Opis:
The economic development of the country is very much dependent on the development of the transport infrastructure, which is one of the main priorities of the state policy included in the planning and development documents. Ensuring a efficiently functioning transport system, primarily the network of roads, involves the need to improve the technical characteristics of existing roads or to build new sections. With the linear nature of road investments, we deal with interference in significant areas that have direct and indirect effects. The aim of the study was to analyze the impact of investments realized for different categories of public roads on the area of land needed to be excluded from forest production. The structure and area of the land as well as the number of forest superintendents transferred areas were also analyzed. The study was conducted for forest areas managed by the State Forests National Forest Holding (SF NFH). Data on the area of the transferred forest land was obtained from SF NFH units and the General Directorate of National Roads and Motorways (GDDKiA). In the years 2012−2015, SF NFH units transferred the land into the management of GDDKiA 203 times with the total area of 617 ha. In the same period, the transfer of the land ownership to local government for voivodship, county and municipal roads took place in 388 cases and covered 556.6 ha. Since 2003 (i.e when special act on road investments came into force), the area of the transferred land amounted to 282.7 ha in Toruń, 78.6 ha in Gdańsk and 558.4 ha in Poznań regional directorates of the State Forests. There was a decrease in the area of the transferred lands depending on the category of public roads, while the highest number of events for municipal roads was observed. There is a great variability in the time, number and area of property transferred to public roads.

Functional Forest Areas
Regional operational programs
Opis:
In the era of sustainable and multifunctional forestry, special efforts should be made to designate areas having the status of (multi)functional forest areas (MFA) and to include them in a special development plans. Their operational goals should be: to increase the acreage, to prevent further fragmentation and to preserve the spatial communication between them. Only such an approach will ensure the relative stability of ecosystems and their protection against anthropogenic degradation. Determining the MFA boundaries would certainly facilitate their space management as well as planning and furnishing activities. People responsible for given spatial units would also be able to determine parities of activities and develop optimal solutions in terms of land development, including the socio−economic development of the region. The concept of MFA delimitation and strengthening is consistent with the EU sustainable development strategy, whose provisions refer to the creation of large−scale natural functional areas. The paper objectives was to discuss the legal status of spatial planning in relation to forests and to propose MFA distinguishing and developing regional operational programs for them. It is urgent and necessary to consider the authorities responsible for forest management (relevant units of the State Forests) as authorized to comment on drafts of conditions and directions of spatial development of municipalities or local and regional spatial development plans. It may improve the effectiveness of spatial planning as one of the instruments for shaping forest resources and forest space in accordance with the principles of permanently sustainable forest management. In the study of conditions and directions of spatial development of the commune, the description of the actual state of the forest space as well as the directions and principles of its shaping should be carried out in a specific standard, in consultation with all units responsible for forest management. Distinguishing Forest Functional Areas may impact the optimization of the costs of forest management and nature protection, because after assigning dominant functions to the distinguished areas, directing financial resources to defined functioning goals will be easier both at the planning stage and during implementation. Verification of the results obtained will also be easier and more transparent. An equally important effect will be to indicate potential conflicts between different expectations from forest management. The characteristics of functional forest areas together with recommendations and suggestions for furnishing works should be provided by Regional Operational Programs, including in their content the assumptions of the region’s spatial development policy, valorization of the forest and assessment of its stability, assumptions for activities related to nature protection and water management, characteristics of climate conditions, optimization of the road network, fire protection, tourist development and forest education, characteristics of the state of forest resources and forecasts of the development of wood resources. An excellent source of information for that purpose is the Forest Data Bank.

This study uses quantitative forest surveys, interviews, discussions, and descriptions of the historical context of public participation in forest management including a detailed assessment of field conditions. The findings of a forest resources inventory show that (1) from the three sampled areas, Doi Laung Wildlife Sanctuary has highest richness, followed by village #16 and #14, and (2) Huaikhon #16 implied the process of framework to maintain a healthy condition and response to community needs with collective management. The conceptual model assessment that links key group indicators and drivers is presented based on previously developed assessment models. The framework focuses on the best way to provide forest management, forest fire prevention, and firefighting as well as monitoring of Check-dam construction and other activities that support the recovery of the forest community. This paper demonstrates the general of an environmental assessment framework to applying organize environmental information to facilitate policy decision making for the sustainable development.

Opis:
The change in the use of agricultural and forestry land for other purposes is the natural process of rural areas urbanisation. In the municipalities located nearby large cities, this transformation is inevitable and indeed desirable, while in the municipalities located close to the protected areas, it is a symptom of negative processes, especially from an environmental perspective. Moreover, such transformations have many other economic and social consequences which are worth paying special attention to. This paper is an attempt to determine the level of negative changes introduced in the planning documents in municipalities located within the borders of National Parks. The indicator analysis based on the statistical data of local date bank [BDL] in the fields of local government and spatial planning was conducted. The analysis enabled to present the differences between municipalities with very high natural values in terms of decreasing the area of agricultural and forestry landscape. Furthermore, to elaborate the typology of the studied administrative units the obtained results were verified by comparing them with recommended percentage share of forest and agricultural lands which potentially guarantee good conditions for the development of tourism in rural municipalities.

Opis:
In the face of growing urbanised areas, the presence of forests and their appropriate shaping is a key challenge for contemporary urban planning. The importance of forests is largely identified with natural, economic and social functions in non-urban areas; however, forests are of vital value in urbanised areas. This article explores young Polish urbanites’ awareness of the role forests play, and submits diagnoses of the forests multidimensional benefits and their functions in Poland’s urban areas. Moreover, the research is based on the premise that the management of urban forests must ultimately lead to the satisfying of social needs. Based on empirical research, the perceptions of the value of urban forests as assessed by young people (students) in the Śląskie Voivodeship are presented, leading to the authors’ postulation that urban forests are underestimated resources. Furthermore, the study suggests that young Poles do not recognise the multi-beneficial aspects of urban forests; and the authors indicate feasible directions for local policy to achieve sustainable development. The final statements argue that in the face of serious threats to the functioning of Earth’s ecosystem, a campaign for the presence of forests and green spaces in cities is necessary.
W obliczu rosnącej powierzchni terenów zurbanizowanych obecność lasów miejskich i ich odpowiednie kształtowanie jest jednym z kluczowych wyzwań dla współczesnej urbanistyki. Znaczenie lasów utożsamiane jest głównie z funkcjami przyrodniczymi, ekonomicznymi, czy społecznymi na terenach pozamiejskich. Jednocześnie tereny leśne niosą istotną wartość na terenach zurbanizowanych. W wielu krajach obserwujemy rosnącą świadomość znaczenia lasów dla zdrowia fizycznego i psychicznego mieszkańców oraz prawidłowego kształtowania się relacji społecznych. Sąsiedztwo lasów pozytywnie wpływa na jakość życia mieszkańców miast. Interesujące poznawczo jest na ile mieszkańcy miast w Polsce mają świadomość roli lasów w miastach oraz w jaki sposób z nich korzystają. W artykule dokonano diagnozy wielowymiarowych korzyści funkcji terenów leśnych na obszarach miejskich. W oparciu o badania empiryczne przedstawiono percepcję wartości lasów miejskich w ocenie młodego pokolenia województwa śląskiego (studenci). Na podstawie przeprowadzonej analizy roli lasów autorzy zaprezentowali kierunki wsparcia polityki lokalnej ukierunkowanej na zrównoważony rozwój. Zdaniem autorów, w obliczu poważnych zagrożeń dla funkcjonowania ziemskiego ekosystemu niezbędna jest kampania na rzecz obecności lasów i drzew w naszych miastach.

Opis:
Extension of the forest area in Ukraine is one of the indicators confirming achievement of the goals of sustainable development. Therefore, the issue of protection, restoration and rational use of forest ecosystems is rather actual. The process of self- afforestation taking place on agricultural land, which are not used according to their intention because of their investment unattractiveness, due to lack of funds or other reasons, and thus, they are self-sown with forest plants, is one of the ways of the forest- covered area extension in Ukraine. There is no reliable information on the number of land plots with self-sown forests on agricultural land. Therefore, it is expedient to make inventory of them by using the tools of satellite remote sensing and field surveys. The author of the work suggests a conceptual model of planning the use of agricultural land with self-sown forests on the base of the inventory data. To make the best-possible decisions on the use of the land plots with self-sown forests, at the local level it is important to determine the rational direction of the self-sown forest use in the process of spatial planning on the base of the data of analysis of the soil and plant cover layer quality. Therefore, it is recommended to make zoning of the land by the kinds of land use (agricultural, forestry, recreational, nature protection). Basing on the zoning data and considering the potential ecosystem benefits from forests, it is necessary to develop measures on the self-sown forest use and protection.

Opis:
The paper presents the assessment of possible impact of climate change on forest ecosystems in Poland and its consequences in the forest management planning. Scenarios of climate change in the twenty first century do not allow unambiguous determination of the rate and direction of these changes. However, it is believed that climate change could have negative economic con− sequences, which directly or indirectly will affect the deterioration of the environment. Analysis of the possible forms of the impact of climate change on forest ecosystems is particularly relevant in terms of growth conditions. The most noticeable consequences of the changes will concern the threat to the stability of forest stands resulting from the increase in the intensity of trees dieback caused by different factors. The phenomenon results, among others, from: the occurrence of new threats from biotic factors, including caused by secondary pests and the occurrence of alien species of flora and fauna, the severity of the impact of abiotic factors and the deterioration of health (especially of conifers). The increase in the intensity of the evolution of trees is directly related to the size of the cuts contingent and will lead to a blurring of the boundary between thinning and health−cutting. It is expected that the planned size of the cuts will be implemented mainly in the thinning and accidental cuts. This requires the modification of the perception of the rela− tionship of each category cuts. We propose the order and urgency in the planning of forest use. May be supposed that the role of the clearcutting system will be limited, with the exception of some forest complexes of predominantly productive functions, dominated by poor coniferous habitats. It is recommended to use the natural regeneration in the forest management. Lack of clear boundary between thinning and final cutting will require flexibility in the accounting for the total size of cuts. The consequences of climate change will probably occur in the long term perspective. It can therefore be assumed that reasonably forest management can help to reduce their negative effects. This requires pre−emptive decisions in forest management planning and verification for silviculture, production and protection targets, and their consistent implemen− tation.

This paper addresses problems associated with the silvicultural planning in the Norway spruce mire forests (Sphagno girgensohnii−Piceetum Polak. 1962) that are characterized by an uneven−aged structure and a high degree of irregularity at small scale. Based on detailed inventory using 30 permanent circular sample plots in two control units located in the Augustów Forest (NE Poland), the BDq method was employed for determining future silvicultural activities of the current forest management cycle. The equilibrium models are based on diameter distributions and have the following parameters, depending on site conditions: B=28 m²/ha; q−factor=1.32 and D=51 cm in the case of poorer forest site type (S.−P. typicum) and 55 cm more fertile one (S.−P. thelypteridetosum).

Opis:
Forest managers conducting sustainable forest management are guided by the principles of sustainable use of natural resources, which involve the need for long and short-term planning in organizational units of the State Forests. Plans often differ from reality by the time individual treatments and cuts are to be performed. For economic reasons, it is important to optimize harvest planning, not only focusing on the volume of timber to be harvested, but also the price differences of individual tree species and sort types of wood. The purpose of this study was to present methods evaluating standing timber and to assess their usefulness in optimizing the harvest volume using linear programming. Stands designated to be cut were evaluated using transaction value methods, i.e. “the stumpage value method” M1, the “con- sumption value” method M2, as well as the net present value (NPV) method M3. The research material was obtained from the State Forests Information System (SILP) for the Marcule Forest District covering the years 2014–2018. The stand values were determined at the beginning and end of the 10-year planning period. We observed that the stand value (standing timber) differed significantly between method M2 as compared to method M1. The value of stands determined by method M3, on the other hand, decreased as the discount rate increased. In the process of optimizing the selection of stands for felling, economic criteria should also be taken into account and this is a direct measure of obtainable standing timber in terms of the cutting possibility in the given planning period. In stands where one species dominates, a simplified method of determining the value (M1) can be used, whereas in stands with significant species diversity, method M2 provides a significantly more accurate value for the cutting timber. Howe- ver, if harvest volume optimization using linear programming methods is to take longer time periods into account, e.g. 30 years (three 10-year economic planning periods), the most reasonable method for determining the value of stands is the net present value method M3.
