Abstract:

The U.S. Fish and Wildlife Service (Service) announces a 12-month finding on a petition to remove the Bliss Rapids snail (Taylorconcha serpenticola) from the Federal List of Endangered and Threatened Wildlife (List) pursuant to the Endangered Species Act of 1973, as amended (Act) (16 U.S.C. 1531 et seq.). Based on a thorough review of the best scientific and commercial data available, the Service finds that the species continues to be restricted to a small geographic area in the middle-Snake River, Idaho, where it is dependent upon cool-water spring outflows. Although some threats identified at the time of listing in 1992 no longer exist or have been moderated, ground water depletion and impaired water quality still threaten the Bliss Rapids snail. In addition, there are significant uncertainties about the effects of hydropower operations and New Zealand mudsnails on the persistence of Bliss Rapids snails in riverine habitats. In the absence of the Act’s protections, existing regulations are not likely to be sufficient to conserve the species. Given the Service's current understanding of the species’ geographic distribution, habitat requirements, and threats, the species continues to meet the definition of a threatened species under the Act. Therefore, the Service has determined that removing the Bliss Rapids snail from the List is not warranted at this time.
