Opis:
The aim of the study was to determine the impact an increased wood supply from the Beskid forests after natural disasters on the timber economy of the Węgierska Górka Forest District and its surroundings in the years 2004–2010. The analysis was based on the wood raw material sales recorded in the database of the State Forestry Information System (SILP). Information on the buyers’ location and their main use for the raw material were obtained through the Central Statistical Office. Furthermore, wood material buyers were classified according to the Polish Classification of Activities (PCA) based on the year 2007, using only a subjective analysis designed for enterprises and other economic units in the national economy. Changes in sales of wood material to the selected buyer groups were investigated using statistical analyses of linear trends. A Pearson’s correlation analysis verified the relationships between the buyer groups and the supply of timber assortments by the Węgierska Górka Forest District. Other studies have also shown that an increased supply of raw material in the context of natural disasters affects the types of wood buyers and their location. In addition, they have shown an increase in interest towards the purchase of raw materials among buyers engaged in the wholesale trade of wood and other non-wood producers which in turn decrease the share purchased by sawmills.

Opis:
The aim of the study was to determine the impact of increased timber logging after natural disasters on timber assortments, unit prices, as well as average prices of timber spruce and total timber. The net sales prices of the years 2004-2010, available from the database of the State Forests Information System (SFIS) for the Forest District of Węgierska Górka, were analysed and compared to the prices of selected forest districts within the Regional Directorate of State Forests in Cracow (RDSF). The forest districts were classified based on the volume of logged timber leading to a separation into two groups of two and six forest districts. Moreover, we tested for significance in the linear trends of relevant characteristics and determined confidence intervals. Furthermore, we calculated the rate of growth (decrease) of the unit prices. Our studies show a decrease in price of only some of the timber assortments despite a significantly increased supply. Price declines were observed for the average prices of timber spruce and total timber due to their lowered quality. The price of timber assortments was mainly determined by effects of macroeconomic factors.

Opis:
The research concerned the implementation of tasks in the field of harvesting timber in 2008−2012 in pure pine stands aged 10−140. Numerical data from the SILP database were used for calculating the average price of timber in the intermediate harvest. The data on the volume harvested covered late cleaning, early thinning and late thinning. The assortment structure concerned the following groups of large− (WA0, WA1, WB0, WB1, WC0, WC1 and WD), medium− (S10, S11, S2A, S2B, S3A, S3B and S4) as well as small−sized (M1 and M2) assortment groups. The data on the size and value of wood assortments sold across the country concerned the year 2011 and were used to calculate the average price of wood in age subclasses according to the site quality described with site index class. Subsequently, for each site quality class polynomial equations of the trend line was determined and average timber price for each age subclass was calculated for small−, medium− and large−sized assortments. The analysis showed that S2 is the most frequently harvested assortment in the intermediate cuts in Scots pine stands, whose share depending on the site quality class is at the level of 65.7−72.7% of total harvest. The share of small−sized assortments decreases with age in all site quality classes. The opposite tendency is seen for large−sized assortments, whose share decreases with the deterioration of the site quality. Fraction of medium−sized assortments reaches its peak at the age of ca 45 in IA site index class and the shift in the peak with age is associated with the deterioration of the site quality. The higher the site quality, the higher the prices of assortments in the intermediate harvest. This trend occurs in all age subclasses.
