“…Another benefit of the improved network will be the use of archaeological material in climatological and ecological research. Dendroarchaeological data have the potential to extend existing chronologies farther into the past (Cook et al, 2015; Matheus et al, 2017), informing a broader context of environmental change (e.g., in the development of drought atlases). Other potential advances include analyses of range-wide crossdating and climate sensitivity of longleaf pine.…”

The longleaf pine ( Pinus palustris Mill.) and related ecosystem is an icon of the southeastern United States (US). Once covering an estimated 37 million ha from Texas to Florida to Virginia, the near-extirpation of, and subsequent restoration efforts for, the species has been well-documented over the past ca. 100 years. Although longleaf pine is one of the longest-lived tree species in the southeastern US—with documented ages of over 400 years—its use has not been reviewed in the field of dendrochronology. In this paper, we review the utility of longleaf pine tree-ring data within the applications of four primary, topical research areas: climatology and paleoclimate reconstruction, fire history, ecology, and archeology/cultural studies. Further, we highlight knowledge gaps in these topical areas, for which we introduce the Longleaf Tree-Ring Network (LTRN). The overarching purpose of the LTRN is to coalesce partners and data to expand the scientific use of longleaf pine tree-ring data across the southeastern US. As a first example of LTRN analytics, we show that the development of seasonwood chronologies (earlywood width, latewood width, and total width) enhances the utility of longleaf pine tree-ring data, indicating the value of these seasonwood metrics for future studies. We find that at 21 sites distributed across the species’ range, latewood width chronologies outperform both their earlywood and total width counterparts in mean correlation coefficient (RBAR = 0.55, 0.46, 0.52, respectively). Strategic plans for increasing the utility of longleaf pine dendrochronology in the southeastern US include [1] saving remnant material ( e.g., stumps, logs, and building construction timbers) from decay, extraction, and fire consumption to help extend tree-ring records, and [2] developing new chronologies in LTRN spatial gaps to facilitate broad-scale analyses of longleaf pine ecosystems within the context of the topical groups presented.

Abstract. Our understanding of the natural variability of hydroclimate before the instrumental period (ca. 1900 CE in the United States) is largely dependent on tree-ring-based reconstructions. Large-scale soil moisture reconstructions from a network of tree-ring chronologies have greatly improved our understanding of the spatial and temporal variability in hydroclimate conditions, particularly extremes of both drought and pluvial (wet) events. However, certain regions within these large-scale network reconstructions in the US are modeled by few tree-ring chronologies. Further, many of the chronologies currently publicly available on the International Tree-Ring Data Bank (ITRDB) were collected in the 1980s and 1990s, and thus our understanding of the sensitivity of radial growth to soil moisture in the US is based on a period that experienced multiple extremely severe droughts and neglects the impacts of recent, rapid global change. In this study, we expanded the tree-ring network of the Ohio River valley in the US, a region with sparse coverage. We used a total of 72 chronologies across 15 species to examine how increasing the density of the tree-ring network influences the representation of reconstructing the Palmer Meteorological Drought Index (PMDI). Further, we tested how the sampling date and therefore the calibration period influenced the reconstruction models by creating reconstructions that ended in the year 1980 and compared them to reconstructions ending in 2010 from the same chronologies. We found that increasing the density of the tree-ring network resulted in reconstructed values that better matched the spatial variability of instrumentally recorded droughts and, to a lesser extent, pluvials. By extending the calibration period to 2010 compared to 1980, the sensitivity of tree rings to PMDI decreased in the southern portion of our region where severe drought conditions have been absent over recent decades. We emphasize the need of building a high-density tree-ring network to better represent the spatial variability of past droughts and pluvials. Further, chronologies on the ITRDB need updating regularly to better understand how the sensitivity of tree rings to climate may vary through time.

“…However, the rejection of prospective crossmatches that contain low-matching segments is not hard-and-fast, as it is not unusual for a tree to go through decades of suboptimal response to the annual climatic signal. In fact, depending upon the judgment of the individual dendrochronologist, prospective crossmatches with even multiple low-matching segments can still be accepted as correct (e, g., Matheus 2017). The foregoing extends to low-matchingsegment-containing series against the master chronology, which is further aggravated whenever the sample depth* is relatively low, and there is insufficient common variance to "iron out" some of the "misbehaving" segments.…”

Tree ring disturbance clustering for the collapse of long tree-ring chronologies

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.
