ter-height classes (d = điameter at breast height in cm., h = total height in m.) A. B. C, and D are the numbers of stems used for Schuberg´s Tables for »Derbholz« (timber ^> 7 cm. top điameter) for age classes ranglng 21—40, 41—80, 81—120, and over 120 years respectively; E and F are the numbers of stems representing the basis for the preparation of volume table for Silver Fir at Zalesina on the silicate and calcareous parent rook. Table 2 gives the parameters for the Schumacher-Hall´s equation used for the smoothing of 5 Schuberg´s tables as well as for 2 tables from Zalesina. Table 3 gives an extract from different tables (đ = điameter at breast height in em., h = total height in m.); information given refers to the volume in cu. m.; A, B, C, and D refer to Schuberg´s Tables for »Derbholz« (Derbholzmassentafeln«); E means Schuberg´s Table for the total volume including needles (Baumholzmassentafeln «); F and G mean stem volume (»Schaftholz«) for Silver Fir from Zalesina (Experimental forests of the Zagreb Forestry Faculty) obtained on silicate (evenaged forest) and on calcareous substratum (selećtion forest). Tabels 4 and 5 represent the new — temporarv — volume tables for Silver Fir on silicate parent rock (even-aged type of forest) and on calcareous parent rock (selećtion type of forest) respectively, (d = điameter at breast height over bark in cm.. h = total height in m., m = stem volume with bark in cu. m.). The stump height is equal to 1/3 of d. b. h. |
