USFWS proposes to list the Alabama hickorynut (Obovaria unicolor) as an endangered species and the undescribed Obovaria cf. unicolor as a threatened species under the ESA. Both species are freshwater mussels. This document also serves as their 12-month finding on a petition to list the Alabama hickorynut. For Obovaria cf. unicolor, they also propose a rule issued under section 4(d) of the Act to provide for the conservation of the species. If this rule as proposed is finalized it would apply the protections of the Act to these species. They find that designation of critical habitat for both the Alabama hickorynut and Obovaria cf. unicolor is prudent but not determinable at this time. They will accept comments received or postmarked on or before 12 November 2024.
