Dendro Down Under: Expanding Tree-Ring Research in Australia

The Laboratory of Tree-Ring Research (LTRR) at the University of Arizona is pleased to announce that Dr. Heather Haines will be giving this week’s talk mentioned above in Bannister 110 and via zoom.


Dr Heather Haines has been at the forefront of Australian tree-ring research since beginning her PhD at Griffith University (Brisbane, Australia) in 2013. She specializes in analysis of non-traditional tree species for both palaeoclimatological and ecological study with a focus on combining ring-width analysis with isotopic measurements and densitometry. In this seminar Heather will discuss her adventures in undertaking dendrochronology in Australia with a focus on three area of dendrochronological studies.

The first area will discuss the potential uses of Australian trees in the development of long-term tree-ring climate reconstructions. Specifically, she will cover at the use of Araucariaceae species which have led to the construction of the longest high-resolution drought record for Subtropical Australia. She will also discuss combining ring-width and isotopic measurements to expand on the environmental data which can be developed at a single site – specifically in proxy poor regions like Queensland, Australia.

The second area of study will present some recent ecological research focusing on both threatened and critically important Australian species to understand their response to changing climate and fire patterns as well as the importance of preserving these species under changing conditions.

Finally, Heather will discuss work she has undertaken in her previous position at the Chronos 14Carbon-Cycle facility at the University of New South Wales (UNSW) in Sydney where she has been leading research to identify Solar Energetic Particle (SEP) events in the Southern Hemisphere based on sub-annual scale radiocarbon analysis.
