  abstract = {{K}arst environments are unusual because their dry, stony and shallow soils seem to be unfavorable to vegetation, and yet they are often covered with forests. {H}ow can trees survive in these environments? {W}here do they find the water that allows them to survive? {T}his study uses midday and predawn water potentials and xylem water isotopes of branches to assess tree water status and the origin of transpired water. {M}onitoring was conducted during the summers of 2014 and 2015 in two dissimilar plots of {M}editerranean forest located in karst environments. {T}he results show that the three monitored tree species ({A}bies alba {M}ill, {F}agus sylvatica {L}, and {Q}uercus ilex {L}.) use deep water resources present in the karst vadose zone (unsaturated zone) more intensively during drier years. {Q}uercus ilex, a species well- adapted to water stress, which grows at the drier site, uses the deep water resource very early in the summer season. {C}onversely, the two other species exploit the deep water resource only during severe drought. {T}hese results open up new perspectives to a better understanding of ecohydrological equilibrium and to improved water balance modeling in karst forest settings.},
