Invasive Species

The State of Michigan defines an invasive species as a plant, animal, or disease that is not native and whose introduction causes harm, ​or is likely to cause harm to the economy, environment, or human health. Of the many invasive species that can be found in the Saginaw Bay area, a few are responsible for much of the damage caused to the Bay or are of special concern. 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 our priority species, click on the photos below. For more information about invasive species in general, check out these resources:
