However, a strong δ2H offset between soil and xylem water isotopes observed in peak summer could suggest that both tree types were not physiologically active under extreme drought conditions. Alternative processes causing deuterium fractionation, however, could not be ruled out. Tree height and recent (last 15-25 years) growth rates in all species studied were lower in D than in ND trees by 22% and 44%, respectively. Lastly, there was not a consistent pattern on NSC sapwood concentration, showing that in Q. pubescens was higher
