Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for the Sickle Darter
We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for the sickle darter (Percina williamsi) under the Endangered Species Act of 1973 (Act), as amended. In total, approximately 104 river miles (168 river kilometers) in Bledsoe, Blount, Morgan, and Roane Counties, Tennessee, and Scott, Smyth, and Washington Counties, Virginia, fall within the boundaries of the proposed critical habitat designation. If we finalize this rule as proposed, it would extend the Act's protections to this species' critical habitat. We also announce the availability of a draft economic analysis of the proposed designation of critical habitat for the sickle darter.
Endangered and Threatened Wildlife and Plants; Lesser Prairie-Chicken; Threatened Status With Section 4(d) Rule for the Northern Distinct Population Segment and Endangered Status for the Southern Distinct Population Segment; Delay of Effective Date
We, the U.S. Fish and Wildlife Service (Service), are delaying the effective date of a final rule we published on November 25, 2022, and corrected on December 2, 2022, listing two distinct population segments (DPSs) of the lesser prairie-chicken (Tympanuchus pallidicinctus) under the Endangered Species Act of 1973, as amended (Act) and establishing measures that are necessary and advisable to provide for the conservation of the Northern DPS pursuant to section 4(d) of the Act. This delay is necessary for the Service to finalize conservation tools and guidance documents to avoid confusion and disruption with Federal agencies in the implementation of section 7 of the Act and to avoid disruption to the public who would be regulated by the rule.
