List: Endangered or threatened species in Michigan

A look at Michigan’s endangered or threatened species.

The Federal Endangered Species Act of 1973 (Act) describes two categories of declining species of plants and animals that need the Act’s protections – endangered species and threatened species – and provides these definitions:

Endangered - any species that is in danger of extinction throughout all or a significant portion of its range;

Threatened - any species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.

Endangered species are at the brink of extinction now. Threatened species are likely to be at the brink in the near future.
