Some previously reported heritabilities are significantly lower than the values reported here. There are a number of factors which may account for the discrepancy, relatedness assumptions are a likely candidate. There was no consistency across studies in assumptions regarding relatedness, as they have differing levels of knowledge of their populations and species. A number of the previous studies were multisite studies and may include growth restricted sites, high mortality etc. which likely contribute to the comparatively low values. A single nursery site study gives much more control over environmental variation, and hence higher discernable genetic influences (for the particular environment). \citet{Davies2017} was a single nursery site study, which produced similar values to the ones reported here. Genetic parameters could be expected to reduce when considered over multiple sites with harsher growing conditions. Given the large variation and limited previous studies, significant conclusions with regard to the previously reported genetic correlations and those reported in this study cannot be drawn.  Measurement error reduces calculated heritability as it adds random error to all results, it may have a significant influence on all of the reported traits here, however is likely quite pronounced for strain, as it will be in all studies measuring growth-strain.
Genetic correlations require more data and complex statistical modeling than heritability estimates. As a result fewer have been reported. Relevant genetic correlations in various eucalypt species are reported in Table \ref{221635}.
Investigating multiple populations to gain an understanding of genotype x environment interaction information is common practice among modern tree breeders. Our study dealt with a single site; however, the trial represented multiple provenances, some of which were partially geographically isolated from the remainder of the population. No previous studies have investigated divergent evolution in E. bosistoana. While no clear differences existed between provenances within this experiment, further work is needed to identify where true provenance boundaries lie, as a better understanding of the genetic isolation of various sub populations of E. bosistoana may help explain the comparatively high heritabilities in this study.
