The paper presents assessment of the value of selected beech and fir stands by the classic method and using the value tariff in two ways. The aim of the work was to verify the suitability of the local tariff method based on the SILP forest database for the valuation of timber resources in forests. The measurements were carried out in the Beskidy Mountains (southern Poland). The reference sales value...
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...
Statistical representative method of inventory based on stratified sampling is used for elaborate forest management plans in Poland. Strata are created according to the dominant tree species and age of stands. First stratum include stands with age from 21 to 30 years and the interval in the next strata is 10 years. Sample plot size depends on stand age and varies from 0.005 to 0.05 ha. According to...
The study describes a new method of assessing the average age of the forest range with significant share of stands in the regeneration class. In proposed method, average age of stands in regeneration layer is calculated as a mean age of tree layer as well as layer of upgrowth, recruitment and saplings weighed by these layers fraction. Example of calculation of average age was performed for 7 ranges...
