Title: Plant moisture stress patterns in planted Douglas-fir: a preliminary study of the effects of crown and aspect

Author: Lindquist, James L.;

Date: 1977

Source: Res. Note PSW-RN-188. Berkeley, CA: U.S. Department of Agriculture, Forest Service, Pacific Southwest Forest and Range Experiment Station. 5 p

Publication Series: Research Note (RN)

Description: Plant 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.

Keywords: Douglas-fir, moisture stress, aspect (plant cover), crown cover, canopy, regeneration
