Footnotes

aFrom 2007 the data are not comparable with that of the previous years, because the limits of the damage categories changed. The reason for that is the change to the international methodology (ICP Forests) including new damage categories.

cData corrections were made on 2 September 2022. Reason for the error: unplanned revision. The incorrect data were 22.9%.
