Berdanier in Tree Physiol: Predictive models for sap flux
Predicting whole-tree water use requires models that accommodate the variation in sap flux between wood types and by depth into the tree. We develop a method for scaling-up flux observations. As an illustrative example, we predict sap flux for a forest in North Carolina, quantifying changes in water use with tree species and size. We include computer software for generating whole-tree flow estimates with other observations in Excel® and the R programming language.
