A research program is a setofinterdependentpostulatesonwhichonlya portion of the scientic community agrees(Lakatos1980, Stengers2000[1993]). It isthereforeunlikea paradigm, whichintheKuhniansense of normal science assumesconicting models purporting to explain thatthesamephenomenacannotcoexist(Kuhn1970, Stengers 2000 [1993]). In anthropology,researchprograms includecultural ecologyand sociobiology; a generation ago, researchprograms in the social sciences would have in-cluded psychoanalysis and Marxism (Lakatos1999 [1973]). In ecology, systems theory andnonequilibrium dynamics constitute separateresearch programs (Zimmerer 2000).Research programs consist of three to vehard-corepostulates(Lakatos1999[1973]).Inhistorical ecology, thepostulatesarethefollowing: (a) Practically all environments onEarth have been affected by humans, includ-ing in a broad sense behavioral activities of thegenus Homo (Kidder & Bal ee 1998, Redman1999, Sauer 1956), althoughothers wouldlimitthewide-rangingeffectofhumansonthe environment to only the entire time dat-ing fromthe beginning of the Holocene,thatis,thetimecoincidingwiththebegin-nings of agriculture (Dickinson 2000); (b) hu-man nature is not programmed genetically orotherwisetolessenoraugment speciesdi-versityandotherenvironmentalparameters(Crumley2001, Hayashida2005); (c)itfol-lows that kinds of societies dened by vari-ous socioeconomic, political, and cultural cri-teria impact landscapes in dissimilar ways, assome landscapes are less disturbed (and richerin species) than others; and (d) human inter-actions with landscapes in a broad variety ofhistorical andecological contexts may be stud-ied as a total (integrative) phenomenon (Bal ee1998b, Egan&Howell 2001b, Rival 2006,Sutton & Anderson 2004).Historical ecologiststakealongviewofhistory and landscapes and thus tend to be atvariance with earlier established research pro-grams of environmental anthropology (Bal ee&Erickson2006b; Braudel 1980; Crumley1994, 1998, 2003; Kidder &Bal ee 1998;Russell 1997). Historical ecology exempliesrevisionismof earlier regnant concepts in cul-tural ecology, cultural evolutionism, culturalmaterialism, andecological systems theory(Dove 2001; cf. Headland1997, Rival 2006). Itis an interdisciplinary means of grappling withapplications from both the social sciences andlifesciences(Bal ee1998a,b; Crumley1994,1998, 2003), the most important of which forstrategic environmental concerns is restora-tionecology, asynonymofappliedhistori-cal ecology (Anderson 2001, Egan & Howell2001a,b, Higgs 2003).Historical ecology arose out of empiricalstudies that showed problems in the applica-tionofecological anthropologytocomplexsocieties. Peasantries and other complex soci-eties exhibiting different socioeconomic stratacould not be analyzed according to method-ologies developed in cultural ecology becausecultural ecology referred only to classless orsimple societies, wherein it was thought a lin-ear relationship existed between key featuresof indigenoustechnologyandtheenviron-mentontheonehandandlowpopulationsize and simple political organization of so-cietyontheother (Boglioli 2000, Cole&Wolf 1974). Such societies were not seen toexert so much a long-term effect on the lo-cal environment as to be adapted to its pu-tative constraints (Adams 1998; Bal ee 1989;Bal ee & Erickson 2006b; Cole & Wolf 1974;Stahl 1996; Wolf 1982, 1999). Systems the-ory in ecological anthropology was an attemptto bring more mathematical rigor to the sub-ject matter, especially by conceiving of humansocieties as populations having exchanges of76 Bal eeAnnu.

Sys-temstheoryinanthropology, asinecology,wasahistoricalandexcludedhumanagencyand intentionality inthe landscape (Dove2001, Wolf 1999; cf. Biersaack 1999).A SECOND WORLDIn historical ecology the landscape is a placeof interaction with a temporal dimension thatis as historical andcultural as it is evolu-tionaryperse, ifnotmoreso, uponwhichpasteventshavebeeninscribed, sometimessubtly, ontheland(Crumley2003, Ingold1993, Marquardt &Crumley1987, Neves&Petersen2006, Russell 1997). Historicalecologyregisterssimpleforagersandswid-den horticulturalists as agents of history man-ifesting cultural pasts that defy placement ina stage of political evolution (Cormier 2003,Crumley 2003, Politis 2001, Rival 2002, Rival2006, Zent &Zent 2004). Wolf (1982) showedthat cultural ecology lacked a unied theoryand could not rise above explanations of sin-gle cases because of its emphasis on humanadaptations to the environment, rather thandeeming society engaged with that environ-ment and acting, effectively, to change it overtime. Wolf (1999) argued that environmentalanthropology needed to abandon systems the-ory and become both political and historicalecology to assess changes in relations betweenhuman societies and their landscapes.Historical ecology has challenged the no-tion of pristine primitives (Wolf 1982) andvirgin rainforests (Bal ee 1989, Denevan 1992)through different but ultimately convergentstrands of interdisciplinarythinkinginan-thropology,geography,history,andecology(Hayashida 2005). The notion that landscapeshave history, and that natural things in givenenvironmentsarehistoriographicindicesofthose environments, has several precursors indiverseelds, especiallyinhistoryandge-ography. HistorianCronons (1983) classicstudyof theimpact of precolonial IndiansinNewEnglandinshapingthelandscapethought by the Puritans to be pristine was acareful empirical challenge to the concept ofpristine primitives harnessed to the restraintsof virginforests (Turner 2005). Theprin-cipal mechanismthat createdtheparklandlandscapesnotedbythePuritanswascon-trolled (or broadcast) re (Cronon 1983, Pyne1998).Indigenous societies molded not onlymosaic-like environments with patches rich inutilitarian natural resources, but also in somecases enhanced local (alpha) species diversity.Specically, controlled(broadcast) res arenow considered to have enhanced local land-scape heterogeneity as well as species diversity(especially of rare species), partly by prevent-ing fuel buildups and the ensuing possibility ofdestructive wildres in numerous indigenousareas of North America, South America, andAustralia(Anderson1999; Birdetal. 2005;Boyd1999a,b;Lunt&Spooner2005;Mis-try et al. 2005; Posey 1985; Pyne 1991, 1998;Robbins 1999; Storm 2002; Winthrop 2001;cf. Fosteretal. 2004). Thatrebyhumanagents in controlled cases amplies diversity,whereas wildres and combustion by fossil fu-els tend to have degrading effects, refers onebacktothenotionoflandscape, wherehu-mans and the environment meet in an analyticwhole, with a temporal dimension that denesthe relationship (Bal ee 1998a; Crumley 1994,2003; Ingold1993; Marquardt &Crumley1987; Pyne 1998).Thisnotionoflandscapeinitsmostre-cent versionoriginatesincultural andhis-torical geography (Denevan 2001, Doolittle2000, Katesetal. 1990, Olwig2003, Rival2006, Sutton&Anderson2004). Geogra-phers earlyderivedtheideaof aninsepa-rabilityof humansandtheenvironment inthe context of a landscape (Landschaft) partlyfromGermanlandscapegardeners andar-chitects of the nineteenth century (Crumley1994, Hall 2005, Wolschke-Bulmahn2004)and from schools of nineteenth-century land-scape painters in Europe, North America, andAustraliawhosoughttocapturetheirideasof wilderness andits embeddedhumanity,www.annualreviews.org Historical Ecology 77Annu.

Cicerowroteofhow through domestication, fertilization, andirrigation humans inuenced the creation of asecond world apart from the so-called naturalone (Glacken 1967, Hughes 1975, Wolschke-Bulmahn 2004), a concept echoed 1700 yearslater in the Enlightenment (Roger 1997).Ciceros secondworldwas abuilt envi-ronment. He might not have recognized sec-ond worlds in sub-Saharan Africa, Australia,lowland South America, and much of NorthAmerica, just as Renaissance and Enlighten-ment thinking did not, considering such re-gions to be wilderness (Rafes 2002, Roger1997). The second world, from a nineteenth-centuryEuropeanperspective, incorporatednatural and cultural things together, often ina garden-likesetting, as seenespeciallyinItalyandGermany(Hall 2005, Wolschke-Bulmahn 2004). The garden as a spatially de-ned landscape involving nature and cultureantedates European civilization, having beenborrowedbyHellenisticsocietyfromEastAsia (Glacken 1967).The garden is the underlying premise ofa landscape, for there humans habitually in-teract with other living forms, both in acyclical fashion, andinthelong-term(in-volving at least decades) and very long-term(involving centuries), a concept known aslongue dur ee (Braudel 1980). Historical ecol-ogists havediscernedgardens inthemidstof seeming wilderness in both the Neotrop-ics andPaleotropics andhave referredtothese as forest gardens, forest elds, trail gar-dens, war gardens, man-made tropical forests,cultural or anthropogenic forests, anddo-mesticated landscapes (Bal ee 1989; Clement1999a; Denevan 1992, 2001, 2006; Erickson2006; G omez-Pompa et al. 1987, 1990;Heckenberger et al. 2003; Janzen 1998; Posey1985; Posey &Bal ee 1989; Rival 2006). Thesearedistinguishedfromcultural landscapes,which are not so much disturbed by humansasindexical(byiconicbiotaandplacesdis-cernibletothenakedeye)oflocalsocietiesandtheirlong-termhistoryinsitu(Stofeet al. 2003). Historical ecologists also examineindexical functions of biota in specic land-scapes affected by human activity over time(Feely-Harnik2001, Verheyenet al. 2004,Walker 2000).There is a long-standing division amongEuropean geographers and foresters betweendomesticated (or culturalized) and naturallandscapes(Alexander&Butler2004). Theconcept of pristine forests is gradually beingreplacedwithamorehedgednotionofoldgrowth forest. The notion of old growth for-est in Europe as well as North America in-cludes forests that may have been disturbedby humans although not for long periods oftime, so-called rst nature (Rudel 2002). In-creasing evidence, however, suggests interme-diate disturbance may have lasting legacies, ofthe longue dur ee sort, in terms of redeningvegetationpatterns(Turner2005).Europesculturalizedlandscapesrunthegamutfromtreeless zones to mature forests similar to for-mer woodland, yet none is primary, althoughrelic species, such as lichens, bryophytes, andmycorrhizal fungi, aswell asafewancienttrees, maystill befound(Myers &Bazely2003).

Inmorerecent times, anumber ofscholars have argued that agricultural impactsdatingfromtheHolocenehaveessentiallytransformedtheworldsomuchthathardlyany part of it is pristine per se and that, in-deed, humans created the landscapes typicallyreferred to as examples of Holocene environ-ments (Denevan 1992, Dickinson 2000). Thenotion that certain species-rich forested land-scapes of Greater Amazonia, Middle America,andWest Africawerepristinewildernesseswas challenged by new data and interpreta-tions in the past two decades of the twentiethcenturyfromanthropologists, geographers,and biologists (Bal ee 1989; Bal ee &Campbell1990; Denevan 1992, 2001; Fairhead &Leach1996; G omez-Pompa &Kraus 1992; G omez-Pompa et al. 1987; Hayashida 2005; Leach &Fairhead2000; Posey1985; Posey&Bal ee1989; Rival 2006; Stahl 1996; cf. Parker 1992),who supplied evidence of human activity inthe origin of these landscapes.In historical ecology, the concept of land-scapetransformation, resultinginso-calledman-made forests (Campbell et al. 2006,G omez-Pompa et al. 1987, Wiseman 1978),was derived initially from evidence of agricul-ture and agroforestry; more recent work sug-gests foraging and trekking societies have alsoinuenced forest composition through activ-ities such as sowing propagules of trees thatattract honeybees without using re for for-est clearance (Zent & Zent 2004) and aban-doningcampyetleavingchangesinspeciescompositionthatinvolvethecoexistenceofcrops and noncrops (Politis 2001, Rival 2002,Rival 2006). The evidence of classless societiesas disturbance agents that modied and man-agedenvironments earlierregardedas sys-temic concatenations of interactive, primevalbiota and physical elements represents, in his-torical ecology, a divergence away from thecore postulates of cultural ecology as well asequilibrium theory.OTHER ECOLOGIES, OTHERHISTORIESThedistinctionbetweenhistorical ecologyandother ecological viewpoints anddisci-plines has to do with anthropocentrismin oneguise or another (Bal ee & Erickson 2006b).Historical ecology differs from cultural ecol-ogyprincipallyonthecriterionof humanagency, as well as adaptationtothe envi-ronment. Cultural ecology holds that theenvironment is not transformable. Rather,humans must adapt their cultures, technolo-gies, and populations to it. Typically culturalecologycannot explainhigher-order socialphenomenasuchascities, states, andtheirdependent hinterlands because the core pos-tulates are based on the environmentaldeterminismof societies withsimpletech-nologies (cf. Cole & Wolf 1974). Historicalmaterialismasaresearchprogram(Lakatos1999 [1973]) allows for human agency in ini-tial appropriations from and transformationsof nature (Wolf 1982) but does not conceiveof theenvironment, oncechangedbyhu-man hands, exerting a longer-term effect onsubsequent human cultures in the region ofthe changes (Bal ee 1998a,b). Historical ma-terialismlackedthelongue dur ee notionofthe Annales historical school, which would bedeveloped a century later (Crumley 1998).Historical ecology differs fromanthro-pological systems ecologyitself acritiqueof cultural ecologybymovingawayfroma concern with the functionalist adaptationsof humanbehaviortogivenenvironmentalconditions andsteadystates of theecosys-tem(Wolf 1999; cf. Biersaack 1999). Althoughhistorical ecology underscores the impor-tanceof timeandcontingencyinenviron-mental change (Botkin 1990, Scoones 1999,Zimmerer2000), asdoesthenewecology,it is not aformulatedrecordof geologicalchanges that took place in the absence of hu-mans, astudyof humanresponsetonatu-ral catastrophes (cf. Bilsky 1980), or merelyrecordedhistoryorprehistoryofanyenvi-ronment(s). It differs from the new ecology,www.annualreviews.org Historical Ecology 79Annu. Rev. Anthropol. 2006.35:75-98.

Historical ecology involves a tripar-tite array of conceptions of human time, bor-rowedfromtheAnnales, especiallythefol-lowing: (a) ev enement (event) as a short-term,episodic phenomenon; (b) conjoncture (cycle),involving repetitive statistical patterns over adecade, quarter-century, or half-century or so;and (c) longue dur ee, empirical patterns of his-tory and prehistory occurring over centuries(Braudel 1980, Crumley 2003).Historical ecology has been most of-ten conated with environmental history.Environmental history is a fairly well-established interdisciplinary subject (Beinart&McGregor 2003, Crosby2004, Hughes2001, Worster 1993), but it is not a perspec-tive that articulates hard-core postulates, suchas historical ecology does. In this sense, his-torical ecology is not a part of environmentalhistory nor is it parallel to it as a separate wayof thinking (cf. Moran 2000, Myllntaus 2001).Environmental history encompasses the fol-lowing: the comparative historyof humanactivityinwidelyseparatedbutstructurallysimilar environments having similar politico-economic and historical conditions seen as re-sulting in convergent behaviors, the history ofgreenmovementsandtherelationofthesetogovernment policy, thehistoryof envi-ronmental sciences and forestry, and the his-toriographyof environmental historywrit-ing(Beinart &Coates1995, Crosby2004,Hughes 2001, Worster 1994). Historical ecol-ogy of a landscape, such as the Llanos de Mo-jos of Bolivia or the Upper Xingu of Brazil(Erickson & Bal ee 2006, Heckenberger et al.2003, Mann 2002), would not be coterminouswith environmental history of the same be-cause historical ecology subscribes to a singletheory of history and offers a model of howandwhythelandscapeunderwenttransfor-mation, regardless of the unique chronologyof events.Historical ecology differs from landscapeecology(cf. Moran2000). Landscapeecol-ogy focuses on spatial heterogeneity reectedinclustersof ecosystemsand, withnotableexceptions (Hayashida2005, Turner2005),tendstoexclude, asaprinciple, intermedi-ate human disturbance of environments andtemporal changes in them as a qualitative fac-tor in landscape transformation (e.g., Forman& Godron 1986, Turner 2005; see critiquesby Crumley 1998, 2003; Denevan 2006). Theconcepts of design, ecology, and architectureof landscapes in the modern senses seem toenvisionre-educationof humanbeings sotheycanlivemoreharmoniouslywithself-contained natural systems and processes. Ba-sically landscape ecology does not involvehumans recapturing indigenous or localknowledge that could be of use to restorationecology (Gunn 1994), which, in at least oneof its crucial theoretical aspects, authenticity,is close to or the same as historical ecology(Anderson2001, Egan&Howell 2001a,b,Higgs 2003, Jones 2004).Historical ecology is sometimes comparedwith, orthought tobethesameas, polit-ical ecology(e.g., Wolf 1999). Manyhavedeemedthe termpolitical ecology a misnomerby statingthat it concerns only politics andnotecology (Vayda & Walters 1999) and that itdoesnt increase knowledge relevant to ecol-ogy and the life sciences (Scoones 1999). Insomeways political ecologyis moresimi-lar to environmental history with its empha-sisonthecritiqueofconservationistmove-ments(Dove2001). Political ecologydoes,however, comprise one feature relevant tohistorical ecology, towit: thepossibilityofunderstandingandapplyingthecritiqueofregnant folkmodelsof natureandtheen-vironmentforbuildingamoreenlightenedapproach to the reconstruction of past land-scapes. Political ecologycouldbe synony-mous with applied historical ecology, but theterm itself is perhaps still used too widely indisparatesensestorefertoasingleeldortheory.The anthropological ecology of prac-tice(inuencedbythesociologyof PierreBourdieu) instantiates the third hard-core80 Bal eeAnnu.

The proposal of an evenemen-tal (sic)oreventecology(Vayda&Walters1999) is bound to the particularistic lim-itations of case-by-case studies, similar tocultural ecology (Wolf 1982), and the omis-sionof humanagencyinlandscapeforma-tion; thereforeitdoesnotrepresentanewconcept. The notion of ev enement in the An-nales isbut theshort-termepisodicfeatureaffecting the formation of new landscapestheothers areconjonctures andlongue dur ee(Braudel 1980, Crumley 1998), concepts in-corporatedintothecorepostulates of his-torical ecology. These postulates are, more-over, at variance with equilibrium theory andsystems theoryessentially synonymsinecology.Historical ecologyis unlike, andfunda-mentally at odds with, ecological systems the-ory by a similar logicthe logic of the behav-iorofsentient, sapientbeingswithculturalcapacitiesnotjusttotransformspecies-richenvironments intobarrens of lowdiversityand landscape homogeneity, which clearly hu-mans can do and have done, but also in certaincases to heighten the species diversity of lo-cal environments through ongoing resource-management practices. Historical ecologyanswers the call for an anthropocentric as op-posedtoanecocentricor geocentricecol-ogy (Bal ee & Erickson 2006a,b, Erickson &Bal ee2006). Somethinkinginecologyin-terprets these practices as always destructive,but that view is derived from the misunder-standingofhumanagencyasaprincipleofsome disturbance of the environment, whichat agivenlevel of intensitymaybeessen-tial tosustainingdiversity itself, a ndingcomprehensible within a historical-ecologicalviewpoint, which has afnities, as such, withothermodelsincontemporaryecology, in-cluding nonequilibriumdynamics (Botkin1990, Huston 1994, Turner 2005, Zimmerer2000).HISTORICAL CONTINGENCYAND ECOLOGICALSUCCESSIONEnvironmentsecosystems in systemstheoryundergo histories of changes in theirfundamentalcharacteristicssimilartosuitesor guilds of species of plants andanimalsover time.

With regard to forestcommunities, these would be trees and otherstructural organisms (Huston 1994). Incontrast, small (suchasinsular) ecosystemsconsist for themost part of r-selectedor-ganisms, that is, plants with short life spans,highnumbersofoffspring, andfastgrowthrates. These ecosystems are more easilyinvaded by species from continents. Becauseislandsdevelopthroughgeneticdriftclinesand endemism(as withDarwins nches),they are also more prone to extinctions. Thetheory, called island biogeography theory(MacArthur&Wilson1967),proposesthatthe further an island is from a continent, thehigher its endemismand species diversityandthe higher the number of K-selectedorganisms. In contrast, the closer an island isto a continent, all else being equal, the lowerits diversity as a result of its susceptibility toinvasions of organisms fromthe mainlandthat replace local biota in the same or similarnichesandthereforecausetheirextirpationandpossibleextinction(i.e., anoutcomeofcompetitive exclusion).

The theory excludeshistory, and partly for that reason it has beenhard to replicate in the real world of islanddiversity and invasion biology (Huston 1994,Lomolino 2000, Simberloff 1997).Species invasionis one kind of disturbance.Disturbance traditionally, infact, canbe bioticor abiotic. It can also be cultural and histori-cal. When they are demonstrably natural andunrelated to global warming, to ill-conceivedlevee and dike construction, and to other sortsof human error, hurricanes and oods are abi-otic disturbance agents that can account forthe reductions of forests withmany K-selectedspeciesandtheneargrasslandandsavannaenvironments replete with r-selected species(Huston1994). Hurricanes andoods canalsocause terrestrial environments to become ma-rine ones, for example, by splitting islands intwo (Walker &del Moral 2003). Biotic factorsinclude not only invasive species and their ef-fects on local biodiversity (whether to lessenor replace it with new species), but also or-ganisms that demonstrably alter the landscapeinhabited by other life forms (Schmitz et al.1997, Simberloff 1997).Humans effect and are inuenced bychanges in the landscape. The ancient Greekdichotomy between physis (nature) and nomos(culture) (Glacken 1967, Hughes 2001) thatforeshadows the Cartesian dualismof thebody (material world) versus the mind (think-ing) is inapplicable in understanding ecolog-ical succession as modied or interfered withbyhumansasthedisturbanceagency. His-torical ecologydeals not withthe synthe-sis of humans and the environment, but fo-cuses on the result of their cyclical interaction(conjoncture).Historically the more centralized the po-litical regime (i.e., the more it is similar to astate), the greater the potential for the reduc-tion of species diversity. Advanced industrialtechnologies with fossil fuels have long beenknown to reduce the genetic diversity of cropplants (Kates et al. 1990). Ancient civilizationsusing intensive agriculture (with terracing, ir-rigation, and fertilizers) reduced the diversityof traditional cultivars in agricultural elds asaresult of taxationexigenciesonanarrowrange of foodstuffs (Zimmerer 1993). Inter-estingly, human depopulation, as occurred intheAmazon(andintheAmericasgenerallyand Australia) after contact as a result of theintroduction of new pathogens, can lower theagrodiversity of landraces in areas where localknowledge and behavior are key to the man-agementoftraditionalcrops,includingtreecrops (Clement 1999a,b). If genetic diversitybelow that of the species rank is consideredpart of a regions diversity, then gamma diver-sity has been diminished as a result of peo-ple being removed from the landscape. De-population and other consequences of contacthave led to the loss of agriculture and otherbasic technology altogether, even the disap-pearance of a societys cultural ability tomanu-facture re, a feature once thought a sociocul-tural universal (Bal ee 2000, Cormier 2003).With regard to advanced industrial agri-culture (Kates et al. 1990), fertilization alonetendstoreducebiodiversity(Huston1994)byincreasingthecompetitionfornutrientsamong species originally present on a plot. Itis a paradox of enrichment: Areas of high pri-mary productivity (rich in nutrients) are of-ten impoverished (but not always) in speciesdiversity(Huston1994).Despitehighrain-fall, largetractsoftropical rainforestshavebeen increasingly prone to wildres as a resultof deforestation and possibly global warmingartifacts of the twentieth century to date. Inthe future, the spread of GMOs and their po-tential foruncontrolledgeneowwithna-tivecrops(aresult inpart of efcient dis-persal mechanisms, such as anemochory) mayreduceagro-diversity(Altieri 2004, Burney1995/1996, Pilson & Prendeville 2004).

Primarysuccession refers to the initial colonization ofa substrate that had no life on it before, such asthe succession of organisms on newly formedvolcanic atolls or emergent deltaic islands onthepoint bars of meanderingrivers. Onalonger timescale, the succession of organismsin areas of former glaciation is an example ofprimary succession, as is the replacement ofentire phyla by newones over millions of years(Huston1994). Secondary successionrefers tothe replacement of organisms by other typesof organisms (such as K-selected by r-selectedorganisms) on a substrate that has been dis-turbed, as is the case with well-drained for-est lands when subjected to hurricanes, torna-does, droughts, blowdowns (wind shear), and,as has been especially well studied in the trop-ics, humandisturbance by slash-and-burncul-tivation or some other form of extensive agri-culture. In all cases, both in systems theoryand cultural ecology, the idea is that follow-ing the disturbance, the succession of guildsoforganismsproceedsanew: Inthecaseoftropicalforests, forexample, thesuccessionproceedsfromdominancebyther-selectedspecies tothe climax, the dominance andhigh-est diversity of what are basically K-selectedcommunities.

Themeasurableef-fects of intermediatedisturbancemediatedby humans refer at least to one of the threetypes of species diversity recognized in ecol-ogy, alpha diversity. Alpha diversityis thenumber of species on a restricted locale withconstantenvironmentalparameters(suchasdrainage and soil type). Intermediate distur-bance mediated by humans might also be seenin beta diversity, which is diversity over an en-vironmentalgradientsuchasslopeorrain-fall involving the distance between adjoiningplotspreviouslysingledoutbyalphadiver-sity alone (Campbell et al. 2006, Erickson &Bal ee 2006, Huston 1994). The third type ofdiversity, gamma, is the diversity of an entireregion, such as the Amazon Basin. With re-gard to the Amazon Basin, because most ofthe species diversity predates the Pleistocene(Bush1994, Vieira et al. 2001), prehistoric andearly colonial societies probably had a negli-gible impact, except through the introductionof invasive species (biological invasions), thesespecies occurring in inverse proportionality topre-existing species diversity in the locales ofintroduction. Gamma diversity of Amazonialacks a single, simple explanation (Bush 1994);it requires a complex model, grounded in his-torical ecology, capable of accountingnot onlyfor physical and temporal factors of diverse di-mensions, but also for human-mediated onesimpacting landscapes over time. The conceptof ecological successionthe term originallyusedinsystemsandequilibriumtheoryisstill useful ina dynamic model of environmen-tal change entailing increases and decreases ofbiological diversity (Huston 1994), the prin-cipal focus of inquiry in ecology, but for dif-ferent reasons than in systems ecology. Eco-logical successioninhistorical ecologycanbecalledlandscapetransformation(anthro-pogenic succession), of whichthere are severaltypes.Direct human impacts can be qualitativelyassigned to a scale sensitive to time and place,indicative of least perturbation (e.g., by pre-historic foraging in the Arctic, the puna of theAndes, andthedesert of theGreat Basin),whereaminimal humansignatureremainsonthelandscapefromthat time, tomostperturbed (e.g., by advanced industrial agri-culture and globalization), where prehistoricsignatures are mostly erasedas a result of com-plete replacements of guilds of species and theland-useintensityinuencedbyworldwidedemand on agricultural labor and commodi-ties (Kates et al. 1990, Rudel 2002). The inten-sity of human impacts on landscapes may liein inverse proportionality to species diversitythereon(Burney 1995/1996), regardless of therules that govern access to common resourcesof the landscape (Alvard &Kuznar 2001, Holt84 Bal eeAnnu.

The implicitcorollaryhypothesis is that wherehuman-mediated disturbance was of the least inten-sity, species diversity would have beenhighest.That viewpoint is a premise of wildernessareas. TheseareWesternanalogstosacredgroves (Russell 1997), and their implementa-tion over time has passively affected speciesdistributionandbehavioronthelandscape,forexample,byconvertinghuntedgametoprotectedwildlife(Beinart&Coates1995).Sacred groves have independent histories insub-Saharan Africa, East and South Asia,and Mesoamerica (Byers et al. 2001, G omez-Pompa et al. 1990, Russell 1997), and theirfunction is to protect biotic diversity. Withoutsacredgrovesandwildernessareas,human-mediateddisturbancesmaylessendiversity,especially if landscapes are not heterogeneousin situ (Turner 2005; cf. Renfrew et al. 2005).In other words, to maintain diversity, sacredgroves in diverse cultural contexts suggest afolk belief that human-mediated disturbanceought to be excluded therein. Human distur-bances of the environment, however, are ul-timately scalar and temporal (Allenby 2000,Bal ee 1998b, Crumley 2001, Erickson 2000,Hayashida2005, Peterson&Parker 1998,Sheuyange et al. 2005) and not in their genesissociobiological.Human-mediated disturbances of certaintropicalforestlandscapesinprehistorymayhave decreasedalpha diversity, or hadnomeasurable effect on it. Using the Shannon-Weaver index of biodiversity, Lentz et al.(2002)foundthatanthropogenicforestsre-sulting from ancient Maya agriculture in Be-lize did not result in an increase in biodiver-sity, although forest composition is essentiallyanthropogeniconthestudyplots (seealsoCampbell etal. 2006, G omez-Pompaetal.1987, Wiseman 1978). Conversely, Lentzet al. (2002) do not show a reduction in alphaor beta diversity as a result of human impactsbecause prehistoric baseline inventories of alltaxa are unavailable. Human-mediated distur-bance of lowland Mesoamerica over time ap-pearstohaveresultedinforestsdominatedbyafewspecies[intermsof theirrelativebiomass andother components (e.g., rela-tive density and frequency) of ecological im-portance]. These guilds of dominant speciesare referred to as oligarchies (Campbell et al.2006, Peters et al. 1989).Oligarchic forests (usually replete withfruittreesandothereconomicplants)con-trast withsacredgrovesorotherrelativelyundisturbed forests existing in areas used bytraditional societies totheextent that tra-ditional patterns of human-mediated distur-bance specically involving broadcast andswidden burning result in a mosaic of land-scapes. Recent work suggests such mosaicslandscape heterogeneitytend to increasenot only density of wildlife, but also beta di-versity of ora and fauna. Intermediate dis-turbancebytraditional societiesemployingbroadcast reinAustralia, Africa, andtheNeotropics has demonstrably resulted in in-creases of alpha diversity of vegetation (Birdet al. 2005, Lunt &Spooner2005, Mistryet al. 2005, Pyne 1998, Sheuyange et al. 2005).Inotherwords, intheseinstances, human-mediated intermediate disturbance and man-agement of tropical forest biotas may be es-sential totheexplanationof theirdiversityin situ.

Old fallow forests in-stantiate anthropogenic secondary succession.Forest inventories (completed using standardbiological inventory procedures as discussedin Campbell et al. 2006) of 4 ha of old fallowand 4 ha each of nearby high forest across Pre-Amazonia showed that (a) tree alpha diversitymeasures between fallow forest and high for-est were insignicantly different; (b) adjacentplots of high forest and fallow forest sharedonlyapproximatelyone-halfthenumberofsharedspecieswithininventoryplotsofei-ther type regardless of distance between thosemore similar plots in the same category; and(c) the effect is a net gain in both alpha andbeta diversity, the latter involving the gradi-ent of time (Huston 1994), the high forest be-ing older than the fallow forests (Bal ee 1993,Bal ee 1998b).Secondary forests are not necessarily moreimpoverished in diversity than primary forests(Schulzeetal. 2004). Evenifsoilsinmanysecondary forests are signicantly more fer-tilethanthoseofprimaryforests(Denevan2001, 2006; Erickson 2003; Erickson & Bal ee2006; Neves & Petersen 2006), the secondaryforest soils have not noticeably been reportedto suffer fromthe paradox of enrichment. Thehabitat of the Sirion o Indians of the BolivianAmazon encompasses a heterogeneous land-scape of well-drained forests on relic mounds,slightly inundated forests at the base of suchmounds (called pampa forest), and seasonallyinundated and poorly drained savannas, whichaccount for approximately two-thirds of thelandscape (Erickson 2003, 2006; Erickson &Bal ee 2006; Townsend 1996). Mound forestsare all anthropogenic and date from approx-imately 500 to 1000 years since the time oftheir construction and continuous habitation;pampaforestsarealsoanthropogenic, arti-facts of mound construction. Two 1-ha treeinventories, one of a mound forest 18 m inheight and the other of a nearby pampa for-est, showed (a) a similarity in the number ofspecies, with 55 on the mound forest and 53in the pampa forest; (b) a shared 24 speciesbetween the two forests (yielding a large per-centage compared with Pre-Amazonia); (c) atotal number of species in both forests of 84[(55 +53) (24) = 84]; (d) anda dominance ofoligarchies in both forest types (the 10 ecolog-ically most important species on the moundinventory constitute 65.4% of all importancevalues of all trees on the plot, and the top 10on the pampa inventory represent 70.9% ofall importance values of all trees on that plot).The oligarchies are, however, somewhat dif-ferent (with one species of palmhaving an im-portancevalueof46.21onthemoundand9.21 on the pampa and another palm specieshavinganimportancevalueof 41.2onthemoundand83.27onthepampa), whichisprobably a result of slope (Erickson & Bal ee2006). Savannas are the original, oldest land-scape, and these are maintained by periodicburning (Erickson 2006). Flooding occurs inthe savanna every year, and it alternates with amarked dry season. The total number of vas-cular plant species in the savanna is less than20 (Townsend 1996), with sedges and grassesby far most dominant.The primary landscape transformationthat accruedat the Ibibate MoundCom-plex(themoundandadjoiningpampafor-est) wouldbe, inecological terms, a pri-mary succession, althoughthat termmostcommonlyexcludesanthropogenesisof the86 Bal eeAnnu.

The transfor-mationinvolvedasweepingreplacementofsavannaspecies withood-intolerant trees,havinganalphadiversityof several ordersof magnitude higher than the savanna. Com-parable mounds, specically prehistoric shellmiddens (including gastropods and bivalves ofmany different species) in southwest FloridaandsoutheasternLouisiana, whichsupporthigher diversity than any nearby marshes re-gardless of salinity levels, represent human-mediated increases in alpha diversity (Kidder1998, Marquardt 1992). Therefore forestecology in these cases of primary successionwithout natural causes is actually an artifactof culture and society. Perhaps to representbetter and distinguish the impact of human-mediated disturbance of the environment,given that it is scalar and temporal (Peterson& Parker 1998, Sheuyange et al. 2005), oneshouldthereforerefertoprimaryandsec-ondarylandscapetransformationwhendis-cussing biotic and environmental change on ahumanscale of time. Inother words, alpha andbeta diversity are amenable to analysis in allthree modes of historical time (Braudel 1980)and are hence the denitive material of his-torical ecology.INVASIVE SPECIES ANDLANDSCAPE HISTORIESBiological invasions sometimes refer only toinvasivespeciesthat replaceother(usually)structurallysimilar species inthenewen-vironment, but the termhere refers bothto invasive species in the conventional senseand invasive diseases (Turner 2005), includ-ing bacterial, protozoan, viral, and prion in-fections, that take on epidemic characteristicsin regard to previously unexposed native oraand fauna, including humans (Table 1). Theintegrationof landscape ecology and epidemi-ology (Turner 2005) is analogous to the recog-nition in historical ecology that human activ-ity has been associated with a variety of newpathogens and their distribution and that hu-man societies political organization mirrorstheir susceptibility to epidemic disease, as wellas their potential to generate biological inva-sions in new environments (Newson 1998).Biological invasions that involve the trans-ferandspreadofinvasivespeciesfromonepointtoanotherhavebeentermedsucces-sion in action (Myers & Bazely 2003). Inva-sive species are introduced (exotic) species ofplants and animals that have become weedysupplanters of existing(native) ora andfauna.Denitions vary, but usually weedy organismsare considered out of place; they multiply andspread rapidly at the expense of other organ-isms(Crosby2004, Myers&Bazely2003).Only a minority of introduced species becameinvasive. Thesuccessofinvasivespecies, asweeds, depends on biotic and historical fac-tors, alone or in combination, specic in eachcase. The invasive species may have no nat-ural enemies in the place of introduction (aswith the Brazilian rubber trees in Malaysia), aview originally proposed by Darwin (Hierroet al. 2005), or they may ll an empty niche inthe place of introduction (Hierro et al. 2005).They may have higher numbers of duplicatechromosomes (suchas tetraploids), whichgivethemgreaterreproductivesuccess,asisthecase of all invasive grass species from EuropeinNorthAmerica(Myers&Bazely2003).Structurally, invasive species are likely to beruderal (Hierroet al. 2005, Huston1994)rather than treelike, but there are many ex-ceptions. They may exude secondary metabo-lites toxic to native biota but not to others intheir place of origin (Hierro et al. 2005). Inva-sive species may have coexisted with humanslonger than the affected (replaced) species intheplaceof their introductionandsubse-quent expansion (Burney 1995/1996, Hierroet al. 2005). Finally, propagules of many in-vasive species are located closer to shippinglanes in their points of origin and in their ini-tial places of dispersion (Hierro et al. 2005)and hence are easily transported often as bal-last (Burney 1995/1996, Crosby 2004, Russell1997).

[Note that not all of these bio-logical invasions have been human medi-ated: For example, because of their superiorswimmingabilities,hippopotami,elephants,and deer hopped fromone island to an-other across open seas during the Quaternary(Burney 1995/1996).] Regardless of the trans-port agent, biological invasions have been theprincipal proximate cause of extirpations andextinctions of native ora and fauna (Burney1995/1996, Myers &Bazely 2003, Pimm1991) whencomparedwithothers suchasoverexploitation(as withextinctions of theCarolina parakeet and the Giant Auk) and lo-cally cascading effects of the removal of singu-larly important species (keystone species) onwhich other species depend.Invasivespeciesareoftentransportedtonew destinations accidentally (Crosby 2004,Myers & Bazely 2003) as in ship bal-last (Crosby 2004, Myers &Bazely 2003,Pilson &Prendeville 2004, Russell 1997,Simberloff et al. 1997), the case, for ex-ample, with red tides (toxic dino-agellates)(Burney 1995/1996), a phenomenon that in-creased signicantly after approximately 1500(Crosby2004). Perhapsjustasoften, how-ever, invasivespecieshavebeenintroducedintentionally (before their invasive features inthe new environment were known) to fullldesired functions, including as ornamentals,windbreaks, scenicbyways, erosioncontrol,fencing, and livestock feed (Beinart & Coates1995, Myers & Bazely 2003, Simberloff et al.1997). Insomecases, thesespeciesarein-dicative of landscapes inhabited and modiedby human societies in ancient times, as withtheKentuckycoffeetree, Americanchest-nut, andbutternut, propagatedatlongdis-tances from their original distribution in pre-historic North America, and the walnut andsweet chestnut in the British Isles, taken therebytheRomansintherstmillenniumAD(Russell 1997).The restorationist (and conservationist)notion that native species in situ are su-periorandpreferabletointroducedspeciesis traceable to nineteenth-century Europeanthinking that conjoined culture and wild-nerness into a single landscape (Hall 2005),such as the German Naturgarten (Wolschke-Bulmahn 2004). Specically regarding diver-sity, goals of restoration ecology that includeeradication of exotic species can be traced toantiquity, with Platos doctrine on the desir-ability of high species diversitythe worldis the better, the more [living] things it con-tains (Glacken 1967)insofar as the richerthe species diversity, the greater the resilienceof the area to biological invasion (Pimm1991;cf. Simberloff 1997). Platofurther thought thestate of nature was only bountiful when ac-tively managed by humans (Hall 2005). Morerecent study of Mediterranean so-called ru-ined landscapes suggests many represent theanthropogenicexpansionof forests richinspecies diversity in the region, not the reverse(Grove & Rackham 2003).Biological invasions have caused re-ductions and extirpations of numerousspecies through mechanisms including directcompetitive exclusion (Burney 1995/1996,Simberloff et al. 1997). In the case of intro-duced pathogens, their success is only miti-gated by the extent to which a host popula-tion survives and can be a reservoir for futureendemic propagation(Newson1998). Thespecies barrier between humans and other an-imals is effectively broken down by diseasesthat are anthropozoonotic (the vector human,infecting other animals), such as tuberculosis,measles, and human herpes virus (Karesh &Cook 2005), and by habitat loss [an extremeexampleofhabitatfragmentation, whichina general sense does not always cause re-ductionsinspeciesdiversity(Fahrig2003)],accounting for changes in relations betweenpathogensandhosts, aswithchronicwast-ingdiseaseofmuledeer, white-taileddeer,andRockyMountainelk(Farnsworthetal.2005).

Avianinuenza (H5N1type A inuenza virus), which has potential tobecome pandemic, is notable for high mor-bidity as well as for having the potential formultiplevectors:wildbirds,housecats,bigcats, chickens, pigs, and humans, all of whichhave human-mediateddistributions andinter-actions (Normile 2005). Scrapie (a prion dis-ease) in sheep jumped the species barrier andbecame mad cow disease in cattle, a strain ofwhich appears to have crossed the species bar-riertohumansasvariantCreutzfeldt-Jakobdisease (Karesh & Cook 2005). Disease ecol-ogytotheextent thatit linkshumansandother biota, by affecting distributions on thelandscape of both, becomes more fully com-prehensible within the temporality of histori-cal ecology (Newson 1998, Turner 2005).The morphology and behavior of invasivebiota may be predictable (they may be weedy,opportunistic,andgeneticallyplasticwithacapacity to mutate rapidly and, in some cases,toinfectotherorganismsandjumpspeciesbarriers), but biological invasions do not nec-essarily all result in net reductions of alpha,beta, or even gamma diversity. Indeed, manyr-species invaded K-dominated environmentsbefore the advent of the Homo migrations outof Africa at the beginning of the Pleistocene,and initial modern humans did not have manyinvasive species other than head lice and a fewothers, none of which were domesticated, totransport withthem(Burney 1995/1996). Thequestion then is how long must a species existina givenenvironment tonolonger be consid-ered invasive? An arbitrary classication forinvasive plants is used in European forestry,wherebyarchaeotypesexistedontheconti-nent before1500andneophytes arethoseplants arriving after 1500; other species ori-gins are simplyunknown, andthe speciesare denoted as cryptogenic (Myers & Bazely2003). Some invasive species in fact functionas keystone species, and even their removalmaynot causeareturntotheuninvadedstate (Myers &Bazely 2003). This is arguablythe case with invasive species that have alteredthe fundamental structural characteristics oflandscapes, suchas melaleuca trees, whichform woodlands in Florida where previouslythere were none, hence altering the distribu-tion of numerous other species of ora andfauna (Schmitz et al. 1997, Simberloff 1997).DISCUSSION ANDCONCLUSIONSOn the basis of the notion that native speciesare more desirable than exotic ones, not onlyfor aesthetics but for reasons related to pro-tecting biotic diversity, efforts in restorationecology have tended to focus on the removaland eradication of invasive species. These ef-fortshavemetwithmixedresults. Restora-tion ecology (applied historical ecology) es-sentially requires the knowledge of referenceconditions of a past state of the landscape toat-tain authenticity (Egan &Howell 2001b, Hall2005, Hayashida 2005, Higgs 2003, Jones2004).Historical ecologycansupplytherefer-enceconditions neededfor authenticityoflandscape reconstruction(Egan&Howell2001a,b, Hayashida 2005, Higgs 2003). Thesourcesvaryandarederivedfromresearchinpaleoecology, ethnohistory, history, andarchaeology (Crumley 1994, 2003; Erickson2003; Hayashida2005; Heckenbergeretal.2003; Kidder 1998; Turner 2005); fromethnography and ethnobiology (Bal ee 1993,Posey 1985, Posey & Bal ee 1989, Rival 2002,Zent&Zent2004); frombiological inven-tory work (Campbell et al. 2006, Erickson &Bal ee 2006, Turner 2005); and from researchon symbols and language. Landscapes, as gar-dens, communicate meaning about their usersand owners in the Peruvian Andes (Finerman90 Bal eeAnnu. Rev. Anthropol. 2006.35:75-98.

Knowledge of archaic culti-gens is retainedinmemory andreectedinrit-ual in Borneo and elsewhere in Southeast Asia(Dove1999). Languagecatalogspaststatesoflandscapesbycurrenttopographicterms(Russell 1997); it also embodies past methodsof resource exploitation, such as agriculturein prehistoric equatorial Africa, reconstructedby historical-linguistic study of living Bantulanguages(Vansina1990). Languageretainsevidence of former economic valorization ofspecies and landscapes, as with the cacao ex-port cycle from the Amazon in the eighteenthcentury, reected in the indigenous borrow-ing of a nonnative termfor cacao even thoughthe tree is native (Bal ee 2003). Marking rever-sals for biota represent a chronology of land-scape transformation inscribed in vocabulary,suchasthechange,inmanyMesoamericanlanguages, in the name for sheep, introducedfrom Spain, to the original name for white-tailed deer, a native forest animal but increas-ingly rare as a result of the invasion of pasturefor sheep grazing, and vice versa (Witkowski& Brown 1983). Historical ecology is inter-disciplinary, and in one of its disciplines, an-thropology, it is clearly intersubdisciplinary.Applied historical ecology may become theholisticengagementofknowledgefromdi-verse disciplines for the benet of human so-cieties and selected biota and landscapes. It isderived from several elds with the objectiveofdeterminingreferenceconditionsofpastlandscapes with the highest degree of authen-ticityfortheperiodchosenforrestoration.The remaining problem, in terms of the ap-plications of historical ecology, concerns po-litical questions as to who will be privilegedin determining the desired time depth (Higgs2003, Jones 2004) and the associated state ofhistorical knowledge(Anderson2001, Hall2005) about the landscapes to be restored.ACKNOWLEDGMENTSFor helpful discussion and suggestion of references, I am indebted to David Campbell, ClarkL.
