What is the Real Amount of Fir Stocks in Croatian Forests?     pdf     HR     EN 185
Summary: Various volume tables have been used in forest management so far to determine the growing stock. In calculating the growing stock of fir in the period 1945 - 1994, the tariffs by the following authors have been used: Šurić, then Šurić-Pranjić, and finally Špiranec. The use of local tariffs was prescribed by the Forest Management Act of 1994.In this paper, the author compares the tariffs and the stocks calculated with these tariffs so far with local tariffs and the stocks calculated with them. Two management units with two stands each were selected for the purpose of research. The stands in the management unit “Milanov Vrh” have uneven structures and those in “Crni Lug” have a transitional uneven structures.
Špiranec´s tariffs follow local tariffs up to the diameter degree of 52.5 cm, but after that the former become distinctly steeper than the latter. As breast diameter increases, the difference becomes more pronounced both in the absolute and percentage amount. The overall stock deviation calculated with Špiranec´s tariffs in relation to that calculated with local tariffs depends primarily on the distribution of tree numbers. The more trees in the diameter degree above 52.5 cm, and the more trees in higher diameter degrees, the greater the deviation. Consequently, the value of stocks calculated with Špiranec´s tariffs is questionable, particularly in stands and management units with a large number of thick trees (transitional uneven structures).
The local tariffs of the studied stands fit well into the Šurić-Pranjić tariff series, allowing for the half site class shift. The overall stock deviation calculated with Šurić-Pranjić tariffs in relation to the stocks calculated with local tariffs depends on the integration of the real height curve into the height curve of the Šurić-Pranjić site class, as well as on the differences in the two-parametre tables serving as bases for local tariffs.
