Mature beech and spruce trees were drought stressed for 5 consecutive years in the KROOF experiment. No signs of Carbon Starvation were found under the drought treatment, but overall the carbon pool sizes were reduced by about 40% in both species and carbon transport velocity in the phloem was reduced by about 50 %. Upon watering both species recovered their water household related physiology (water potential, osmotic acclimations and sap flow density) within the next vegetation period at the latest, displaying a high resilience potential, with beech recovering faster than spruce.
