Ash dieback in Europe is caused by an invasive alien pathogen originating from East Asia, the helotialean ascomycete fungus Hymenoscyphus fraxineus. This disease first emerged in the early 1990s in NorthEastern Poland, and the pathogen successively invaded most of Europe, in total 32 countries, in the next decades, causing substantial damage and ...

BioScience, 1987
urrently, much public concern and research effort focuses on forest dieback in industrial countries. Factors associated with air pollution, such as acid rain, nitrous oxide, changes in the ozone level, and heavy metal deposition are often considered responsible for tree mortality on both sides of the Atlantic.

Forest dieback in Czechoslovakia
Vegetatio, 1991The article reviews the literature dealing with levels of air pollution in Central Europe and Czechoslovakia particulary in connection with the rate of forest damage and dieback since the fifties. To date 57 percent of forests on an area of 15.000 square km are damaged in Czech republic and more than 40.000 ha of dead Norway spruce forest had to be cut

Perspectives for an Etiology of Stand-Level Dieback
Annual Review of Ecology and Systematics, 1986When trees are dying in large numbers in a forest stand, it is usually assumed they are dying from a disease. Therefore, the study of stand-level dieback has traditionally been the concern of the forest pathologist and pest entomologist. However, stand-level dieback is not always caused by biotic agents, and the term as defined in this paper refers to ...

Dieback and Declines of Urban Trees
Arboriculture & Urban Forestry, 1985AbstractDieback-decline diseases occur when trees, stressed and altered by abiotic or biotic agents, are attacked by organisms of secondary action. The primary stress factors in forests are insect defoliation and extremes of moisture and temperature. In urban situations, drought is probably the most important stress factor.

Narrow-leaved ash is currently most damaged forest tree species in Croatia according to the ICP Forests programme. Damage of crowns can be mostly attributed to pathogenic fungus Hymenoscyphus fraxineus, while damage of roots and stem bases is caused by several pathogenic fungi, including Hymenoscyphus fraxineus, Armillaria spp. and Ganoderma adspersum.
