List of threatened fauna of Michigan

The list of threatened fauna of Michigan includes almost 400 endangered, threatened and special concern species that are located in Michigan as a part of the fauna of the United States.^[1] Endangered and threatened species in Michigan are protected through the Endangered Species Act of the State of Michigan, part of the 1994 Michigan Natural Resources and Environmental Protection Act. The list was last updated in 2009 to its sixth iteration.^[2] At this time, 69 new species were added, including many species of freshwater mussels and snails, and 13 species were removed.^[1] The state also recognizes species of special concern, which are not protected under the act. These species have low or declining numbers in the state or a need for additional information on their populations in Michigan. If the species' numbers decline, they are moved to threatened or endangered status and afforded protection under the act; if they increase, they are removed from the list without further action.^[2]

Threatened and endangered species can also be listed under the federal Endangered Species Act, passed in 1973; the act covers over 1,250 plant and animal species. Species can be on either list or both lists – representation on one does not automatically determine representation (or status) on the other.^[1]^[3]

A large portion of the field surveys and research conducted with regards to threatened and endangered species in Michigan is undertaken by the Michigan Natural Features Inventory (MNFI) program. The MNFI program was originally developed in 1980 as part of the state natural heritage programs conceptualized by The Nature Conservancy (TNC), through which it received its first funding. The MNFI program severed relations with TNC in 2000, and became a program of the Michigan State University Extension Services.^[4]
