Associate Professor Rachael Gallagher

I’m a plant ecologist and conservation scientist passionate about protecting, restoring and understanding global plant diversity.

I grew up roaming for hours along the ridgelines of our local patch of bushland on the Central Coast of New South Wales. Following my undergraduate degree in ecology, I joined the New South Wales Herbarium to digitise specimens and was instantly hooked on the possibilities of working with natural history collections in ecological research. Processing specimens, I gained a keen eye for detail about the early Australian botanists and an understanding of the taxonomic breadth in the Australian flora.

I embarked on a PhD at Macquarie University on the functional ecology of climbing plants which exposed me to the world of plant trait research. This built the foundation of my research interest into the many ways traits can be embedded into conservation science. I remain fascinated by this question and develop and apply trait-based approaches to understanding how plants will fare in a hotter, drier and more fire-prone world.

I was supported post-PhD by two fellowships which took me abroad (mainly southwestern USA) and allowed me to dip in and out of full-time academic work while parenting. After becoming a faculty member at Macquarie following my DECRA, I joined HIE in 2021. I’m increasingly interested in how we can achieve better outcomes in ecological restoration, and this is becoming the focus of large-scale experiments being set up on campus at HIE.

Since 2016, I’ve been involved in the legislative protection of Australia’s plants as a member of Threatened Species Scientific Committees for the state of New South Wales (2016-2021; Deputy Chair) and the Commonwealth of Australia (current). I see the value in using my scientific knowledge to work closely with decision makers, and sometimes be one myself.
