\section{Method}  \textit{Eucalyptus bosistoana} was planted as seedlings into 100 (check this) L planting bags at an irrigated nursery site in Harewood, Christchurch, New Zealand. Two separate plantings occurred in 2010, and in 2012 (months?) The 2010 plant genetics originated from south east Australia and were harvested and coppiced in 2012 and harvested again in December 2014. The 2012 planting genetics originated from higher altitudes in New South Wales and was harvested in 2013 (at one year old, data not incorporated due to the magnitude of errors induced by small melformed malformed  stems) and again October 2015 (at age two). When harvested each sample was processed for growth strain, volumetric shrinkage (displacment (displacement  method, before and after drying), stem diameter (digital calipers), callipers),  basic density (mass and displacment displacement  method) and dry acoustic velocity (resonance from WoodSpec --ref--). Growth strain was measured using a modified version of --kens refs-- method. The newly devaloped "rapid splitting test" substantually substantially  reduces measurment measurement  time enabling larger numbers of samples to be processed. The new method involves stripping the bark and measuring the underbark under-bark  big end diameter of a clear section of the stem, giving an over estimate of the average diameter used by --ref--. The slit length is determened determined  by the length of clear wood and diameter of the sample, measured, recored record  and cut, the error induced has been examined by --ref--. The small end of the sample is left intact with the large end free to distort, (removing the need to clamp the two halves togeather) the opening is measured and recored. recorded.  The calculation of strain is uncheanged unchanged  (with the exeption exception  that average radious radius  is now big end radious) radius)  from --ref-- and calculated using equation --crossref--. It is important to note that the over estimate of radious radius  slightly reduces the strain value, but does so linearly over all samples. -- GS equation, and maybe image? -- 

-- VS equation --  Narrow sense heritability for all properties was calculated using equation -- ref-- The constant of 2.5 used was sugested suggested  by --ref-- due to the unknown amount proportions of selfing, full siblings and half siblings within the families (refered (refereed  to as half sibling families). --H2 equation--  Analysis was conducted in R (--ref--) and JAGS (--ref--), utilizing a bayesian Bayesian  approach to estimate the heritability of growth strain and other wood porperties. properties.  The effect of coppicing and section were included as fixed effects, while half sibling family and the indervidual individual  trees are included as random effects. Physically although all specimens were grown on the same site, they were grown during different time periods which was confounded by the orignating originating  genetics of the two populations and hence are included as the fixed effect, section. --mathematical discription description  of the baysian Bayesian  code--
