Episode #20: Eucalypts Spotlight Biosecurity Failures

For more than 100 years, eucalypts—woody plants that range in size from shrubs to trees—have been transported from their natural ecosystems in Australia to plantations across the globe. This unique history provides a novel lens for viewing the spread of pathogens and may shed light on future outbreaks as ecosystems face growing pressure from climate change.

In this episode of BioScience Talks, we spoke with Dr. Treena Burgess of Murdoch University in Western Australia, who also holds an adjunct appointment with the Forestry and Agricultural Biotechnology Institute at the University of Pretoria in South Africa. She describes her recent article in BioScience, written with Michael Wingfield. In it, the authors articulate seven scenarios of pathogen movement and disease epidemics, as well as the biosecurity risks that arise from poorly controlled germplasm movement. The dangers are significant, with economically important eucalypt plantations and native ecosystems both facing significant threats.
