    Opis:
    The article analyzes the possibility of using a seven−year development trend model to forecast the average price of wood sales (CGUS). Price models and forecasts were made on the basis of three different time series covering 7−year periods. The forecast of timber prices in individual years was developed on the basis of extrapolation going beyond the set of information adopted for research used to build the development trend model. We found that the size of the indicators of determination of the analyzed functions ranged from 0.5 to 0.6, and the convergence rates from 0.5 to 0.4. This means that the linear functions were characterized by poor adjustment to real prices. Despite this, the timber price forecasts differed from the empirical prices from PLN 1.81 to 13.91. In relative categories, the forecast error was in the range from 0.92 to 7.28%. Therefore, in our opinion, the research process presented can be a reference point as a comparative element to verify forecast results for other (non−linear) price forecasting models. The process of modeling timber raw material prices should be extended to other predictors related to the forest marketing chain. The predicted results from these models cannot be worse than those obtained by forecasting using linear functions

    Opis:
    The paper analyses the amount of cut, the assortment and species structure of the current domestic market for timber of the highest quality classes (wood veneer, plywood, telecommunication poles) in Poland in years 2005−2009. Oak and beech are the main source of material for the production of veneer in Poland. Sales of oak veneer in 2005−2009 amounted to 17,502.9 m3 (35.8% of the total sales of assortment WA1). Sales of beech veneer in 2005−2009 amounted to 11,233.5 m3 (23.0% of total sales). Among the plywood assortments harvested in Poland in 2005−2009, birch was harvested and sold in the largest quantities – 503,870.0 m3 (39.1% of total harvest) and 590,822.4 m3 (43.8% of total sales). Of all the regional directorates of the State Forests, the Krosno RDSF showed in 2005−2009 the largest harvest of WA1 assortments – 9734.0 m3 (21.4% of the total harvest), and sale – 9611.0 m3 (19.7% of total sales). Because of the large beech and sycamore timber resources, forests in the Krosno RDSF are a main current and potential source of veneer assortments. Because of the large amounts of harvested and sold oak, beech, pine, birch and alder veneer the Białystok, Olsztyn, Szczecinek and Szczecin RDSFs play the dominant role on the Polish timber market. The leading role in terms of plywood sales in the period under review was taken by RDSFs Olsztyn – 24.9%, Białystok – 26.2%, Szczecinek – 13.1% and Szczecin – 11.6%. These RDSFs taken together supplied to the market 75.8% of plywood, being the main material base for the plywood industry. The dominant role of these RDSFs derives from the fact that forests under their administration are rich in birch, alder and pine. Spruce as a plywood material is insufficiently used by the plywood industry (harvest – 33,269.9 m3, sale – 579.5 m3).

    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 article presents an analysis of the birch market in Poland in 2008−2012, including the acquisition (supply) of birch wood, the income structure, prices of birch wood, the structure of birch wood recipients and the volume of purchased timber. The necessary materials were obtained from the Forest Data Bank (BDL) and the State Forests Information System (SILP). The S2 wood assortment representing more than 54% of all assortment groups is most often harvested in Poland. Next come M1 representing 14%, as well as S4 and WC – each with share slightly exceeding 11%. The vast majority of the harvested and handled birch wood is in the group of medium−sized assortments S representing 66%, and in the group of small−sized assortments M representing 14%. Birch wood classified as large−sized W totals 20%. Similarly, timber assortments from group S2 also generate the largest portion of revenues (over 50% of total revenues from birch wood sales). High fluctuations in the prices of certain groups of birch wood assortments constitute a significant problem from the point of view of both the State Forests and wood consumers. A possible reduction in the supply of wood of this species in the future may deepen this phenomenon. Average sales prices of birch wood on the Polish market are lower than the prices obtained by timber producers in the neighbouring countries. The price differences in favour of foreign timber producers reach up to 20% and relate to roundwood in different quality and size classes. The exceptionally high technical quality of birch wood in our country does not translate to higher prices per cubic meter of raw timber in the domestic turnover. The sharp increase in the demand for a special type of fibres for the manufacture of many products characterized by exceptional strength (i.e. products from polymers) and textiles with special insulating properties, as well as the production of certain grades of paper and board, will stimulate the consumption of birch wood in the future.
