Storm/Beetle-infestation/Drought damages

Damaged wood balance of Central Europe and Italy

Article by Gerd Ebner, translated by Susanne Höfler | 20.12.2018 - 11:26

Germany saw a damaged wood accrual of around 27 million sm³ this year. Storm Friedericke threw 17.1 million sm³ and the dry summer caused another 10 million sm³ of damaged wood. With this, the damaged wood accrual in Germany makes for 50% of the country's cutting volume.

Czech Republic confirmed last week the accrual of 20 million sm³ of beetle-infested wood this year with an additional ~3.8 million sm³ due to storms early in the year.

Italy saw 13 million sm³ of damaged wood due to storm Vaia which roughly equals the cutting capacity of one year.

As for Austria, around 7 million sm³ of damaged wood are suspected half of which is due to beetle-infestation and storms.
