Issuing agencies

Abstract

We, the U.S. Fish and Wildlife Service (Service), propose to list the Kentucky creekshell (Leaunio ortmanni [=Villosa ortmanni]), a freshwater mussel species from Kentucky and Tennessee, as an endangered species and designate critical habitat under the Endangered Species Act of 1973, as amended (Act). This determination also serves as our 12- month finding on a petition to list the Kentucky creekshell. After a review of the best available scientific and commercial information, we find that listing the species is warranted. Accordingly, we propose to list the Kentucky creekshell as an endangered species under the Act. Finalizing 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. We also propose to designate critical habitat for the Kentucky creekshell under the Act. In total, approximately 545 river miles (877 river kilometers) in Kentucky and Tennessee fall within the boundaries of the proposed critical habitat designation. We also announce the availability of an economic analysis of the proposed designation of critical habitat for the Kentucky creekshell.
