- In years 2002 and 2003, pairs of test plots were established in pine stands of the 3rd and 4th age classes of selected forest divisions. The crown condition of 25 trees from the main stand was assessed on each plot employing the so called stand method. Damage indices were calculated for each test plot, which were used to assign individual stands to the appropriate damage zone. The presence or lack of statistically significant differences of damage indices was checked and this was referred to the membership of individual stand pairs in damage zones. The proportions of damage zones determined according to two divisions for the 3rd, 4th and, jointly, for the 3rd and 4th age classes in both years of observations were compared.
