The U.S. Fish and Wildlife Service (Service) is initiating 5- year reviews of the Carolina northern flying squirrel (Glaucomys sabrinus coloratus), Cahow (Pterodroma cahow), boulder darter (Etheostoma wapiti), relict darter (Etheostoma chienense), Cumberland pigtoe (Pleurobema gibberum), rough pigtoe (Pleurobema plenum), orangefoot pimpleback (pearlymussel) (Plethobasus cooperianus), tan riffleshell (Epioblasma florentina walkeri), white wartyback (pearlymussel) (Plethobasus cicatricosus), noonday snail (Mesodon clarki nantahala), Nashville crayfish (Orconectes shoupi), Kentucky cave shrimp (Palaemonias ganteri), Cumberland sandwort (Arenaria cumberlandensis), Tennessee purple coneflower (Echinacea tennesseensis), large-flowered skullcap (Scutellaria montana), and rock gnome lichen (Gymnoderma lineare) under section 4(c)(2) of the Endangered Species Act of 1973, as amended (Act). The purpose of reviews conducted under this section of the Act is to ensure that the classification of species as threatened or endangered on the List of Endangered and Threatened Wildlife and Plants (50 CFR 17.11 and 17.12) is accurate. A 5-year review is an assessment of the best scientific and commercial data available at the time of the review.
