Online abuse and bearing witness to the destruction of what many of us know (and love) intimately can take a heavy toll on scientists and environmental advocates. But the choices we make now will determine the future we inherit. Far from feeling that all is lost, Euan Ritchie urges all to speak and act for the voiceless, to care for and defend what you love.

Working adaptively with fire as a tool for ecological health can help us to prevent the extinction of flora species across Victoria’s ecosystems. Ella Plumanns Pouton (University of Melbourne/Deakin University) works to understand how fire regimes support different plants across their whole life cycle, providing a vital scientific foundation for fire management practices that respond to the unfolding global biodiversity crisis.

Prescribed burns are said to mimic First Peoples’ cultural burning practices, but Dr Philip Zylstra argues the use of fire in healing and managing Country is far more complex. Australia is wet enough for things to grow, and dry enough for them to burn. Animals and plants have adapted. And over millennia, First Peoples developed cooperative fire regimes.

Fire patterns are linked to climate conditions, and have been undergoing changes in tandem with anthropogenic climate change. We must understand these changes to more effectively forecast and manage fires for both human safety and the preservation of biodiversity. Kate Bongiovanni explores Dr Luke Kelly’s work on “pyrodiversity.”

Despite the changes that occurred after European settlement, Melbourne’s urban waterways still contain remnant ecosystems, which faintly echo the diversity they once displayed. In addition to their contribution to the city’s environmental values, urban waterways also provide important social, economic, and aesthetic benefits.
