Volume Estimation
- Stocking - a quantitative measure of the area occupied by trees relative to an optimum or desired level of density
- Stand Density Index - a measure of the stocking of a stand of trees based on the number of trees per unit area and DBH of the tree of average basal area
- Volume table - a chart based on volume equations that uses correlations between certain aspects of a tree to estimate the standing volume
- Stand density management diagram - model that uses current stand density to project future stand composition
- Volume can be calculated from the metrics recorded in a plot sample. For example if a tree was measured to be 20m tall and with a DBH of 19 cm using previous measured tree data a volume could be approximated according to species. Such a table has been constructed by Josef Pollanschütz in Austria.
Volume of tree = BA X h x f pollanschutz
So f pollanschütz would be derived from the table and is properly called the Form Factor.
To scale this up to a hectare level the result would have to be multiplied by the number of trees of that size. This is called the blow up factor.

Famous quotes containing the words volume and/or estimation:
“F.R. Leavis’s “eat up your broccoli” approach to fiction emphasises this junkfood/wholefood dichotomy. If reading a novel—for the eighteenth century reader, the most frivolous of diversions—did not, by the middle of the twentieth century, make you a better person in some way, then you might as well flush the offending volume down the toilet, which was by far the best place for the undigested excreta of dubious nourishment.”
—Angela Carter (1940–1992)
“... it would be impossible for women to stand in higher estimation than they do here. The deference that is paid to them at all times and in all places has often occasioned me as much surprise as pleasure.”
—Frances Wright (1795–1852)
