Response of Trees on Climate Extremes in Uneven-Aged European Beech Stand

Abstract

Climate change is a major challenge for the whole planet, and consequently for the European forestry in the 21st century. Climate change and climatic extremes contribute to the reduction of growth and increment, and forests mortality. In European beech forests in Serbia there still have not been observed massive mortality, as it is the case with other species. The aim of this study was to explain how climate factors affect the growth and increment of uneven-aged European beech stand in Western Serbia, on the mountain Boranja. Samples were taken from the mountain Boranja in Western Serbia. Samples were sampled from the trees that grow in uniform habitat conditions. Sampled were 15 dominant trees. Cores were taken with Pressler’s borer from two opposite sides of the tree at breast height. Samples were air-dried and sanded with sandpaper, until the annual rings were deeply polished. Samples were scanned and measured using WINDENDRO. Using visual comparisons on the screen with PAST software two opposite increments cores were merged for each tree and cross-dated. Basic statistical parameters were calculated using the software Arstan. Statistical analysis were performed inR. We came to the conclusion that high amount of precipitation in July of the current year positively affect the growth of beech in Istočna Boranja (Serbia).
