ILWS PhD Graduate
The detectability of cryptic birds (Lewin's rail and other rail species) to assist with conservation/management options.
Liz commenced her PhD in June 2015 as a DE student from Tasmania. She was supervised by Professor David Watson and co-supervised by Professor John Woinarski from Charles Darwin University.
Her doctoral research investigated detection methods for secretive marsh (wetland) birds, critically evaluating acoustic-based, camera-based, and conventional survey-based methods. Liz applyed these monitoring techniques in multiple locations; Tasmania and off-shore islands, and, coastal and inland marsh systems in the USA to enable cross system comparisons.
For many marsh obligate species, qualitative and quantitative data are minimal or non-existent, her work highlighting the need for practical methods for data collection which are repeatable, accurate and cost effective.
Liz currently works part-time for Parks and Wildlife Tasmania, and has worked on many different wetland bird and shorebird species. She is also very active in environmental education and interpretation in schools and community groups.
Rails and other wetland obligate species are generally cryptic ground dwelling birds that are particularly vulnerable to population declines without notice due to the limitations of current survey methodologies. Liz's research is contributing to the ARC Discovery Project Bio-Acoustic Observatory: Engaging Birdwatchers to Monitor Biodiversity by Collaboratively Collecting and Analysing Big Audio Data.
Liz has worked with Clare Thomson to create a video to demonstrate the outcomes and workings of her collaboration with QUT in relation to the article published "Long-duration false-colour spectrograms for detecting species in large audio data-sets."
Membership of Advisory Boards
Liz has been appointed a member of the Federal Government Threatened species Cocos Buff-banded Rail Advisory Panel.
