United States Department of the Interior U.S. Fish and Wildlife Service 2321 West Royal Palm Road, Suite 103 Phoenix, Arizona 85021-4951 Telephone: (602) 242-0210 FAX: (602) 242-2513 In Reply Refer To: AESO/SE 22410-2007-F-0132 June 14, 2007 02-21-02-F-229 02-21-98-F-266 Colonel Jonathan B. Hunter Commander, U.S. Army Garrison 2837 Boyd Avenue, Rodney Hall Fort Huachuca, Arizona 85613-7001 Dear Col. Hunter: Thank you for your request for formal consultation with the FWS pursuant to section 7 of the Endangered Species Act of 1973 (16 U.S.C. 1531-1544), as amended (Act). Your request was dated December 28, 2006, and received by us on December 29, 2006. We transmitted a letter requesting additional information on January 11, 2007. Your submittal of additional information was dated February 12, 2007, and was received by us on February 14, 2007. At issue are impacts that may result from the proposed ongoing and future military operations and activities at Fort Huachuca, Cochise County, Arizona. The proposed action may affect the endangered Huachuca water umbel (Lilaeopsis schaffneriana var. recurva) and the species’ critical habitat, the endangered southwestern willow flycatcher (Empidonax traillii extimus) with critical habitat, the threatened Mexican spotted owl (Strix occidentalis lucida), the endangered lesser long-nosed bat (Leptonycteris curasoae yerbabuenae), and the endangered Sonora tiger salamander (Ambystoma tigrinum stebbinsi). You also requested formal consultation on the Huachuca springsnail (Pyrgulopsis thompsoni), a candidate for Federal listing, and the Ramsey Canyon leopard frog (Rana subaquavocalis), which lacks any Federal status at this time, and you requested informal consultation on the yellow-billed cuckoo (Coccyzus americanus), a candidate for Federal listing. We do not consult nor confer on actions that affect species that are not proposed or listed under the Act. We will, however, provide technical assistance on these species at your request. In your December 28, 2006, and February 14, 2007, letters, you requested our concurrence with your determination that the proposed action may affect, but is not likely to adversely affect the endangered Canelo Hills ladies’ tresses (Spiranthes delitescens); the threatened bald eagle (Haliaeetus leucocephalus); the endangered jaguar (Panthera onca); the threatened spikedace (Meda fulgida) with then proposed, now final critical habitat; the endangered Gila topminnow (Poeciliopsis occidentalis occidentalis), and the endangered desert pupfish (Cyprinodon macularius) with critical habitat. We concur with your determinations for these species, and have provided our rationales in Appendix A. Your December 28, 2006, letter also stated that you had determined your proposed action would have no effect on the threatened Cochise pincushion cactus (Coryphantha robbinsorum), Colonel Jonathan B. Hunter 2 candidate Lemmon fleabane (Erigeron lemmonii), endangered northern aplomado falcon (Falco femoralis septentrionalis), endangered Ocelot [Leopardus (=Felis) pardalis], threatened Chiricahua leopard frog (Rana chiricahuensis), threatened New Mexico ridge-nosed rattlesnake (Crotalus willardi obscurus), endangered California brown pelican (Pelecanus occidentalis californicus), endangered Gila chub (Gila intermedia), threatened beautiful shiner (Cyprinella formosa), threatened Yaqui catfish (Ictalurus pricei), endangered Yaqui chub (Gila purpurea), and the endangered Yaqui topminnow (Poeciliopsis occidentalis sonoriensis). We recommend that you maintain a complete administrative record documenting the decision process and supporting information for these determinations. This draft biological opinion is based on information provided in: (1) the December 2006 Programmatic Biological Assessment for Ongoing and Future Military Operations and Activities at Fort Huachuca, Arizona (PBA); (2) the February 2007 addendum to the PBA (Revised PBA); (3) meetings, telephone conversations, and exchanges of electronic mail between our respective staffs; and (4) other published and unpublished sources of information. Literature cited in this biological opinion is not a complete bibliography of all literature available on the species of concern or the effects of military operations on fish, wildlife, and plants, or on other subjects considered in this opinion. A complete administrative record of this consultation is on file at the Arizona Ecological Services Office (AESO). Consultation History • August 23, 2002: We transmitted to you our final biological opinion (File nos. 2-21-02- F-229 and 2-21-98-F-266) of the effects of activities authorized, carried out, or funded by the Department of the Army at and near Fort Huachuca (Fort), Arizona on the Huachuca water umbel and critical habitat, southwestern willow flycatcher, Mexican spotted owl with critical habitat, lesser long-nosed bat, and Sonora tiger salamander. The proposed action was found to not jeopardize these species, nor adversely modify critical habitat where designated. • March 16, 2006: We received your March 10, 2006, letter stating that preparation of the PBA was underway. • June 21, 2006: You transmitted to us a letter stating your intent to reinitiate formal consultation. • January 11, 2007: We transmitted to you a letter (File nos. 22410-2007-I-0132, 2-21-02- F-229, and 2-21-98-F-266) acknowledging the receipt of your PBA and outlining the additional information we required in order to complete formal consultation on the proposed action. • February 14, 2007: We received your February 12, 2007, response to our January 11, 2007, request for additional information. Your letter included a revised PBA and appendices. Though sufficient information was received with which to complete formal consultation, we did not respond with a letter to that effect. • May 24, 2007: We transmitted the draft biological opinion to you. Colonel Jonathan B. Hunter 3 • June 7, 2007: We received your June 5, 2007, comments on the draft biological opinion. BIOLOGICAL OPINION DESCRIPTION OF THE PROPOSED ACTION The following narrative has been adapted directly from the Revised PBA to ensure an accurate description of the proposed action, including the proposed conservation measures. The proposed action includes programmed facilities development projects on the installation, resource management, recreation, and other land uses. This section concludes with summary descriptions of operations and activities that occur in, or are programmed for, training areas across the installation. This section incorporates the conservation measures in Section 5 of the Revised PBA, which will be implemented by Fort Huachuca as part of the proposed action. These conservation measures will also be restated in the section entitled Description of the Proposed Conservation Measures, which follows. The ongoing and future military operations and activities at Fort Huachuca that are evaluated in the Revised PBA and this biological opinion do not include the potential for a Base Realignment and Closure (BRAC) action. There is a potential for another BRAC to occur within the 2011- 2014 timeframe, at which time Fort Huachuca could be significantly affected, either by realignment or closure. If Fort Huachuca is part of a BRAC action in the future, it will be covered under a separate consultation. Baseline Operations, Activities, and Missions The ongoing missions and activities at Fort Huachuca constitute the baseline at the installation. Additional activities and missions that have occurred since the 2002 BA are included in the operational baseline. These include increases in military intelligence training load, classrooms, single soldier housing and testing and training facilities [Environmental Assessment (EA), Dec 2001 and EA, Nov 2004], the replacement of two elementary schools on Fort Huachuca, Rehabilitation of Historic Adobe Structures at Fort Huachuca, Arizona (EA, March 2002), Implementation of an Integrated Cultural Resources Management Plan (EA, August 2002), Construction and Operation of a DOD HUMINT Training Center, Fort Huachuca (EA, November 2002), Construction and Maintenance of a Security Fence for LAAF/Sierra Vista Municipal Airport at Fort Huachuca, AZ (EA, April 2003), Future Development Master Plan for the Joint Interoperability Test Command (EA, May 2004), Wilcox Gate Area Development Plan (EA, May 2004) and USAIC Future Development Plan (EA, November 2004). This section also includes several proposed actions for which NEPA analysis is either completed or in progress, but the decisions to implement the projects have not been made. These projects include: a proposed Air National Guard UAV squadron, a renewable energy Environmental Assessment (EA) in draft, expanded border patrol activities at Fort Huachuca to include UAV activities, expansion of Sites Papa and Uniform, range improvements to include upgrading Range 13, creating a convoy live-fire course on the east range, establishing a forward operating base at Site Maverick, developing a Military Operations Urban Terrain Facility, creating an unmanned aerial systems training battalion, establishing an EPG multipurpose building and UAV runway on the east range, and establishing a Joint Center of Excellence for MI training. Colonel Jonathan B. Hunter 4 Intelligence and communications systems testing and training activities account for nearly 95 percent of training range use (USAIC&FH, 1997). Other supported activities on the installation include field training exercises, aviation activities, live-fire qualification and
