On 24 other nights, lower rates were observed and transpiration was tightly correlated with vapor pressure deficit and nighttime wind speed. Imported to the United States around 1860, the trees are native to Australia and up until 1990 were relatively pest and disease free. E. grandis is found on coastal areas and sub-coastal ranges from the vicinity of Newcastle in New South Wales northwards to Bundaberg in central Queensland with disjunct populations further north near Mackay, Townsville and Daintree in northern Queensland, mainly on flat land and lower slopes.
