To Togari field site, SR Salmon River field site.
Correlations for DBH were presented separately for Togari and Salomon River field sites due to genotype by environment interaction at the sub-race level.
NA = no additive genetic variance
significant at P<0.05; **significant at P<0.01; *** significant at P<0.001.
∧ = significance could not be determined using a likelihood ratio test.
Correlations with browse damage are using data from Togari common garden trail only
