. Growth and soil moisture in thinned lodgepole pine. Trees Growth; Soil moisture; Lodgepole pine. t/i LU g 5 o oc C9 £ LU s < ° . BOLE AREA (SQUARE FEET PER ACRE) MAY JUNE JULY AUG. SEPT. Figure progress of diameter growth during 1969 by stand density. densities; however, it could easily be accounted for by variation among plots treated alike. Height growth during the second 5-year period was very similar to that during the first. Height increase of the 100 largest trees per acre was only slightly better than that for all trees. Height increase of these larger trees averaged 6. 4 feet and ranged from an average of 5. 4 feet on one plot to 8. 0 on another. Basal Area Basal area increment averaged 4. 2 square feet per acre annually during 1960-64 but fell to square feet during 1 965-69.— I The drop represents mainly the normal decrease with increasing age, but lower densities at most levels during the second period were almost certainly partly responsible (fig. 10). 1'These figures are for the original 10 plots only during both periods. 1 5.
