First it was the hopeful-but-questionable ‘One Trillion Trees’ initiative, announced at the World Economic Forum in Davos, with supporters as diverse as Jane Goodall and Donald Trump. At the same time, large areas of Australia were on fire – in total, estimates are that we lost 20% of our forest cover in the climate-change-driven ‘Black Summer’ fires that only recently subsided.
Recent collaborative research from our lab brings the focus back onto our urban trees. While a few billion hectares of new forest may slightly slow climate change at a macro level, we also need immediate solutions in our cities. In the places that most of us live and work, trees have an important role to play in helping us adapt to the warming (and flooding) that’s already locked in.
The thing is, we’re losing quite a lot of trees to construction, and even well-resourced teams are working hard to keep ahead of losses. In a new paper, Thami Croeser (ICON Science) led a team which found that The City of Melbourne has lost over 10,000 street trees in the decade of 2008-2017; 2000 of these were within 10m of a major development.
The good news is most of these were small trees, possibly reflecting the city’s tough controls on tree removal. The original research was published in Sustainable Cities and Society; we also had media pickup from The Conversation and Domain, where we talk a bit about how improvements in tree planting, tree protection and building greening can all play a role in keeping our cities green as they grow.

The American conservationist Aldo Leopold wrote about the importance of practicing a ‘land ethic’, adopting personal responsibility for the health of the land – the soils, waters, plants and animals of a place – for the good of the community. Private land stewardship, caring for native flora and fauna on one’s property, has long been promoted in rural settings as a valuable contribution to conservation. By contrast in cities, conservation activities and research have focused on public land. Indeed, it has been suggested that urban landowners are unlikely to demonstrate the levels of land stewardship found rurally for lack of opportunity or the stronger place meanings and sense of place found in the country.
I interviewed 16 members of a municipal wildlife gardening program (Knox Gardens for Wildlife) in Melbourne Australia to understand how participation affected their reported gardening purpose and practice, and attachments to place and nature. Using inductive analysis and a definition of land stewardship derived from Aldo Leopold that includes purposes as well as activities, I developed a model for the development of urban land stewardship (below). It includes an initiation phase that introduces participants to stewardship and their potential to contribute, followed by a development phase where connections to place deepen; stewardship knowledge, competences and activities strengthen; and commitment to stewardship increases.
A model for the development of urban private land stewardship
Results show that urban wildlife gardening programs can foster residential land stewardship through learning by doing. Visible community involvement and endorsement of one’s contribution are key, and connections to nature, place and community occur as part of the process.
