“…The results obtained in the Curonian Spit NP were also in full agreement with previous studies showing that the concentration of sulphur deposition negatively affects the growth and health of trees (Augustaitis et al 2002, 2010a, 2010b, Augustaitis & Bytnerowicz 2008, Augustaitis 2011. Similar results were expected for the other sites considered in this analysis.…”

© 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 ...

“…For hemi-boreal forests in the northeastern part of Europe, positive effects on forest growth and wood production have been reported [2,11]. More specifically, for Lithuania, the increase in air temperature, precipitation amount, and nitrogen deposition during the vegetative period, and reductions in air SO 2 , surface ozone concentrations, and sulphur and heavy metals deposition since the late 1970s have been associated with the rapid increase in the growth-intensity of Norway spruce, moderate increase in the growth-intensity of Scots pine, and minimal growth increase of birch species [12][13][14][15][16]. Increasing disturbance risks may have adverse effects [2,17,18].…”

Research Highlights: Validating modelling approach which combines global framework conditions in the form of climate and policy scenarios with the use of forest decision support system to assess climate change impacts on the sustainability of forest management. Background and Objectives: Forests and forestry have been confirmed to be sensitive to climate. On the other hand, human efforts to mitigate climate change influence forests and forest management. To facilitate the evaluation of future sustainability of forest management, decision support systems are applied. Our aims are to: (1) Adopt and validate decision support tool to incorporate climate change and its mitigation impacts on forest growth, global timber demands and prices for simulating future trends of forest ecosystem services in Lithuania, (2) determine the magnitude and spatial patterns of climate change effects on Lithuanian forests and forest management in the future, supposing that current forestry practices are continued. Materials and Methods: Upgraded version of Lithuanian forestry simulator Kupolis was used to model the development of all forests in the country until 2120 under management conditions of three climate change scenarios. Selected stand-level forest and forest management characteristics were aggregated to the level of regional branches of the State Forest Enterprise and analyzed for the spatial and temporal patterns of climate change effects. Results: Increased forest growth under a warmer future climate resulted in larger tree dimensions, volumes of growing stock, naturally dying trees, harvested assortments, and also higher profits from forestry activities. Negative impacts were detected for the share of broadleaved tree species in the standing volume and the tree species diversity. Climate change effects resulted in spatially clustered patterns-increasing stand productivity, and amounts of harvested timber were concentrated in the regions with dominating coniferous species, while the same areas were exposed to negative dynamics of biodiversity-related forest attributes. Current forest characteristics explained 70% or more of the variance of climate change effects on key forest and forest management attributes. Conclusions: Using forest decision support systems, climate change scenarios and considering the balance of delivered ecosystem services is suggested as a methodological framework for validating forest management alternatives aiming for more adaptiveness in Lithuanian forestry.

Changing climatic conditions, increased length of growing season, competition, genotype and pollution are the most important factors for tree productivity and health. That is why only by knowing the impact of these factors on trees we can evaluate and change sylvicultural treatments that are important for the health and productivity of forest in Lithuania. The aim of the present study was to detect the significance of the competition index vs. genotype of Scots pine trees on their reactions to changes in meteorology and air pollution. Tree health, dendrometric parameters and stem basal area increment were chosen as response variables to meet the objectives of the presented study. The investigation was carried out at Scots pine genetic stand located in Aukstaitija national park, Vaisniunai district. Data on meteorology and air pollutants were obtained from ICP Integrated Monitoring Station located there. Genetically related individual groups in the stand were established by the neutral part of the genome of short repeated DNA sequence length polymorphism markers. Trees of distinctive short repeated sequences allele frequencies were grouped by Bayesian cluster analysis methods. Four genetically similar tree groups were separated in the monitored stand based on significance of ΔK value. Seven competition indices were used to determine the competition intensity effect on the tree increment and their dendrometric parameters including crown condition. The obtained results revealed that trees which demonstrated the most intensive BAI formation, best crown condition and the most significant reaction to changes in meteorology and air pollution comprised one tree genetic group while trees with adverse characteristics the second. Notwithstanding this competition intensity had the most significant effect on BAI formation.
