Media coverage of invasivesMedia coverage of invasivesMedia coverage of invasivesMedia coverage of invasivesMedia coverage of invasivesThis issue of Cal-IPC News is full of tidbits from the mainstream media. Though “any newsis good news,” we are always curious to see if news reports on invasives will “get it right.”Increasingly, we are seeing articles by knowledgeable journalists with a high degree ofunderstanding for the issue. A recent article in the San Francisco Chronicle did an excellentjob of describing the goals and strategies of the Coastal Conservancy’s efforts to rid SF Bay ofSpartina alterniflora hybrids.

When an article fails, it sometimes does so spectacularly. Such was the case with the LosAngeles Times piece extolling the virtue of giant cardoon (Cynara cardunculus) as a gardenplant. Such pieces are entertaining in aneye-rolling way, but they show the needfor continued outreach. As materials likethe Don’t Plant a Pest! brochures reachmore gardeners, awareness of invasivenessas an important factor will grow. We expectinvasives will become even more commonin the news, and plan to take advantage ofthis opportunity for education.

As we do each year at this time, wewelcome five new board members.Goodbye and a big “thank you!” to JoeDiTomaso, Alison Stanton, Carri Pirosko,Jon Fox, and Bobbi Simpson.

The U.S. Senate Committee on Commerce,Science, and Transportation voted unani-mously to approve the "Ballast WaterManagement Act of 2005" (S. 363),introduced by Sen. Daniel Inouye (D-Hawaii)The bill now moves to the full Senate forconsideration. Unfortunately, according to theUnion of Concerned Scientists, the billshould be scrapped in favor of S.770 (Levin,D-Michigan), which would more fullyreauthorize the Nonindigenous AquaticNuisance Prevention and Control Act of1990. S.363 would focus only on ballastwater, delay implementation, and loosen

Four states sued the U.S. Department ofAgriculture in September for failing to imposeeffective controls against destructive insectsthat enter the country in shipping pallets andother wooden packaging.

New York, California,Connecticut and Illinois filed the lawsuit,which seeks a court order directing USDA to

find more effective and less environmentallyharmful methods of preventing the insectsfrom entering the country. (9/15/05)<www.oag.state.ny.us/press/2005/sep/sep15b_05.html>

Ever-increasing transport of species of allkinds is breaking down biogeographicalboundaries with profound conse-quences for biodiversity lossworldwide (Vitousek et al. 1997,Mooney and Hobbs 2000). Whenspecies are transported—intention-ally or inadvertently—outside theiroriginal geographic ranges, many ofthem become established andspread. Some proliferate explosively,tending to displace native species intheir new area of establishment.Evolving technology (e.g., shippingcontainers) has increased shippingspeeds and volumes, making ourdetection and interception strategiesfor stemming the flow of invasivesin the United States very difficult toimplement and certainly inadequate(Campbell 2001, Loope andHowarth 2003).

Given the seeds of catastrophicloss already planted and those yet tocome, invasive species pose a highlysignificant threat to the biodiversityof the U.S. National Park System inthe early decades of the 21st century(e.g. Wilcove et al. 1998). Moreover,global climate change is likely toexacerbate the problem by favoringinvasive nonnative species overnative species (Mooney and Hobbs2000). Writing as a former (24years) employee of the National ParkService, now with the U.S. Geological Survey(USGS), my attempt here is at a personalreview and synthesis of implications of trendsin biological invasions for national parks,based on personal experience and analyses byothers.

Who will prevent and combat invasions?Invasive plants comprise a highly visible

taxonomic group among many seriousbiological invaders permeating the UnitedStates and reaching even the relatively isolatedand intact ecosystems of the national parks.Federal natural resource managers can

potentially address invasive species issues inconjunction with local outreach efforts,working with agencies (federal, state, andlocal) and individuals in communitiessurrounding the parks and refuges foreducation, prevention, detection, and rapidresponse.

An NPS workshop in Ft. Collins,Colorado, 4-6 June 2002, in which Iparticipated, produced useful guidelines formonitoring invasive plants in and near thenational parks (Hiebert et al. 2002). Notewor-thy innovations of the guidelines include theneed to “work outside of park boundaries to

manage at a landscape scale … [and]identify a buffer zone, which, whenadequately managed in cooperationwith partners, will more effectivelyaccomplish invasive species manage-ment goals.” Yet, although increasingattention is being given by public andprivate entities to the need forcontrolling plant invasions, almost nobarriers to the movement of plantspecies by humans throughout theworld exist, including the UnitedStates. Approximately 20,000 speciesof vascular plants have proved invasiveand damaging somewhere in theworld (Randall 2002). U.S. federalnoxious weed law (APHIS 2000)currently prohibits 91 species and fivegenera, most of which are well-documented threats to agriculture.

Other taxonomic groups besidesvascular plants pose present and evengreater future threats to park ecosys-tems. Insects and fungal diseases thatattack trees are probably the mostimportant groups nationwide. TheForest Service began working with theAnimal and Plant Health InspectionService (APHIS) of the U.S. Depart-ment of Agriculture (USDA) in thelate 1980s to address invasive speciesthreats associated with raw woodimports and solid-wood packaging

materials (e.g. Tkacz et al. 1998). Neverthe-less, Thomas Hofacker (staff entomologist,USDA Forest Service) sees forest health in theUnited States as broadly declining, with threeto five new problematic insects or pathogensbecoming established in this country eachyear, and with many tree species becoming

“functionally extinct” (presentation at annualmeeting of Entomological Society of America,San Diego, CA, December, 2001). Campbell(2001) believes this situation is at least partlybecause the international system for regulatingtrade to prevent transport of potentiallyharmful organisms places a huge burden ofproof on countries wanting to protect theirecosystems from pests arriving through suchpathways as raw wood and wood packingmaterials. Another important point is that thenational and international quarantine systemwas designed to protect mainstream agricul-ture with little or no reference to the protec-tion of natural areas from biological invasions(Campbell 2001, Baskin 2002).

In the United States, the agencyprimarily responsible for protecting ournation's borders from biological invasions wasuntil recently USDA-APHIS. Because ofgrowing recognition of the need to addressthis problem (e.g. the threat to forests ofinsects and diseases in raw wood and woodpackaging material) and others, APHIS hadbegun to focus beyond its primary mandateof protecting mainstream American agricul-ture. Most of the large branch of APHISresponsible for protecting our borders frombiological invasions at U.S. ports of entry(Plant Protection and Quarantine) wastransferred to the Department of HomelandSecurity (DHS) in March 2003. How thismove to a different government departmentwith a different mandate will affect theprotection of natural areas and biodiversity isnot clear.

A 1993 report by the CongressionalOffice of Technology Assessment recognizedmany challenges the existing system faces tokeep harmful nonindigenous species out ofthe United States (OTA 1993). For example,first-class mail within this country is a virtuallyunaddressed major pathway for transport ofbiological material (potentially, for example,federal noxious weeds), protected against“unreasonable searches” by the FourthAmendment to the U.S. Constitution (OTA1993, p. 48-49). This is just one of manycases cited in the OTA report in which thecurrent system gives invaders the edge.

Since publication of the OTA report,international treaties to facilitate the workingsof the multilateral trading system haveevolved (Werksman 2004). After years oftrade negotiations, the World Trade Organiza-tion was established in 1995 and with it atreaty on sanitary and phytosanitary measures(FAO 2004). The treaty is managed by the

Food and Agriculture Organi-zation of the United Nations,which is responsible forimplementing the Interna-tional Plant ProtectionConvention. Some of thetrade-promotion measures havenot benefited invasive speciesprevention. For example,countries cannot legallyexclude a potential pest incommerce unless they canclearly establish that a specific,credible threat exists through arisk-assessment process.Moreover, a country canrequire only the minimumtreatment measures docu-mented as effective in reducingrisk. On the positive side, it canbe said that the internationalsystem has responded well to the threat ofmovement of pests in solid-wood packagingmaterial and has produced largely excellentguidelines for regulating this pathway (FAO2002).

Biological asymmetry and invasionsNot all regions of the world are equally

susceptible to biological invasions; someregions primarily seem to be source areas.Called biogeographic asymmetry, thisphenomenon has been widely recognized inmarine and aquatic invasions (Vermeij 1991,Lodge 1993) although it is just as prevalent interrestrial invasions. North American forestsare particularly vulnerable to invasions ofEuropean and Asian insects (North AmericanForest Commission 2000). Many more plant-eating forest insects from Europe havesuccessfully invaded North America (approxi-mately 300) than have invaded Europe fromNorth America (34) (Nemiela and Mattson1996). The decline of forest species of easternNorth America caused by insects andpathogens, mainly from Asia (Campbell andSchlarbaum 2002), does not seem to be areciprocal phenomenon. Very few nativeinsects and diseases of North America areknown to have become established in Asianforests.

Hawaii—the U.S. region most susceptible tobiological invasions

Oceanic islands are well known to beespecially vulnerable to invasive species. TheHawaiian Islands comprise one of the mostisolated island groups in the world, with

biological endemism at the species levelapproaching 100% for many native groups.Over all, Hawaii has approximately 10,000endemic species (found nowhere else on Earthbesides Hawaii), out of a total biota ofapproximately 20,000 native species(Eldredge and Evenhuis 2003). Hawaii , withfar above-average vulnerability to invasions(Loope and Mueller-Dombois 1989), is also amajor international hub of commerce. It is byfar the U.S. region most damaged byinvasions, with large numbers of and seriousimpacts from invasive vertebrates, inverte-brates, and flowering plants (e.g. Loope1998).

Nevertheless, Hawaii receives no specialprotection to prevent invasive speciesintroductions. Border protection from foreignpassengers’ baggage and cargo at the Port ofHonolulu is essentially identical to that at allother international ports in the United States(CFR, Chapter 7, 319.56-8). Preventiveactions are taken based primarily on anapproved list of organisms for which specificlegal authority is deemed to exist (JamesKosciuk, Agriculture Liaison, Customs andBorder Protection, DHS, Honolulu , Hawaii ,personal communication, May 2004).Moreover, although Hawaii has better laws forpreventing invasive species establishment thanmost states (OTA 1993), the Hawaii Depart-ment of Agriculture has little or no authorityfor protection from pests from foreign sourcesand receives limited funding (HDOA 2002).USDA-APHIS has a large program based inHawaii for airport departure inspections to

The destructive Asian longhorned beetle (Anoplophoraglabripennis) from China provided a wake-up call regardingthe threat of solid-wood packaging material as a majorpathway for invasive pests into the United States.

Local groups around the state organizedweed events for the third annual CaliforniaInvasive Weeds Awareness Week, July 18-23.The California Invasive Weeds AwarenessCoalition (CALIWAC), of which Cal-IPC is amember, provided a guide to organizingevents to help spur local groups to developevents.

Some highlights included: Friends ofFive Creeks (www.f5creeks.org) in AlamedaCounty removed invasives along a section ofcreek that was recently opened to publicaccess. In Santa Cruz County, voluneersremoved Ammophila arenaria (Europeanbeach grass) from dunes. Park staff and a crewof Student Conservation Association workersRedwoods National Park gave presentations atthe park visitor’s center and led a walk with aninvasive plant removal work party. They evenlanding a front page story in the Del NorteDaily Triplicate (www.triplicate.com/news/story.cfm?story_no=1826). The Tahoe BasinWeed Management Area held a “Broom

Sweep,” in which residents could turn in aScotch broom plant and receive a non-invasive alternative for their garden. TheLassen Special Weed Action Team (SWAT)held a booth at the county fair. Otherprograms ranged from training sessions forMaster Gardeners to displays of local invasiveweeds at county administration buildings andcommunity colleges. Cal-IPC received amention in a Riverside Press-Enterprise article

that described the threat of invasive plants inthe desert and their role in increasing firedanger in southern California.

The challenge for CIWAW 2006 will beto improve publicity and participation by thepublic. Ideally, the program could grow tosomething resembling Coastal Clean-UpDay, with a statewide campaign. While manygroups organized events, the comments wereceived afterward included, “unfortunately,we were not able to more widely advertise theevent,” “small turnout of seven volunteers,”“the publicity was not very good, so no onefrom the general public attended,” and “onlyone person brought in a broom plant.”CALIWAC has developed a guide toorganizing and publicizing events. Althoughwritten for Weeds Awareness Week, itcontains information that local groups canuse throughout the year to raise their profilein the community. It’s available on ourwebsite at www.cal-ipc.org/for_land_managersor contact Cal-IPC for a copy.

Sierra SummitSierra SummitSierra SummitSierra SummitSierra SummitCal-IPC displayed an exhibit at the

Sierra Summit in San Francisco, Sept. 8-11,the first-ever national conference of SierraClub members, with 4000 attendees from

The display drew asteady stream of visitors, most ofwhom seemed at least somewhatfamiliar with the issue of invasiveplants. The Sierra Club has notmade invasive species a focus of itsprograms, although it doesrecognize the problem andfeatured an article on tamariskremoval in Sierra magazine last year.

The “legacy project”during the conferencetook Sierra Club members to Golden GateNational Recreation Area to remove cape ivyand other invasives. A few attendees paidnearly $400 for a post-conference field trip topull invasive weeds for a week at Pt.

As partof our community outreach efforts, wethought it would be fun, as well as aneducational tool, to do our part to controlinvasive plants by eating them! This years’lecture was given by Doug Gibson, Directorof the San Elijo Lagoon Conservancy andmanager of a grant to the Carlsbad WatershedNetwork for invasive plant removal through-out north San Diego County. A guided hikeinto the adjacent native habitat afforded theguests a first hand look at the pampas grassand arundo removal efforts, as well as aremarkable array of native species. The picnicluncheon featured food made with invasiveand non-native plants. The delicious menuitems included nasturtium butter, ice plantpickles, Fennel and fruit salad and a stir frywith black mustard and artichoke thistle stalks.The guests had a wonderful time learningabout, seeing and eating invasive plants!

The 7th Annual CaliforniaWeed ManagementArea (WMA) Statewide Meeting was held onSeptember 19-20 at the Heidrick AgriculturalHistory Center in Woodland. This meetingprovides the opportunity for WMA coordina-tors, stakeholders, and other interested partiesto come together and share experiences, ideas,frustrations and successes. Eighty peopleparticipated this year. The conference featuredspeakers on grants and funding, includingtalks on the California Invasive Weed Aware-ness Coalition's (CALIWAC) push forfunding and how to spice up grant applica-tions for weed control. We also heard updateson The Nature Conservancy's Weed Informa-tion Management System (WIMS) and howto identify some rare A-rated noxious weeds.Regional breakout groups discussed local weedprograms and exchanged information onproven techniques and funding sources. Theevent concluded with a talk by Joe DiTomaso,UC Davis, on effective treatments and newcontrols. The WMAs had the opportunity toshow off their educational displays, along withproduct exhibits.

On September 21, the UC DavisBiological Invasions Integrative GraduateEducation and Research Traineeship (IGERT)program hosted a workshop called, “Gardens& Guppies: Working together to preventintroductions of invasive species via thehorticulture and aquarium trades.” Theworkshop provided a forum for leadingacademics, industry representatives, NGO

staff, agency personnel, andstudents to discuss the issues ofinvasive species relating to thenursery and aquarium trades.

The IGERT trainees, graduatestudents from a variety of disci-plines, organized the symposium as aculmination of their second yeargroup project. The theme of theproject focused on imports ofpotentially invasive species by theaquarium trade and the potential forself-regulation by the horticulturetrade. The students presented theresults of their project along withspeakers from the University ofWashington, Ecos Systems Institute,Sustainable Conservation, and thePet Industry Joint Advisory Council.In the afternoon, attendees separatedinto two groups for more in depth discussionon the aquarium and horticulture trades. Thesymposium was a very productive meeting ofthe minds where new ideas were exchangedfor preventing introductions of invasivespecies through these two trades in the future.The IGERT trainees are now in the process offormalizing their results for publication laterthis year.

Theconference featured the addition of our first Wildland Weed FieldCourse, held along Big Chico Creek, where 80 attendees learned aboutintegrated weed management methods from some of the mostexperienced practitioners in the state.

When Symposium attendees weren’t listening to some of the morethan 40 talks, they could peruse research posters or visit our sponsors’exhibits. Joe Silveira of the Sacramento National Wildlife Refugereminded us what we’re working toward with his keynote address on“The Return of Natural Diversity to Great Valley Wildlife Habitat.”On Friday, participants broke into small working and discussiongroups on topics such as Wetlands and Sensitive Habitats, Fire andFuels Treatment, Mapping, and Education/Outreach.

Attendees didn’t spend all of their time listening to talks. During

protect mainstream agriculture on the U.S.mainland from Hawaii’s pests but noreciprocal measures for protecting Hawaii(OTA 1993). Clearly, the quarantine system isnot protecting Hawaii from what Bright(1999) termed the “pathogens of globaliza-tion.”

Hawaii has been one of the mostunfortunate locations in the world as far aspest introduction is concerned, and itsbiodiversity and agriculture have suffered.The state is in the midst of an invasive speciescrisis affecting not only the archipelago'shighly endemic biota, but also overallenvironmental and human health, andviability of its tourism- and agriculture-basedeconomy (CGAPS 1996). The InvasiveSpecies Specialist Group of the WorldConservation Union (i.e., IUCN) recentlydeveloped a list of “100 of the World's WorstInvasive Species” (ISSG 2002); Hawaii has 47of them.

Hawaii has roughly the same totalnumber of nonnative arthropod species as thecontinental United States. McGregor(1973) speculated on the reason:“Although there is much greaterdiversity of crops and habitats withinthe continental United States , theseare dispersed over a vastly larger landarea. In Hawaii , where the overalldiversity is less, the various habitatsare more readily accessible from theprincipal port of entry.” The moremoderate and stable climate of Hawaiiis also more favorable to an invadingspecies than the climate in much ofthe United States. Furthermore,McGregor (1973) recognized thispoint in relation to agriculturalquarantine: “(for insects and mites) inthe period 1942-72 the rate ofcolonization per thousand squaremiles was 40 species, 500 times therate of [the] continental UnitedStates.” There is no evidence toindicate that this pattern has changedin the following 30 years.

More native species have beeneliminated in Hawaii than anywhereelse in the United States . Hawaii haslost about 8% of its native plantspecies and an additional 29% are atrisk (Loope 1998). The state has lost27 of its 73 historically known birdspecies and about 900 of 1,263described land snail species (Loope

National Parks, continued from pg. 5 1998). With just 0.2% of the U.S. land area,Hawaii has about 30% of U.S. endangeredspecies. Although habitat destruction hasbeen an important cause of extinction andendangerment, the introduction and spreadof invasive alien species has contributed in amajor way in the past and is now thepredominant cause of biodiversity loss inHawaii.

Still, much biological richness is left inHawaii’s national parks, mostly at highelevations, but what is left is threatened byold, new, and future invasions. The invasivetree Miconia calvescens is an alarming andimminent threat. This large-leaved, shade-tolerant tree from tropical America has greatlyreduced biodiversity over most of the rainforest area of Tahiti (Meyer 1996, Meyer andFlorence 1996) and promises to do the samein Hawaii without major managementintervention. Hawaii’s national parks andHawaii’s NPS Exotic Plant Management Teamare very much involved in interagency effortsto manage M. calvescens (e.g. Loope and Reeser2001).

Good models for improved preventionfor Hawaii exist in the largely successfulpreventive systems in place in New Zealandand Australia. In these countries the publicaccepts laws and procedures, some involving asmall loss of personal freedom, as the pricethat must be paid for protecting agriculture,forests, and native ecosystems. New Zealandhas comprehensive biosecurity legislation anda highly rigorous border control system,utilizing trained dogs and X-ray technology(Baskin 2002, Loope 2004). Australia has arelatively successful plant screening systemthat has evaluated thousands of new plantintroductions since its inception (Pheloung etal. 1999, Baskin 2002).

The stakes are high in Hawaii because ofthe state’s world-class biota. No location in theworld rivals Hawaii as a showcase for bioticevolution in isolation and adaptive radia-tion—not even the famed Galapagosarchipelago (Williamson 1981). In Hawaii,the National Park Service emerged as a leaderin conservation biology about 1970, turningapathy into action, and showed that extensive

native ecosystems persisted at highelevations in the state. It has pioneeredthe use of fencing as a tool forsustained elimination of feral ungulates(Stone and Loope 1996), serious alienplant control within designated“special ecological areas” (Tunison andStone 1992), pushing for betterquarantine measures at airports andharbors (Reeser 2001), and drawingthe line against Miconia and otherinvasive species. The National ParkService in Hawaii is well aware that itcannot rest on its laurels, however(Bryan Harry, NPS Pacific area director,personal communication, 2004).

Lag time often masks biologicalinvasions on the U.S. mainland

Given unabated action of similarforces responsible for continuedecological degradation—habitatdestruction and fragmentation,biological invasion, and cascadingeffects—biodiversity of mainlandnational parks is clearly at risk(Vitousek et al. 1997). Meanwhile,Hawaii comprises a useful testingground where strategies to prevent andcombat invasions can be applied,tested, and refined.

Lag time is an important andunderappreciated phenomenon ininvasion biology and tends to mask the

Miconia tunnel. Biologist Jean-Yves Meyer stands beneath atypical forest of the invasive tree Miconia calvescens in Tahiti.Miconia has become recognized as an invader capable ofextinguishing biodiversity in island rainforests, and is beingaggressively combated by the Hawaii Exotic Plant Manage-ment Team and others in Hawaii .

pervasiveness of invasive species on the NorthAmerican continent. For example, very manynonnative insect and disease problems ineastern North America went unnoticedinitially but have gathered momentum andbecome acutely problematic with time. Forexample, white pine blister rust (Cronartiumribicola), introduced with nursery stock fromEurope, has been in this country for morethan a century (Maloy 2001), but it is justnow killing most of the whitebark pine (Pinusalbicaulis) trees in the northern RockyMountains from Glacier National Park toYellowstone and Grand Teton.

Likewise, hemlock woolly adelgid (Adelgestsugae), a tiny insect, also illustrates well thecase of serious invasions, which are revealed asserious only gradually. Native to Asia, itreached the western United States in the1920s and the eastern part of the country inthe 1950s, but the conventional wisdom wasthat it attacked only cultivated hemlocks (VanDriesche and Van Driesche 2000). In the1980s, reports surfaced of eastern hemlockdeath in Virginia, and the infestation has nowbecome a huge problem from New Englandto North Carolina and is slowly spreadingwestward. This may be an invasion that couldcause functional extinction of two hemlockspecies, eastern hemlock (Tsuga canadensis)and Carolina hemlock (Tsuga caroliniana).

Lag times are not always as long. Balsamwoolly adelgid (Adelges piceae) has virtuallyeliminated Fraser fir (Abies fraseri) in GreatSmoky Mountains National Park; it was firstnoted in the United States about 1950 andstarted attacking fir in the Smokies in the1970s. Dogwood anthracnose (Disculadestructive), first detected in the country in the1970s, was reducing or eliminating floweringdogwood (Cornus florida) in many easternnational park areas by the 1990s (Langdonand Johnston 1992).

Fast-moving and newly emergentinvasive diseases deservedly get the mostattention. Sudden oak death syndrome(caused by the fungus Phytophthora ramorum)is a high-visibility problem that popped up in1995 in California and kills healthy treeswithin four months (Kliejunas 2001). Fornearly a decade, the fungus in the UnitedStates had been confined to Pacific states, butits chances of invading southeastern states,where numerous potentially susceptible oak(Quercus) species are ecological dominants, waslearned to have been hastened in early 2004.At that time it was found that in spite of thebest preventative efforts of APHIS, one large,infected nursery in Los Angeles had shipped

susceptible plant material widely. An APHISupdate reported, “As of June 15, P. ramorumhas been confirmed in plants traced forwardfrom the initially positive Los Angles Countywholesaler at 118 sites in 16 states,” including11 states in the southeast (APHIS 2004).

How many more sleeper invasions havealready been inoculated within ecosystemsworldwide by the recent burgeoning oftrade—involving diverse pathways from solid-wood packing and raw lumber to seed tradeon the Internet? And how much are protec-tive systems going to improve in the comingdecades in addressing continuing inocula-tions? In my view, change is going to dependmore than anything on awareness.

Who will tell the people?Entomologists Nemiela and Mattson, in

a 1996 article in BioScience, stated (p. 751):“When the outrageous economic andecological costs of the wanton spread ofexisting exotics and continued entry of newones become common knowledge, it isinevitable that there will be a public outcryfor actions to mitigate the potentially direconsequences.” Whose responsibility is it toinform the public? One might conclude thatthe seriousness of the problem of biologicalinvasions seems to be largely unrecognized inthe consciousness of the American public.Among environmental concerns, clean air and

clean water perhaps understandably seem toattract the most attention (since their directeffects are readily imagined). The reality is thatbiological invasions threaten much more thanthe integrity of natural ecosystems of nationalparks. They pose immense threats to the U.S.economy, agriculture, and forest resources,and to the public health and quality of life ofU.S. citizens. Yet it seems that almost nowherein American society is this message beingconveyed effectively. Admittedly, the pressreports with high frequency on specificinvading species, but only rarely produces in-depth analyses relevant to the general problemof invasions (e.g. Nash 2004, Choo 2004).

How can NPS rise to the challenge?The issue of the threat of invasive alien

species to natural areas obviously presentshuge challenges, but there are many possibili-ties for working toward “solutions.” A recentissue of BioScience presents an upbeat mix ofideas on promising approaches by knowledge-able scientists (Dybas 2004). One suchscientist's (Daniel Simberloff ) presentationwas entitled “We can win this war: Thedangers of pessimism about introducedspecies.” Another (David Lodge) is quoted ashaving made the observation that screeningspecies for invasiveness is one of the essentials

and that “we have or are developing the toolsto do that. The management and policy tools,however, lag way behind.” A third scientist(Ann Bartuska) expressed frustration over“how little we have done about dealing with… [the invasive species issue]—given how bigit is, how clearly we know the impacts, howwidespread it is, and how it touches everyonein one way or another.… We seem to have thepolitical will and the public will to really takeon fire [in wildland management] in a bigway… but we don't seem to be able to do thesame with invasive species.” Her suggestedsolutions included “integrated vectormanagement” and “an effective early detectionrapid response system.”

The National Park Service has specialincentives for ramping up its efforts to addressthe invasive species issue. National parks andtheir ecosystems provide an excellent opportu-nity to bring the invasions message to the U.S.

public. Parks have been identified in the past(originally by NPS Director George Hartzogin the early 1970s) as “miners’ canaries” forU.S. environmental health and indeed canwell serve as such for communication of theinvasions message. Some regions and parks aremuch more susceptible to invasions thanothers, with some already showing substantialdegradation. Parks in Hawaii , California, andFlorida are especially affected by invasions.

Those parks provide unfortunate but stronglessons to be learned by NPS employees andthe general public. Those fortunate regionsand parks that have up to now been lesssusceptible and have largely escaped damageby invasions can learn from their neighborsand anticipate threats posed by futureinvasions.

The 1916 NPS Organic Act states clearlythat the national parks are to be kept “unim-paired for the enjoyment of future genera-tions.” The National Park Service now appearsto be faced most ominously with massiveimpairment of the parks’ natural resources bybiological invasions from outside. One role forthe National Park Service might be toaccelerate its proactive role in informing itsemployees and the American public of theinsidious nature of biological invasions.Another might be to include serious analysesof the importance of proactive quarantinesystems suitable for regions at risk such as theHawaiian Islands (see Reeser 2002). Major

breakthroughs in science, policy, andmanagement will likely be needed to addressthe complex and important issue of biologicalinvasions if substantial impairment of theparks is to be averted.
