Forest dieback research program

Overseeing a research program focused on untangling the causes of tree dieback

The NSW Environmental Trust engaged the Commission to oversee the delivery of a research program focusing on the causes of mass eucalyptus tree mortality or dieback. This $1 million program will support research projects that inform the effective management of risks to the environment and economy posed by dieback.

The extent, frequency and intensity of tree dieback is increasing globally, across Australia and within NSW – from the Monaro plains, the Kosciusko Alps to the north coast of NSW. Such events pose a significant risk to ecosystem services that support community values such as biodiversity, water and timber resources, tourism, and cultural and spiritual values.

We will update this website with news, or follow our LinkedIn page.

Eucalyptus Dieback Symposium 2022

We oversee the dieback research program to ensure it provides robust and practical evidence to support decision making for policy and adaptive management of forests. Our key role is to convene forums with researchers, forest managers and other stakeholders and disseminate information.

We partnered with the Australian National University to host the Eucalyptus Dieback Symposium in April 2022. The symposium attracted over 120 delegates including academics, Traditional owners, industry, land managers and environmental groups.

Researchers engaged by the program presented an overview of the research project and progress to date. The symposium helped forge a common understanding across the different projects and identify opportunities for collaboration.

Dieback research program commences

We recently hosted the first annual researchers forum for the program online. The expert dieback panel, including Professor Ros Gleadow, Mr Bradley Moggridge and Professor Hugh Durrant-Whyte (chair), met with researchers from the Australian National University, CSIRO, Macquarie University, University of New England and Western Sydney University.

Eucalyptus dieback is a complex phenomenon. The program aims to encourage researchers to collaborate across different research fields. Working together in this way, will help identify the root causes of dieback and propose interventions that land managers can adopt.

At the forum, researchers presented their projects to help forge a common understanding, identify synergies and opportunities for collaboration. We will continue to work closely with the researchers to facilitate collaboration, ensure mutual benefits are realised and research findings can ultimately be translated into practical land management outcomes.

We will soon post short videos to introduce and explain the research projects.

New research announced

We provided advice to the Trust on dieback research priorities in 2020 (see box below). The Trust has now awarded grants to leading research institutions.

  • Australian National University - Climate and dieback resilience of tableland and mountain eucalypt species of southeast Australia and Environmental drivers, landscape determinants and control of snow gum dieback
  • CSIRO Land and Water - Untangling the role of mycorrhizal mutualisms in eucalypt dieback to enhance revegetation outcomes
  • University of New England - Causes projections and reversal of eucalypt decline and dieback on the New England Tablelands
  • Macquarie University - Characterising the (a)biotic soil factors associated with bell miner associated dieback in eastern NSW
  • Western Sydney University - Determining the physiological underpinnings of eucalypt dieback in New South Wales

The expert dieback panel chaired by Professor Hugh Durrant-Whyte will work closely with the researchers to identify synergies between the research activities and ensure that the outcomes of research inform evidence-based landscape management. We will engage stakeholders and general community on the research and deliver practical advice for future management.
