First report of Hymenoscyphus fraxineus in Montenegro
time in 2016 during studies on fungus species present on forest tree species within the Biogradska Gora National Park. In August 2016, dieback symptoms were noticed on 4-6 year old ash trees (Fraxinus excelsior) naturally regenerating in a riparian area around Lake Biograd. Samples were randomly collected from 20 symptomatic trees and laboratory analysis (morphological and physiological characterization) confirmed the presence of H. fraxineus. As no symptoms had been observed on ash trees during similar studies in 2013 and 2014, it is supposed that the introduction of H. fraxineus in the Biogradska Gora National Park is recent. It is concluded that further monitoring of the disease within the protected area of Biogradska Gora National Park, as well as in other stands of F. excelsior and F. angustifolia in Montenegro should be carried out.
The situation of Hymenoscyphus fraxineus in Montenegro can be described as follows: Present, only in some areas, first found in 2016 in the Biogradska Gora National Park.
