Acustic Velocity & 0.60-1.0 \\   Stiffness & 0.48-1.0 \\   \end{tabular}   \caption{Narrow sense heritability of measured wood properties, calculated as per equation --.} \ref{gse}.}  \end{table}  Wood processors pay premiums for timber stable and stiff --ref--, while forest growers prefer to have fast growing trees as to shorten rotation lengths increasing profitability --ref--. The preferences are not always aligned, particularly within wood properties. Stiffness, used for grading logs, is positively correlated with growth-strain with a Person correlation coefficient of 0.61, a substantial unfavourable correlation requiring a trade off between the two. While zero growth-strain is desirable to be economically viable to process, some unknown maximum value below which little economic loss is experienced exists. Stiffness is already used for log grades, structural timber in New Zealand requires a minimum of --val, ref-- while in Europe structural timber requires --val ref--. To met these stiffness grades at age two some compromise with the level of growth-strain is needed --describe more--. Volumetric shrinkage is moderately negatively correlated with stiffness and strain --same as other literature?-- Growth and density show only small correlations with all wood properties.
