    A juniper (Juniperus przewalskii Kom) tree-ring width chronology has been developed from the western-most forest of the Qilian Mountains. Our analyses demonstrate both temperature and precipitation have significant effects on tree growth and that both should be considered in climate reconstruction. Thus a regional drought history (A.D. 1855–2001) is reconstructed by calibrating with a linear interpolation through four Palmer Drought Severity Index (PDSI) grid values nearest the sampling site. Our reconstruction extends the drought history of this area and also reveals that the most severe drought occurred in the 1920s. In the context of the drought history of western China, this extreme drought between 1925–1931 is consistent over a large surrounding region of Northwestern China. Multi-taper spectral analysis reveals the existence of significant 40- to 46-year, 29-year, and 2.1- to 3-year periods of variability. Overall, our study provides reliable information for the research of past drought variability in the Qilian Mountains, Northwestern China.
  • Dendroclimatological Investigations Of Sea Buckthorn (Hippophae Rhamnoides) And Reconstruction Of The Equilibrium Line Altitude Of The July First Glacier In The Western Qilian Mountains, Northwestern China

    Radial growth characteristics of a high-elevation shrub species, sea buckthorn (Hippophae rhamnoides), were investigated at four sites in a river valley at altitudes ranging from 3,333 to 3,820 m a.s.l. close to the terminus of the July First Glacier in the western Qilian Mountains of northwestern China. Radial growth of the sea buckthorn was significantly and positively correlated with the mean monthly temperature in June of the current growing season. Based on the fact that fluctuations in the shrub’s radial growth and the glacier’s equilibrium-line altitude (ELA) are affected by climatic variables, a tree-ring width chronology of the four sites was used to reconstruct the ELA from 1950 to 2003. The resulting ELA model explained more than 55.3% of the variance in the ELA of the July First Glacier series. On a decadal time scale, the cumulative-departure curve of the reconstructed ELA series showed an increasing trend from the 1950s to the mid-1960s, followed by a descending trend from the mid-1960s to the mid-1970s. The ELA appears to have remained stable from the mid-1970s to the mid-1990s, but has displayed dramatic variations during the past decade.

    ¹⁴C wiggle-matching was applied to two wood samples closely related to geological and archaeological events with associated dendrochronological dates, to demonstrate the accuracy of ¹⁴C dating with accelerator mass spectrometry (AMS). Wiggle-matching on charred wood with bark, excavated from a pyroclastic mud-flow deposited by the huge 10th Century eruption of the Baitoushan Volcano, revealed the eruption age as cal A.D. 935 +8/-5 with 95% confidence. This date is consistent with the eruption age of A.D. 912 to A.D. 972 estimated by dendrochronology on two wooden boards that had clear stratigraphical connections to the B-Tm tephra deposit in Japan, an ash fall layer formed by the eruption of the Baitoushan Volcano. The date is also consistent with an A.D. 937–938 date estimated by the analysis of varved sediments from Lake Ogawarako in Aomori prefecture. The other wooden board collected from the Mawaki archaeological site in Ishikawa prefecture was wiggle-matched as 783 +13/-11 cal B.C. with 95% confidence, which is consistent with the dates of 830 cal B.C. to 759 cal B.C. obtained for seven wooden poles from the same wooden structures as the wooden board. These results are highly encouraging for obtaining accurate dates on wood when dendrochronology cannot be used.
  • Tree-Ring-Derived Precipitation Records From Inner Mongolia, China, Since A.D. 1627

    Two Chinese pine (Pinus tabulaeformis) tree-ring width chronologies up to 375 years long were used to reconstruct rainfall from February to early July for the Wu Dangzhao region and from February to mid-July for the La Madong region, Inner Mongolia, China. The predictor variables account for 44.3% and 42.7% of the variance in precipitation, respectively. Both historical records and two other tree-ring based precipitation reconstructions from the environmentally sensitive zone (the northern Helan Mountain range and Baiyinaobao) confirm our results. After applying a 10-year moving average, the trends of four tree-ring based precipitation reconstructions vary synchronously. Periods with below-normal precipitation occurred during the 1720s–1730s, 1740s–1750s, 1790s, early 1810s, late 1830s–1860s, 1880s–1910s, late 1920s–1930s and after the late 1960s–early 1970s. Periods with above-normal precipitation occurred in the 1760s to early 1770s, 1820s to early 1830s, 1870s–1880s, early 1920s, 1940s to early 1960s, and 1990s. The late 1920s period was the most severe drought over a broad area in north China in the last 375 years. In contrast, the wettest period was in the late 1990s.

  • Dendrochronology And Past Human Activity- A Review Of Advances Since 2000

    Čufar, Katarina; Department of Wood Science and Technology, University of Ljubljana (Tree-Ring Society, 2007-06)
    Since 2000, important advances have been made worldwide in the dendrochronology of wood associated with past human activity and cultural heritage. This review summarizes this recent progress in regions with a longstanding tradition of using tree-ring methods, such as Europe and the USA, as well as others such as Asia where developments have been particularly rapid in recent years. The oldest wood generally originates from archaeological sites and the largest amount of wood for research comes from historical structures such as monumental and vernacular architecture. In addition to construction wood, wooden doors, ceilings, furniture, objects of art (such as panel paintings and sculptures), Medieval books, musical instruments and boats can also be utilized. Dating is the first and crucial step of the research and is often difficult even in regions where dendrochronology has a long history of use. In addition to absolute dates, dendrochronology has provided extra information that has enhanced historical knowledge from other sources. Behavioral and environmental inferencing and dendroprovenancing are becoming major areas of research in regions with well-developed networks of reference chronologies and active cooperation among laboratories. The online Bibliography of Dendrochronology and information from conferences have been indispensable in this compilation, because much work related to dendrochronology in cultural heritage is still published in ‘‘gray’’ literature, making it difficult to access.
  • A Modified Increment Borer Handle For Coring In Locations With Obstruction

    Brown, Peter M.; Rocky Mountain Tree-Ring Research, Inc. (Tree-Ring Society, 2007-06)
    A simple modification to a standard increment borer handle is described that enhances use of the borer in situations where obstructions to the rotation of a normal handle prevents utilization of the full length of the borer. The modification, informally called the ‘‘Quad-B’’ (Brown’s bent boomerang borer handle), involves bending both sides of the handle to ~35–40° angles. Some potential uses of the modified handle are described.
