4.13 Hungary
In 2009, the forest condition survey based on the 16 x 16 km grid including 1 872 sample trees
on 78 permanent plots in Hungary. The assessment was carried out during the period of July –
August. 86.3% of all assessed trees were broadleaves, 13.7% were conifers.
The overall health condition of the Hungarian forests improved compared to 2007, when the
assessment method was the same one. The share of trees without visible damage increased from
51.8% to 54.8%. The mean defoliation of all species was 19.0%, i. e. by 0.3 percent points
slightly lower than in 2007.
The percentage of all tree species in defoliation classes 2-4 (moderately damaged, severely
damaged and dead) was in 2009 lower than in 2007 (18.4% and 20.7%, respectively). The ICP
