Short summary
Complex plant–soil interactions in the hydrological cycle of a Mediterranean cork oak ecosystem are investigated with stable water isotopes. Trees largely foster infiltration due to altered microclimatic conditions below crowns but compete with understorey plants for the same water source in deeper soil layers. The presence of understorey plants does not alter water losses compared to bare soil, but water utilization for carbon sequestration and nitrogen fixation is largely increased.
