Reclassification of the Endangered June Sucker to Threatened With a Section 4(d) Rule; Final Rule

We, the U.S. Fish and Wildlife Service (Service), are reclassifying the June sucker (Chasmistes liorus) from endangered to threatened under the Endangered Species Act of 1973, as amended (Act), due to substantial improvements in the species' overall status since its original listing as endangered in 1986. This action is based on a thorough review of the best scientific and commercial data available, which indicates that the June sucker no longer meets the definition of an endangered species under the Act. The June sucker will remain protected as a threatened species under the Act. We are also finalizing a rule under section 4(d) of the Act that provides for the conservation of the June sucker.
