Withdrawal of the Proposed Rule To List the Flat-Tailed Horned Lizard as Threatened

We, the Fish and Wildlife Service (Service), have determined that the proposed listing of the flat-tailed horned lizard (Phrynosoma mcallii) as a threatened species under the Endangered Species Act (Act) of 1973, as amended, is not warranted and, thus, we withdraw our November 29, 1993, proposed rule (58 FR 62625). As stated in our January 3, 2003, withdrawal of the proposed rule to list the species as threatened (68 FR 331), we have made this determination because threats to the species as identified in the November 29, 1993, proposed rule are not significant, and available data do not indicate that the threats to the species and its habitat, as analyzed under the five listing factors described in section 4(a)(1) of the Act, are likely to endanger the species in the foreseeable future throughout all or a significant portion of its range. The analyses and conclusions contained in the January 3, 2003, withdrawal (68 FR 331) are incorporated herein by reference subject to the revisions contained in this notice. In this revised withdrawal, we have re-examined the lost historical habitat of the flat-tailed horned lizard in relation to our January 3, 2003, withdrawal of the proposed listing rule and have determined that the lost historical habitat is not a significant portion of the flat-tailed horned lizard's range and does not result in the species likely becoming endangered in the foreseeable future throughout all or a significant portion of its range.
