    Opis:
    The aim of this study is to assess the economic efficiency of forest management based on the revenues and costs of selected activities and the financial result of the forest districts within the ‘Puszcza Białowieska’ Forest Promotional Complex (FPC), i.e. Białowieża, Browsk and Hajnówka forest districts. The assessment of the economic efficiency of the forest management in ‘Puszcza Białowieska’ FPC forest districts was analyzed in relation to the average values for comparative units (28 other forest districts) included in the Regional Directorate of State Forests (RDSF) in Białystok. In this study the profit and loss account and the basic reporting document on financial and economic activity (LPIR1) for the years 2011−2017 were used. Data were collected from the State Forests Information System. A detailed analysis of revenues and costs (from the sale of products, goods and materials), including administrative, basic, side, additional and social−living activities, as well as general administrative costs was made. The financial result of the FPC forest districts was also analyzed and then modified by increasing the net result by the value of the write−off for the forest fund and the maintenance costs of the superior units and reduced by the additional payment from the forestry fund. The amount of financial results of ‘Puszcza Białowieska’ FPC forest districts is mainly determined by revenues from the sale of woody raw material. Other types of activities do not have a significant impact on improving the financial result of these entities. The actual financial situation of ‘Puszcza Białowieska’ FPC forest districts reflects the modified net financial result, including for funds from the forest fund. Implementation of tasks in the field of nature protection and restrictions resulting from the acquisition of timber in ‘Puszcza Białowieska’ FPC forest districts significantly worsen their financial result. Implementation of additional tasks in the field of nature conservation causes a deterioration in the economic effi− ciency of forest management, which suggests extending the analyzes of other forest districts of the State Forests.

    Opis:
    The aim of this study is to assess the economic efficiency of the forest management with particular emphasis on economic and financial indicators of the forest districts (namely Białowieża, Browsk and Hajnówka) constituting the ‘Puszcza Białowieska’ Forest Promotional Complex (FPC). The work involved analysis of indicators reflecting the financial condition of the forest districts with reference to average values for comparison units i.e. 28 other entities from the Regional Directorate of the State Forests in Bialystok. The analysis consisted in the determination of typical values from comparative units in individual years (mean ±standard deviation). The balance sheet, profit and loss account and basic reporting document on financial and economic activities (LPIR1) for the years 2011−2017. Data were collected from the State Forests Information System. Financial liquidity, profitability and management efficiency were analyzed in detail. The net financial result of the forest districts was used for the analyzes, after an additional adjustment, consisting in increasing the net result by the value of the write−off for the forest fund and maintenance costs of the superior units and reduced by the additional payment from the forest fund. The analyzes were based on data collected from the State Forests Information System. On the basis of the research, it was found that the rules of financial management in the State Forests do not pose a risk of deterioration or loss of financial liquidity of the FPC forest districts. However, the inability to obtain the additional payment from a forest fund by individual of FPC forest districts would result in the loss of their ability to function independently. The management efficiency clearly affects the actual financial situation of the FPC forest districts. The deteriorating profitability of the FPC forest districts is caused by negative (loss) net financial results reflects the modified net financial result, including for funds from the forest fund. Restrictions on harvesting, resulting from the implementation of tasks in the field of nature conservation, worsen the economic efficiency of the FPC forest districts.

    assortment and species structure
    Opis:
    The structure of timber sales in forest districts of the Białowieża Forest in the years 2008−2015 is presented. The Białowieża Forest is one of the most valuable natural areas in Europe. The data from the reports generated by the State Forests Information System of the Hajnówka, Browsk and Białowieża forest districts were used for the research. The information contained in the forest management plans and nature conservation programs of the surveyed forest districts was also used. The volume of the sold merchantable timber in the Białowieża Forest amounted to 669,072 m3, of which 63.43% was softwood and 36.57% hardwood. Among the softwood assortment, sales of the large−sized timber amounted to 44.42%, while of the medium−sized timber to 55.58%. For the large−sized hardwood, the share of sales amounted to 30.66%, while for the medium−sized hardwood to 69.34%. The small−sized timber was sold at 22,389 m3, with the share of hardwood assortments being 82%, and of softwood 18%. A small share in the sales of small−sized timber is caused by the lack of FSC certification by forest districts, which excludes large industrial companies that buy predominantly the medium−sized coniferous timber assortments. The average price obtained from the sale of timber in the the Białowieża Forest in the analysed period was 134.7 PLN/m3. At a price higher than the average, wood was sold in the Białowieża and Hajnówka forest districts, while in the Browsk Forest District the timber was sold at a price lower than the average. The total volume of merchantable timber harvested in the forest districts of the Białowieża Forest in the analysed years, including the small−sized timber, amounted to 686,684 m3, with 691,461 m3 of timber being sold. The volume of the merchantable timber sold at that time was 669,072 m3, which constituted only 0.24% of the total timber sold at the State Forests in Poland.

    Opis:
    Abundance of red fox (Vulpes vulpes) populations in Poland and Europe have increased in the past decades, especially in the areas of high anthropogenic transformation. The aim of this study was to assess the current density of red fox in natural forests and to analyse changes in its abundance since 1981. The fieldwork was carried out in Polish part of the Bialowieża Primeval Forest (BPF), including Białowieża, Browsk and Hajnówka forest districts as well as Białowieża National Park. A standard method of snow tracking along transect routes (15 to 94 km long in the subsequent winters, altogether 199 km) was used. Taking a density of snow tracks per 1 km of a transect route per 24 h and the length of daily movements of red foxes (13,8 km) we calculated the population density. Results were compared with historical data derived with the same method. Mean number of tracks of red fox in the years 2011−2016 equaled 6.1/km/24h (SD=3.9). Density of fox population was 0.69 individuals/km2, which results in the abundance of the population in the whole area of BPF of 414 individuals in winter time, while of approximately 869 individuals in spring. Comparison of current data with the results from last three decades showed an increasing trend in the population of the analysed species. Nevertheless, in comparison to central or western Poland the density of the red fox in the BPF is still relatively low. Possible factors that suppress this population are parasites, infections (mange, rabies) and large carnivores.

    Opis:
    Stand damage risk model was applied to three forest districts located in the Białowieża Primeval Forest: Browsk, Hajnówka and Białowieża. For this purpose, information contained in the database of the State Forests Information System was used. The obtained values of the stand damage risk factor allowed assigning each stand to one of the six risk classes. Higher class indicates higher damage risk to stands. The share of the stand area was calculated for each class. The weighted average of the areal shares of stands in the two highest damage risk factor classes was used as a measure of wind damage risk to forests. The values of this measure for individual forest districts were as follows: Browsk – 27.3%, Hajnówka – 33.0%, Białowieża – 38.3%. The degree of risk to these forests ranges from average to high, which is mainly because of large proportion of the high, old−growth spruce stands. Forest stands of the Białowieża Primeval Forest with a high risk factor are threatened by damage in the event of strong winds in this area.
