Table 3 Change in mean (± standard error, minimum–maximum) growth dominance GD in the different CTRN treatments (n = 6 per treatment) 1 to 3 and 8 to 10 after thinning. GD values greater than 0 signal growth dominance of larger trees (i.e., contribution to total stand growth by larger trees is greater than their contribution to total stand basal area), whereas negative GD values signal growth dominance of smaller trees and GD values of 0 indicate no growth dominance, i.e., proportional contributions of each tree are the same for basal area (size) as for basal area increment (growth)
