Endangered and Threatened Wildlife and Plants; Four Species Not Warranted for Listing as Endangered or Threatened Species

We, the U.S. Fish and Wildlife Service (Service), announce findings that four species are not warranted for listing as endangered or threatened species under the Endangered Species Act of 1973, as amended (Act). After a thorough review of the best available scientific and commercial information, we find that it is not warranted at this time to list the Upper Missouri River DPS of Arctic grayling, Elk River crayfish, rattlesnake-master borer moth, and northern Virginia well amphipod. However, we ask the public to submit to us at any time any new information relevant to the status of any of the species mentioned above or their habitats.
