Abstract: The authors present results of long term monitoring of beech stems bark necrotic disease of maternal stand in Czech Republic, Slovakia, Poland, Hungary, Romania, Serbia and Bulgaria. Overall, 10,863 beech trees were evaluated at 121 localities. The most trees (6679) were evaluated at 55 localities in Slovakia and 2684 trees at 50 localities in Bulgaria. In each country, we noted a wide interval of values of the beech stems necrotization index (ISN) - e.g. in Bulgaria, from 0.22 to 1.50 and in Slovakia from 0.53 to 1.97. The average value ISN in Slovakia (1.22) was out of all countries surpassed only by a value ISN found out in Czech Republic (1.35). Overall, in Bulgaria, we registered more favourable state of beech bark necrotic disease than in Slovakia. As much as 80% of Bulgarian localities had values ISN < 1.1 compared to only 49.1% of Slovakian localities. At the same time, 12.7% of Slovakian localities had values ISN > 1.5, whilst there was no Bulgarian locality recorded in this interval. We consider Slovakia and Bulgaria the countries where the issue of the beech bark necrotic disease of tracheomycotic type is relatively well processed.
