The variability of tree-ring width series provides information about environmental changes during the long period. By matching the pattern of wide and narrow tree rings (crossdating) it is possible to find the exact year of formation of each tree. The recovery and development of the stand due to disturbances (thinning, fire, ditching, insect outbreaks, drought, etc.) can be reconstructed using dendrochronological methods.
It is possible to study the growth of coniferous and several deciduous species by using tree ring dating. Tree ring width measurement data enable to estimate the tree’s yearly increment and the stand growth. Based on stand increment data thinning and other management works of stands can be planned. It is possible to examine the growth of conifers and several deciduous trees on the basis of tree rings. Measuring the width of the tree rings allows to determine the annual increase in one tree and also calculate the growth of stand. Thinning and final cutting are planned based on the growth of stand.
