Endangered and Threatened Wildlife and Plants; Final Rule To Remove the Arizona Distinct Population Segment of the Cactus Ferruginous Pygmy-owl (Glaucidium brasilianum cactorum) From the Federal List of Endangered and Threatened Wildlife; Withdrawal of the Proposed Rule To Designate Critical Habitat; Removal of Federally Designated Critical Habitat

We, the Fish and Wildlife Service (Service), under the authority of the Endangered Species Act of 1973 (Act), as amended, have determined that it is appropriate to remove the Arizona distinct population segment (DPS) of the cactus ferruginous pygmy-owl (Glaucidium brasilianum cactorum) (pygmy-owl) from the Federal List of Endangered and Threatened Wildlife and, accordingly, also remove designated critical habitat for this DPS found in the Code of Federal Regulations (CFR) at 50 CFR 17.95. Additionally, we are withdrawing the proposed rule to designate new critical habitat for the Arizona DPS of the pygmy-owl (67 FR 7103, November 27, 2002). The Arizona DPS of the pygmy-owl was listed as endangered on March 10, 1997 (62 FR 10730), and critical habitat was designated on July 12, 1999 (64 FR 37419). On January 9, 2001, a coalition of plaintiffs filed a lawsuit with the District Court of Arizona challenging the validity of our listing of the pygmy-owl as a DPS and the designation of its critical habitat. After the District Court remanded the designation of critical habitat (National Association of Home Builders et al. v. Norton, Civ.-00-0903- PHX-SRB), we proposed a new critical habitat designation on November 27, 2002 (67 FR 7103). Ultimately, as a result of this lawsuit, the United States Court of Appeals for the Ninth Circuit issued an opinion on August 19, 2003, stating that "the FWS acted arbitrarily and capriciously in designating the Arizona pygmy-owl population as a DPS under the DPS Policy" (National Association of Homebuilders v. Norton, 340 F.3d 835, 852 (9th Cir. 2003)). In light of the Ninth Circuit's opinion, we have reassessed the application of the DPS significance criteria to the Arizona population of the pygmy-owl. Based on a review of the available information and science, the public comments received during the public comment period, and our DPS policy, we do not believe that the Arizona DPS of the pygmy-owl qualifies as an entity that can be listed
