Boodereeprovideshabitatforfiveendangeredand11atleastvulnerableanimalspecies,furthermorethemagentalilly-pillyislistedasavulnerableplantwithinBoodereeterritories(DirectorofNationalParks,2009b).In2008,HyderConsultingpreparedareportonbehalfoftheAustraliangovernmentabouttheimpactsofclimatechangeonAustralia’sprotectedareas.ItsummarizesuniquefeaturesofBoodereenationalparkasfollows:Besidestheendangeredspecieswhichwerealreadymentioned,theparkprovided“[o]neofthemostdiversemarineenvironmentsrecordedintemperateAustralia,withtropicalandtemperatespeciesrepresented”(HyderConsulting,2008,p.42).Othermentionedcharacteristicsarelargeseagrassmeadows,exceptionalwaterclarity,theimportanceofBowenIslandasabreedingcolonyforlittlepenguins,andtheprotectionofnaturalsandstoneandduneecosystems.Becauseoftheirendangeredstatus,threatenedspeciesareverysensitiveforenvironmentalimpactsthatcausechangestotheirhabitats.Sincetheparkcoversmarineaswellasterrestrialareas,climatechangeaffectsBoodereefromtwodifferentsides.

AccordingtoHyderConsulting,CO2concentrationisexpectedtoriseby165ppmuntil2030and365ppmuntil2070.Thiswouldleadtoanaverageannualtemperatureincreaseof1.3°Crespectively4.0°C,thuscausinganincreaseofannualdayswithtemperaturesabove35°Cby3daysin2030and15daysin2070.Whiletheaveragesealevelisassumedtoriseby17cminthe2030casescenarioand50cmuntil2070,rainfallnumbersareveryuncertainandcouldeithershowhigherorloweramountofrainfallperyear(HyderConsulting,2008).

2.1FireIntensityandFrequency

Oneofthemostfrequentlymentionedimpactsofclimatechangeistheincreasedriskofbushfires:ResearchshowsthatincreasingCO2levelsarebeneficialforphotosynthesis.Itisthereforeexpectedthattherisingcarbonlevelswillbeadvantageousforundergrowth,thusleadingtomorefuelloadintheforests(DirectorofNationalParks,2010a).TheDirectorofNationalParksconcludesfurther,thatthisfacttogetherwithrisingtemperaturesandincreasedevaporationwillexposeBoodereenationalparktohigherrisksoffire.Fireisexpectedtoappearmorefrequentandintense.Becausesomeplantspeciesisbettercapabletosurvivewildfiresthanothers,itiseasytoinferhowsuchachangewouldbebeneficialformorefireresistantspeciesandinthisway,thenaturalcompositionandfinally,Booderee’sbiodiversitywouldchange(DirectorofNationalParks,2010a).Theimpactoffireisdependentontheinterconnectednessofthelandaswellasthehabitatitselfthatrepresentsobstaclesforfiretospreadoutandspeciestorecoverthroughintroductionfrom

2.2SeaLevelRise

2.3StormIntensityandFrequency

Climatechangecreateschallengesfortraditionalprotectedareasandtheirmanagement.MichaelDunlopandPeterBrownsummarizedthedilemmain2008:Climatechangewillnecessarilyleadtochangesinthenaturalcompositionofterritories.Changingclimateconditionsarebeneficialforsomespeciesandunfavorableforothers.Therefore,specieswillchangegeneticallyaswellasintermsofassemblages.Theywillmoveandsearchforbetterspacestolive,otherswillintrudeinformerhostilehabitats.Extinctionisnotavoidablebutotherendangeredanimalsandplantscouldevenbenefitfromchangedlivingconditions.Climatechangecomeswithtransformationbutquestionsonhowthischangewilllooklikecannotbeansweredforsure(Dunlop&Brown,2008).Climatechangethereforeinevitablyraisesquestionsforeveryprotectedareaanditsmanagement:WhatdoIwanttoprotect?Whataremyconservationgoals?

3.1ClimateChangeStrategy

The2010BoodereeNationalParkClimateChangeStrategyrecommendsthefollowingfivesteps:

1. Understandclimatechangeimplications,

2. implementadaptationmeasurestoenhanceresilience,

3. reducethecarbonfootprintoftheparkanditsmanagement,

4. collaboratewithdifferentstakeholderslikecommunitiesandindustriesinordertodevelopmitigationandadaptationprojects,andfinally

5. communicateinformationaboutclimatechangeandBooderee’smanagementanswerstothepublic(DirectorofNationalParks,2010a).

Inthefirststep,understandingofclimatechangeanditsimplicationsonBoodereeshouldbeenhanced.Thisincludesdisclosureofexistingknowledgegapsandaddressingofthoseincooperationwithresearchinstitutesinordertoallowunderstandingandeliminationofthesegaps.

ExtensionofexistinginformationanddatamanagementsystemsareexpectedtooptimizeconservationeffortsandtosupportariskassessmentprocesstoidentifythelikelihoodofdifferentclimateimpactsonBoodereeinpartnershipwiththeWreckBaycommunity(DirectorofNationalParks,2010a).

Asalreadymentionedintheprevioussection,ParksofAustraliaimplementedthesameclimatechangeactionplanframeworkforallAustraliannationalparks(DirectorofNationalParks,2009a).Themainfive-stepstrategyisadaptedtoeverypark’sindividualneeds.Inthefollowing,Booderee’sclimatechangestrategyiscomparedtotwoothernationalparks.

4.1KakaduNationalPark

Asvisibleinfigure2,KakadunationalparkislocatedatthenorthcoastofAustraliaapproximately125mileseastofDarwin(DirectorofNationalParks,2010b).With7,650squaremiles,theparkismuchbiggerthanBooderee.HalfoftheparkwasgivenbacktotheAboriginalcommunityundertheAboriginalLandRightsActin1976.Sincethen,thelandisleasedbacktotheDirectorofNationalParksinordertobemanagedasKakadunationalpark(DirectorofNationalParks,2016).JustasinBooderee,KakaduismanagedunderanimplementedsharedgovernanceapproachthatincludesaBoardofManagementinwhichtheAboriginalcommunitycollaborateswiththeAustraliangovernment.AccordingtotheDirectorofNationalParks,theparkisfurtherexpectedtobemoreresilienttoclimatechangeimpactsalsobecauseofitssandstonestructureswhichprovideanaccommodatingmicroclimateformanyspeciesthatareendangeredintheconsequenceofclimatechange.

Theclimatechangestrategyfrom2011providesforthesamefive-stepframeworkasalreadydiscussedforBoodereeandKakadu.However,implementationisadaptedtothespecificneedsofthemarine-terrestrialprotectedareaandtherefore,climatechangeimpactsareextendedcomparedtoBooderee:Theredcrabrepresentstheisland’sdominantkeyspecies(DirectorofNationalParks,2011).Becauseitsmigrationisdependentonthestartofthewetseason,rainfallreductionandshiftsinthenaturalrhythmareoneexampleforhowclimatechangecandisturbthesensitivelocalbalanceofflora,fauna,andenvironment.Also,wateracidificationthroughincreasingatmosphericcarbondioxidelevelsandrisingwatertemperaturecouldtriggercoralbleachanddecreasingfishstock(DirectorofNationalParks,2011).Acidificationwouldalsoleadtoaggravatedconditionsformarinelifethatdevelopsacalciumcarbonateshellanddisturbancesinmarinepopulationwouldnotjustaffectthefoodchainbelowthewaterlinebutalsoseabirdspecieswhichisheavilydependentonfish.

ThemanagementplanforChristmasIslanddefinesthegoalregardingclimatechangeasfollows:“TheDirectorwillworkwithstakeholdersandencourage,andwherefeasiblesupport,researchandinvestigationsintopotentialclimatechangeimpacts,andthedevelopmentofmitigationandadaptiveresponses”(DirectorofNationalParks,2014a,p.63).EventhoughthispolicyisformulateddifferentlycomparedtoBooderee’s,thegeneralideaalsoremainsrelativelyvague.Thepolicyisfurtherexplainedbythreeactionswhichshouldbeimplemented:First,climatechangebasedresearchisaskedtobeprioritizedandsupportedtogainmoreknowledgeaboutclimatechangeimpactsonChristmasIslandandadequatemitigationandadaptationstrategies.Second,aclimatechangestrategyshouldbeimplementedandreviewedinordertoimproveparkmanagementaccordingtothelessonslearnedfromresearch.Andlastly,managementprioritiesandprogramshavetobechangedtotaketheresearchoutcomesintoconsideration(DirectorofNationalParks,2014a).ThiscaseagainshowsthattheAustralianclimatechangestrategyratherprovidesagenericframeworkwithinitsbordersconservationgoalsareadaptedifnecessaryinsteadofchangingconservationaimsingeneral.
