USFWS proposes to list the Long Valley speckled dace (Rhinichthys nevadensis caldera), a fish native to California, as an endangered species under the ESA. This determination also serves as our 12-month finding on a petition to list the Long Valley speckled dace. After a review of the best available scientific and commercial information, they find that listing the subspecies is warranted. Accordingly, they propose to list the Long Valley speckled dace as an endangered species under the Act. If finalize, this rule as proposed would add this subspecies to the List of Endangered and Threatened Wildlife and extend the Act's protections to the subspecies. Designation of critical habitat for the Long Valley speckled dace is not determinable at this time. They will accept comments received or postmarked on or before 7 October 2024.
