Diseases of narrow-leaved ash in Croatia - present status

According to the crown defoliation monitoring data as a part of the ICP Forests program, narrow-leaved ash is currently the most damaged forest tree species in the Republic of Croatia, with more than 70% of trees with significantly defoliated crown in 2016. Research conducted so far confirmed the presence of pathogenic fungus Hymenoscyphus fraxineus in the crowns of majority of symptomatic trees and also in roots of affected trees, but in much lower frequency. Rot causing fungi, such as Armillaria spp. were also found in the roots of declining trees.
