USFWS proposes to list the Cedar Key mole skink (Plestiodon egregius insularis), a lizard subspecies from the Cedar Keys, Florida, as an endangered species under the ESA. After a review of the best available scientific and commercial information, they find that listing this subspecies is warranted. They also propose to designate critical habitat for the Cedar Key mole skink under the Act. In total, approximately 2,713 acres (1,098 hectares) in Levy County, Cedar Keys, Florida, fall within the boundaries of the proposed critical habitat designation. In addition, they announce the availability of an economic analysis of the proposed designation of critical habitat for the Cedar Key mole skink. If finalized, this rule as proposed would extend the Act's protections to this subspecies and its designated critical habitat. They will accept comments received or postmarked on or before 7 October 2024. POC is Lourdes Mena, email: lourdes_mena@fws.gov; tele: 352-749-2462.
