Street Tree Species Trials
Street tree trials have been a fundamental part of TREENET since its inception in 1997.
Knowing how trees grow in the different town and city environments across Australia is essential to sustaining our urban forests, so trial plantings are an important part of Treenet’s research. Treenet collaborates with communities, governments, schools, researchers and others to plant and monitor trees across Australia. Results presented at our symposia are available in the Australian Urban Forest Literature Database and links to some selected papers and videos are provided below.
Examples of some of the many tree species growing across Australia can also be seen in Treenet’s Urban Tree Trials Database. You can use this free database to access, share or contribute to tree species or trials information.
The database is a work in progress with information being added to include past, current and new trials, as well as showing how trees have matured in different regions. To continue to build this database we encourage anyone working on tree trials in their region to upload their information. Adding information requires a login, which you can request here.
Further information about street tree performance and establishing tree species trials is available in these Treenet resources:
- Street tree species trials for the 2020’s – Lyndal Plant and Tim Johnson, 2021
- Street Tree Trials – Ruby Wilson, 2022
Additional information to assist with establishing tree trials can be found in the Climate-ready street tree trial guide, and the Which Plant Where database provides broad information for plant and tree selection.
Further resources and publications from Treenet’s Australian Urban Forest Literature Database are listed below.
