Quantifying inter-species differences in root hydraulic properties

Project Overview
Root systems act as the gateway for water and nutrients to pass from the soil into the plant vascular system. Though the importance of below-ground water uptake processes has long been recognized, treatment of these processes in land surface models has been largely limited to empirical formulations based on biomass profiles. Recent model advances have improved the three-dimensional representation of root systems in hydrological models, but the parameterization of root hydraulic properties remains a source of significant uncertainty. This project focuses on measuring root hydraulic conductivity for dominant tree species and other relevant ecophysiological properties. These measurements will support modeling efforts and improve projections of forest hydrology under changing climate.
