“…Ten or twenty subfossil trees from a single location could make a site submaster(*) chronology that is 400-800 years length (Baillie 1995), and a single farm in Ireland could yield 50 subfossil trees that coalesce into a site submaster chronology that is 500-1,000 years long. (Baillie 2009). Eventually, such submaster chronologies became crossmatched with each other [as done, in preliminary fashion, in Figure 6], and then merged.…”

The Disturbance-Clustering hypothesis, first introduced here, posits that geographically-demarcated subtly-perturbed tree rings had induced the affected trees to crossmatch not in accordance with climatic signals, as is assumed in conventional dendrochronology. They instead crossmatch only within a geographic cluster of like-perturbed trees, and not with those of other clusters or with any of the remaining unaffected climatically-governed trees. During chronologybuilding, these clusters became connected with each other, into an artificially-long chronology, by means of rarelyoccurring fortuitously-crossmatching "bridge" series. An experiment involving fifteen ostensibly heterochronous ancient trees graphically supports this hypothesis. Merely one-per-decade individual-ring perturbations induce all fifteen series to form a self-clustering, robust false master chronology (common variance), moreover to which each series crossmatches to an almost-entirely-convincing degree (nearly all featuring all the important statistics, and including segment-by-segment correspondence of the curves). Significantly, and as experimentally demonstrated in this paper, at least 3 of every 10 disturbances can be omitted in some series, and a robust master chronology still develops. What's more, the construction of the master chronology is not dependent upon the presence of any series that has the full complement of disturbances. Clearly, modestly-disturbed series could adequately have served as the "core" of a cluster of disturbed trees, just as required by the Disturbance-Clustering hypothesis. Furthermore, the previously-introduced now-called Migrating-Disturbance Hypothesis does not require a literal repetition of events in time. A lateral movement of disturbances over centuries is sufficient, as is illustrated. The Swedish and Finnish (Lapland) long Scots pine chronologies have a number of internal discontinuities. While not invalidating the chronologies, these discontinuities provide possible clues to their deconstruction.

“…In this way, it is possible to build annual tree-ring width chronologies consisting of numerous tree-ring series from different sources with overlapping lifetimes of the trees (Figures 2, 7). These chronologies cover several centuries to millennia (e.g., Becker and Giertz-Siebenlist, 1970;Hollstein, 1980;Becker, 1993;Grudd et al, 2002;Friedrich et al, 2004;Baillie, 2009;Nicolussi et al, 2009;Seim et al, 2012) and serve as reference chronologies for dendrochronological dating. The quality of a reference chronology strongly depends on high sample replication, which should ideally be equally welldistributed over time.…”

“…Annually resolved and absolutely dated millennia-long treering width chronologies from living and relict wood have been developed in Europe for the Austrian Alps (9111 years; Nicolussi et al, 2009), northern Germany (8000 years; Leuschner et al, 2002), Ireland (6939 years; Baillie, 2009), northern Sweden (7400 years; Grudd et al, 2002), and Finish Lapland (7519 years; Eronen et al, 2002). The initial "Holocene Oak Chronology" by Becker (1993), has been revised and extended by the "Preboreal Pine Chronology" (Spurk et al, 1998;Friedrich et al, 1999Friedrich et al, , 2004.…”

Human evolution was strongly related to environmental factors. Woodlands and their products played a key role in the production of tools and weapons, and provided unique resources for constructions and fuel. Therefore wooden finds are essential in gaining insights into climatic and land use changes but also societal development during the Holocene. Dendroarchaeological investigations, based on tree rings, wood anatomy and techno-morphological characteristics are of great importance for a better understanding of past chronological processes as well as human-environment-interactions. Here we present an overview of the sources, methods, and concepts of this interdisciplinary field of dendroarchaeology focusing on Europe, where several tree-ring chronologies span most of the Holocene. We describe research examples from different periods of human history and discuss the current state of field. The long settlement history in Europe provides a myriad of wooden archeological samples not only for dating but also offer exciting new findings at the interface of natural and social sciences and the humanities.

“…Pośrednie dane o dawnym klimacie i środowisku możliwe są do odczytania oraz datowania przy wykorzystaniu różnych źródeł pośrednich, takich jak jeziorne warwy, pyłki roślin, czy też lodowe rdzenie, jednak słoje drzew powstające co rok, dzięki analizie dendrochronologicznej, zapewniają najwyższą precyzję i dokładność datowania. Warto zaznaczyć, że w chyba powszechnie znanej (przynajmniej z nazwy) metodzie datowania radiowęglowego dokładnie wydatowane dendrochronologicznie pojedyncze słoje stanowią źródło materiału porównawczego, a także wykorzystywane są w kalibrowaniu krzywych 14 C (Baillie 2009;Becker 1993).…”
