Proposed rule; reopening of comment period.
We, the U.S. Fish and Wildlife Service (Service), announce the reopening of the public comment period for the reinstated proposed rule to list the flat-tailed horned lizard (Phrynosoma mcallii) as a threatened species pursuant to the Endangered Species Act of 1973, as amended (Act). On November 17, 2005, the U.S. District Court for the District of Arizona vacated the January 3, 2003, withdrawal of the proposed rule to list the flat-tailed horned lizard, remanded the matter to us for further consideration in accordance with its August 30, 2005, and November 17, 2005, orders, and ordered us to make a new listing decision.
Pursuant to the Court's November 17, 2005, order, on remand we “need only address the matters on which the court's August 30, 2005, Order * * * found the January 3, 2003, Withdrawal unlawful, which may summarily be identified as whether the lizard's lost historical habitat renders the species in danger of extinction in a significant portion of its range.” To ensure our new final listing decision is based on the best scientific and commercial data currently available, we are reopening the public comment period on the 1993 proposed Start Printed Page 20638listing rule to solicit information and comment regarding the flat-tailed horned lizard's lost historical habitat.
We will accept comments from all interested parties until May 8, 2006. Comments received after the closing date may not be considered in the final decision on this action.

Previous Federal Actions
On November 29, 1993, we published a proposed rule to list the flat-tailed horned lizard as a threatened species pursuant to the Act (58 FR 62624). On July 15, 1997, we withdrew the 1993 proposed rule (62 FR 37852). Defenders of Wildlife and other groups challenged the 1997 withdrawal decision. On June 16, 1999, the District Court for the Southern District of California granted summary judgment in our favor upholding our decision not to list the flat-tailed horned lizard. However, on July 31, 2001, the Ninth Circuit Court of Appeals reversed the lower court's ruling and directed the District Court to remand the matter back to us for further consideration in accordance with the legal standards outlined in its opinion (Defenders of Wildlife v. Norton, 258 F.3d 1136). On October 24, 2001, the District Court for the Southern District of California remanded the 1997 withdrawal. Consistent with the District Court's remand order, we published a reinstatement of the 1993 proposed listing of the flat-tailed horned lizard as threatened and opened a 120-day comment period (66 FR 66384; December 26, 2001). The District Court further ordered us to commence a 12-month schedule for a final listing decision in compliance with the Ninth Circuit Court's order. As a result, we published a withdrawal of the proposed rule to list the flat-tailed horned lizard on January 3, 2003 (68 FR 331). The Tucson Herpetological Society, and other environmental organizations and individuals, challenged this withdrawal decision in the United States District Court for the District of Arizona.
On August 30, 2005, the District Court for the District of Arizona issued an order granting plaintiffs' motion for summary judgment “on the ground that the Secretary's withdrawal of the proposed rule violated the Endangered Species Act and the Ninth Circuit's remand order by failing to evaluate the lizard's lost habitat and whether that habitat was a significant portion of the range.” The Service's failure to make this specific determination was the only violation cited by the District Court. The court upheld all other aspects of the January 3, 2003, withdrawal decision. On November 17, 2005, the District Court issued a subsequent order, consistent with its August 30, 2005, order, vacating the 2003 withdrawal and remanding the matter to us for further consideration. The District Court reinstated the 1993 proposed rule to list the flat-tailed horned lizard as a threatened species for the duration of the remand, and ordered us to make a new listing decision by April 30, 2006, stating that, “on remand the agency need only address the matters on which the court's August 30, 2005, Order * * * found the January 3, 2003, Withdrawal unlawful, which may summarily be identified as whether the lizard's lost historical habitat renders the species in danger of extinction in a significant portion of its range.” The order indicates that, while the Court believes this determination is required by the Ninth Circuit's opinion, “the Secretary has wide discretion in delineating a significant portion of the lizard's range,” including in defining the “range” of the species (which the Court states must include some lost habitat) and in choosing the point in time at which to examine the range. On December 7, 2005, we published a document (70 FR 72776) reinstating the Start Printed Page 20639November 29, 1993, proposed rule to list the flat-tailed horned lizard as a threatened species. On March 2, 2006, we published a document announcing the reopening of a 14-day public comment period on the proposed rule to list the flat-tailed horned lizard under the Act (71 FR 10631). To ensure the public is provided with an adequate opportunity to comment on the matters identified by the Court, the parties filed a Joint Stipulation with the Court on March 28, 2006, to allow for an additional public comment period. On March 29, 2006, the Court granted our request for an extension of the April 30, 2006, deadline, and ordered us to submit the new final listing determination for the flat-tailed horned lizard to the Federal Register on or before the date six weeks after the close of this additional public comment period. For the reasons outlined in this document, we are now reopening the comment period on the proposed rule for an additional 16 days.

The flat-tailed horned lizard (Phrynosoma mcallii) is a small, cryptically colored, phrynosomatid lizard that reaches a maximum adult body length (excluding the tail) of approximately 87 millimeters (3.4 inches). The lizard has a flattened body, short tail, and dagger-like head spines like other horned lizards. It is distinguished from other horned lizards in its range by a dark vertebral stripe, two slender elongated occipital spines, and the absence of external ear openings. The dorsal surface of the flat-tailed horned lizard is pale gray to light rusty brown. The ventral side is white and unmarked, with the exception of a prominent umbilical scar.
The flat-tailed horned lizard is endemic (restricted) to the Sonoran Desert in southern California, Arizona, and northwestern Mexico. The species is documented in the Coachella Valley in Riverside County, California; the Imperial and Borrego Valleys in Imperial and eastern San Diego Counties, California; south of the Gila River and west of the Gila and Butler Mountains in Yuma County, Arizona; east of the Sierra de Juarez in the Laguna Salada and Yuha Basins in northeastern Baja California Norte, Mexico; and north and west of Bahia de San Jorge to the delta of the Colorado River in northwestern Sonora, Mexico (Grismer 2002; Rodriguez 2002). The flat-tailed horned lizard occurs at elevations up to 800 meters (2,600 feet) above sea level, but most populations are below 300 meters (980 feet) elevation. Various descriptions and estimates of the historical and current ranges of the flat-tailed horned lizard are described in the November 29, 2003, proposed rule (58 FR 62624); July 15, 1997, withdrawal of the 1993 proposed rule (62 FR 37822); and January 3, 2003, withdrawal of the 1993 proposed rule (68 FR 331).
In 2003, the Flat-tailed Horned Lizard Interagency Coordinating Committee released a revised version of the 1997 Flat-tailed Horned Lizard Rangewide Management Strategy (Flat-tailed Horned Lizard Interagency Coordinating Committee 2003). The 2003 Rangewide Management Strategy includes a map of the approximate historical and current range boundaries of the flat-tailed horned lizard. Using the geographic information system shape files used to develop the range map, we calculated the area of the historical and current ranges of the flat-tailed horned lizard in the United States and Mexico. Based on this information, we estimated the historical range (United States and Mexico) to be approximately 6,183,647 acres (2,502,433 hectares), which with the exclusion of the historic Lake Cahuilla would be reduced to approximately 4,874,238 ac (1,972,534 ha), and the current range (United States and Mexico) to be approximately 3,962,543 acres (1,603,884 hectares).
