    Opis:
    The paper presents the literature review concerning the general assumptions of the Data Envelopment Analysis (DEA) and its applications in forest management and wood industry evaluation. So far, efficiency evaluation in forestry sector was carried out using mostly the ratio analysis only. The DEA approach, which was developed in the 1970s, is based on the mathematical programming algorithm and gives more opportunities to analyze efficiency in forestry sector. We describe the main steps of DEA and possible options for the analysis. It also discusses the advantages and disadvantages of the method applications. We also present the most significant papers concerning DEA application in forest management and wood−based industry. As far as forest management is regarded, DEA was used for evaluating forest offices, administration and institutions and optimizing forestry operations performed by both private and state−owned companies. In case of wood−based industry, the method was used mostly for evaluating efficiency of sawmills and pulp mills. Most of the research in this field was carried out in the United States and Canada. DEA was applied to measure efficiency in forest management in Poland only recently, which should be considered as a good step towards improvement of research quality in this field in Poland and should provide comprehensive results of forest management efficiency evaluation. The method should be used more widely to evaluate efficiency of various aspects of forestry and wood−based industry in Poland.

    Opis:
    The aim of this paper was to evaluate the financial and economic resources efficiency of forest districts in the years 2008−2012 using a nonparametric approach of the Data Envelopment Analysis (DEA). DEA is a linear programming based method for evaluating the performance of comparable production units such as firms. The relative efficiency of compared forest districts is calculated with the Variable Returns to Scale (VRS) model. Although the method is already extensively applied in many areas of economics, its use in forestry remains limited. We studied 110 forest districts from Wrocław, Katowice, Kraków and Krosno regional directorates of the State Forests. The research was conducted in groups of forest districts according to the similar forest site type, which ensured the homogeneity of the units and the comparability of research results. Two categories of the forest districts were identified: ‘lowland' and ‘upland−mountain' ones. The study covered selection of input (efforts) and output (results) variables as well as selection of appropriate DEA model, which were used to evaluate technical efficiency of the forest districts. Within the so−called model of economic resources they were quantified in technical units, whereas in a financial model – in value terms. The research shows differences in the use of economic and financial resources by the analyzed forest districts. The ‘lowland' were more effective than ‘upland−mountain' ones both in terms of the use of the financial and economic resources. Average relative efficiency in a financial model for the ‘lowland' forest districts amounts to 0.896, while for the ‘upland−mountain' ones – to 0.839. In economic resources model this parameter equals 0.853 and 0.823, respectively. The DEA method may be an alternative or complementary to other methods of evaluation of the forest district efficiency. Any attempt of such analysis may be very valuable support in the forest management.

    Opis:
    The article presents the results of research on the opportunity costs related to establishment of perennial bird protection zones in forests located in two randomly selected forest districts of the Mazowieckie Province: Grójec and Zwoleń (Regional Directorate of the State Forests in Radom). The analysis included calculation of profits lost by forest districts due to termination of timber harvest in bird protection zones and also estimation of work places lost as a result of introduction of new limitations (social costs). The analysis was conducted based on the assumption that currently protected tree stands within protection zones would have been managed in a regular manner, i.e. that pre−commercial and commercial thinning, as well as final cuttings would have taken place and that they would have been a source of income to the examined forest districts. Based on the characteristics of tree stands within protection zones derived from the forest management plans for the forest districts at stake, potential thinning and cutting volumes for a 10−year period as well as potential incomes from timber sale were determined. The calculated timber volume was also used for estimating labour intensity of timber harvesting and skidding. Establishment of perennial bird protection zones generated losses in timber harvest in the amount of about 24.6 thousand m³ during the period of 10 years, which equals to about 1.7% (Grójec) and 2.2% (Zwoleń) of planned timber harvest amounts stated in the forest management plans of the studied forest districts. Total opportunity costs were equal to 3478 thousand PLN during 10 years or 1313 PLN/ha of protection zone annually. Annual opportunity costs calculated per unit of forest area of the forest districts were equal to 11.56 PLN/ha. The estimated loss in work places was 0.85 full−time jobs annually per every 100 ha of perennial bird protection zones. Results show that economic and social costs of nature protection activities concentrate in places of their origin. Those costs are felt the most by owners of affected forests and local communities. Exploration and introduction of instruments allowing mitigation of negative effects resulting from restrictions in forest use are therefore recommended.

    Opis:
    The paper analyses direct costs of nature conservation and biodiversity protection incurred by forest districts of the State Forests in the Mazowieckie Province in the period 2008−2011. It also examines sources of their financing. The study shows that the largest amount of money – 65% of all costs – was spent on a wide range of activities related to biodiversity protection. The most significant fund donors were forest districts themselves. They provided 68.3% of all resources for nature conservation and biodiversity protection. The research also shows that funds received for these purposes from the state budget are rather of secondary importance.

    Opis:
    The objective of the study was to estimate the number of jobs created by sector of wood biomass used for the energy production. The study presents direct employment (the persons who are employed in the production of wood biomass, its harvesting, industry processing, transport or combustion), indirect employment (the employment in the related sections according to Polish Classification of Activites) and induced employment (the jobs created as a result of purchases of the persons directly employed in the biomass sector). The data used in the analyses were obtained from various official sources and statistics as well as previously published studies. The calculation included the whole area of Poland and focused on the data from the year 2012. The results lead to the conclusion that the direct employment in biomass sector in Poland in the year 2012 amounted 15.6 thousand jobs, of which 5.3 thousand in fuelwood harvesting and using. The indirect employment varied between 19 (by forestry sector) to 25 people (by public utilities sector) per 10 million PLN purchases by biomass sector. In turn, the induced employment amounted to 1.8 thousand employees, of which the largest share was observed for the education services section (29%), the manufactured products (19%), and human health services (17%).

    Opis:
    The article examines taxes, fees and other payments that are incurred by the State Forests National Forest Holding (SFNFH) on the example of the Drewnica Forest District (central Poland) in period 2008−2012. Fiscal instruments are shown against the results of the operations carried out by the forest district, while considering natural and economic conditions and various functions (e.g. environmental, social) performed by the entity, as well as any additional costs incurred during the implementation of these functions. The balance sheet reports, financial statements and other financial and accounting documents, including the planning documents of the examined forest district, constitute the data source for this study. Over the five−year period, the Drewnica Forest District paid an average PLN 839,000 in taxes and fees per annum, and this amounted to approximately 6.1% of its revenue (including the contributions made by the forestry fund). The largest share of the tax paid was composed of VAT (PLN 479,000) and forestry tax (PLN 167,000), as well as income tax from individuals (PLN 129,000). Other relatively small charges included PFRON contributions (PLN 45,000), property tax (PLN 16,000), agricultural tax (PLN 1,000), as well as the fees for the perpetual usufruct of land (PLN 3,000). Between 2008 and 2012, the revenue of the Drewnica Forest District was less than its expenses, and the additional payments in the form of taxes and other fees further increased its deficit. The analysis of the level and structure of taxes and other fiscal charges is important in the context of maintaining the statutory requirement of the financial independence of SFNFH. Studies reveal that the structure and level of financial charges imposed on the organisational units of the State Forests should be subject to the specific nature and conditions of the forestry production process. The imposition of excessively restrictive financial charges in the form of various taxes, fees and payments, made mostly to the State Treasury and municipalities, could threaten the economic viability of the State Forests.
