Phenolic Leaf Compounds in Ash Trees (Fraxinus excelsior L.) in the Context of Ash Dieback

Forests
Most ash trees (Fraxinus excelsior) in Germany are infected with Hymenoscyphus fraxineus, the causative agent of ash dieback (ADB). This study investigates the phenolic content of ash leaves to evaluate their potential as indicators for monitoring ADB ...

Evaluating the Potential of WorldView-2 Data to Classify Tree Species and Different Levels of Ash Mortality

Remote Sensing, 2014
Forest disturbances in central Europe caused by fungal pests may result in widespread tree mortality. To assess the state of health and to detect disturbances of entire forest ecosystems, up-to-date knowledge of the tree species diversity is essential ...

Point-of-care diagnostics and resistance phenotyping to combat ash dieback

Frontiers in Forests and Global Change
Non-destructive tree phenotyping for resistance screening and early, presymptomatic disease detection figures prominently among the most important practical limitations inherent in forest health management.

Multiple, single trait GWAS and supervised machine learning reveal the genetic architecture of Fraxinus excelsior tolerance to ash dieback in Europe

bioRxiv, 2023
Common ash (Fraxinus excelsior) is under intensive attack from the invasive alien pathogenic fungus Hymenoscyphus fraxineus, causing ash dieback at epidemic levels throughout Europe.

Evidence of a component Allee effect for an invasive pathogen: Hymenoscyphus fraxineus, the ash dieback agent

Biological Invasions, 2023
Invasive pathogens are a major threat to forest health especially in managed forest with a low diversity of tree species. The dieback of Fraxinus spp. caused by the fungus Hymenoscyphus fraxineus that occurs in Europe is the latest example of pathogen ...

Identification of ash-associated understorey diversity—a lesson from historical vegetation records

Annals of Forest Science
Key message Forest communities historically dominated by common ash (Fraxinus excelsior L.) were characterized by particularly high species richness in the understorey and included a distinct set of vascular plant species statistically associated with ...

Lessons to learn for better safeguarding of genetic resources during tree pandemics: The case of ash dieback in Europe [PDF]

Biological Conservation
Ash dieback (ADB) is threatening populations of European ash (Fraxinus excelsior&F. angustifolia) for more than three decades. Although much knowledge has been gathered in the recent past, practical conservation measures have been mostly implemented at ...

Preliminary genetic barcodes for ash (Fraxinus) species and generation of new wide hybrids

Plants, People, Planet
Societal Impact Statement The world‐wide diversity of ash trees includes genetic information encoding resistance to the ash dieback fungus and the emerald ash borer beetle, which are currently devastating ash populations in Europe and North America.

Identification of damage severity in Fraxinus excelsior L. trees caused by ash dieback using multisensory and multitemporal UAV imagery

Forest Ecology and Management
The extended spread of ash dieback in Europe has far-reaching consequences for Fraxinus excelsior L. populations. The progression of the disease leads to characteristic symptoms, particularly within the tree crowns. To date, assessing the damage severity

Fungal endophytes with anti-fungal metabolites reduce symptoms of ash dieback in Fraxinus excelsior in a greenhouse experiment.

Fungal Biology
European ash trees (Fraxinus excelsior) are threatened by the non-native fungal pathogen Hymenoscyphus fraxineus, which causes crown dieback and root collar necroses.
