Invasive Species

What is an 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. They compete with native species for resources, reproduce / spread quickly, and lack natural predators. Invasive species affect the stability of Michigan ecosystems and threaten the survival of Michigan's native species.
