Integrating ecological forecasting tools and cutting-edge field data methods to predict the probability and severity of ash dieback across Ireland.
Background
Ash dieback, caused by Hymenoscyphus fraxineus, poses a serious threat to ash (Fraxinus excelsior) across Europe, including Ireland. The disease is affecting a large proportion of ash trees and subsequently the many species of plant, fungi, lichens and animals associated with ash-dominated habitats.
The E-Path project combines field observations with molecular approaches to improve understanding of disease development and host response in ash. The project aims to generate data that can support monitoring, management and long-term conservation of ash in Ireland.
Aim and objectives of the project
E-Path aims to improve understanding of tolerance and dieback disease development in ash populations by combining field observations, remote sensing and molecular analysis. This is a collaborative project with Dr Silvia Caldararu and Dr Dheeraj Rathore, Teagasc.
The project objectives include:
- Implement extensive field campaigns at selected sites across Ireland to collect biotic and abiotic data, including infection symptoms, tree physiological traits, and environmental parameters. This will also involve integrating the observations from ground surveys with remote sensing data to enable scaling from individual trees to stand-level assessments.
- Apply molecular techniques, including genotyping and quantitative PCR (qPCR), to quantify pathogen presence and load across diverse ash populations. These data will be compared with phenotypic measures of tree health.
- Utilize drone-based imaging to monitor tree canopy condition and detect potential symptoms of ash dieback at larger spatial scales.
- Engage with forest managers, policymakers, and stakeholders to share project findings and explore how emerging insights may support monitoring and management strategies.
Funding
Funded jointly by the Environmental Protection Agency (EPA) and the Department of Agriculture, Food and the Marine, in Ireland, through the Teagasc Walsh Scholarship Programme in partnership with Trinity College Dublin, Botany Department, Ireland
