    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 article presents research on the management and supervision of forests located within cities in the Mazowieckie Province. The information was obtained from questionnaires sent to all 85 city authorities in the province. The questions were related to organization and supervision of forests, forest management and protection, recreational management and financing of forests, as well as main problems associated with the management of urban forests. The research indicated that forests, which altogether cover more than 10% of city area, have a very important function, despite the forest area per resident being very small. The difficulties in forest management may arise due to their highly fragmented distribution as well as the mixture of many different types of forest owners. Moreover, communal forests in the province's smaller towns lack proper management and protection structures and lack recreational facilities as local infrastructure is poorly developed. These sort of activities are conducted only in larger municipalities. Most of the non-state owned forests within cities have simplified forest management plans, which counts as a big plus for the Mazowieckie Province when considered in the context of the whole country. Certain measures should be taken to improve the condition of urban forests in the Mazowieckie Province, and serve to preserve and protection these forests. It is fundamental that city governments should cooperate with as wide as possible a circle of interested parties, to undertake common activities in forests of various ownership types located within each given urban area. Additionally, all feasible sources of financing should be considered.

    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 article presents the results of research on the opportunity costs related to establishing nature reserves in four randomly-selected forest districts located in the Mazowieckie Province: Celestynów, Grójec, P³oñsk and Zwoleń. Our analysis included calculation of profits forgone by forest districts due to the cessation of timber harvesting in nature reserves and an estimation of work places lost as a result of introduction of new limitations, as well as the expenses incurred by municipalities related to their establishment of forest tax concessions in nature reserves. The establishment of nature reserves incurred losses related to timber harvest of about 246 thousand m3 during the period of 10 years, which is equivalent to between 4.1% and 19.8% of the planned timber harvest stated in the forest management plans of the studied forest districts. Total opportunity costs were equal to 25.5-27.2 million PLN during these 10 years or 1502-1605 PLN/ha of nature reserve annually. Annual opportunity costs calculated per unit of forest area were equal to 56-60 PLN/ha. The estimated loss in work places was 98.8 working days annually per 1000 ha of forest area in forest districts. Total expenses incurred by municipalities related to establishment of forest tax concessions in nature reserves reached about 18.1 thousand PLN in 2011. The research results show that the economic and social costs of nature protection activities are concentrated in their places of their origin. Those costs are felt the most by the owners of the affected forests and local communities. We recommend that possibilities are explored for the introduction of instruments to allow the mitigation of negative effects resulting from restrictions in forest use. Restructuring of forest and nature protection policy, to take into account the interests of all stakeholders would provide an improved model for the use of these forests.

    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 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%).
