Growing stock levels and productivity conclusions from thinning and spacing trials in young Pinus patula stands in Southern Tanzania
<p>Data from six experiments laid out to test the effect of spacing and growing-stock level on the growth of <em>Pinus patu1a</em> to age 15 on the southern Highlands of Tanzania have been summarised and analysed. Increased stand density resulted in increased total volume productio...

| description | <p>Data from six experiments laid out to test the effect of spacing and growing-stock level on the growth of <em>Pinus patu1a</em> to age 15 on the southern Highlands of Tanzania have been summarised and analysed. Increased stand density resulted in increased total volume production and reduced mean tree size, with no clear effect on height growth.</p> <p>A close relation was found between mean size· and volume increment and Assmann's 'relative basal area', an index of stand density. The results are summarised for one site class in the form of a variable density yield table where density is defined either as stocking (N ha<sup>-1</sup>) or as relative basal area (G%).</p> |
