How plants and trees talk to each other and why we should care

The last decade has seen significant scientific discoveries on how forests sense, respond and communicate – yet we haven’t paused to understand what these discoveries mean for us and trees.

Inspired by a new exhibition by acclaimed artist Janet Laurence: After Nature, the University of Sydney is leading a series of public talks called Talking Trees. The talks bring together artists, researchers and advocates to exchange and discover new ideas around one of the most vital elements of the natural world: trees.

“We wanted to combine science and art and public discussion to really wake people up to the importance of plants,” said Professor Margaret Barbour, a plant scientist in the School of Life and Environmental Sciences.

“Janet Laurence has done more to highlight the reality of the environmental catastrophe we face than almost any other living Australian,” said Professor Marc Stears, Director of the Sydney Policy Lab. “The Sydney Policy Lab is absolutely thrilled to be working with her and with the MCA over the next few weeks in bringing some of the country’s best scientists, artists, thinkers and activists together to see how we can escape that environmental catastrophe and collectively build a fairer, richer and more sustainable future.”

The Talking Trees series is held at the Museum of Contemporary Art. The program is a collaboration between Dr Dalia Nassar (University of Sydney), Professor Margaret Barbour (University of Sydney), Sydney Policy Lab, the MCA and artist Janet Laurence.

“All of the big moments of political change have been driven by movements in art, from the campaign for the vote to women to the civil rights campaigns of the late 20th century,” said Professor Stears. “We’re now witnessing the birth of a major artistic movement demanding change to protect our environment. Janet Laurence’s MCA show is a big part of that movement.”

“We don’t often take notice of the plants around us,” said Professor Barbour. “Janet is waking us up through her artwork, and we want to wake people up to the science by bringing together a range of speakers from arts and science to broaden our understanding of environmental issues.”

Talking Trees, series of talks

The Language of Trees

March 6

Can trees talk to each other? How do we talk about trees? How powerful are words when it comes to caring about the environment? Hear from linguist Nick Enfield, evolutionary ecologist Monica Gagliano, sound artists Liquid Architecture, and Indigenous language expert Jaky Troy, on the power of words we use to speak about trees.

Trees and Democracy

April 20

Do trees build a stronger sense of belonging and wellbeing? Living in a green neighbourhood is good for our health, but who has access to these neighbourhoods? And as green spaces are under attack, what happens to our democracy?

Confirmed speakers include Councillor Jess Miller, artist Raquel Ormella and cognitive neuroscientist David Strayer from the University of Utah.

Trees and time

May 1

Could the effects of climate change be etched in tree trunks?

A scientist, civil society leader and an Indigenous leader will unpack the lessons we learn from trees about the human impact on nature. Trees contain their own histories, capturing timescales far beyond the human lifespan. Speakers to be confirmed.

Trees, art and social change

June 2

How has art played a role in environmental movements, and what role could it play in stirring the pot today? Confirmed speakers include former leader of the Australian Greens, Bob Brown, artist Janet Laurence and Dr Amanda Tattersall of the Sydney Policy Lab.
