Foliar water uptake (FWU) could be relevant for the plants, allowing them to use alternative water sources and thus prevent dehydration especially during the dry season in arid/semiarid ecosystem characterized by small and erratic water pulses. The main objective of this study was to evaluate the effects of FWU on leaf water status and its contribution to daily transpiration in an arid ecosystem in southern Argentina. Eight dominant species, including shrubs and grasses, with different rooting depth (< 0.5 m,
