| : | In 2007, 2.14 million m3 of wood were infested by bark beetle. This means a slight decrease of bark beetle damage compared to the year before. However, the record level of 2 million m3 has been exceeded the fifth consecutive year. Due to the massive wind throw from gales early in 2008, bark beetle gradation will remain a topical issue. Seven federal provinces joined the Austrian bark beetle monitoring system consisting of approximately 170 pheromone traps. The flight activity and especially the flight maxi-mum differed considerably. However, the flight showed a very consistent pattern starting early again, as expected. |
