Risks to Australia's urban forest from climate change and urban heat

Australian cities contain millions of trees that provide amenity, important ecosystem services such as cooling and slowing stormwater, and provide habitat for birds and animals. There is growing recognition that increasing temperatures due to urban heat and climate change are a threat to some tree species in our cities. This study analyses the risk of temperature increases to 1.9 million trees in 29 LGAs across Australia, from Launceston to Darwin, and Brisbane to Perth. Every tree was analysed to see how close it was to known temperature limits in current climates, an emissions limited climate change scenario in 2040 assuming emissions stabilisation, and a business as usual emissions scenario in 2070.
