    variation in timber prices
    Opis:
    The objective of the study was to identify and analyze long−term trends as well as cyclic, seasonal, and irregular effects in timber volume and prices by means of time series decomposition. The adopted multiplicative model was the product of all the time series components identified using the Census X11 method. The study material consisted of quarterly data on the volume and prices of timber sold by the Marcule Forest District (central Poland) in the years 2006−2018. Analysis was performed for the overall timber production volume, as well as separately for pine timber (constituting 86% of the total) and oak timber (5%), taking into account large−diameter saw timber (WC0) and medium−diameter industrial and general purpose timber (pulpwood, S2A). Over the analyzed period, the nominal prices of timber rose on average by 39% from 165 to 229 PLN/m3. The greatest price increase was recorded for large−diameter oak timber (by 100%), while the prices of WC0 pine timber, which accounted for the greatest proportion of the production volume, increased by 23% on average. Production characterized marked seasonality throughout the year, depending on the species. Pine timber sales were the lowest in 1st quarter and the highest in 3rd one, while oak timber sales were the lowest in 3rd quarter and the highest in 4th one. The seasonal effect accounted for the largest proportion of variation in timber production volume. The seasonality of timber prices was negatively correlated with production. The highest prices for pine and oak timber were obtained in 1st and 2nd quarters respectively, when the production volume of those timber species was the lowest. Conversely, the lowest prices were recorded in seasons characterized by the greatest production volume, i.e., in 3rd quarter for pine and in 4th quarter for oak. The decomposition of overall variation in timber prices into its components, which can be predicted (cyclic and seasonal fluctuations as well as long−term trend), and those that are difficult to forecast (irregular effect) is of great significance for timber sales management as the results can be used to improve timber price forecasting.

    Opis:
    The analysis of the sales methods and prices of the highest quality timber (wood veneer, plywood and telecommunication poles) was based on the data obtained from the General Directorate of the State Forests covering the period 2005−2009. They were supplemented by the data on sales, prices and revenues from sales, auctions and submissions obtained from the Regional Directorates of the State Forests (RDSF) in: Szczecin, Poznań, Białystok, Krosno and Lublin. The results of the submission sales organized by the Krosno RDSF and auctions organized by the Poznań RDSF in 2005−2009 were also analysed. The analyses confirm that sales of the highest quality wood through auctions and submissions give the best economic results while ensuring the optimal use of the existing resource base. Both sales methods foster rational use of valuable wood and therefore should be adopted in other RDSFs. In the years 2005−2009, the difference (increase) between wood valuation and the derived income from the auction sales organized in the Poznań RDSF amounted to 39.6%. The difference (increase) between wood valuation and the derived income from the submission sales organized in the Krosno RDSF in the same period amounted to 80.1%. The maximum prices of wood veneer obtained through auctions and submissions are higher than the prices obtained via Internet sales. Among the WA1 assortments sold in Poland in the years 2005−2009, sycamore, maple, and cherry veneer reached the highest average price per cubic meter. Among the wood species from which veneer is produced, oak veneer is the most sold species. Among the WB1 assortments sold in Poland in the years 2005−2009, pine and spruce plywood reached the highest average price per cubic meter. The prices of birch, beech and alder plywood were lower and varied by a maximum of 6.7%. Among the species from which plywood is produced, birch plywood sells bests.

    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.
