Invasive Species

The state of Michigan defines an invasive species as one that is not native and whose introduction causes harm, ​or is likely to cause harm to Michigan's economy, environment, or human health. There are many types of invasive species in Saginaw Bay, including plants, animals, insects and even diseases. A few specific species are responsible for much of the damage caused to the bay. SB-CISMA has classified invasive species concerns in the Saginaw Bay based on their capacity for damage to environment, economy, and human health. For more information on priority species, click on the photos below or go to www.michigan.gov/invasives. Have you seen an invasive species in the wild? Visit misin.msu.edu to report infestations.
