For Sedran-Price, a researcher at the University of Sydney, these seeds are more than biological data points. They represent a continuity of life that stretches back through generations of Aboriginal and Torres Strait Islander people. Her work, alongside fellow scientist Jacob Birch from the University of Queensland, focuses on creating community-led seed banks. These are not merely cold storage facilities, but living libraries where the knowledge of how to harvest, treat, and grow bush foods is preserved alongside the genetic material itself.
The challenge is immense. In the Australian bush, many seeds possess a stubborn, protective coat that requires the intense heat of a wildfire or the chemical signature of smoke to trigger germination. Birch and Sedran-Price work closely with local rangers to identify these species on Country. They use hand-harvesting methods to ensure the root systems of the parent plants remain undisturbed, a gesture of respect for the land that provides the bounty.
In Canberra, the Australian Academy of Science awarded the pair the 2026 Aboriginal and Torres Strait Islander Scientist Award, providing support for research that sits at the intersection of physical science and ancient practice. The recognition highlights a shift in how the scientific community views climate adaptation—not just as a matter of engineering, but as a recovery of lost or overlooked wisdom. In the hands of these scientists, the tjiwa, or traditional grinding stone, becomes a bridge to a future where native grains like Mitchell grass provide food security in an increasingly arid landscape.
Once collected, the seeds are brought to centralized facilities like the Australian PlantBank. Here, they undergo a process of desiccation and freezing, a technical slumber that can last for centuries. It is a quiet, persistent labor. By protecting these species, Sedran-Price and Birch are ensuring that when the next generation reaches out to touch the rough, sun-warmed husk of a native grain, the plant will still be there to meet them.
