Summary The Influence of Climatic Factors on the Growth and State of Health of our Forests On the experimental area in the Josip Kozarac management unit, Professor Klepac confirmed that the growth volume of the stand of pedunculate oak during the period 1962-67 was 50 percent less than during the period 1950-55. This finding caused the author to investigate the role of climatic factors in this occurrence. The results of this investigation are presented in Table 2. In Table 1, the correlation betwen climatic elements and the ring widths of the oaks in Žutica Forest is presented. |
