    We present a tree-ring based reconstruction of water-year (October–September) streamflow for the Manasi River in the northern Tien Shan mountains in northwestern China. We developed eight Tien Shan spruce (Picea schrenkiana Fisch. et Mey.) chronologies for this purpose, which showed a common climatic signal. The hydroclimatic forcing driving tree growth variability affected streamflow with a three- to four-year lag. The model used to estimate streamflow is based on the average of three chronologies and reflects the autoregressive structure of the streamflow time series. The model explains 51% of variance in the instrumental data and allowed us to reconstruct streamflow for the period 1629–2000. This preliminary reconstruction could serve as a basis for providing a longer context for evaluating the recent (1995–2000) increasing trends in Manasi River streamflow and enables the detection of sustained periods of drought and flood, which are particularly challenging for managing water systems. Several of the reconstructed extended dry (wet) periods of the Manasi River correspond to reconstructed periods of drought (flood) in Central Asia in general and in other Tien Shan mountain locations in particular, suggesting that the analysis of Tien Shan spruce could contribute significantly to the development of regionally explicit streamflow reconstructions.
  • Effects Of Dwarf Mistletoe On Climate Response Of Mature Ponderosa Pine Trees

    Stanton, Sharon; Department of Biology, Portland State University (Tree-Ring Society, 2007-12)
    This research examines the influence of western dwarf mistletoe (Arceuthobium campylopodum) infection on the radial growth response of mature ponderosa pines (Pinus ponderosa) and its effects on dendroclimatic reconstructions. I hypothesize that trees with mistletoe have lower annual growth rates than uninfected trees, but exhibit higher mean sensitivities and stronger relationships between growth and climate variation. I tested these hypotheses using correlation and regression analyses to compare 100-year crossdated and standardized tree-ring chronologies from 26 infected and 29 uninfected trees. I compared both chronologies to climate variation as measured by changes in total precipitation, minimum, mean, and maximum temperature, and the Palmer Drought Severity Index (PDSI). Results show that trees infected with dwarf mistletoe have higher radial growth rates, exhibit greater sensitivity, and respond more strongly to climate variation. Both infected and uninfected chronologies are significantly correlated with the respective climate variables, but exhibit different patterns. The strongest correlations are between infected trees and PDSI for all months tested; significant correlations between uninfected trees and PDSI are limited to May through December lagged from the previous year. These results suggest mistletoe-infected trees are more sensitive to climatic factors than uninfected trees and may be useful for dendroclimatic analyses.
  • Tree-Ring Dating of Sinmu-Mun, The North Gate of Kyungbok Palace in Seoul

    The cutting dates of 10 wood timbers (girders and corner rafters) of Sinmu-mun, the north gate of Kyungbok Palace in Seoul, were determined by the dendrochronological method. Tree-ring chronologies of unknown dates derived from the timbers were crossdated using the graphic comparison method against the dated master chronologies derived from living trees. The living trees for the masters used for this study were Pinus densiflora Sieb. et Zucc. (Japanese red pine), a major timber species for Korean traditional buildings. By comparing the Sinmu-mun samples with the masters from the western Sorak Mountains in central-eastern Korea, the Sinmu-mun samples yielded the cutting dates A.D. 1868, 1869, and 1870/1871. Surprisingly, these dates are 3 to 6 year later than the known date (A.D. 1865) of the Sinmu-mun reconstruction, which was recorded in a historical document ‘Ilsungrok’, the King’s official diary. Since the time that the Sinmu-mun construction date had been questioned, another record was found in the 1872 April issue of Ilsungrok, indicating the rebuilding of Sinmu-mun in the 1870s. Both pieces of evidence, from tree-ring dates and historic records, prove that the rebuilding of Sinmu-mun started after the Fall of 1870, but not later than April 1872. The results prove that tree-ring dating is a precise dating method and it can be applied to archaeological studies on Korean structures.
  • Climate Response Of Dahurian Larch In Secrest Arboretum, Wooster, Ohio, USA

    Moore, Tyler; Malcomb, Nathan; Wiles, Gregory; Department of Geology, The College of Wooster, Wooster, OH 44691, USA (Tree-Ring Society, 2007-12)
    Larix gmelinii (Rupr.) Kuzen. (Dahurian larch) is an important arctic tree-line species in the northern boreal forests of Eurasia. The region’s climate is predicted to change dramatically over the next century, yet little is known about how this species will respond to secular changes in temperature and precipitation. To this end, a ring-width chronology from 25 cores from a stand of seven Dahurian larch trees growing in the Secrest Arboretum, northeastern Ohio, was developed to test the climatic sensitivity of the species in a more temperate climate. The chronology extends from 1931 to 2005 and correlation analysis with monthly precipitation and temperature records shows growth was most strongly limited by summer precipitation until recent decades when sensitivity has shifted to late spring precipitation. The results from this study serve as a contemporary analog to the future growth response of Dahurian larch under warmer and wetter growing conditions in the boreal and arctic regions of Eurasia.
  • Atrics- A New System For Image Acquisition In Dendrochronology

    Levanič, Tom; Slovenian Forestry Institute, Večna pot 2, SI-1000 Ljubljana, Slovenia (Tree-Ring Society, 2007-12)
    We developed a new system for image acquisition in dendrochronology called ATRICS. The new system was compared with existing measurement methods. Images derived from the ATRICS program and processed in any of the available programs for automatic tree-ring recognition are of much higher detail than those from flatbed scanners, as optical magnification has many advantages over digital magnification (especially in areas with extremely narrow tree rings). The quality of stitching was tested using visual assessment - no blurred areas were detected between adjacent images and no tree rings were missing because of the stitching procedure. A test for distortion showed no differences between the original and captured square, indicating that the captured images are distortion free. Differences between manual and automatic measurement are statistically insignificant. The processing of very long cores also poses no problems.
  • Dendroarchaeology Of The Salt Lake Tabernacle, Utah

    Bekker, Matthew F.; Heath, David M.; Department of Geography, Brigham Young University, Provo, UT 84602, USA (Tree-Ring Society, 2007-12)
    We examined tree rings from Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) timbers in the Salt Lake Tabernacle, constructed from 1863–1867 in Salt Lake City, Utah. A seismic upgrade to the Tabernacle initiated in 2005 required the replacement of wooden timbers with steel beams. Our objectives were to 1) determine cutting dates for the timbers to identify logs that may have been salvaged from previous structures, and consequently would have greater historical significance, 2) identify the species and provenance of the timbers, and 3) develop a chronology that could extend or strengthen the existing tree-ring record for environmental and historical applications in northern Utah. We built a 162-year floating chronology from 13 cores and 15 cross-sections, crossdated visually using skeleton plots and verified statistically with COFECHA. Statistically significant (p , 0.0001) comparisons with established chronologies from northern Utah indicated that the Tabernacle chronology extends from 1702–1862. Cutting dates ranged from 1836–1863, with most in 1862 or 1863 and a smaller cluster around 1855. The broad range of cutting dates suggests that some of the timbers were used in previous structures, and that some trees were dead before they were cut. This study provides valuable information for the preservation of historical materials, and increases the sample depth of existing chronologies during the 18th and 19th Centuries.
