"As Australian cities heat up and dry out, street trees are emerging as
frontline defenders of urban liveability.
Street trees make city life more bearable during heatwaves. They also improve
human health and wellbeing, filter pollutants and support biodiversity.
But as climate change intensifies droughts and dials up more extreme heat, can
urban forests survive in a hotter, drier future?
To find out, we studied how ten of Australia’s most common non-native street
trees grow and tolerate drought across seven cities. The familiar species we
chose are the well-loved jacaranda and widely planted London plane tree as well
as box elder, European nettle tree, honey locust, sweetgum, southern magnolia,
callery pear, black locust and Chinese elm.
Unexpectedly, our new research shows several species tolerate drought better
than predicted, including jacaranda and London plane. Some even put on growth
spurts during droughts of unprecedented duration and heat. But others showed
greater sensitivity than we had anticipated, including honey locust and black
locust.
As cities plan for a hotter future, our research will help urban planners
choose the toughest, most resilient street trees."
