The11thMountainLionWorkshopwasheldatSouthernUtahUniversityinCedarCity,UtahfromMay12to15,2014.Thethemeoftheworkshopwas“IntegratingScientificFindingsintoManagement.”Dr.JohnLinnell,NorwegianInstituteforNatureResearch,Trondheim,Norway,gavetheKeynoteAddress.Dr.Linnell’sinspiringpresentationontheecologyandstatusofEurasianlynxprovidedmanycomparableinsightstomountainlions,anotherwidespreadspecieswithahighlyvariablestatus.AttheWednesdaynightbanquetDr.MikeWolfe,EmeritusProfessoratUtahStateUniversity,gaveanotherexcellentpresentationwithatalkentitled“Predation:theroadfrommythtoreason.”

Sessiontopicsincluded:stateandprovincereports;felidecology,conservationandpopulations;predatorsandprey;felidsandhumans;non‐invasivetechniques;andmanagementstrategies.Allofthepresentationswereprofessional,timely,andwell‐attended.PresentationsfocusedonpumaresearchandmanagementinthewesternU.S.(including3onrecentlyrecolonizedpopulationsintheDakotas)andCanada,withtwoadditionaltalksontheFloridaPanther.ToprovideinsightsintopumamanagementandconservationconcernsoutsideofNorthAmerica,WFAsponsoredDr.MauroLucherini,UniversidadNacionaldelSurinArgentina,whosetalkexaminedpuma‐livestockconflictsintheEspinalofCentralArgentina.

Alongwithover50presentations,fifteenpostersweredisplayed,withtopicscoveringdiseases,feedingecologyanddiet,orphans,GPSlocationclusteranalysis,rangeexpansion,effectsofambientlight,comparisonsofnoninvasiveandinvasivemethodsofpopulationmonitoring,compensatoryandadditivemortality,andpuma‐humanconflicts.Twosessionsincludedfollow‐uppaneldiscussions.Duringa2‐hour,WFA‐sponsoredsessionWednesdaymorning,DavidStonermoderatedapredator‐preysessionthatincluded5invitedspeakers(BeckyPierce,DavidChoate,AlysonAndreasen,JeffVillepique,andMarkHurley)withintimateknowledgeaboutspecificpredator‐preysystems.Presentersdiscussedtop‐downversusbottom‐up

INTRODUCTIONIn2007,Wyomingbeganmanagingmountainlionpopulationsunderanadaptivemanagementplan,withharvestlimitssettoachievestable,source,orsinkpopulationobjectiveswithinfivemountainlionmanagementunits(MLMUs)acrossthestate.

Primarymonitoringcriteriawereestablishedviaempiricallytestedresearch

(AndersonandLindzey2005),whichprovidedinsighttogeneraltrendsinmountainlionpopulationsundervariousconditionsandhuntingpressures.Telemetrydatawerecollectedfromasampleofvariouscohortsofmountainlionsthroughouttestandreferenceareaswithinthestate,andpopulationestimateswereestablishedthroughmark‐recapturetechniques.Locationdatafromthesesampleswerealsousedinaresourceselectionfunctionanalysistoestimateandmapsuitablemountainlionhabitat.Huntingpressurewasappliedtotestareastoincreasemountainlionmortalityandtoestimateamortalitydensitythatresultedindecreasingpopulationestimates.Whenhuntingpressurewasrestricted,mortalitydensitieswereagainestimatedtodeterminethelevelatwhichpopulationestimatesrebounded.Ageandsexcompositionofmortalitydatawerealsogatheredthroughoutthisprocess.Generally,asrelativemortalityincreased(numberofmortalities/unitareaofsuitablehabitat),ahigherproportionofadultfemaleswere
