Opis:
The Republic of Poland for centuries has been one of the most forested European country and remains to now, as evidenced of this is the fact that Poland has the sixth largest forest in the European Union (data for 2014 years). Same, the fact of having a one of the largest forest areas makes their placing particular type of tax is an interesting issue and a matter that should be carefully analyzed.

Opis:
Forests in Poland cover about 30% of the country’s area; most of them are public forests managed by the State Forest National Forest Holding. Some of them have protection status in order to perform specific functions related to their location. One of the essential categories of protection forests is located within the administrative borders of towns and near areas with more than 50,000 inhabitants. Such areas are significant from the social point of view, and their primary function is to create proper space for the inhabitants’ leisure and biodiversity protection. However, management in forests around towns is increasingly controversial, which in the area of the Regional Directorate of State Forests in Bialystok is manifested by more and more frequent conflict situations. In order to meet social expectations while effectively ensuring the continuity of the forests for future generations, a change in the way of forest management in and near cities is necessary. The key element is probably to develop a dialogue model with the local community to manage socially important forests efficiently and mitigate emerging social controversies.

Opis:
The illumination under the canopy in different types of pine and spruce forests is considered. The research was carried out in different points of the Northern taiga of the Arkhangelsk region. Illumination was measured using a luxmeter in different directions: at the level of the moss-lichen layer, at the level of the grass-shrub layer and at a height of 1.3 m; at different distances from the tree trunk; at different distances from the edge of the forest. Illumination in pine forests at the level of the moss-lichen layer is 2.3 times higher than in spruce forests. Under the canopy of spruce forests, it is 1–3%, and in the pine forests, 3–9% of the illumination in the open. Illumination from tree trunks to the edge increases in pine and spruce forests equally. The lowest illumination is observed at the level of the moss-lichen layer, then it increases to the grass-shrub layer, and then practically does not change. However, the difference between pine and spruce forests is consistently high 47%. The decrease in illumination in the tree stand as it moves away from the edge in blueberry pine forests is observed up to a distance of 10 m from the edge, and in blueberry spruce forests up to 6 m.

Opis:
The study deals with the determination of the capital structure of the forest districts of the Regional Directorate of State Forests (RDSF) in Poznań in years 1998-2001. In the performed investigations the author utilized indices of the capital structure and indebtedness indices of the owners' equity. In addition, the author determined the internal structure of outside capitals and the structure of current liabilities in the examined forest districts.
Wstępna analiza struktury i zmian zachodzących w obrębie pasywów pozwala na ocenę i ustosunkowanie się do relacji, jakie zachodzą między własnymi i obcymi źródłami finansowania majątku przedsiębiorstwa. Badanie struktury kapitałów w nadleśnictwach ma przede wszystkim na celu określenie stopnia zadłużenia oraz samofinansowania jednostki. Celem niniejszej pracy było określenie struktury kapitału nadleśnictw. Badaniami objęto 26 nadleśnictw Regionalnej Dyrekcji Lasów Państwowych w Poznaniu w latach 1998-2001. W pracy obliczono wskaźniki struktury kapitału i wskaźniki zadłużenia kapitału własnego w poszczególnych latach okresu badawczego oraz ustalono ich wartość średnią. Ponadto określono strukturę wewnętrzną kapitałów obcych oraz wewnętrzną strukturę zobowiązań bieżących w badanym okresie dla poszczególnych nadleśnictw. Na podstawie badań stwierdzono relatywnie niewielkie zróżnicowanie ogólnej struktury kapitałów nadleśnictw. Dominujące znaczenie miały kapitały własne. Stopień zadłużenia nadleśnictw w badanym okresie był stosunkowo niski, przy czym było to przede wszystkim zadłużenie krótkoterminowe (94%). Badania potwierdziły zróżnicowanie struktury wewnętrznej zobowiązań bieżących w badanych nadleśnictwach. Na podstawie przeprowadzonych badań stwierdzono, że polityka nadleśnictw w zakresie kształtowania struktury kapitału ma charakter konserwatywny.

Opis:
nowadays, improving forest management is done by way of amendments to the forest management instructions, silvicultural rules and forest protection instructions. From the point of view of forest management, the most important is the forest management plan, the basic document prepared for a specific object, containing a description and assessment of the state of the forest, as well as the objectives, tasks and ways of forest management. Before each subsequent revision of the forest management guidelines, new instructions are developed in consultation with the public, based on discussions on the proposed changes that are in each case to serve as the best plan for forest management. the forest management plan is vital as it ties together silviculture, conservation, production and non-production purposes as well as social forestry tasks, but only if the primary and operational nature of the objectives considered at the stage of creating the plan are recognized. therefore, the role of forest management in shaping and protecting the environment cannot be overestimated. In this work, we outline the basic principles and rights related to both, forest management under various forms of ownership, as well as detailed guidelines for the content of the forest management plan. We found that the specificity of mountain forests requires the use of different rules and methods. taking into account the exis- ting rich scientific achievements, it is tempting to attempt to develop forest management instructions specifically for mountain forests, whether in the form of a separate chapter or a separate publication. the basic problem with forest management under other forms of ownership (urban, experimental, private forests) is the lack of a detailed legal basis accounting for their specific nature. therefore, appropriate steps should be taken towards intro- ducing appropriate new or supplementary provisions into the forest legislation, which would allow for the development of modern standards. For the state Forests, forest management instructions should be prepared by a team of experts appointed by the Minister of the Environment who will approve the finished document for official use. the forest management plan should include an economic annex focused on the forecast of the expected financial result, inclu- ding costs associated with a deviation from the optimal due to social or protective reasons.

Opis:
Survival trees and forests are popular non-parametric alternatives to parametric and semiparametric survival models. Conditional inference trees (Ctree) form a non-parametric class of regression trees embedding tree-structured regression models into a well-defined theory of conditional inference procedures. The Ctree is applicable in a varietyof regression-related issues, involving nominal, ordinal, numeric, censored, as well as multivariate response variables and arbitrary measurement scales of covariates. Conditional inference forests (Cforest) consitute a survival forest method which combines a large number of Ctrees. The Cforest provides a unified and flexible framework for ensemble learning in the presence of censoring. The random survival forests (RSF) methodology extends the random forests method enabling the approximation of rich classes of functions while maintaining generalisation errors low. In the present study, the Ctree, Cforest and RSF methods are discussed in detail and the performances of the survival forest methods, namely the Cforest and RSF have been compared with a simulation study. The results of the simulation demonstrate that the RSF method with a log-rank score distinction criteria outperforms the Cforest and the RSF with log-rank distinction criteria.

Opis:
Current forest protection related to the economic use of natural resources is compatible with the modern understanding of nature conservation as a whole – protection of ecosystems, biodiversity, natural and anthropogenic processes occurring in nature. It is also consistent with the principles of sustainable development. Forest protection is governed by a number of legal acts. Historical reasons underlay this diversity. The historical background of the emergence of protective forests intertwines with the history of forestry, strongly dependent on the economy of the region. In the Western Europe, forest management was strongly correlated with the development of mining, which needed significant quantities of wood to strengthen underground constructions and the development of a metallurgical industry based on wood as an energy material. Forestry was to ensure uniformity in the supply of wood, which was beginning to be scarce in more densely populated industrial areas. In Poland and other countries with a subsequent development of an economy based on mining industry, forestry was based on the rational use of renewable forest resources, but slightly different reasons for the development of conscious forest management. It can be assumed that the forestry of our cultural and economic zone developed in the estates as a way to obtain additional income. This simplified comparison shows the difference of causes and the similarity of the effect – the development of forest management and with it the development of the idea of protecting forests that perform protective functions. The aim of this study is to show the historical background of the existence of protective forests – a special form of protection of natural resources, resulting today with the Act on Forests and occupying over half of the area of the State Forests in Poland. The paper is a review of the historical sources. We describe the evolution of the reasons for which the forests are protected. It was emphasized that this was taking place in parallel or earlier than the decisions resulting from conservative nature conservation. The article is an attempt to prove that protective forests originate from the fear of insufficient forest resources, lack of certain specific forest types at an early stage of settlement.

Opis:
Mountain forests constitute one of the most diverse ecosystems, not only in Europe but also all over the world. Mountain ranges, which frequently encompass multiple countries, constitute a unique link between various natural areas, which are very often completely different from the historical point, or which are characterized by different use and management types. Although the role of mountain forests is relatively well recognized nowadays, in the distant past, these areas were poorly penetrated, mainly due to the unfavourable climate and natural topography, which discouraged not only from settling down but also from moving around. Despite the fact that mountains had been the object of interest of mining, weaving, and glassmaking industries for hundreds of years, dramatic changes in the stands in these areas were sealed by the industrial revolution in the 18th and 19th centuries. The purpose of this paper is the analysis of forest dieback process in the mountain ranges of Sudetes and Western Carpathians placed in Poland. Stress factors have been divided into three main groups, however, it should be remembered that it is a very simplified division and some factors could be partially found in the anthropogenic, as well as biotic, and even abiotic factor groups. Neither the beginning nor the end of deforestation process was defined precisely in the study, which was deliberate in taking into account constant changes in the ecosystems. Generally, three periods may be distinguished here, regarding the spruce forests dieback process. Typically anthropogenic deforestation, caused by the industrialization of the areas during the industrial revolution and earlier, deforestation in the years 1970–1980 and partially before the year 2000 (Western Carpathians) caused by a set of various stress factors and the latest period, that is, generally understood climate change. The last several years have particularly contributed to the expansion of detailed knowledge about the dependencies and the influence of abiotic, biotic, and anthropogenic factors on the health condition of spruce trees. Although models have already been developed, which describe the course of insect outbreaks, the growth and health condition of spruces, or climate factors, no model has been developed so far that would allow to depict the process of hitherto deforestation, and to enable modelling the forthcoming changes. It seems that the development of such tool, not only from the forest management point of view, would constitute a milestone on the way to precision forestry.
