Leonie Valentine

Leonie is a conservation biologist working as a postdoctoral research fellow in the ERIE lab.  A consistent theme of her research is investigating how and why fauna respond to disturbances, understanding the role of fauna in ecosystem function and restoration ecology, and exploring novel resource use by threatened animals.

Leonie has worked in northern and south-western Australia as a conservation researcher and a manager for state government agencies.  Her previous research examined the responses of reptiles, birds and their resources to invasive species, fire and land management strategies.  Leonie’s current research examines the role of digging mammals as ecosystem engineers and how translocations of threatened species may be important for landscape restoration.  Her work is often collaborative with conservation management agencies and she hopes that their joint research will result in greater conservation outcomes.

Originally from northern Queensland, Leonie completed her doctoral research at James Cook University on the impacts of an invasive weed, rubber-vine, and fire management on fauna in tropical savannas. After moving to Western Australia, she worked on biodiversity issues related to the Gnangara Sustainability Strategy for the Department of Environment and Conservation; and as a post-doctoral researcher at Murdoch University for the WA Centre of Excellence for Climate Change, Woodland and Forest Health.  She joined the UWA ERIE team as a postdoctoral researcher in late 2012.   She currently works part-time, living somewhat vicariously through her students, and hopes to stay working with the ERIE team for many years to come.

Teaching and Community Service

Leonie regularly engages with community groups and enjoys sharing research findings to a broad audience. She has provided research and conservation advice on numerous committees, including the Black Cockatoo Project Advisory Group.  In addition, Leonie is an Associate Editor for Austral Ecology, and provides reviews in her professional capacity for a number of journals.

In a professional teaching capacity, Leonie has been a co-supervisor for numerous research students.  She has previously been involved in supervising to completion 4 PhD, 4 Masters and 7 Honours students.  She currently co-supervisors a number of fabulous students (5 PhD and 1 Masters), listed below, and wishes she could do the field work with them all.
