ABSTRACT

In the paper we proposed a methodology to distinguish the phases of the tree growth in thickness of an English oak in the past century based on the ring chronology. We analyzed northern, eastern, southern and western tree ring increments using both the statistical modeling and a taxonomic method. Each step of the methodological procedure was described in the paper and the results were displayed graphically in line plots via a dendrogram and set in a table. To familiarize the Reader with the chosen methodology, some general notes over the approaches were added to the text. In the analysis, three phases of the tree thickness growth in the examined monumental English oak in the 20^th century were set up statistically. The average-annual increments for these phases were calculated and plotted. The appropriateness of this technique for a practical use in dendrochronology was concluded finally and its wider application suggested.

Key words: growth in thickness, dendrochronology, Bayesian modeling, taxonomy, growth phase.
