Abstract: The U.S. Fish and Wildlife Service (FWS)proposes to reintroduce a nonessential experimentalpopularion of Mexican gray wolves (Canis lupus baikyz]within part of the subspecies’ historic range in thesouthwestern United States. The endangered Mexicanwolf currently is known to exist only in captivity. Underthe Preferred Alternative, commencing in 1997 or assoon thereafter as practical, the FWS will graduallyrelease up to 15 pairs or family groups into the BlueRange area of east-central Arizona. If it is determined tobe both necessary and feasible, up to five pairs or familygroups may be released into the back-up area, the WhiteSands Missile Range of south-central New Mexico. Theobjective is ro re-establish 100 wild Mexican wolvesdistributed over 5,000 mi’ by about the year 2005. TheFWS and cooperating agencies will closely monitor,study, and evaluate the reintroduction. They will haveauthority under a Mexican Wolf Experimental Popula-tion Rule to actively manage the wolves, includingpreventing dispersal outside the designated wolf recoveryareas and moving or removing any wolves causingsignificant conflicts.

The key impacts of the Preferred Alternative analyzedin the Final Environmental Impact Statement (FEIS) areas follows. tier the wolf population grows to approxi-mately 100, it is projected to kill between one and 34cattle annually, mostly calves. A private livestock depreda-tion compensation fund exists. For the Blue Range WolfRecovery Area, the net long term effect on wild ungulatesis projected to be between 1,200 and 1,900 fewer elk, andbetween 4,800 and 10,000 fewer deer, than would occurif there were no wolves. If the back-up White Sands Wolf

Recovery Area is used, the net long term effect is pro-jected to be between 760 and 2,000 fewer deer thanwould occur if there were no wolves. Densities of coyotesand mountain lions probably will drop in occupied wolfrange. The major regional economic impacts will bereductions in the value of ungulate hunting and inhunting expenditures. Some regional economic benefitsare expected from increases in tourism and in non-hunting recreation associated with the wolf. Limitedminor land use restrictions may be imposed aroundoccupied release pens, dens, and rendezvous sites, onpublic lands only, as necessary to prevent disturbance ofthe wolves. The use of M-44s and choking neck snares inoccupied wolf range will be restricted. If the White SandsMissile Range is used, some inconvenience, but no majorconflicts with military or testing uses, are expected fromwolf reintroduction.

The FEIS also analyses potential impacts of threealternatives to the Preferred Alternative: 1) reintroductionof nonessential experimental wolves limited to signifi-cantly smaller recovery areas, 2) reintroduction of wolves,in the Blue Range Wolf Recovery Area only, with full“endangered” status under the Endangered Species Actand no restriction of wolf dispersal by managers, and 3) a“No Action” alternative that considers the speculativepossibility of natural recolonization of wolves fromMexico into southeastern Arizona, southwestern NewMexico, and Big Bend National Park in Texas.

The FEIS will be given to decision makers in theFWS and Department of Interior for a decision. A Noticeof Availability of the FEIS will be published in theFederal Register. A Record of Decision can be approved30 days afier publication of the Notice of Availability.Any decision on Mexican wolf recovery in the southwest-ern United States will be well publicized.

• Final Environmental Impact Statement - Reintroduction of the MexicanWolf Within Its Historic Range in the Southwestern United States

Summary

Introduction

The United States Department of the Interior, Fishand Wildlife Service (FWS), proposes to reintroducea nonessential experimental population of Mexicangray wolves (Canis Lupus buikyi) within part of thesubspecies’ historic range in the southwestern UnitedStates. The endangered Mexican wolf currently isknown to exist only in captivity. The FWS hasprepared a final environmental impact statement(FEIS) on its reintroduction proposal and threealternative approaches to re-establishing the subspe-cies under the Endangered Species Act (ESA). ThisSummary outlines the full FEIS.

States and Counties Where thePreferred Alternative is Located

Arizona: Apache and Greenlee Counties; NewMexico: Catron, *Dona Ana, Grant, *Lincoln,*Otero, Sierra, and *Socorro Counties.(* indicates counties that are potentially affected bythe Preferred Alternative only if the back-up WhiteSands Wolf Recovery Area is used.)

Scoping, Public Review, andChanges to the Draft EIS

This FEIS is based on a lengthy period of scoping,preparation, review, and revision of a draft EIS(DEIS). Fo u r up blic scoping meetings were held in199 1 and 1992 to obtain public input regarding theFWS’s general proposal to reintroduce Mexicanwolves. A total of 838 people attended. In addition,

ii

public comment periods following the meetingsresulted in 1,324 written comments, which the FWScompiled and analyzed. The seven main areas ofpublic concern related to: 1) the FWS’s planning ofthe Proposed Action and the alternatives to it; 2)impacts of wolf depredation on livestock; 3) eco-nomic impacts; 4) ecological and biological impactsof wolf recovery; 5) the viability of the captiveMexican wolf population; 6) impacts on wildlifemanagement; and 7) philosophical and ethicalconcerns. The interagency Mexican Wolf EIS Inter-disciplinary Team, which oversaw the writing of theEIS, considered these issues as well as additionalissues.

The DEIS was prepared between 1993 and1995; it was released in June 1995. The publiccomment period on the DEIS ended more than fourmonths later, on October 3 1. Public review wasextensive, with participation by almost 18,000people or organizations, in a variety of ways. Four-teen public open house meetings were held through-out the potentially affected areas; total registeredattendance was 1,186. Three formal public hearingswere held in Austin, Texas; Phoenix, Arizona; andSocorro, New Mexico; total registered attendancewas 95 1. Each written and transcribed oral commenthas been reviewed and considered in the preparationof the FEIS. The public comments are on file andavailable for inspection at the FWS Regional Of&ein Albuquerque, New Mexico.

Notable changes from the DEIS to this FEIS arelisted below; they largely are in response to com-ments received on the DEIS or to developmentssince the DEIS was written. Also, numerous minorcorrections, revisions, and updates have been made.

Alternatives

. Re-writing of the Proposed Action as thePreferred Alternative (Ah. A), now specifyinguse of the biologically preferable Blue RangeWolf Recovery Area (BRWRA) first, with theWhite Sands Wolf Recovery Area (WSWRA)as a back-up, only to be used if necessary andfeasible and if additional information isavailable that the deer population cansupport a wolf population. The specific

• decision criteria in the DEIS regardingwhether to use the BRWRA or WSWRAfirst have been deleted.

. Deletion of the provision for closingbackcountry roads.

. Alt. B now proposes reintroductions in boththe BRWRA and WSWRA primary recoveryzones at the same time.

. Alt. C now proposes fUll-endangered wolfreintroduction into the BRWRA only. TheWSWRA is deleted as a potential reintroduc-tion area under Ah. C, largely because thereintroduction objective could be met withreleases to just the BRWRA with subsequentunlimited expansion of the reintroducedpopulation. Related discussion of impacts tothe WSWRA and the adjacent potentialdispersal areas is deleted.

. Rewording of Alt. D to emphasize the “NoAction” aspect and that natural recoloniza-tion is very speculative. Costs of this alterna-tive are re-calculated. Less quantification isprovided in the impact discussion due togreater emphasis on uncertainty.

Clarifications/Corrections

. More discussion of historic informationabout wolf depredation on livestock, inChap. 1 under Reasons for Listing.

. New or more clear definitions of “problemwolves, ” “rendezvous sites,” and “distur-bance-causing land use activities” in theGlossary, Appendix G. The latter definitionincludes specific activities and types of publicaccess that may not be allowed within aradius of one mile or less around active pens,dens, and rendezvous sites, as well as exemp-tions, i.e., activities specifically allowed.

. Deletion of the provision for removingwolves when they are “conflicting with amajor land use”; addition of a provision forremoving them if they endanger themselves

by occurring when and where military ortesting activities are scheduled.

. Clarification that modification of wolfhabitat (outside the protection areas forpens, dens, and rendezvous sites) by landuses in the recovery areas would not beconsidered a “take” of nonessential experi-mental wolves under ESA sec. 9(a).

. Apportionment of potential impacts on deer,elk, hunting, and related economic impactsby whether they would occur in Arizona orNew Mexico.

. Discussion of potential impacts on bighornsheep in the BRWRA.

. More discussion of potential impacts on theSan Carlos Apache Reservation.

Mexican Gray Wolf Description

Background

The Mexican wolf is the southernmost and one ofthe smallest subspecies of the North American graywolf. Adults weigh 50 to 90 lbs., average 4’6” to 5’6”in total length, and reach 26” to 32” in height at theshoulder. Its pelt color varies. The “lobo”-itspopular name-is genetically distinct from otherwolves and no confirmed population exists outsidecaptivity. It is one of the rarest land mammals in theworld. International experts rate recovery of theMexican wolf subspecies as the highest priority of allgray wolf recovery programs.

Reasons for Listing

Many factors contributed to the Mexican wolf’sdemise, but the concerted federal eradication effortin the early 1900s was predominant. Other factorswere: commercial and recreational hunting andtrapping; kiliing of wolves by game managers on thetheory that more game animals would be availablefor hunters; habitat alteration; and safety concerns,although no documentation exists of Mexican wolfattacks on humans.

Reintroduction Procedures

All Mexican wolves to be released under AlternativesA, B, and C, below, would come from the certifiedU.S. captive population of 114 animals (as of March1996) maintained in 24 zoos, wildlife parks, andother facilities located around the country. Thewolves have exhibited no major genetic, physical, orbehavioral problems affecting their fitness resultingfrom captivity. The FWS will move male/femalepairs identified as candidates for possible release toits captive wolf management facility on the SevilletaNational Wildlife Refuge, north of Socorro, NewMexico. In the event of a decision to proceed withreintroduction, the FWS would select release ani-mals from among the candidate pairs based onreproductive performance, behavioral compatibility,response to the adaptation process, and other factors.Only wolves that are genetically well-represented inthe remaining captive population would be used asrelease stock.

iv

• Alternatives

Alternative A (the Preferred Alternative): TheU.S. Fish and wildlife Service proposes toreintroduce Mexican wolves, classified asnonessential experimental, into the Blue RangeWolf Recovery Area. Wolves will be released intothe primary recovery zone and allowed to dis-perse into the secondary recovery zone. If fea-sible and necessary to achieve the recoveryobjective of 100 wolves, a subsequent reintroduc-tion of wolves into the White Sands Wolf Recov-ery Area will be conducted.

In 1997, the FWS will begin to reintroduce familygroups of captive-raised Mexican wolves into theprimary recovery zone of the BRWRA (Fig. 1). TheFWS will gradually release up to 15 family groupsinto the BRWRA and later, if necessary and feasible,up to five family groups into the back-up WSWRA(Fig. 1). Reproduction in the wild would increasethe populations to approximately the recoveryobjective. Wolves will be released into the primaryrecovery zone and allowed to disperse into thesecondary recovery zone.

The recovery objective of the Preferred Alterna-tive is to re-establish 100 wild wolves distributedover more than 5,000 mi2 by about the year 2005,consistent with the 1982 Mexican Wolf RecoveryPlan. The FWS projects that the population willeventually fluctuate near this level as result of naturalprocesses, such as intra-specific aggression andchanges in prey abundance and vulnerability, andmanagement actions, such as problem wolf controland translocation. The FWS and its cooperators willmonitor, research, evaluate, and actively manage thewolves, including translocating or removing wolvesthat disperse outside the wolf recovery areas or thatcause significant conflicts.

A federal regulation will designate the popula-tion to be released as experimental and nonessentialto the continued existence of the subspecies. ThisMexican Wolf Experimental Population Rule willdelineate the precise geographic boundaries (see Box1) and prescribe the protective measures andmanagement authority that apply. No formal ESASection 7 consultation would be required regardingpotential impacts of land uses on nonessentialexperimental Mexican wolves, except on NationalWildlife Refuges and National Park Service areas.

V

Summary

Reintroduction will occur under managementplans that allow dispersal by the new wolf popula-tions from the immediate release areas (“primaryrecovery zones”) into designated adjacent areas(“secondary recovery zones”) (Fig. 1). However, theFWS and cooperating agencies will not allow thewolves to establish territories outside these wolfrecovery area boundaries unless this occurs onprivate or tribal lands and the land manager does notobject. The FWS would attempt to enter intocooperative management agreements with suchlandowners regarding control of the wolves. If theland manager objects to the presence of wolves onprivate or tribal lands, field personnel would recap-ture and relocate the wolves.

The FWS and the cooperating agencies will usea flexible “adaptive management” approach based oncareful monitoring, research, and evaluationthroughout the release phase. This will includeadjusting the numbers actually released according tothe needs and circumstances at the time. Initially, toreduce the likelihood of wolf dispersal onto theWhite Mountain Apache and San Carlos Apachereservations to the west, the wolf releases will occuron the eastern side of the BRYVRA primary recoveryzone, close to the Arizona/New Mexico border. TheFWS will encourage and support the formation of aCitizen Advisory Committee, or similar manage-ment oversight body, to assist the FWS and cooper-ating agencies in responding to citizen concerns.

The following future circumstances will beconsidered in decision-making about using theWSVURA subsequent to initial releases in theBRWRA:

. whether using the WSWRA, in combinationwith the BRWRA, is necessary to achieve therecovery objective of re-establishing 100wolves; that is, it would be used if it appearsthat the initial introduction in the BRWRAwill not achieve a total population of 100wolves,

. whether, based on future research, it appearsthat the WSWRA deer herd could support awolf population that would contribute tomeeting the recovery objective, and

. other future circumstances that could affectthe feasibility of using the WSWRA, such as

the wolf program budget, managementconcerns, future military uses of the missilerange, and so on.

The Proposed Mexican Wolf ExperimentalPopulation Rule was published in the FederalRegister on May 1, 1996 (pp. 19237-19248). Insummary, the Proposed Rule provides:

. No one will be in violation of the ESA forunavoidable and unintentional take of a wolfwithin the Mexican wolf experimentalpopulation area when the take is incidentalto a legal activity, such as driving, trapping,and military testing or training activities, andis promptly reported. Anyone may take awolf in defense of human life.

. No private or tribal land use restrictions willbe imposed for wolf recovery without theconcurrence of the private owner or tribalgovernment. On public lands, public accessand disturbance-causing land use activitiesmay be temporarily restricted within a one-mile radius around release pens, and aroundactive dens between March 1 and June 30and around active wolf rendezvous sitesbetween June 1 and September 30.

. On public lands allotted for grazing, livestockowners and their designated agents: (1) mayharass wolves for purposes of scaring themaway from livestock provided the harassmentis promptly reported, and (2) may be al-lowed to take wolves actually engaged inattacking livestock.

vii

• . Permission for private parties to take wolveson public grazing lands must meet all ofthese conditions: 1) six or more breedingwolf pairs occur in the BRWRA, or three ormore breeding wolf pairs occur in theWSWRA (if used); 2) previous livestock lossor injury by wolves has been documented byan authorized FWS, ADC, or state employeeand efforts to control the offending wolveshave been undertaken but have not succeed-ed; 3) physical evidence exists that an attackoccurred at the time of the take; and 4) thetake is promptly reported.

. On private or tribally-owned land, regardlessof location, property owners and livestockowners and their designated agents mayharass wolves near livestock, people, build-ings, facilities, pets, or other domesticanimals at any time and may take wolvesattacking livestock under more liberalconditions than those applicable to publicgrazing lands. That is, such take can occurregardless of the number of recovered wolfpairs in the area and no requirement existsfor government agencies to have completedtheir efforts to take the depredating wolves.However, physical evidence that an attackoccurred at the time of the take must bepresent and the take must be promptlyreported.

. Any FWS-authorized person may captureand remove or translocate reintroducedwolves consistent with a FWS-approvedmanagement plan or special managementmeasure. These may include wolves that: (1)prey on livestock, (2) attack domestic ani-mals other than livestock on private land, (3)impact game populations in ways which mayinhibit further wolf recovery, (4) prey onstate-endangered desert bighorn sheep onthe White Sands Missile Range (if used), (5)are considered problem wolves, are a nui-sance, or endanger themselves by theirpresence in a military impact area, or (6) arenecessary for research.

. The FWS does not intend to change the“nonessential experimental” designation to

Summary

“‘essential experimental” or “endangered” andthe FWS does not intend to designatecritical habitat for the Mexican wolf.

. Any taking of a wolf contrary to the experi-mental population rule may be referred tothe appropriate authorities for prosecution.

Post-release management will follow an inter-agency cooperative management plan. This willinclude working with the Arizona Game and FishDepartment to meet the requirements of itsCooperative Reintroduction Plan and working withthe New Mexico Department of Game and Fish. Awolf management team representing the FWS, theState Game and Fish departments, and othercooperating agencies will determine whether particu-lar actions are necessary. The interagency manage-ment plan will cover issues such as release pen siting,veterinary management, depredation control,capture and relocation, research, radio tracking,aerial overflights, prey monitoring, and prey habitatmanagement. Field staffwill conduct monitoringand research, trapping, depredation investigation,mortality investigation, control, and other on-the-ground actions.

Alternative B: Reintroduction of Mexicanwolves, classified as nonessential experimental,into both the Blue Range Wolf Recovery Areaand the White Sands Wolf Recovery Area pri-mary recovery zones. Wolves dispersing from theprimary recovery zones will be captured andreturned to the primary zones or captivity.

In 1997, the FWS will begin to reintroduce familygroups of captive-raised Mexican wolves into boththe BRWRA and the WSWRA primary recoveryzones and actively prevent the populations fromexpanding beyond these zones (Fig. 1). In theBRYVRA primary recovery zone the FWS will releaseabout eight family groups over four years with thegoal of reaching a population of 20 wild wolves by200 1. In the WSWRA primary recovery zone theFWS will release about four family groups over twoyears with the goal of reaching a population of 14wild wolves by 1999. The total recovery objectivewill be 34 wolves.

be takings to protect human life or by special permit“for scientific purposes or to enhance the propaga-tion or survival of the affected species,” 16 USC sec.1539(a)(l)(A).

Land use restrictions could be imposed underthis alternative. Restrictions could include limitingthe use of predator control methods that might killor injure wolves, closing roads, modifying livestockgrazing, and imposing other protections to limit anyjeopardy resulting from human activities. Otherfederal agencies would be expected to pursue theirresponsibilities under the ESA to conserve, and notharm, a recolonizing population. This would includemanaging to maintain and create high qualityungulate and wolf habitat.

The FWS will designate the population asnonessential experimental under the ESA. The FWSwill adopt basically the same Mexican Wolf Experi-mental Population Rule as under Ah. A, but itwould apply to the smaller areas. The FWS and itscooperators will follow the same release, monitoring,and management procedures as under Ah. A, but ona smaller scale due to the smaller areas involved.Control will be accomplished through a combi-nation of aggressive monitoring and managementmethods to promptly recapture wolves that leave theprimary recovery zones. Wolves could be translo-cated between the two areas as needed.

Alternative C: Reintroduction of Mexicanwolves, classified as endangered, into the BlueRange Wolf Recovery Area only. Wolves will bereleased into the primary recovery zone andunlimited dispersal will be allowed. Wolves willreceive full protection under the EndangeredSpecies Act.

In 1997, the FWS will begin to reintroduce familygroups of captive-raised Mexican wolves under theircurrent full-endangered status into the primaryrecovery zone of the BRWRA in east-central Ari-zona, following the same release procedures as underAlt.s A and B. The FWS will gradually release up to15 family groups into the BRWRA. No releases willoccur in the WSWRA. The recovery objective of thealternative is to re-establish 100 wild wolves dis-tributed over more than 5,000 mi2 by about the year2002, consistent with the Mexican Wolf RecoveryPlan. The FWS and its cooperators will monitor andconduct research on the wolves, but they will notactively manage them.

The ESA allows unrestricted dispersal; that is,the FWS will not restrict the population to thedesignated wolf recovery areas, as under AlternativeA, or to the smaller primary recovery zones, as underAlternative B. No attempts will be made to recaptureor return wolves with the possible exception ofindividual depredators.

The wolves will have the full protection against“take” by humans provided by the ESA. Anyonewho would “harass, harm, pursue, hunt, shoot,wound, kill, trap, capture, or collect, or attempt toengage in any such conduct” against a Mexican wolfwill be violating the ESA. The only exceptions will

Alternative D: No Action

Under the No Action alternative, the FWS will takeno action other than continuing its present course. Itwill neither release wolves nor take any other steps todirectly ensure Mexican wolf recovery. The FWS willneither adopt an experimental population rule nordesignate any wolf recovery areas. The agency willcontinue to support the captive population objec-tives established in the SSP Master Plan, but theagency will not support breeding for maximumgrowth.

Based on its current ESA obligations, the FWSwould still encourage protection and expansion ofwild wolf populations under this alternative, if anywere discovered. No evidence exists to indicate alikelihood of natural recolonization in U.S. portionsof the historic Mexican wolf range, but the FWS willsupport continued research on this possibility. Natu-ral recolonization is considered extremely specula-tive. Based on historical wolf abundance, recentsighting reports alleged to be wolves, proximity toMexico, and other factors, the most suitable areas forpotential natural recolonization by wild wolvesprobably would be the mountainous parts of south-eastern Arizona and southwestern New Mexico, andBig Bend National Park in southern Texas. Thisalternative analyzes these three areas. No confirmedsighting reports have come from these areas or fromMexico in recent years.

Any wolves that did naturally recolonize wouldbe fully protected as an endangered species in theUnited States. It would be illegal to harm or harass

ix

• them except under very narrow circumstancesauthorized by an ESA permit.

Land use restrictions could be imposed underthis alternative depending on if, and where, wolvesoccurred. Restrictions could include limiting the useof predator control methods that might kill or injurewolves, closing roads, modifying livestock grazing,and imposing other protections to limit any jeopar-dy resulting from human activities. Other federalagencies would be expected to pursue theirresponsibilities under the ESA to conserve, and notharm, a recolonizing population. This would include
