The U.S. Fish and Wildlife Service (Service), propose to list the Barrens darter (Etheostoma forbesi), a fish species from Cannon, Coffee, Grundy, and Warren Counties, Tennessee, as an endangered species under the Endangered Species Act of 1973, as amended (Act). This determination also serves as the 12-month finding on a petition to list the Barrens darter. After a review of the best scientific and commercial data available, they find that listing the species is warranted. If finalized, this rule as proposed would add this species to the List of Endangered and Threatened Wildlife and extend the Act's protections to the species. Designating critical habitat for this species is not determinable at this time. Comments must be received or postmarked on or before 2 September 2025.
