90-Day Finding on a Petition To Remove the Uinta Basin Hookless Cactus From the List of Endangered and Threatened Plants; 90-Day Finding on a Petition To List the Pariette Cactus as Threatened or Endangered

We, the U.S. Fish and Wildlife Service (Service), announce two 90-day findings made under the Endangered Species Act of 1973, as amended (Act). One finding concerns a petition to remove Uinta Basin hookless cactus (Sclerocactus glaucus) from the List of Endangered and Threatened Plants, and the other a petition to list Pariette cactus (Sclerocactus brevispinus) as a threatened or endangered plant. Until recently, these species were considered one taxonomic entity, so the petitions are being considered concurrently in this notice. We find the petition to remove Sclerocactus glaucus from the List of Endangered and Threatened Plants does not present substantial information indicating that the petitioned action may be warranted, and we are not initiating a further status review in response to this petition. However, in order to determine the appropriate status of S. glaucus given recent taxonomic revisions to this species, we are initiating a 5-year review under section 4(c)(2)(A) of the Act. Through this action, we encourage all interested parties to provide us information regarding the status of, and any potential threats to, this species as it was originally listed (i.e., information pertaining to S. glaucus, S. brevispinus, and S. wetlandicus). We find the petition to list Sclerocactus brevispinus presents substantial information indicating that the petitioned action may be warranted, and we are initiating a further status review in response to this petition. Through this action, we encourage all interested parties to provide us information regarding the status of, and any potential threats to, this species.
