Dr Natalie Briscoe’s fascination with wildlife goes right back to her early childhood. Living in the foothills of the Dandenong Ranges
outside of Melbourne, she was surrounded by bush and inspired by how animals were adapted to different environments, often coping with adverse conditions.
And this fascination led to a career in analysing what it takes for a species to persist in a changing climate, and how this understanding helps identify
what they need as refuge.
I was very fortunate in my early life. I lived in a wonderful bush setting and had a wonderful biology teacher in high school. She channelled my natural curiosity about wildlife into a more scientific way of thinking. I was particularly interested by how different animals managed to make a living in so many different ways, across such diverse environments.
At university, I pursued these interests with a major in zoology, alongside politics. This strange sounding combination proved valuable. Not only did I learn about the ecology of different species’ and systems – but I also gained insight into how different societies function, and the drivers of many of the stressors on wildlife. I was particularly struck by the challenge of conserving biodiversity in the face of climate change, in highly modified landscapes. I began to appreciate that to manage species we need to understand their resource needs and what limits their survival.
My research has combined my curiosity for understanding how animals ‘make a living’ in their environment, with the desire to apply this knowledge to better protect them. I spent my PhD researching how koalas will be affected by climate change. I collected data on their physical traits and physiology, as well as how they behave in different weather. I then used this information to build a model that predicts how much energy and water koalas need to live in a particular place, based on the climate at that location. Using this model, we were able to predict which areas are likely to remain suitable for the koalas in the future – thereby identifying priorities for protection.
Along the way, I also learnt a lot about how koalas cope with the diverse range of environments they live in. In south-eastern Australia, for example, koalas cool down by hugging cool tree trunks during hot weather. It turns out that this behaviour is really effective at helping them cope with temperature extremes, when water is scarce. As a scientist, I love uncovering new information like this. But it can also help us protect koala populations, highlighting the importance of trees that provide cool tree trunks and deep shade, alongside trees they feed on.
One of the best things about my job is that I work with a broad range of people who have incredible knowledge about the ecology of different species and systems, and a passion for making a difference. As part of my current work for the TSR Hub identifying and managing refuges from threats, I’m working with land managers, field ecologists, hydrologists, as well as experts in modelling and animal physiology. Together we’re trying to identify strategies to reduce the impact of disease on threatened frogs, as well as understand what feral predators need to survive in different environments, so that we can better target management.

How do animals like koalas cope with climate change in (already) heavily modified forests and woodlands? What environmental elements would provide them refuge in the future when extreme weather conditions are forecast to be more frequent? Photo: Greta Frankham
Karajarri Rangers are leading a Threatened Species Recovery Hub research project to investigate how different fire management approaches affect biodiversity. The first field trip took place in April this year, when a team of 16 rangers, support staff and scientists journeyed to the Edgar Ranges for eight days of wildlife monitoring. Hub researcher Sarah Legge worked with the rangers to compile this report from the field.
Cissy Gore-Birch is a member of the Threatened Species Recovery Hub’s steering committee and the Chair of its Indigenous Reference Group. The Indigenous Reference Group was established to assist hub leaders and project teams to strengthen the engagement and participation of Indigenous people in the hub’s activities and research projects. Cissy recently attended the Species of the Desert Festival on the Paruku Indigenous Protected Area, where she spoke about both threatened and culturally important species, and increasing the voice of Indigenous people in environmental policies and research.
Dr Sally Box, the Australian Government’s Threatened Species Commissioner, talks about the importance of working with Indigenous groups to conserve Australia’s threatened species.
Researchers from the Threatened Species Recovery Hub are calling on citizen scientists to help them learn more about Australia’s possums and gliders by recording sightings in a new, free app. Dr Rochelle Steven from the University of Queensland is passionate about Australia’s possums and gliders and believes people in the community can do a lot to help support conservation, especially in urban areas.
There are 27 different types of possums and gliders in Australia. They have a huge variety of sizes, shapes and appearances. We’ve compiled a profile on every species here. One quarter of our possums and gliders are listed as threatened under Australian environmental law. Help their conservation, be a citizen scientist: you can record sightings of possums from your local areas in the free 'CAUL Urban Wildlife App'.
