Just Ecology

After more than 20 years working in ecology, I have come to realise that beekeepers, or apiarists, often possess a more detailed understanding of eucalypt flowering than anyone else. Their knowledge extends far beyond when particular trees flower, encompassing eucalypt ecology, geographic variation and the relationships between species, climate and soils.

Few people embody this knowledge more remarkably than Stuart Fraser. Now in his eighties, Stuart is a lifelong beekeeper who has spent much of his life travelling through forests with bees and closely observing the flowering cycles of eucalypts. He is part of a family beekeeping lineage stretching back more than a century, through which an extraordinary body of ecological knowledge has been observed, tested and passed from one generation to the next. As Stuart once said to me, when your livelihood depends on something, you tend to pay attention.

I wanted to introduce Stuart to Vicky Shukuroglou, author of Ace Guide to Eucalypts Melbourne, whom I interviewed for Episode 19, and this episode brings together a conversation between the three of us.

We explore the immense honey-producing landscapes known by earlier generations, including forests where nectar reportedly fell from the flowers and gathered on the ground. Stuart shares his remarkable knowledge of the flowering cycles and geographic variation of Ironbark, Grey Box, Yellow Box, River Red Gum and the mallees, and explains how beekeepers read budding patterns, rainfall, soils and even the overall appearance of a tree to anticipate whether it will yield nectar. We also reflect on land clearing, declining insects, climate change, fire, Varroa mite and the irreplaceable value of ecological knowledge built through generations of close observation.

Five key lessons from the interview:

Eucalypt flowering follows complex cycles. Different species set buds and flower over periods ranging from months to several years, influenced by the timing of rainfall, heat and seasonal growth.

Flowers do not necessarily mean nectar. A tree can be covered in blossom yet produce little nectar; experienced beekeepers learn to recognise whether a flowering event will actually yield.

The same eucalypt species varies enormously across the landscape. Yellow Box, Grey Box and River Red Gum can differ in appearance, flowering time and nectar production according to location, soils and local conditions.

Historic nectar flows were vastly greater than today. Stuart described forests where nectar reportedly dripped from flowers and collected on the ground, supporting immense numbers of insects, birds and commercial beehives.

Generational observation creates exceptional ecological knowledge. Stuart’s understanding was built through decades of experience and knowledge passed down by earlier beekeepers whose livelihoods depended on closely reading trees, weather and landscapes.

What does it really mean to listen? For Andrew Skeoch, listening is far more than hearing sounds or identifying bird calls. It is the foundation of relationship—a practice that invites us to pay attention, to be influenced and ultimately to learn from the living world.

Drawing on more than three decades of recording wild soundscapes, Andrew reflects on what birds, ecosystems and the remarkable lives of other species can teach us. Together, we explore why nature is better understood as a web of relationships than a collection of separate parts, and ask what might become possible if we approached the world with greater curiosity, humility and attention.

Andrew Skeoch is a naturalist, environmental thinker, educator and one of Australia's best-known sound recordists. For more than three decades, he has recorded wild soundscapes across Australia and around the world through Listening Earth. He is the author of Deep Listening to Nature, which explores how listening can deepen our understanding of the natural world and our relationship with it.

How well do we really know the trees around us?

In this episode I sit down with multidisciplinary artist, ecologist and author Vicky Shukuroglou to talk about eucalypts — those familiar yet endlessly fascinating trees that shape much of the Australian landscape. Vicky shares the story behind her new field guide - Ace Guide to Eucalypts Melbourne - exploring what inspired the project and the immense effort involved in bringing it to life. What begins as a conversation about the guide soon becomes an exploration of observation itself: how we learn to recognise trees, what classification can and cannot tell us, and how deeper attention reveals an extraordinary world of variation, relationships and stories.

Together we discuss Melbourne's diverse landscapes, from dry western plains and Ironbark forests to towering Mountain Ash country, exploring the ecology, evolution and cultural significance of these remarkable trees. Along the way we talk about conservation, habitat, climate change, the value of local knowledge and the importance of fostering a genuine relationship with the living world.

Through art, writing, community learning and ecological practice, Vicky encourages people to develop more attentive and meaningful relationships with place. Vicky is co-author and photographer of the book Loving Country and has spent many years exploring the connections between creativity, ecology, culture and care for Country.

Botanic gardens are sometimes viewed as rather static places — collections of plants, all neatly labelled. But as today's guest explains, they are so much more than that. In this episode I sit down with Professor Tim Entwistle, botanist, author and former director of three major botanic gardens including Melbourne, Sydney and Kew Gardens in London.

We explore the origins of botanic gardens, from the medicinal gardens of Renaissance Italy through to the great botanic gardens of today. Tim describes how modern gardens combine science, education, culture and recreation, becoming places where people can learn, celebrate and connect with the living world. We discuss some of Australia's most significant gardens, including Melbourne's Royal Botanic Gardens and the Australian Garden at Cranbourne, as well as the important role played by regional botanic gardens across Victoria and beyond.

Along the way we talk about plant collections, herbaria, seasonal calendars, First Nations knowledge, climate change adaptation and the future of urban green spaces. Tim also shares the story of a beloved 150-year-old oak tree in Melbourne's Royal Botanic Gardens and how its legacy inspired his latest book.

Tim Entwistle is a botanist, writer and public communicator who has spent decades helping people better understand plants and their place in our lives. His books include Evergreen, The Skeptical Botanist and the forthcoming Three Worlds Oak.

Mosses, along with their cousins the liverworts and hornworts, make up the world of the bryophytes, fascinating plants that have been on this planet for well over 400 million years. I sat down with Dr Cassia Read to explore these amazing plants, where we talk about where to find them, how different species are identified, why classification is important and the critical roles of bryophytes in our ecosystems. Cassia spent years studying and researching bryophytes in the drier semi-arid parts of south-eastern Australia, a place where many don’t expect to find these plants, and we learn about how mosses survive in such dry conditions. We also discuss the role of mosses in ecological restoration, and the emerging possibilities of including bryophytes in the healing of degraded lands.

Cassia is an ecologist, educator and garden designer whose work centres on creating landscapes that support both human wellbeing and biodiversity conservation in a changing climate. Her interests span landscape ecology, planting design, climate adaptation, urban greening, wildlife gardening and community engagement, and she has conducted fieldwork across a wide range of ecosystems throughout southern Australia. She is a co-founder of the Castlemaine Institute, an organisation focused on strengthening regional communities through research, education and collaborative responses to social and environmental challenges.
