Joint project Genetics and Breeding of Ash – subproject 1: Selection, characterisation and preservation of vital ash trees and investigation of genetic causes of resistance to ash dieback
Project
Project code: TI-FG-08-PID2364
Contract period: 01.07.2020

Purpose of research: Networks and research co-ordination
Preservation of common ash (Fraxinus excelsior L.) through selection, characterisation and conservation of vital plus-trees and investigations of genetic cause of resistance to ash dieback.
Since it was first detected in Germany in 2002, ash dieback caused by the fungus Hymenoscyphus fraxineus (asexual stage: Chalara fraxinea) has spread throughout Germany and large parts of Europe. The occurrence of the common ash in the German forest is continuously declining drastically. In addition to dramatic financial losses for forestry operations due to deterioration in wood quality, mortality of the trees and increased expenditure for controls and maintenance (road safety obligation), the future of the common ash is uncertain, especially since new plantings are not recommended. Since the occurrence of ash dieback in Germany, intensive research has been carried out. This is done by various research institutions, partly linked to an exchange of experience at European level. The fact that the research efforts in the individual federal states are based on the use of similar methods but different scales proves to be an obstacle. This makes it difficult to compare the results and to derive uniform and pooled recommendations for action. The need for a coordinated approach to deal with ash dieback was unanimously expressed by experts in a multidisciplinary workshop held at the suggestion of the BLAG-FGR (Fussi et al. 2017). This workshop provided valuable suggestions for the development of a national strategy on how forest practice, politics and research can work together and effectively for ash trees. The overall goal of the project is a coordinated approach against ash dieback involving all relevant disciplines.
