Short summary
Water-use studies comparing pine and Eucalyptus are limited. This study used internationally recognized methods to measure water use by Eucalyptus and pine over two seasons. Results showed that, over one season, pine used more water than Eucalyptus, which was contrary to previous long-term studies. However, the Eucalyptus site was found to be water stressed. This study concluded that the observed water stress and reduced transpiration rates must be included in hydrological models.
