inventory of wood resources - Opis:
- This paper presents the method worked out to assess the value of growing stock in an exemplary forest district basing on the stand−level data available from the forest inventory databases. The method was designed for European beech and silver fir growing in the Polish part of the Carpathian Mountains. Sample data includes 28 stands, where quality classes of wood were assessed for 18,000 trees altogether. Beech and fir timber prices from the transactions made in 2010−2012 and harvesting/processing costs were also included in the analysis. The proposed tariff consists of calculating the growing stock value basing on taxation features of the stands, which are described in the forest management plan as well as on local wood stock prices. The local tariffs of wood stock prices for beech and fir were calculated as a set of functions, where the diameter at breast height (DBH) is the descriptive variable. The local tariff for beech with DBH in the range of 7−22.5 cm equals approximately 89.6 PLN/m³, while for DBH in the range of 22.5−50.9 cm is described by the equation: y=–0.011·DBH²+1.9539·DBH+51,305. The local tariff for fir wood with DBH in the range of 7−18 cm amounts approximately to 99 PLN/m³, while for DBH in the range of 18−54.2 cm is described by the equation: y=0.0027·DBH³–0.3555·DBH²+15.992·DBH–80.186. The initial verification of the valuation results obtained by means of this method turned out to be positive. As the next stage, the presented method should be verified for the same stands with use of several methods, e.g. quality classes of wood and calculating the value of the cut wood and calculating valuation errors.
