UN/ECE ICP Forests in Croatia - a review of crown condition in the period 1998 - 2007

The assessment of crown condition in Croatia has been conducted since 1987, according to the methods and in cooperation with the International Cooperative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests). In this paper the data on crown condition of forests in Croatia on the 16 x 16 km network of bioindication plots is presented for the 10-year period 1998-2007, separately for all species, broadleaves, and conifers. The crown condition of three most prominent tree species in Croatia, Pedunculate oak (Quercus robur L.), Common beech (Fagus sylvatica L.) and Silver fir (Abies alba Mill.) are presented in comparison with the results of European assessments. The percentage of moderately to severely damaged trees in Croatia does not fluctuate significantly in the research period. While the damage of oak and beech is higher in Europe, silver fir is more damaged in Croatia.
