Watch at: 00:00 / 00:00:20good afternoon everyone and welcomemy name is caitlin basat and i'm thekamloops youth facilitator with theinvasivespecies council of bc uh thank you forjoining us for today's webinartitled impacts of invasives in nationalparkspeter charlton invasive plant programleadWatch at: 00:20 / 00:40for mount rebel stoke and glaciernational parks will speak abouthow invasive species impact native floraand fauna so i hope you all had a chanceto sign in early and get any technicalglitches worked out if you experienceany technical difficulties throughoutthe webinar you can just write a note inthe chat boxand our iscbc technical support willWatch at: 00:40 / 01:00send you a private chat to help you outalso if you have any questions duringthe webinar you canfeel free to pop those into the q a boxwhich is located at the bottom of yourzoom windowand then at the end of the webinar wewill have time toanswer the questions if for some reasonWatch at: 01:00 / 01:20we runout of time we will send out an emailwith the questions and answers after thewebinarso to begin we'd like to find out who ishere and where you're all fromwhere you're where you work and whatyour areas of interestare so if you could pop those into thechat and then we'll have time to reviewWatch at: 01:20 / 01:40those while i'm introducing peterso today's webinar is presented by petertarletonpeter is the resource management officerwith parks canadafor the past year he has led theinvasive alien plant programin mount rebel stoke and glaciernational parksprior to that peter spent six yearsWatch at: 01:40 / 02:00leading invasive plant managementand riding mountain national park inmanitobainvasive plant management in a nationalpark presents unique challenges andapproachesthan in neighboring areas whereagricultural or economic impacts are agreater focuswhile park managers benefit from workingin largely intact landscapesWatch at: 02:00 / 02:20visitation creates a challenge incontrolling the spread of invasivespeter will discuss unique approaches toinvasive species management planningin national parks and at this pointi am happy to welcome peter so peter iwill passthe mic over to you and i hope everyoneenjoys the webinarWatch at: 02:20 / 02:40yeah uh like i said i'm pete tarletonum i'm currently here in surprisinglysunnyuh revelstoke um at the foot of rebelstoke national parkum and i'll talk be talking today kindofgenerally about umimpacts of native species of all sortsacrossWatch at: 02:40 / 03:00uh national park system in canadatry to give everybody kind of a broadoverview and then if we've got some timeat the end i'll kind ofclose in on my personal experienceswith mount ravelstokeand glacier national parks and ourprogram here how we manage invasiveWatch at: 03:00 / 03:20speciesand if we really have extra time andi've vastly overestimated uhhow fast i can talk um[Music]or under how fast i could talk i will uhtalk aboutthe experience in riding mountainnational park which is uh what you seein the background there with a nicefield of invasive smooth bromeWatch at: 03:20 / 03:40so um just to start things off i alwayslike tofamiliarize everybody with what nationalparksare not everybody's familiar often timesso yeah national park prevention parkit's a little different so we area federal agency parks canada we operateWatch at: 03:40 / 04:0047 national parks and park reservesright acrossthe government are right across thecountryuh and we are umoperate under the federal minister forenvironment and climate changeum we also operate a whole bunch ofother stuff that doesn't get talkedWatch at: 04:00 / 04:20about as often butcan be pretty important so we operatefour national marine conservation areas171out of 900 some national historic sitesnine canalsa national landmark up in northwestterritoriesand a national urban park inWatch at: 04:20 / 04:40toronto the rouge soas you can see in the map there it's abig system covers a lot of territoryand covers huge portion of the countryum andthis system is operated on aWatch at: 04:40 / 05:00succinct oh and somebody's just tellingme that you can't see my screenso i'm gonnagive me one second i willshare that for youWatch at: 05:00 / 05:20sorry about that folksand hmmsharing my screen britney can you seeWatch at: 05:20 / 05:40thatuh i can peter you're just gonna have touhi'll i'll message you here just give meone momentsorry folkscan you see that there brit peter we canWatch at: 05:40 / 06:00see it thank youokay perfect thanks all right yeah justshout at me if uhanything goes awry againum okay so uhpark standards mandate to operate acrossthat map that i now have up therehopefullyuh is that on behalf of the peopleWatch at: 06:00 / 06:20canada we protectthat's very important and presentnationally significant examples ofcanada's national cultural heritage andfoster public understanding appreciationenjoymentin ways that ensure the ecological andcommemorative integrity of these placesfor present and future generations sothat's a lotuh it's a bit of a multiple but it'sWatch at: 06:20 / 06:40um a really important starting point forunderstanding how we make decisionsabout invasive specieshow we interact with the public andother partners when making thosedecisions and how those decisionsWatch at: 06:40 / 07:00might differ from other land managersthat might be on thewebinar today so this is our guidingprincipleand everything flows back flows fromthisso that means that in invasivespecies management and national parks umwe are are we are prioritizingWatch at: 07:00 / 07:20ecological integrity right so we'retrying to protect um theseecologically representative areas um butwhile we're doing that we have toconsideruh the needs of the public andhow their enjoyment and useof these places is going to be affectedWatch at: 07:20 / 07:40so weengage with indigenous partnersespecially and members of the publicwhen we're making decisionstake their views into account as best wecanand then what might differ from a lot ofpeople's experiencewe have much lower emphasis on economicWatch at: 07:40 / 08:00impactssay ergonomic impacts orpotential justmonetary impacts of invasive specieswhen we're deciding how to prioritizewhat we're going to control what we'renot going to trollthat being said we do try to be goodneighbors at the same time soWatch at: 08:00 / 08:20if uh neighboring land managers likehere thecolumbia shoe swap regional district isprioritizingcontrolling the spotted knapweed thatyou see there along the highwayin glacier national park which would bea low priorityfor us because it has relatively minimalWatch at: 08:20 / 08:40potential to spread into our deep darkinterior rainforestbut they have a high priority because itposes a risk to rangelandswell we're going to try to do our bestto control it to begood neighbors and then alsoin national parks we have to makespecial considerations for species atWatch at: 08:40 / 09:00riskum make many cases especially with rarespecies that with limited distributionsparks canada can actually be theresponsible agencyfor protectionum and pushing forward recovery plansfor individual species at riskand so when a pathogen or invasiveWatch at: 09:00 / 09:20fungus like in this casewhite nose syndrome affects a specialriskthat puts a special burden on us tomake sure that we're taking some actionto ameliorate thatso umWatch at: 09:20 / 09:40like i said we have a big system thatspansthe entire map the intention of parkscanada system is to be representativeof 39 different natural areas across thecountryand as a result the invasive speciesWatch at: 09:40 / 10:00issues that we faceare representative of the invasivespecies foundall across the country so we have a verywide and very diverserange of invasive species issuesthroughout our national park systemso we deal with things like pathogenshereWatch at: 10:00 / 10:20whirling disease that's establishedin banff national park other pathogenslike bovine tuberculosis which ispresent in riding mountain national parkwith buffalo national park bruce losesin with buffalo national parkum and some of these are very new likewhirling disease and some of them arebeen around for a long time like bovinetb uh weWatch at: 10:20 / 10:40deal with fungal pathogensum that can be really problematic inforest ecosystems like whitepine blister rust or butternut cankeragain it's threatening a species at riskor another fungalpathogen like brightpearl syndromecausing a bunch of species to become aWatch at: 10:40 / 11:00riskand then everybody's favorite insectfungi complexes like dutch elm diseaseuh beach bark disease that you see herethat's becoming a big issueuh in eastern parks uh or again thatbutternut canker which is a complexecologyWatch at: 11:00 / 11:20and then all kinds of animalsuh from very small little invertebratestothe biggest land mammals in most of thecountry soyou know everything from emerald youknow what you would expect to seeemerald ash borer mummyhemlock woolly adelgid becomingWatch at: 11:20 / 11:40problematic eastern parks zebra musselshave become a big issue riding mountainnational park uhrats are getting a lot of attention inum guayanasand then we have invasive moose innewfoundland that arecausing major ecological issues andWatch at: 11:40 / 12:00terra nova and grossmarnnational parks which i'll talk about alittle bit later onso we have a really wide range before weeven get to what i assume most peopleare here for which is the plants andwhich is my specialty soand here if i'm to do serviceum to the full range of issuesWatch at: 12:00 / 12:20seen across the country i can't justtalk about my favorites like smoothbraumi'm by favorite i mean least favorite umor the types of species that we'readdressing insome of the mountain parks like uh theknapweed that you saw earlier orhawkweeds or purple vetch in the case ofWatch at: 12:20 / 12:40mount rebel stokebut things like garlic mustard andjapanese knotweed that are quiteuh problematic in st lawrence valley andgreat lakes areas and out into themaritimesscotch broom that's an issue out on thewest coast and then purple loosestrifewhich everybodyknows and fears will end up in theirneck of the woodsWatch at: 12:40 / 13:00soin that way because we cover such a wideareawe kind of have a taste of all theissuesthat everybody else sees um in theirneck of the woodsuh throughout canada umWatch at: 13:00 / 13:20and that is great for us to be able tocollaborate with our partner with ourneighborsand learnfrom them and be able to provide supportto thembut in some important ways we are fairlydifferent from a lot of other landmanagersum looking to deal with invasive speciesWatch at: 13:20 / 13:40first off probably is the land use sofor i can't use any absolutes becausethere's always[Music]exceptions to the rule but generallythere's no agriculture in national parksthere's no cultivationforestry resource destruction all thoseWatch at: 13:40 / 14:00kinds ofum land uses that a umcan suffer especially in case ofagriculture from particular invasivespeciesand create priorities of particularinvasive species thatcause problems for those land uses butalsoWatch at: 14:00 / 14:20can umthe can perpetrate thoseuh the proliferation of those species byclearing land and opening bare soil andthose kinds of practicescertainly wasn't always the case uh formost national parks especially in thesouthern tierWatch at: 14:20 / 14:40uh that there was no extraction oragriculture happening within theirboundaries so we havea nice legacy of invasive species thatwere introduced throughcattle grazing or logging or mining orall kinds of previousuh past practices that are no longeroccurring national parksif you have a legacy but not necessarilypersisting pressure from thoseWatch at: 14:40 / 15:00land uses often timesnational parks protect rare species andecosystemscoastal dune systems inprince edward island or car systems inthe bruce peninsulaWatch at: 15:00 / 15:20southern grassland species in grasslandsnational parkthat aren't found broadly or at allin other parts of the park outside of orout other parts of the countryoutside of national parks um andoftentimes the species that are presenton thoserare sites or those rare species thatare contained within parks and notWatch at: 15:20 / 15:40found very often elsewhere can be reallythreatened by disruption of that smalllittlepocket of habitat by new invasivespecies moving insecondlywe have lots of visitors from all aroundthe world and from all acrossWatch at: 15:40 / 16:00north america all across canada comingto seethese amazing places and that's greatthat's part of our mandate topresent these places to those people butlots of people concentrated in smallareas umcoming from all over the place is agreat vectorfor seeds moving around on people'sWatch at: 16:00 / 16:19hiking shoesor people moving firewood around theback of their pickupand sometimes that can result innew invasive species popping up whereyou never thought they were for examplewhirling disease showing up inbanff in the middle of north northamerica before anywhere else uhWatch at: 16:19 / 16:40arriving from europe because there's ahigh degree of international trafficcoming into banff probablyum and now another thing that weprobablydeal with quite a bit thatother people might not have to uhWatch at: 16:40 / 17:00deal with as upfront or it might notbe as big a component of their programis thatthese sites umhave a lot ofthey have a lot of public umWatch at: 17:00 / 17:20love and sensitivity andpublic profileso when we're trying to usemethods especially chemical methodsor when we're considering eradicatingcertain species from islandsWatch at: 17:20 / 17:40say in haida gwaii there can be a lot ofpublic attention on thatissue and potentially public backlash sowe have to be very carefulin considering you know a broad range ofphilosophies aboutinvasive species control andWatch at: 17:40 / 18:00making sure we've done our eyes crossour t's make our best case to the publicas towhy what we're doing is necessary andwhythe methods that we've chosen are thebest availableokay so that's a lot of juststuff what about what's actuallyWatch at: 18:00 / 18:20happening soum the there's 23national parks that regularly monitorand port report on theimpact of invasive species uhin their park so that's pretty much allthe parks in the southern tier of thecountryexcludes most of the parks in the arcticor the near northWatch at: 18:20 / 18:40um and most of those parksum well i should explain allcanadian national parks on a program uhwhere wemonitor particular measures of ecosystemintegrity and on average parks that aremonitoringum invasive species in their or theirWatch at: 18:40 / 19:00indirect impacts onecosystem integrity uhare measuring well two differentincidences of thatwithin their park out of a total of 15different measures so it's apretty big chunk of what we think is athreat to the ecological integrityof national parksWatch at: 19:00 / 19:20and then you can see the numbers thereof those 45 different measuresacross the 23 parks about 17are in good condition 18 are faircondition eight are in poor conditionum and two aredata deficient we don't have enoughmonitoring data yet to be able to tellWatch at: 19:20 / 19:40you what that means souh for example here in mount revelstokenational park uh we have two measuresone which isthe abundance and distribution ofinvasive terrestrial plant species andthat'sin good condition right now and then wealso havea measure that measures the impact ofwhite pipe blister rust onWatch at: 19:40 / 20:00a white bark pine in the park and that'scurrently in fair conditionso there'll be similar assessments likethatacross most of the southern parts andthen you see below thatwe also measure whether that how thatcondition is changing across all theseWatch at: 20:00 / 20:20parts soonly we're only managing right now toget six to improve which is not a greatnumber but seven are stable and sevenare declining soagain similar mix across the topunfortunately we still have25 different measures like that that aredata deficient and part of that isa lot of these measures are new theseareWatch at: 20:20 / 20:40emerging pathogens or emerging emerginginvasive pests and we haven't had enoughtime yet to collect enough data to beable toestablish uh what the trend isfor that particular invasive specieswith a high degree of certainty sothat's why you see it reallyWatch at: 20:40 / 21:00um a lot of these uhother suites of invasive species orparticular invasive specieswe don't have a lot of data on yetso what are these all these pathogensand pests and invasive plants andanimals doingWatch at: 21:00 / 21:20in national parks so while i wascollecting all these numbersuh going through them last night there'sa couple things that really stick outso a big impact that we're seeingespeciallyin eastern canada is that we're havingseen a huge impact on tree healthWatch at: 21:20 / 21:40from pathogen fungal pathogens primarilyand then their associated insect vectorsso those are things like beech barkdisease dutch elm diseaseand then we're also seeing that out herein the mountain block with that whitekind blister rustthat's really having a big impact onWatch at: 21:40 / 22:00sub-alpine ecosystems and negativelyimpacting a foundational species thereum so also impacting forests arehyperabundant non-native ungulates so inthe picture there you see a black-taileddeer out onWatch at: 22:00 / 22:20haida gwaii where they'vebeen introduced without any naturalpredators andare completely defoliating andunderstanding understory anddramaticallyaltering the ecology of that systemuh completely removing justWatch at: 22:20 / 22:40absolute suites of understory vegetationreally having a big impact on smallmammals andsongbirds and then you see similarsituation out in newfoundlandwith um introduced loopsand their impact on forest regenerationandWatch at: 22:40 / 23:00gross more in turn over national parksthen you also seeespecially in the center of the countrybig impacts ongrassland biodiversity that was a bigfocus my work in riding mountainnational parkuh where invasive agronomic grasses andthen aggressiveforbs like canada thistle beefy spurgeWatch at: 23:00 / 23:20south thistle are really having a bigimpact on prairieparks and grassland ecosystems foundthere and then alsoin uh eastern side of the mountain blockparkswhere they have montane grasslands andthose arethose parks primarily issued concernedWatch at: 23:20 / 23:40with grassland biodiversity we also seeum right across the system impacts onwetland structure from emergent specieslikeuh phragmites and flareus andpurple lose strife where basicallywhat's happening is these areaggressive either aggressive invasiveWatch at: 23:40 / 24:00subspecies orfull species that are coming in andcrowding out native vegetationright across wetlands through the systemum and then we're also seeing threats tospecific speciesdue to pathogens so lots of pathogensum impacting vertebrate speciesWatch at: 24:00 / 24:20uh i mentioned already the umwhite uh white nose syndrome that'saffected a suite ofuh hibernating bats that is nowspreading eastern through canada'sboundaries somewhere around saskatchewanright now umso those are those are probably the mostWatch at: 24:20 / 24:40common impacts they're going to beseeing if you talk to mycounterparts in other national parksthroughout canadaso i can give you some more specificexamplesuh so we talked briefly about gross mornso uh just over a hundred years agoWatch at: 24:40 / 25:00moose were introduced um along withsnowshoe hairto newfoundlandwhere they had previously not beenpresent right around the same timemanaged to extirpate wolves from theisland so then we'll the moose didn'thave any natural predatorsand then we protected those moose insideWatch at: 25:00 / 25:20ofnational parks where people weren'tallowed hunt and surprise surprise thepopulation explodedand then they did what you see on thebottom there turna beautiful maturefur forest into kind of a broken downmoose meadow moose pasture umWatch at: 25:20 / 25:40and this is having huge whole ecosystemimpacts whereum forest regenerationand tree recruitment simply isn'thappeningespecially in balsam firand deciduous speciesthey're just not able to surviveWatch at: 25:40 / 26:00the level of moose orbit herbivorythat's being seen on thatin those sites and you can see therewith the exclosurewhat would be happening if the moosewere absenton one side of the fence and then whatis happening with most presenton the other side offense and this isobviously by modifying the entireecosystemWatch at: 26:00 / 26:20affecting pretty much every organismin that community sothis is a big big issue that needs to beaddressed um but it's complex because itum in order to addressmoose overpopulation we have toWatch at: 26:20 / 26:40uh coordinate with the government innewfoundland labradorand has ultimately resulted inbig game hunting being allowed withinterreno and grossmore national parksthrough the provincial big gaminglicense systemWatch at: 26:40 / 27:00in order to decrease the population movesirum and any of these examples that i'mgoing through i'm happy toeither answer questions the best myabilityuh at the end or point in the rightdirection thethe person that knows way more aboutthis than me so from guayanasWatch at: 27:00 / 27:20uh the national park at the southern tipof paraguayseveral problematic invasive species butone where we've had a lot of success isaddressing the effect of black ratson sea seabird colonies thatWatch at: 27:20 / 27:40are present or at least should bepresenton islets aroundthe main island so we had a majorproject theenglish name there is nightbirdreturning i'm not going to try the haidathis was project to use poisonsWatch at: 27:40 / 28:00to eradicate black rats from a series ofislandsin the hopes of allowingancient muralits to recoverfrom nest predation by those rats andwe've had really good success on severalislandsrecently there was brown rats discoveredWatch at: 28:00 / 28:20after these islands were discovereddeclaredblack brown rat free and that's in partbecause these islands are quite closeum to the mainlandum and there's mammals that are able toswim that distanceuh but this is something where we have aWatch at: 28:20 / 28:40reallyimmediate impact um we can have reallygood positive resultsuh with populations ofthese shortness of these seabirds umlike ancient muralits and other mirrorspeciesum rebounding really quickly but it'sWatch at: 28:40 / 29:00alsoan example of where you need localbuy-in there'sthere can there's been situations withsimilar attempts at rad eradicationthat have gotten a lot of negativepublic feedbackbut luckily here we had the support andum teamwork of uhWatch at: 29:00 / 29:20hiatu nation uh archipelago dirt uhstewardship committee i think if i'mright but if there's anybody from haidacorrect me on the name of thatorganizationum so here mount rebel silicon glacieri'll try to go quickWatch at: 29:20 / 29:40i can kind of talk you through how weaddress the impacts of invasive speciesinmy backyard sowe manage both parks together well rebelstoke and glacier together with about1300 square kilometers inmountains ecosystem uh so it's anWatch at: 29:40 / 30:00interior rainforest high vel highelevation system for the most part[Music]we have 103 vascular plant species thathave been identifiedin the park we don't have a ton ofnon-nativeWatch at: 30:00 / 30:20fungal pathogens or other pathogensthat we have to worry about other thanwhite pine bliss for us whichis not my specialty so i'll leave thatto the experts for another dayand here i'll just talk about vascularplantsin these two parks soWatch at: 30:20 / 30:40being in the columbia mountains we havesome natural advantagesuh in our attempt tolimit the ecological impact of theseintroduced species so one is that we geta lot of snowum several meters umWatch at: 30:40 / 31:00as a consolidated pack by the end of thespring up to you knowfive meters umwhich really creates a pretty finesfor speed species to be able to passthrough and establishin the zika system and then uh on theother handWatch at: 31:00 / 31:20a really dense canopyof western hemlock and red cedar uh isalso ajust wonderful uh cultural control onmost of these species soit's a really shady snowy environment umdoes wonders forlimiting the impact of these 103 speciesWatch at: 31:20 / 31:40that we've identified throughout theparkthat being said there are environmentsin the park outside of that shadyrainforest so most of our work focuseson thesevulnerable habitats that are for themost partWatch at: 31:40 / 32:00sunny and disturbed or eithersunny and or disturbance prone so we'relooking at alpine and sub-alpine meadowsavalanche paths that get readily scrapedclean when we have a big avalanche cycleandwetlands that have lots of sunand nutrients and water and all theWatch at: 32:00 / 32:20other kind of things that uh weedyspecies like to gobble upsoeven though we do have a lot ofadvantages and being up high with lotsof shade and snowin keeping invasive species out we alsohave some challengesone is that both parks sit on a majorWatch at: 32:20 / 32:39transportation corridorthat serves as great vector for invasivespecies jumping offfrom all over the country the cp lineand the transcanada highwaywe have really excellent access forvisitorsover i think it's close to 800 000Watch at: 32:39 / 33:00visitors a yearright into our cell bellbine and alpinemeadows whichare probably the most vulnerableecosystem that we have so we have themedicine sky parkway that goes right upto the top of mount revelstokefrom town and people can stay out ofWatch at: 33:00 / 33:20their cars into thosenice open sunny subu pine meadowsand we've got lots of trails that gostraight up from the transgender highwayto the top of the alpine in glaciernational parkand then we also have an active fireprogramand other parks operations thatWatch at: 33:20 / 33:39inevitably result in helicopters andequipmentand gear and people flying directly fromthe side of the trans-canada highway orparking lot nearbythat might be covered in invasivespecies thatcan't really keep out due to the levelof disturbance along theWatch at: 33:39 / 34:00highway edge where there's a big seedsource and then going directlyinto uh vulnerable alpine ecosystems sothis picture on the side here is fromglacier circle which is one of the mostbeautiful remote gorgeoussites in glacier national park withreally low impactWatch at: 34:00 / 34:20really low visitation but we found patchof yellow hawkweed right at the skid ofthat helicopterthat must have been established the yearprior while they were doing work on thecabinso clearly the helicopter landed in thesame spot last year and somebodyWatch at: 34:20 / 34:40stepped out and had a few hot weed seedsin the bootand plants got established and that'sprobably 20 kilometers from the nearestpopulationmaybe if you go by uh by footor by bike it would have been a 30kilometer tripWatch at: 34:40 / 35:00uh so we're constantly having problemswith vectors into thesevulnerable habitats so how do we dealwith thatum we use integrated pest managementlikeall good pest managers dowe work on a system where we try to keeparolling program where we plan ourWatch at: 35:00 / 35:20approach for the year and then weundergo some surveillance figure outwhere the problem is prioritize which ofthose issues we're going to deal withundertake our operations our currentcontroller treatmentsand then monitor whether those areeffective on the short term and onWatch at: 35:20 / 35:40medium term and then we reassess thoseresultsand go back to the drawing report goback to thebeginning prioritizing based on thosethe results of thosemonitoring studies so that all getsrolled intothis this is our uh invasive alien plantmanagement planWatch at: 35:40 / 36:00um update this everyuh five years as part of thatreassessmentum so i'm just in the processing now ofupdating for2021 umand then hopefully we'll have thatplanning out of the way next spring andthen we can go out andWatch at: 36:00 / 36:20get back to surveillance so oursurveillance program kind of takestwo twoapproaches one is early detection rapidresponse especiallyalong the highway corridor where we knowwe are going to getuh the first occurrences of any speciesWatch at: 36:20 / 36:40that werelikely to have become established in theparkso keeping an eye out when we're movingalong the transportation corridorson roads easily accessible roads to seeif there's any new species popping upwe've got a good crew that's trained upwelland they've always got their eye peeled[Music]and then we also do periodic uh siteWatch at: 36:40 / 37:00surveys sosurvey pretty much the entire park umall those try to get all those littlered lines at trailsyou see they're surveyed once every fiveyears and identifyany populations we find there that waywe can identify whetherWatch at: 37:00 / 37:20populations of individual species aremoving advancingpopulations are appearing ordisappearing as a result of that we havea very very complexcomprehensive database of allof those uh just over 100 speciespresent park so we haveover or just under 8 000 recordsWatch at: 37:20 / 37:40of individual species sitesand then we can prioritize themin order because we're not going to idid say we have awell-trained uh highly capable crew butthey're not going to getto just under 8 000 sites in a year soWatch at: 37:40 / 38:00we have to kind of prioritizehow we spend our money and umwe base that on first a speciesprioritization one that's based onranking thatsue makowski did for most western parksback in 2007but then we also include updated inputWatch at: 38:00 / 38:20fromthe columbia shoe swap invasive speciessociety a regionalinvasive species society's priority listand that helps us to rank into thesedifferent priority levelsand we're currently working on updatefurther updates to thatranking system that will include shadeWatch at: 38:20 / 38:40toleranceand elevation tolerance so that we'rebetter able tofine-tune our control effortsto species that we think are going to bemore problematicand more likely to invadesensitive ecosystems and there you cansee thethose are all our very high and highWatch at: 38:40 / 39:00priority specieson the right thereum and then we also prioritizewhere we're going to do our control bysite solooking at which of those systems aresensitive to invasion in the greenin the map on your right there um soWatch at: 39:00 / 39:20sub-optimum meadow slide paths wetlandsum even rocky outcrops with low canopycover of forestplaces where it's relatively easy forredural species that arelight hungry to become establishedwe also consider whether they areWatch at: 39:20 / 39:40likely to be in proximity toin vectors of invasionlike the transportation quarters likehiking trails likeparks operations umand then we use that to build this mapofpriority zones where our approach toWatch at: 39:40 / 40:00addressing a particular invasive speciespopulation will depend on what zone itis inthat being said we will still be a goodneighbor and even ifmaybe a particular population doesn'tcome outsuper high on our list priorities andthat's maybe in a lower priority zonefor us but we know thatWatch at: 40:00 / 40:20the columbia should show up in racespecies society orthe town of golden or the town of rebelstill because really making that speciesa prioritywill make it a priority for ourselves aswellokay so then once that's all puttogetheri have an excellent crew of two techsand two students thatspend the bulk of the summer working oninvasive species controlWatch at: 40:20 / 40:40and that includes a lot of hand pullingup onuh steep steep mountain trails that'shard to getequipment into uh we've got this funkything called the steam leader that we'reable toeffectively fairly effectively uhcontrol shallow-rooted species in areasthat would be otherwise sensitive forWatch at: 40:40 / 41:00due to public opinionor just ecological sensitivities likeareas near water we're able to use thatinstead of using chemical controlbut we also do a fairly extensivechemical control programWatch at: 41:00 / 41:20that we contract outgenerally and then we have the columbiashoe shop invasive species societyhelp us out with the monitoring for thatchemical control programthat's mostly concentrated around areaswhere we haverelatively large populations close tothe transportationWatch at: 41:20 / 41:40quarter that we still want to work onthis year we actually had some reallypromising successyou might have noticed that i am veryconscious ofum public opinion and potential publicbacklashuh for invasive species work withWatch at: 41:40 / 42:00especially withchemical control in high priceful highprofile areasand if anybody has questions about thati'd be happy tospeak to my experience on that but uhthis year we worked in areally high profile area the ver thesummitof mount revelstoke the top of theWatch at: 42:00 / 42:20medicine sky parkway which isreally high use tourist area people gothere to see wildflowers they don't wantto see dead plantswhen they step out of the parking lotbut we have a really big populationan aggressive population of purple vetchat the summit thereand this summer we were able to use umWatch at: 42:20 / 42:40a wicking treatment uh using glyphosatein that areaum we just kind of experimentallytreated a few patches andto see one would they be effective withthisnew treatment that we're trying to beeffective but then alsowhat kind of public feedback would wegetWatch at: 42:40 / 43:00when all the signage goes up and theuh no entry areas go because uh chemicaluseuh and we got nothing other than eitherpublic interest or positive feedback orjust curiosity which isreally promising to see that maybe ouruhwe're building moreWatch at: 43:00 / 43:20support in the community and with ourvisitor base forour program uh and with that i will sayi'm happy to open up to any questionsgreat thank you peter for that awesomepresentation so we do have a fewWatch at: 43:20 / 43:40questions and peter i'll just get you tostop sharing your screen and thenthey'll be able to see both of uson camera okay there you goawesome thank you so our first questionwas from johnand he's wondering if there are anynational parks that allowWatch at: 43:40 / 44:00cohabitation wolves and humanssorry can you cohabitation with wolvesand humansyes yeah that's correct uhwell um i'm not 100 sure that iunderstand that but there'sWatch at: 44:00 / 44:20uh lots of the national parks uh havewolf populationsi would have to say most do andthey all um allow some degree of publicaccessfor sure the camping hiking all thatkind of stuff and then actuallya number of parks with wolf populationsWatch at: 44:20 / 44:40i guessif this is what you mean by cohabitatinglike banff jasperprince albert riding mountain yoho allhave smalltown sites on them that haveseasonal or permanent populations ofsome size but peopleWatch at: 44:40 / 45:00great thanks peter and i see john put alittle comment there in the chathe said what is meant is why not let thewolves come back for the moose tocontrol themah so in uh newfoundland umthat's a complex issue because umWatch at: 45:00 / 45:20it is it well it is true that wolveswere excavated from irelanduh the ungulates uhi think one there's probably someconcern from the widerpopulation newfoundland aboutreintroducing wolves uh there's quite alot of excitement just about coyotesshowing up right nowbut also there would be concern aboutWatch at: 45:20 / 45:40wolves not wanting to eat moose or getkicked in the head by a big moussainstead predating on the native caribouthat are thereand potentially uhcreating a dynamic where moosepopulations subsidize wolves that justend upeating all the caribou so they're that'sWatch at: 45:40 / 46:00a trickyuh dance to play and i don't think it'llbe addressed anytime soonand then our next question from aaronum we can find the machelsky 2007document that you referred to in thepresentationWatch at: 46:00 / 46:20um you know what idon't know if there is a publiclyavailable uh version of that documenti can certainly i could see if we haveitand i can forward links there are idon't have it on me right now but thoughwe're trying to make uh do a better jobWatch at: 46:20 / 46:40of making ourkind of gray literature and great datauh publicly available um and that'ssomething thateach park independently wasuh provided a report so i have thereportfor mount revelstoke and glaciernational parksWatch at: 46:40 / 47:00and he i think almost every park inwestern canada has a similar reportbut i can um if you're interested inthat rebel so glacier one i can provideit to youi just shoot you an email or if you'reinterested in any of the other parts ican provide to youokay and then jane had a questionWatch at: 47:00 / 47:20wondering how many staff do you havededicated to weed management and youuse volunteersso we don't have um we havewithin uh mount royal sloka and glaciernational parksuh our vegetation program hasuh seven staff totals so we haveWatch at: 47:20 / 47:40three year-round staff my supervisormyself and a staff member that's focusedon a whitebark pineproject and then we have four seasonalstaff two technicians and two studentsumand while myself the techs and theWatch at: 47:40 / 48:00studentsprobably spend most of our time dealingwith invasive speciesthat's not necessarily the caseeverybody kind of gets bounced aroundsometimes if we're dealing with fire orwildlifeor other vegetation issues but i wouldsay probablyyou know there's maybe five of us that75 percent of our timesinvasive speciesWatch at: 48:00 / 48:20and then we had a question come in overfacebookum there's a viewer wondering if whitepine blister rust is an invasive speciesor justum just more related to forest health ingeneralso white pine blister rust myWatch at: 48:20 / 48:40understanding isit was um it's long established in northamerica it's been around for quite awhileum and has been problematic in thepineriesof eastern western north americaespecially in theeastern white pine west white pine butit originated ineurasia and has nowWatch at: 48:40 / 49:00migrated from those white pines to theother five needle pines so white parkpineand limburpine here in north america andfor the most we're seeing very very lowlevels of disease resistance in thewhitebark pinein these two parks hereWatch at: 49:00 / 49:20thanks and robert has a question um areyou doing any canary grass control foraquatic ecosystemsuh so we don't do any re-canary grasscontrol herein monroe silk and glacier uh let meWatch at: 49:20 / 49:40lookat i think there are uh parks that aredealing with it i know it's challengingespecially because thethey're in most north america there's anative subspeciesum that's really hard to differentiatefrom the invasive species otherinvasive duration subspecies other thanthat it's not invasiveWatch at: 49:40 / 50:00but i've gotten my notes here somewherethe parks that areactually doing i think elk island is uhdealing with it and theni want to say prince edward islandnational park or fundy butit's one of those problems wheregrasses often don't get the attentionthey deserve especiallyWatch at: 50:00 / 50:20um when there'sit's not creating necessarily agrassland ecosystem if it's just kind ofa marginal open ecosystemoften doesn't get as much attention butumi could certainly say that there's ahuge problem with itin in and around monroe folk but luckilyWatch at: 50:20 / 50:40we don't have a lot ofwetlands that have been affected by itgreat thanks peter i also find too ifyou don't really knowlike you're looking for in grasses theycan be hard to id whereas like mostpeople know like oh that's spottednapweed and then they see it and theyreportWatch at: 50:40 / 51:00it right away so it's easier to to knowwhere it occursbut i would absolutely encourageeverybody to dive into the wonderfulworld of grasses ii fully enjoyed my time riding mynational park to know uh the nativegrasses thereand once you know the natives it'sreally easy to pick uppick out the invasivesWatch at: 51:00 / 51:20that's great yeah that's something ineed to to brush on more for sureanother question from aaron i know thatyohoand kootenai implemented a requirementfor watercraft users to self-certifyclean drain dry this yeardo you have any information on how thatWatch at: 51:20 / 51:40wentum you know what i had ai was in a meeting with my counterpartin yoho and kootenayum a couple of weeks ago and i'm justtrying to remember what he said aboutthatum it seemed likeWatch at: 51:40 / 52:00it occurred relatively without issue ithinkthey benefit from bc having a reallyrigorous programright at the border to begin withand there's a parks canada now has areally rigorousuh program that they can move into newWatch at: 52:00 / 52:20parks aszebra mussels especially kind of movenorth and westthat was developed in rioting mountainumso you know i don't have any specificinformation for you but i can find outfor youbut for might i know that it didn'tWatch at: 52:20 / 52:40sound like there was much of an issuewith implementing itgreat thanks peter we can always findout more information tooand send it out in an email as well andthen we do have uh one last questionhereand this one's from emily soWatch at: 52:40 / 53:00from your perspective do you think thevisitors of the parks could be betterleveraged to assist in the management ofinvasive speciesand if so how do you feel they could beutilized toincrease progress towards improvingstrategic andexcellent excellent question number oneWatch at: 53:00 / 53:20i naturalist i think i naturalistgreat and everybody that's coming intothe parkshould be told you have a phone in yourpocket put eye naturals on it it's freewe'll tell you what plants you see we'lltell you what birds you see uhi try to be pretty good aboutuh just in my personal life being on aWatch at: 53:20 / 53:40naturalist and trying to id stuff forpeople as it comes inuh but you know for the most part it'sjust going to begarden variety i saw you isub alpine fur i saw a western anemonebut for every 100 one of thoseWatch at: 53:40 / 54:00you know native common species that weidentify somebody'sthere's way more people spending waymore time uhout in the park than we could ever fieldum with our staffand some of those people are gonna seenew invasive species popping up at thepark before we do and if we can get themtoWatch at: 54:00 / 54:20put that data onto an app oronline or report it somehow get peopleand even just get people you know tostartlooking past their plant blindness andstart to realize that oh all this greenstuffit's different from itself and can beidentifiedthat would be great umWatch at: 54:20 / 54:40and we're starting to just make a pushfor that througha bunch of western parks uh that's we'retrying to coordinate through this thingum so i think that would do wonders evento justuh inform people umrap also is great um i thinkWatch at: 54:40 / 55:00i think the nice thing about inatus isthat umwe get really immediate feedback andit's umjust really user friendly for people ontheir phonesthen alsodidn't really get to do it this year buti'd love to have more volunteerWatch at: 55:00 / 55:20days to come out and do weed pullshoping to address some big issues withthe purple vetch that i mentioned onmount revelstoke and then probably alsouh norway maple on the lower slope ofmount rebel stoke sohopefully when uh the pandemic is overwe can have more people out to do weedpolesand then also trying to get people toWatch at: 55:20 / 55:40reduce their own impactum hopefully next year installing bootbrushes at all as many trailheads as wecanand getting people to kind ofself-regulate make sure they'regoing into the bush with clean gear andnotallowing themselves to be a vector forinvasive speciesWatch at: 55:40 / 56:00thanks peter yeah i really enjoy using inaturalist and i alsouse sport invasives app a lot as well sothat's a great onewhere you can report in bases that yousee or even if you just want to look uppictures to see what you're looking atthat one's a good one to use as wellalso i just want to say a big thank youWatch at: 56:00 / 56:20on behalf of
