Department of the Interior February 27, 2018 – Federal Register Recent Federal Regulation Documents

We, the U.S. Fish and Wildlife Service (Service), are removing Oenothera avita ssp. eurekensis, which is now recognized as Oenothera californica ssp. eurekensis (with a common name of Eureka Valley evening-primrose, Eureka evening-primrose, or Eureka Dunes evening- primrose) from the Federal List of Endangered and Threatened Plants. We are also reclassifying Swallenia alexandrae (with a common name of Eureka dune grass, Eureka dunegrass, or Eureka Valley dune grass) from an endangered to a threatened species. For Eureka Valley evening- primrose, this action is based on our evaluation of the best available scientific and commercial information, including comments received, which indicates that the threats have been eliminated or reduced to the point that the subspecies no longer meets the definition of an endangered species or a threatened species under the Endangered Species Act of 1973, as amended (Act). For Eureka dune grass, this reclassification is based on our evaluation of the best available scientific and commercial information, including comments received. We conclude that the stressors acting upon Eureka dune grass are of sufficient imminence, scope, or magnitude to indicate that they are continuing to result in impacts at either the population or rangewide scales, albeit to a lesser degree than at the time of listing, and we find that Eureka dune grass meets the statutory definition of a threatened species (i.e., the stressors impacting the species or its habitat are of sufficient magnitude, scope, or imminence to indicate that the species is likely to become an endangered species in the foreseeable future throughout all or a significant portion of its range).
