow-worts, Knotweeds, European frog-bit, Flowering rush and Red swamp crayfish. However, OC CISMA members also have extensive experience managing other common invasive plants such as Buckthorns, Autumn olive, Garlic mustard, Asian bittersweet, and Purple loosestrife.

Identifying these species on public and private lands is key to controlling their spread. We can provide assistance in identification of many invasive species, as well as advice on management techniques. Please contact us if you have any questions!

To learn more about these species, use the menus and resources to learn how to identify, control and dispose of them. You can also find out how you can help prevent the spread and how to restore habitats with native species.
