Trees Growth; Soil moisture; Lodgepole pine. during the second period, a similar regression accounted for 88. 0 percent of all variation and was significant far beydund the 1-percent level (fig. 13). The stronger relationship during the second period is partly the result of a greater range of densities. The lowest level was substan- ially lower during the second period and therefore produced much less wood. Consequently, the range in volume increment from high to low was much greater and contrasted more strongly with the random var- iabilit

The stronger relationship during the second period is partly the result of a greater range of densities. The lowest level was substan- ially lower during the second period and therefore produced much less wood. Consequently, the range in volume increment from high to low was much greater and contrasted more strongly with the random var- iability among plots treated alike. There was also a tendency for plots treated alike to produce more nearly alike during the second period. Regressions of volume increment on logarithm of basal area (fig. 14) and on logarithm of crown competition factor (CCF) (fig. 15) are very similar to the bole area regression. The bole area regression accounted for slightly more variation with the Twin Lakes data. However, the range was only from a low of 85. 5 percent with the CCF regression to a high of 88. 0 percent with the bole area 18.
