Similar trends were observed for basal area and whole-tree volume development. A Schumacher equation with local slope parameter and asymptote bounded at 45&amp;nbsp;m gave the best fit for height, while a von Bertalanffy-Richards equation in difference form with local slope parameter gave the best fit for basal area. For plantations with an average site index (20.4), height was predicted to be 22.3&amp;nbsp;m in height at age 60, with a basal area of 78.1&amp;nbsp;m&lt;sup&gt;2&lt;/sup&gt;&amp;nbsp;ha&lt;sup&gt;?1&lt;/sup&gt;. Whole-tree volume was predicted to be 702&amp;nbsp;m&lt;sup&gt;3&lt;/sup&gt;&amp;nbsp;ha&lt;sup&gt;?1&lt;/sup&gt;. Predicted volume mean annual increment was 11.7&amp;nbsp;m&lt;sup&gt;3&lt;/sup&gt;&amp;nbsp;ha&lt;sup&gt;?1&lt;/sup&gt;&amp;nbsp;yr&lt;sup&gt;?1&lt;/sup&gt;for all stands at age 60. From age 20-60 years, stands with a higher site index had a volume mean annual increment of 18.6&amp;nbsp;m&lt;sup&gt;3&lt;/sup&gt;&amp;nbsp;ha&lt;sup&gt;?1&lt;/sup&gt;&amp;nbsp;yr&lt;sup&gt;?1&lt;/sup&gt;. The best stand exceeded 20&amp;nbsp;m&lt;sup&gt;3&lt;/sup&gt;&amp;nbsp;ha&lt;sup&gt;?1&lt;/sup&gt;&amp;nbsp;yr&lt;sup&gt;?1&lt;/sup&gt;.&lt;/p&gt;&lt;h4&gt;Conclusions&lt;/h4&gt;&lt;p style=&quot;line-height: 160%;&quot;&gt;This study indicates an opportunity to grow kauri in plantations on selected good-quality sites over rotations of 60-80 years or less.&lt;/p&gt;&lt;/div&gt;</style></abstract><issue><style face="normal" font="default" size="100%">27</style></issue></record></records></xml>
