Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for the Cactus Ferruginous Pygmy-owl (Glaucidium brasilianum cactorum)

We, the U.S. Fish and Wildlife Service (Service), designate critical habitat pursuant to the Endangered Species Act of 1973, as amended (Act), for the cactus ferruginous pygmy-owl (Glaucidium brasilianum cactorum). A total of approximately 296,240 hectares (731,712 acres) of riverine riparian and upland habitat are designated. Critical habitat is located in Pima, Cochise, Pinal, and Maricopa counties, Arizona. Section 7 of the Act prohibits destruction or adverse modification of critical habitat by any activity funded, authorized, or carried out by any Federal agency. As required by section 4 of the Act, the Service considered economic and other relevant impacts prior to making a final decision on the size and configuration of critical habitat.
