Pearson’s correlation coefficient was >0.5 between box
dimension and crown projection area and crown volume with moderate no
thinning (Table 4). However, the correlation was significant
(p<0.001) between box dimension and all crow attributes with
all thinning treatments. However, the correlation between box dimension
and stem attributes, benefit-to-cost ratio, growth, as well as light
availability was mostly <0.5 indicating a weak relationship
between them. Nevertheless, the Person’s correlation coefficients were
found significant for stem attributes in moderate thinning and for
growth attributes in control plots.

stem and crown attributes, benefit-to-cost ratio, growth attributes, and
light availability grouped by thinning treatment. Correlation
coefficients >0.50 are bolded and * denotes statistical
significance (p<0.001).
