DescriptionPlant moisture stress (PMS) regimes over the summer were determined in planted Douglas-fir seedlings in clearcut and partial-cut blocks on the south slope clearcut, PMS reaches levels that after June could seriously reduce seedling growth. The PMS of the clearcut plots exceed 15 atmospheres at midmorning in June, but partial-cut plots do not exceed this level until September. The greater PMS of the south clearcut plot has not retarded height growth of the Douglas-fir. This is the only plot, however, on which regeneration stocking is not adequate.
