Ring Analysis

Tree ring analysis is one of the most useful methods in volume and biomass estimation especially of the conifer trees. Ring width and ring density are important parameters in dendrochronological research. The present research was carried out with the aim of estimating the radial and volumetric growth of the Japanese Cypress trees (Chamaecyperis obstusa and C. pisifera). Destructive method was used while collecting the wood samples from the selected trees. Ring width and ring density were measured using soft X-ray densitometry method using micro-densitometer. Computer programme, developed by the Forestry and Forest Products Research Institute, Japan was used to analyze the ring with and ring density data. The average ring width of the Chamaecyparis spp. was found to be about 3.4 mm at the age of 30 years. However, two types of growth pattern were observed in the trees. Average radial growth was about 5% every year during the first 20 years of the tree age, whereas, the average radial growth was negative during the age of 20–30 years. Average density of the tree rings were increased by about 11% in each height of the trees starting from the ground. Similarly, the stem density decreased by about 3.4% annually along the radial direction from the pith.DOI: http://dx.doi.org/10.3126/banko.v22i2.9197Banko Janakari: A Journal of Forestry Information for NepalVol. 22, No. 2, 2012 November Page: 36-42 Uploaded date: 12/1/2013

AbstractMay-June (MJ) and April-July (AJ) precipitation at Huashan in north-central China has been reconstructed for the period A.D. 1600 to 1988 using tree-ring density and width fromPinus armandii. MJ precipitation (based on ring width and maximum latewood density) calibrated and cross-validated against local instrumental data more strongly than AJ precipitation (based only on ring width). A major drought was reconstructed for the mid- and late 1920s, confirmed by local documentary sources. This drought (culminating in 1929) was the most severe of the 389-yr period for MJ and second most severe for AJ, after an event ending in 1683. Neither reconstruction shows much spectral power at frequencies lower than 1 in 10 yr, but both show concentrations of power between 2.1 and 2.7 yr and 3.5 to 9 yr. There are significant correlations between the two reconstructions and a regional dryness/wetness index (DW) based on documentary sources, particularly at high frequencies. These correlations are focused in the 7.6- to 7.3-, 3.8- to 3.6-, and 2.5-yr periods. Using singular spectrum analysis, quasiperiodic behavior with a period close to 7.2 yr was identified in the MJ precipitation reconstruction and in the DW index based on documents.

Abstract The aim of the present work was to characterize the growth – climate relationship of pines growing in the Szczecin city forests in intensively used recreational areas and to identify the effect of air pollutants emitted by a nearby chemical factory on tree-ring width. Our research area was located in the Głębokie forest complex, which is one of the most frequently visited. The chemical factory Police that produces fertilizers is located at a distance 11 km away from the study plot. The largest emissions of pollutants from the factory in terms of volume occurred in the 1980s and early 1990s. Wood samples were collected from Scots pine (Pinus sylvestris L.) with the Pressler borer from 30 trees and examined using standard dendrochronological methodology. The result was a local chronology of 169 years from 1848–2016. Dendroclimatological analyses indicated that the weather conditions at the turn from winter to spring are the dominant factors influencing radial growth. For example, higher than average temperatures in February, March and April result in a wide tree-ring in the upcoming growth season. Following Nowacki and Abram’s method, we also determined the relative growth change in order to delimit the timeframe when air pollution potentially alters tree-ring width. Due to the lack of data for the period 1848–1945, the increasing and decreasing relative growth could not be linked to specific events. For the period 1944–1972 however, we observed and increase in the tree-ring width, which in this case can be attributed to favorable weather conditions. The final period, 1973–1991, on the other hand showed the strongest decline in annual growth throughout our chronology and this was largely due to the nearby chemical factories, which released huge amounts of pollution into the atmosphere during this period. At present, despite new technologies and a decrease in overall production by the nearby chemical factory, we found a negative trend in ring width dynamics indicating a need for pollutant monitoring and further research.

The Impact

Abstract The main aims of these studies were dendrochronological and mass spectrometric analysis of the impact of climate on tree rings width and stable isotopes composition in pine (Pinus sylvestris L.). The conifers were growing in the vicinity of chemical and nitrogen factories in Kędzierzyn-Koźle (Poland) in the period of time from 1920s to 2012 AD. The combined usage of tree ring width and isotopic composition data provides historic records of the environment changes. These data allows identifying the behavior adaptation of pine growing under pollution stress to climate changes. The incremental rhythm of the studied pine populations was not identical, probably due to their different sensitivities to some climatic factors. This study evidences that the isotopic records in tree-rings α-cellulose may be sensitive bio-indicators of the way that the components of air and water may be changed by the trees in response to the climate changes and anthropogenic effects. The water use efficiency may be strongly correlated with variability of the surface temperature that may be due to increase of CO2 emission.

In this article, the dependence of the sessile oak (Quercus petraea (Matt.) Liebl.) radial growth (tree-ring, earlywood, and latewood widths) on climate (the mean monthly temperature and precipitation totals) was studied in the Majdanpek area, north-eastern Serbia. The growth response of the oak trees to the prevailing climate conditions was dendroecologically investigated, by applying the correlation and response function, as well as by pointer years analysis. The site chronology covered 159 years (1855-2013). We found that latewood and total tree-ring width contain the imprinted positive response to the amount of precipitation in summer months (June and July) of the current growing season. The earlywood width showed no direct dependence on climate data, but it was significantly affected by the previous-year latewood width. Moreover, 40 % of the variation in the latewood width is explained by the earlywood variation in the same season. The temperature was not found to have any significant effect on the growth of oak at the study site. The use of pointer years, determined by applying several calculation procedures, has highlighted previous results, indicating that the precipitation in summer months was the deciding climate factor leading to the occurrence of the years with exceptionally wide or narrow tree-rings and latewood. To enhance our understanding of the response of the sessile oak growth at south-oriented sites with a shallow soil profile to precipitation and temperature variations, and expand the current database and knowledge, future studies should be undertaken.

<p>The aim of this study was to compare the climatic responses of three tree rings proxies: tree ring width (TRW),<br>maximum latewood density (MXD), and blue intensity (BI). For this study, 20 cores of Pinus sylvestris covering<br>the period 1886–2015 were extracted from living non-damaged trees from the Eastern Carpathian Mountains<br>(Romania). Each chronology was compared to monthly and daily climate data. All tree ring proxies had a<br>stronger correlation with the daily climate data compared to monthly data. The highest correlation coefficient<br>was obtained between the MXD chronology and daily maximum temperature over the period beginning with the<br>end of July and ending in the middle of September (r=0.64). The optimal intervals for the temperature signature<br>were 01 Aug – 24 Sept for the MXD chronology, 05 Aug – 25 Aug for the BI chronology, and both 16 Nov<br>of the previous year – 16 March of the current year and 15 Apr – 05 May for the TRW chronology. The results<br>from our study indicate that MXD can be used as a proxy indicator for summer maximum temperature, while<br>TRW can be used as a proxy indicator for just March maximum temperature. The weak and unstable relationship<br>between BI and maximum temperature indicates that BI is not a good proxy indicator for climate reconstructions<br>over the analysed region.</p>

A fuel wood analysis based on the ‘Principle of Least Effort’ helps to decipher the ecological limitations imposed on prehistoric hunter-gatherers. This study is based on botanical identification of wood charcoal from ‘Swedish middle Mesolithic’ archaeological sites dating from between ca. 9650 and 8300 cal. yr BP in northern Sweden, a period when the land was freshly released from ice cover. Charcoal fragments were analysed based on their anatomical and morphological features and anomalies. Tree-ring thickness gives an indication of the growing conditions experienced by woody plants, the tree-ring curvature provides an indication of the diameter of the pieces of wood used for fuel and the percentage of fragments with spiral thickening indicates the importance of compression or tension wood, which is related to branches or trunks stressed by snow burden or wind. Among the main woody species, the assemblages are dominated by Pinus sylvestris with some Salicaceae trees ( Populus, Salix). Large wood pieces including branches were used as fuel. Several taxa were rarely recorded ( Betula, Sorbus, Ericaceae) or not observed ( Juniperus, Hippophae, Alnus) although their presences were expected based on other local palaeobotanical records. Because (1) charcoal of Pinus sylvestris abounds despite not being a good fuel wood and (2) certain consumable or combustible taxa are scarce ( Betula) or are only present at certain sites (Salicaceae), it appears that Mesolithic hunters were not selective when choosing wood for fuel, although wood was not a limiting factor for the first settlers in northern Sweden. Pine tree-ring width range is within the modern range for the same species, indicating growing conditions similar to those experienced today. The results suggest the occurrence of woodland, probably in the lowlands. During the early-Holocene, trees rapidly covered the land after the ice-sheet melted, facilitating the life of Mesolithic hunters following reindeer herds.
