Results and Discussion

While the study was larger than preceding attempts, the sample number was still small when considering heritability calculations. The paucity of data resulted in wide 95% credible intervals (Table \ref{559243}), which require more samples to tighten. The heritability indicates that growth strain can be influenced by breeding, and are in line with the 0.32 reported by \cite{Murphy2005}, but are significantly higher than the 0.02 value reported by \cite{Naranjo2012}. Density, diameter at age two (growth), volumetric shrinkage, acoustic velocity and stiffness all have significantly large heritability, suggesting that breeding for these traits is achievable. The heritabilities are similar to those reported for other eucalypt species \cite{Hung_2014,Hein2012,Blackburn2014,Hamilton2008}.
