12-Month Finding on a Petition to List the Tucson Shovel-Nosed Snake (Chionactis occipitalis klauberi) as Threatened or Endangered with Critical Habitat

We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the Tucson shovel-nosed snake (Chionactis occipitalis klauberi) as threatened or endangered with critical habitat under the Endangered Species Act of 1973, as amended (Act). After review of the best scientific and commercial information available, we find that listing the Tucson shovel-nosed snake as threatened or endangered throughout its range is warranted. Currently, however, listing the Tucson shovel-nosed snake is precluded by higher priority actions to amend the Lists of Endangered and Threatened Wildlife and Plants. Upon publication of this 12-month petition finding, we will add the Tucson shovel-nosed snake to our candidate species list. We will develop a proposed rule to list the Tucson shovel-nosed snake as our priorities allow. We will make any determination on critical habitat during development of the proposed rule.
