Tree rings from a European beech forest chronosequence are useful for detecting growth trends and carbon sequestration

-Stem analysis process is commonly employed in a wide range of applications of forest importance. We developed a program to compute stem increments in terms of volume, biomass and carbon storage. The stem-analysis process involves the felling of the tree, the extraction of a number of cross-sections from the stem and the measuring of ring-width series on each section. The synchronization of ringwidth series provides a number of tree-and stand-related measures including stem growth pattern, diameter at breast height and tree height growth trend, site-index assessment, timber-quality assessment. Relevant features of the program include: (i) tables and charts can be handled in the "R" environment or exported to any spreadsheet program; (ii) algorithms are independent from the ring width measuring device; (iii) the computation of stem volume, yearly-and mean volume increment is provided as well as the lateral surface area, stem carbon pool, its yearlyand mean increment and associated measurement errors. Forest biomass destructive surveys can usefully apply stem-analysis techniques in order to assess forest past carbon increment trend and set up the basis for non-destructive future carbon surveys. stem analysis / carbon pool / annual carbon increment / error budget / R

“…Different methods of dendrochronological analysis were often used to evaluate the impact of pollution on the potential incremental trees (McLaughlin et al, 2002;Bascietto et al, 2004;Battipaglia et al, 2009;Eckstein and Schweingruber, 2009), A number of studies have investigated: the rate of trees with different degrees of growth reduction to the diameter and height (Kienast, 1985;Schweingruber, 1986;Danek, 2007;Elling et al, 2009;Malik et al, 2012;Crecente-Campo et al, 2010), differences in similarity in radial growth response of trees (Wilczynski, 2006). 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).…”

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.

“…The comparable fall in BAI reported by Piovesan et al (2005b) suggests that this climate-related decline in the growth of F. sylvatica at the edge of its range in Montseny is not an isolated phenomenon, but may be occurring at the southern range edge of this species elsewhere in Europe. F. sylvatica is an increasingly important species for European forestry (Dittmar et al, 2003) and therefore a highly significant species in terms of carbon sequestration (Bascietto et al, 2004). Recent climatic warming has increased the length of the growing season for many species in the Montseny region (Peñ uelas et al, 2002), suggesting a positive growth response to recent climatic changes might be expected for F. sylvatica.…”

Studies on Fagus sylvatica show that growth in populations toward the southern limit of this species' distribution is limited strongly by drought. Warming temperatures in the Mediterranean region are expected to exacerbate drought where they are not accompanied by increases in precipitation. We studied levels of annual growth in mature F. sylvatica trees over the last half-century in the Montseny Mountains in Catalonia (northeast Spain). Our results show significantly lower growth of mature trees at the lower limit of this species' distribution when compared with trees at higher altitudes. Growth at the lower Fagus limit is characterized by a rapid recent decline starting in approximately 1975. By 2003, growth of mature trees had fallen by 49% when compared with predecline levels. This is not an age-related phenomenon, nor is it seen in comparable populations at higher altitudes. Analysis of climate-growth relationships suggests that the observed decline in growth is a result of warming temperatures and that, as precipitation in the region has not increased, precipitation is now insufficient to ameliorate the negative effects of increased temperatures on tree growth. As the climateresponse of the studied forest is comparable with that of F. sylvatica forests in other southern European regions, it is possible that this growth decline is a more widespread phenomenon. Warming temperatures may lead to a rapid decline in the growth of rangeedge populations and a consequent retreat of the species distribution in southern Europe. Assessment of long-term growth trends across the southern range edge of F. sylvatica therefore merits further attention.
