Michigan
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.
