In our study, we present partial results of the investigation of height growth within a sixty-five-year period, based on the analysis of data obtained from seven forest management plans in the management plan area of Kostelec nad Cernymi lesy (Czech Republic) and continuous measurements on pilot research plots in the period of 1965-1994. The mutual comparison of mean height growth curves obtained by the curve fitting of the values of empirical data show a dependence on the calendar year. It signifies an increasing height growth trend of both species in the given area.
