Abstract
This paper arises from a field study of blackbox trees (E. largiflorens) in a railway corridor in South-Eastern Australia. Sap flux gauges embedded in tree trunks were used to measure transpiration rates every 30 minutes and an on-site weather station recorded data for the determination of reference evapotranspiration every 15 minutes. Soil suction samtyles were taken to a depth of approximately four metres, on two occasions within the year of monitoring. TotalĀ· suctions were measured and solute suctions were estimated from electrical conducti~ty testing. Trench excavations were made to record root extent of one tree specimen. The relationship between daily tree water use, reference evapotranspiration and soil moisture state are explored
