Endangered and Threatened Wildlife and Plants; 90-Day Finding on a Petition To List Usnea longissima in California as Threatened or Endangered

摘要

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to list Usnea longissima (a lichen) in California as threatened or endangered under the Endangered Species Act of 1973, as amended (Act). Based on our review and evaluation, we find that there is not substantial scientific or commercial information to demonstrate that the California populations of U. longissima are a discrete and listable entity under the Act. Therefore, we have determined that the petition does not provide substantial information to indicate that the petitioned action may be warranted, and we will not be initiating a further status review of this species in response to this petition. We ask the public to submit to us any new information that becomes available concerning the status of U. longissima or threats to it.
