Using the heat field deformation technique for measuring sap flow in several forest species and sites across Europe, we were able to provide evidence on different types of hydraulic redistribution (HR): vertical hydraulic redistribution, horizontal hydraulic redistribution, foliar uptake and tissue dehydration. Results from direct sap flow measurements indicated the vectoral and widespread nature of HR, a phenomenon of paramount importance for overall physiology and ecohydrology.
