We appreciate the cooperation and assistance of your staff and permittees during the consultation period. We look forward to assisting you with the implementation of this biological opinion. If you have any questions on the biological opinion please contact Thetis Gamberg at 520/670-4619, Mima Falk at (520) 670-4550, or Sherry Barrett at (520) 670-4617 of my Tucson staff.

Reinitiation was requested for the following reasons: 1) the Chiricahua leopard frog was listed as threatened on June 13, 2002, and effects from livestock grazing were not evaluated in the previous opinion; 2) the previous biological opinion expired on July 29, 2002; 3) the proposed action has been modified, asking for coverage of all on- going grazing activities for a period of ten years from the date of this opinion; 4) three allotments (A Bar Draw, Paradise, and Dragoon) have been added to the proposed action; 5) revised guidance criteria were issued on April 15, 2002, and all of the allotments had to be reviewed against the new criteria; 6) terms and conditions for several species were not accomplished; and 7) as a result of recent court cases, we were asked to review all of the incidental take statements from the previous opinion to ensure that they met the standards set out in those court decisions (Arizona Cattle Growers Association v. U.S. Fish and Wildlife Service and Bureau of land Management, 97-02416 PHX-SMM [D.Ariz] and Arizona Cattle Growers’ Association v. U.S. Fish and Wildlife Service and U.S. Forest Service, 99-0673 PHX RCB[D.Ariz]). At issue are effects that may result from continuing livestock grazing actions on the Coronado National Forest (Forest) in New Mexico (Hidalgo County) and Arizona (Cochise, Santa Cruz, Pima, Pinal, Graham counties), on the Chiricahua leopard frog (Rana chiricahuensis), New Mexico ridgenose rattlesnake (Crotalus willardi obscurus), Sonora tiger salamander (Ambystoma tigrinum stebbensi), cactus ferruginous pygmy-owl (Glaucidium brasilianum cactorum), southwestern willow flycatcher (Empidonax traillii extimus), Gila topminnow (Poeciliopsis occidentalis occidentalis), Sonora chub (Gila ditaenia), Yaqui chub (Gila purpurea) with critical habitat, lesser long-nosed bat (Leptonycteris curasoae yerbabuenae), Mexican long-nosed bat (Leptonycteris nivalis), Huachuca water umbel (Lilaeopsis schaffneriana var. recurva), and Pima pineapple cactus (Coryphantha scheeri var. robustispina) following section 7 of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). You requested concurrence on the above species, for various allotments, as well as for the American bald eagle, (Haliaeetus leucocephalus), northern aplomado falcon (Falco femoralis septentrionalis), Mexican spotted owl (Strix occidentalis lucida), and jaguar (Panthera onca). You also requested a conference opinion for the Gila chub (Gila intermedia), with critical habitat, a species we proposed for listing as endangered on August 9, 2002, (67 FR 51948). This biological and conference opinion supersedes and replaces the following biological opinions: Arizona: On-Going and Long-Term Grazing for the Coronado NF: 2-21-98-F-399. Arizona: Black Diamond: 2-21-01-F-071. Arizona: Marijilda, Hawk Hollow, Shingle Springs, White Streaks: 2-21-00-F-017. Arizona: Alisos/Sierra Tordilla allotment: 2-21-95-F-293. New Mexico: A Draw, Dragoon, Paradise: 2-22-99-F-016. The terms and conditions issued in the above listed opinions have been incorporated into this opinion. If they are not in this opinion, they have either been met or they have been removed from consideration. You requested formal consultation on May 29, 2002, for livestock grazing activities on the Canelo, Lyle Canyon, and Manila allotments (2-21-02-F-201). Those proposed actions are analyzed herein. Mr. John McGee 4 This biological and conference opinion was prepared using the following information: your July 30, 2002, biological assessment (BA), correspondence between our agency staff, telephone, electronic, and personal conversations, field investigations, correspondence from applicants and the Arizona Game and Fish Department (AGFD), and other sources of information such as revisions, updated and expanded information, and changes from you, peer-reviewed and published literature, and other experts. References cited in this biological opinion are not a complete bibliography of all literature available on the species of concern, livestock grazing and its effects, or on other subjects considered in this opinion. A complete administrative record of this BO is on file at our office. We concur with your determination that the proposed action may affect, but is not likely to adversely affect, the remainder of the species as consulted on in your proposed action as charted in the Allotment Summary Tables, as contained in your July 2002 BA. The rationale for these concurrences are documented in Appendix A, Concurrences.
