Název v původním jazyce

Impact of climate change on growth dynamics of Norway spruce in south-eastern Norway

Popis výsledku v původním jazyce

The ongoing climate change may have a distinct effect on Norway spruce growth, one of the most important tree species in European forest management. Therefore, the understanding and assessment of climate-growth relationship can help to reveal relevant patterns in temporal variability that may result in lower tree vitality and decline. The main objective of our study was to evaluate the long-term climate-growth variability of Norway spruce in south-eastern Norway, at the northern edge of the temperate zone. We sampled in total 270 dominant and co-dominant trees from 18 plots in south-eastern Norway. We analysed stem cores and evaluated crown condition parameters to assess the retrospective tree growth and vitality. Despite considerable differences in the crown parameters, high similarity among tree-ring width (TRW) series allowed compiliing the regional tree-ring width chronology. Correlations between TRW and climate parameters showed temporal instability in their relationship during the period 1915-2012. While we did not detect any significant relationships between TRW and climate parameters in the first half of the study period (1915-1963), a significant correlation between TRW and spring precipitation was observed for the period 1964-2012. This shift appeared concurrent with temperatures reaching above-average values compared to the average of the climate normal period 1961-1990.
