Opis:
Against the background of the solutions laid down in successive editions of Principles of forest management the paper presents their vital role in the shaping of the sustainable multifunctionality of Polish forests and forest management. It has been demonstrated that that the „Principles” of 1953/1955, which were based on ecological foundations and approached forest as an ecosystem, allowed to meet the economic and social goals of forest management. The subsequent editions of the „Principles” were open to any proposal that takes account of the nature and forest−related knowledge, as well as of social and economic conditions of functioning of the forest holding.

Opis:
Many attempts have been made to develop a strategy for regulating forest use consistent with the multifunctional forest model. In this paper we present two proprietary methodologies of regulation of the allowable cutting size in a multifunctional forest in the 60−year time perspective. We assumed that all restrictions of nature protection and non−productive functions of the forest would still be in force. We based the first method on age class tables (TKW), which is faster but less exact in terms of spatial order of felling. The tree stand method (D−STAN) is based on stands spatial order and the cutting direction basis. In both cases, we based the temporal felling order on species rotation age. Comparing the results, we noticed that they present similar trends in the age structure of tree stands in younger age classes. The main discrepancies of the forecast concerns the share of forest stands in a complex structure: the TKW method gave approximately 12,4%, while the D−STAN one produced 5,1%. The latter approach shows that much smaller areas of stands are used for reconstruction. That marker is influenced by the spatial order of cutting used in the D−STAN model. In conclusion, we suggest to return to the big−area clear−cutting system on fresh coniferous habitats. Medium−area clear−cuttings should be brought back on the least fertile fresh mixed coniferous forests and possibly even fresh mixed deciduous forests.

The paper provides the framework programme for the courses on forest hydrology that have been conducted in the Department of Forestry in the Agricultural Academy in Cracow since 1994. The objective of the paper is to present this programme including indispensable explanations justifying the adopted solutions. Water relations in a forest are described from the "position of the interior of a forest" i.e. with reference to the circulation of water between atmosphere, stand and soil determining the dynamics of the water content in the soil. At the same time, the changes in water content in the soil are the result of the modelling effect of forest vegetation.

Opis:
Forestry education at university level has a long and rich tradition, dating back to the nineteenth century. Since then there have been many fundamental changes both in defining the objectives and methods of education of foresters−to−be, because conducting education in the rapidly changing forest management requires a continuous adaptation of the curricula to the requirements of the development of civilisation. The challenge of forest education at the university level in the twenty first century is to find appropriate educational ways and tools referring to the paradigm shift expressed by the transition from teaching to learning, also as a constant process. Presentation of clear and effective methods of evaluating the quality of education and competencies acquired by graduates of university studies forest is of a great importance as well.

Opis:
In Poland, the public believes that the main objective of urban forests is rather to conduct forest management focused on the recreational needs of residents than to produce timber. Considering this belief, it becomes reasonable to distinct the principles of forest management in urban forests from those related to the forests of the State Forests National Forest Holding. Because of the permanent presence of people in the city woods, the managing authorities of such areas should also educate the residents, while forest management should be subordinated to social functions, especially the recreational one. However, Poland lacks the unified system of managing the urban forests, not only at the national scale (there is no central independent organizational unit), but also at the level of individual cities, where various municipal units manage urban woodlands. In practice, each city has its own, individual solutions in this regard. The governing bodies of urban forests face with many problems in their activity. These problems are associated with a strong process of urbanization and human pressure on forest areas, while on the other hand there are no formal legal basis (laws, regulations, instructions) relating the municipal forests. The paper reviews the literature on urban forestry and urban forests worldwide to present the existing legislative frameworks and to propose some changes, based on the current Act on Forest. It was stated that urban forestry in Poland is located in its ‘narrow' definition, based on the traditional forestry, giving priority to the multiple social functions. The proposed changes in forest legislation are part of the discussion on municipal forests and urban forestry in Poland, aiming once again to draw attention to the fact that they are almost ignored in the Polish legislation. The indicated areas for improvements and supplements suggest issues the most important and urgent to solve, but they are not a comprehensive solution on this subject. In order to strengthen the supervision of urban forests in Poland, it is essential to consider the restoration of central supervision, coor− dinating activities of urban foresters by the development and implementation to the practice unified legal regulations, as well as to give wide autonomy to cities.

Opis:
The beginnings of private forest services sector date back to the interwar period when harvesting operations and sawmill services were carried out by private companies leading to forest devastation. Adam Loret, the first director−general of the State Forests, started to build the structure of forest administration and hire manual workers. After the World War II, forestry in Poland operated in a centrally planned economic system, which precluded the functioning of the private forest services sector. The development of private forest companies in Poland began in the early 1990s. The employed free−market economy forced the State Forests to introduce many reforms and modifications to forest management, forest operations, as well as to the trading and sales of timber. All forest operations are being outsourced to private forest companies. Forest districts select bidders to perform the required forest operations according to the existing procedures, while ensuring the favourable conditions for the creation of new jobs. Forest companies face many difficulties to meet the growing demands laid down by the forest administration staff in tender specifications. The paper presents the current status of the private forest services sector, and describes the trends in the development of private forest companies providing services to the State Forests.

Opis:
The development and the decline of forest railway networks in Poland are still poorly investigated by scientists. Unfortunately, the availability of data is limited, therefore paper is focused on the period after the Second World War. In this time almost 40 forest railways were exploited. A synthetic review of the history of the most of them is carried out on the regional basis. The main reasons of the forest railway networks development includes massive harvest done in the forests by the occupants and the lack of paved roads in forest areas. The reasons of the decline of the network were similar as in the case of sugar beet railways: exploitation of the rolling stock and infrastructure, supply problems and the development of alternative means of transport, as well as the outflow of workforce and declining availability of wood sources near the railway tracks, which resulted in increasing costs of haulage. In some regions of Poland the restrictions in use of forest railways are also caused by the preservation of the natural environment.

Article describes Prussian forest policy according to three kinds of property: state, private and other, i.e. Catholic Church and local communities. In period 1772−1914, in the contemporary western and northern Poland, the Prussian government realized the forest policy that was a response to industrial challenges. It established a stable infrastructure, which lasts until now. However, the consequences of this policy are not unequivocal. Citizens who belonged to the Polish national community very often lost their forest property. Prussian state became the main owner and manager as well as administrator of forests.
