Using botanic gardens and arboreta to help identify urban trees for the future

Diversification of urban forests is essential to enhance their resilience to future biotic
threats as well as those posed by a changing climate. Arboreta and botanic gardens
host a wide range of plant material that can be evaluated to...

Assessing the vulnerability of Australia’s urban forests to climate extremes

Urban forests are recognized for the multiple benefits they provide to city‐dwellers.
However, climate change will affect tree species survival and persistence in urban
ecosystems. Tree failures will cause economic losses and jeopardize...
