“…In some cases, temperatures of autumn months (September, October) of the previous year had a dramatic impact on tree radial increments. In contrast, the effect of precipitation was less pronounced (Juknys et al , 2003. The results obtained here are in full agreement with previous recent analyses in this area and revealed no significant negative effect of the meteorological parameters considered on pine increments.…”

© iForest -Biogeosciences and Forestry IntroductionAnnual tree-rings provide a valuable source of environmental information and have been widely used throughout the world to document past forest conditions (Martin-Benito et al. 2011). Parameters related to the annual stem increment are extremely reliable indicators of general forest health and stability (Cook & Kairiukstis 1990). Tree rings provide unique possibilities for the retrospective assessment of growth rates over an extended period of time . Modern tree-ring analysis methods were developed at the beginning of the 1980s, when forest damage was recognized as a serious and widespread regional problem (Eckstein 1985, Cook 1987a, 1987b, Innes & Cook 1989, Schulze 1989. However, a few years later an apparently opposite view on Europe's forest conditions was presented by Spiecker et al. (1996), based on 22 growth studies from 12 countries. The results revealed a considerable increase in forest growth over central Europe (Solberg et al. 2009).Many potential causes for the increase in net primary productivity have been proposed, even though forest health was simultaneously deteriorating. The relative importance of different factors has been difficult to assess because of a multitude of interacting stresses affecting trees throughout their lifetimes (Makinen et al. 2001). Despite this, the main factors for the enhanced growth rates were attributed to increases in the photosynthetic rate, the length of the growing season and the leaf area index (Hyvonen et al. 2007, Boisvenue & Running 2006. Meteorological variation had a major response to these changes (Becker 1989, Innes 1994, Spiecker et al. 1996, Raitio 2000.Our earlier investigations revealed that acidifying pollutants mainly resulted in changes in the rate of tree crown defoliation vs. tree stem increment when the effect of crown defoliation on increment was considered (Augustaitis & Bytnerowicz 2008).In this study, we attempted to detect the effects of acidifying pollutants on stem increment after taking into account the effect of meteorological parameters. Therefore, this study aimed to analyse recent changes in meteorological variables, air pollution, and acid deposition to identify the cause of changes in the stem annual increment of over-mature, pre-dominant healthy pine trees. Material and methodsIn 2010 we assessed tree conditions within national parks (NP) in different regions of Lithuania: Curonian Spit, Zemaitija and Aukštaitija NPs. These three parks are located at a seaside site, in western and northeastern Lithuania, respectively (Fig. 1). A hundred of predominant pine trees were selected matching the following characteristics: age exceeding 120 years, diameter at breast height larger than 50 cm, upper crown taller than the general level of the canopy, no visible crown or stem damage, healthy status (defoliation 0-15 %). Moreover, trees were selected within permanent observation plots already monitored by different methodologies: in Curonian Spit NP plots were established based on UN ECE Forest ...

“…Scientific literature reviews have shown that, the size of reduction also depends on the distance from the source of pollution, directions prevailing winds and area orography (Krąpiec and Szychowska Krąpiec, 2001;Juknys et al, 2003Juknys et al, , 2014Wilczyński, 2006;Elling et al, 2009;Malik et al, 2012;Rydval and Wilson, 2012;Bošela et al, 2014).…”

“…It affected on major limiting factors that controlled the functioning of many ecosystems (Vitousek et al, 1997), the condition of forests and trees physiology (Breymeyer, 1998). Pine (Pinus silvestris L.) has been used in bio-monitoring studies (De Vries et al, 2000;Lombardo et al, 2001;Juknys et al,, 2003;Wilczyński, 2006;Pearson et al, 2006;Danek 2007;Sensuła et al, 2011aSensuła et al, , 2011bSensuła and Wilczyński, 2017). However there is still a lack of data concerning the environmental changes in the most industrialized part of Poland over the last century.…”

Variations of tree ring width and chemical composition of wood of pine growing in the area nearby chemical factories

This study reports the variation of tree-ring widths and annual variation of concentration of metals (Na, Mg, Fe, Ni, Cu, Zn, Pb) in pine growing nearby chemical factories. The conifers (Pinus silvestris L.) investigated in this study covered the time span from 1920s to 2010 AD. Tree-ring widths were measured, dated and rechecked using the COFECHA. Radial trace-element profiles were determined by Laser Ablation Inductively Coupled Plasma Mass Spectrometry. The combined usage of tree ring width and chemical composition of wood provides historic records of anthropogenic impact on the environment and allows identifying the behavior adaptation of trees to the pollution. Data of pine tree cores collected from the sites nearby chemical factories show increasing levels of pollution linked to the increasing of industrial activities in Poland and subsequent dust fallout around the site. This study evidences that tree rings can be used as archives of past environmental contamination.

“…Each POS (see Tab. 1 for detailed characteristics) initially included 12 circular sample plots with on average 15-20 trees in each plot, i.e., about 150-200 sample trees per stand (Juknys et al 2003, Augustaitis & Bytnerowicz 2008). In the current study, data from 46 sample plots representing middle aged (age 65 years) and over mature (age 170 years) stands were used - Fig.…”
