What are invasive species?

An invasive species is one that is not native and whose introduction causes harm, or is likely to cause harm to Michigan's economy, environment, or human health.

Many non-native species in Michigan, including fruits, vegetables, field crops, livestock and domestic animals, are important to our economy and lifestyle. Most non-native species are not harmful and may provide economic benefits. Invasive species cause harm when they out-compete native species by reproducing and spreading rapidly in areas where they have no natural predators and change the balance of the ecosystems we rely on.

Michigan's Invasive species

Below are just a few of the invasive species that threaten Michigan's lakes, rivers, forests and landscapes. View a list of invasive species that are a concern in Michigan, plus information on how to identify and report them. 

Spotted lanternfly with wings open

Spotted Lanternfly

The spotted lanternfly sucks sap from the stems and leaves of orchard trees, grape vines, oaks, pines and other host plants.

Didymo mats alter habitat and food sources for fish and can make recreation difficult or unpleasant.

Puckering of beech leaves caused by beech leaf disease

Beech leaf disease

After several years of infection beech leaf disease can kill beech trees. Michigan has about 37 million beech trees.

Branch with hemlock woolly adelgid

Hemlock woolly adelgid

These tiny insects secrete white wax as they feed on sap from hemlock shoots and branches which can result in tree death.

Michigan's prohibited and restricted species


In Michigan, some invasive species are legally designated as either "prohibited" or "restricted." If a species is prohibited or restricted, it is unlawful to possess, introduce, import, sell or offer that species for sale as a live organism, except under certain circumstances.
