ŠURIĆ´S INTERPOLATED ONE-ENTRY VOLUME TABLES FOR
FIR/SPRUCE AND BEECH


Summary


The one-entry volume tables — tariffs — become more and more required in
the European countries´ Forest management. In Yugoslavia´s Forest management are
largely used Šurić´s one-entry tables with five-tariff series for each individual
forest tree species.


Surić has constructed his volume tables by means of height curves obtained
by the strip method and the two-entry volume tables, and, in addition, he controlled
them through concrete test trees. Because of a too small number of tariff series the
tables produce a marked error when calculating the growing-stock volume of a stand.
Therefore were prepared Šurić´s new interpolated tables containing a greater number
(nine) of tariff series for an individual tree species and thus a greater possibility of
a more accurate stock-taking of a stand. The work was carried out graphically, i. e.
between Surić´s height and form-height tariff series were graphically interpolated
the new tariff series. The tariff series of tree volumes were computed on the basis
of the diameters b. h. and form heights.


Šurić´s interpolated tables were extended with derivations of the tariff series
of tree volumes and their relative values. Hence the tables render the computation
of the stand volume increment by Meyer´s method of tariff differences possible.


As the analytical expressions of the tree volume curves are not known to us,
we have computed for each diameter-class gradation of the individual tariff series
by means of tabular derivation the amounts of derivation (dv/dd), which — after a
graphical smoothing — we entered into the tables. The relative values of derivations


dv 1
(c = —) were computed from the graphically smoothed values of derivations
dd v


as well as the mean volumes of the corresponding diameter gradation within the
tariff series (Emrović, 2).
