Opis:
In Poland, the stormy discussion on the future of the Białowieża Forest has been ongoing already for a long time. The disputes are mostly focused on seeking answers to two questions: how to protect these unique forest ecosystems and whether forest management threatens their naturalness. The discussion has grown stronger after the recent, enormous outbreak of Ips typographus in the Forest. The Białowieża Forest has been managed for years with no negative effect. However, antagonists of foresters blame forest management for degradation of the Forest’s ecosystems, which is caused by favoring the economic value of timber expected to be harvested in keeping with the management plans of 3 forest districts located in the Białowieża Forest. At any rate, such assumption, has nothing to do with reality. During this discussion the idea to extend the national park for all the Białowieża Forest revived. In this paper, we reviewed the economic, social and ecological dimensions which should be taken into consideration before making a decision on extending the Białowieża National Park. It should be underlined that the Park’s area is already under the strict protection; furthermore, 2/3 of the area of neighboring managed forests are under legal protection (the nature reserves, NATURA 2000, the so-called reference forests, etc.). All things considered, we cannot find any reasonable purpose (ecological, financial or social) for expanding the Park’s area from 10 500 ha (present status) to 62 500 ha (after extension). Also, we are convinced that sustainable forest management conducted in managed parts of the Białowieża Forest, which comprises the fulfillment of all forest functions and services, should not be perceived as a threat to naturalness of the Forest’s ecosystems.

Opis:
Bivariate distribution is an effective approach to spatial structure analysis. Combined with two of the three structure parameters (uniform angle index (W), dominance (U) and mingling (M)), the structural bivariate characteristics of five different Pinus massoniana forests were explored in this study. Our objective was to provide a theoretical direction for structure-based and detailed management in P. massoniana forests. The bivariate traits showed that mixed artificial or secondary forests predominated by P. massoniana trees do not typically achieve the highest mingling level. Trees under extreme mingling conditions were rare and typically comprised of non-dominant species instead of dominant ones in P. massoniana forests; these trees were generally overtopped and randomly distributed. Management implications can be extracted comparing the bivariate traits between all species and dominant species. The original community structure, development stage, and mixed-tree species number affect the univariate M and, furthermore, the two bivariate U-M and W-M distributions in mixed forests. Forest type has little effect on all-species W-U traits compared to those of the dominant species. U-M traits should be adjusted first if the random frequency values are highest in W-U and W-M bivariate distribution, and it is necessary to determine whether these two bivariate traits shade the W univariate. Adjustments made based on bivariate distribution can reveal poor frequency combinations for foresters to target; this allows the simultaneous adjustment of dual aspects of forest structure based on one bivariate index. Our results show that bivariate distribution may provide very useful information for the management of P. massoniana and other forests.

Opis:
Modern multifunctional forest management needs indicators showing the state of forest environment. Commonly used solution is monitoring of the abundance of species with specific environmental requirements. This paper analyses the possibility of use of the biggest European woodpecker (Dryocopus martius) as forest management quality indicator. The black woodpecker resides in all types of forest sites. The species prefers big thick trees as a nest trees, its cavities were mainly made in birches Betula sp. in Western and Southern Europe, Scots pines Pinus sylvestris in Middle and Eastern Europe and aspens Populus tremula in Northern Europe. The black woodpecker, excavating large−sized breeding cavities, is defined as a key species due to the creation of breeding sites for large secondary cavity−nesters. Because of the breeding requirements, black woodpecker can also be treated as an umbrella species for organisms associated with old trees. The way of feeding of that species shows a strong connection with the availability of dead wood. The black woodpecker is a sedentary species, which means that it is highly depended on the structure of the forest and quickly responds to changes caused by forest management. Because of the habitat requirements and relationships with other species, as well as the wide geographical range, it is a good indicator species for multifunctional suitable forest management. It can also act as a keystone species for secondary cavity nesters and umbrella species for organisms associated with old, dying trees.

Opis:
Forest management profitability can be raised by increasing stand productivity, which comprises improving wood yields and quality. The United States of America provides a good example of intensive management techniques applied on large scale to substantially increase forest productivity. Experiences of the U.S. South's forestry sector provide evidence that research−based intensive growth technologies are the key factor in ensuring adequate wood supplies and in effectively promoting sustainable management of the region's forest resource. Management treatments such as applications of fertilizers and herbicides have yielded lard productivity increases to date. Genetic improvement also has yielded large productivity increases along with improving stem straightness, wood properties, and disease resistance. Modern timber growth technologies already make possible doubling or even tripling current pine growth rates, while research progress indicates that current growth technologies can be improved even further.

Opis:
The aim of the paper is to assess the benefits to the owners of private forests from joining forest associations, as well as to present the respective legal regulations in force in Poland and selected European Union countries. The examples of the countries with years−long experience (Germany, Austria, Finland and others) in forming associations of private owners show that the participation of private owners in such associations can be significantly advantageous to them. Collective management of forest resources can first and foremost serve the rational management of private forests and the seeking of measures to decrease business costs with a simultaneous increase revenues from timber sales. Poland's accession to the European Union should result in an increase of benefits to private owners due to their membership in various forms of forest associations. This mainly concerns the opportunity to obtain funds from the UE budget. The process of forming forest associations by the owners of private forests should be supported particularly by state administration and territorial units of local government. The Polish legal system does not provide too many legal forms of association to private forest owners, just two: land communities or unions assuming the form of associations. The German legal system, offering private forest owners as many as five forms of association, is more developed in this respect.

Opis:
The State Forests, National Forest Holding, is increasingly burdened with the costs of nature protection, recreational development and certification. As a consequence, there is an increase in costs and limitations in forest management. The emphasis is also on different social and environmental functions, and as a result, income from the sale of wood becomes smaller. The aim of the study is to verify the concept of an analysis of the past economy in conditions of variable costs of forest administration and production (period of 10 years), which is the basis of looking for solutions to improve the efficiency of financial management at the level of the forest district. The case study was based on the forest district located in Regional Directorate of the State Forests in Krakow (southern Poland). The current forest management plan is valid for 2014−2023 period. The analysis of the past economy covers the years 2005−2014, that was nine years of validity of the previous plan of the forest management plan and the first year of validity of the current plan. Issues discussed include: cost and revenue analysis, timber sales, forest management, employment and wages, side−line activities, infrastructure management, maintenance of supervision over forests of other forms of ownership or cash flows of forest funds. Described forest district is an administrative unit with a small forest area and a large fragmentation of forest complexes. The level of the deficit was not significant, and in recent years has been decreasing. In the period under analysis, the increase in costs was proportional to the increase in revenues. The share of administrative activity costs remained at a similar level. Administrative expenses were higher than the costs of core operations. The low level of primary activity costs resulted mainly from low investment outlays. Investments in road infrastructure may be connected with increasing the attractiveness of the entity in the eyes of wood buyers and, consequently, an increase in the prices of wood raw material. In the period under analysis, the forest district undertook activities aimed at optimizing the employment. These activities led to a significant reduction in the number of employees.

Opis:
Planned forest management is carried out based on the forest management planning (PUL) operations prepared for a 10−year economic period. The economic expertise may omit a detailed organizational analysis of the company, as well as indications regarding the search for strategic solutions. The following study aims to present a method for analysing the economic consequences of forest management activities by the forest district in the context of selected forest districts. A new element, in relation to the content of the forest management plan, is the inclusion in the economic expertise (EEN) of the economic analysis of the forest district in the context of other forest districts (benchmarking). Due to the fact that economic data are sensitive data, information about the name of the forest district under analysis and comparator districts are not given in the publication. The most important management and economic indicators for the forest district should be presented against the background of the results of similar and extreme units in the Regional Directorate of the State Forests (RDSF) in the relation to the district inspected. It was assumed that the forest district, for which EEN will be developed, will be compared with the four forest districts of RDSF. Data and the scope of the EEN must provide the possibility of its updating in any period of validity of the PUL, especially in situations when phenomena occur that fundamentally change the planned scope, time, place and size of economic tasks. The forest district, analysed in the context of comparison units, should pay special attention to the proportions between the costs of the core activity, and thus the main part of the activity, and the administrative costs. Analysing the economic efficiency of forest management, apart from the quantitative dimension of obtaining timber, it is necessary to pay attention to the value dimension. Costs incurred by the superintendences for employment of employees constitute the main group of administrative costs. It should be incur in mind that the structure of costs and revenues in the superintendence depends largely on natural conditions. Irrespective of the specific character of the forest district, the main revenue group is revenue from the sales title acquired in the forest district. In turn, a significant group of costs are employment costs of employees and other administrative costs. Revenues do not depend only on the quantity of timber harvested and sold, but also on its quality and species. Administrative costs should be limited by adjusting them to tasks in the field of forest management, sales of timber and local specificity of the unit. The costs of forest management depend mainly on the conditions under which forest management is carried out.

Opis:
The forest management plan is the basic document on which the functioning of the forest district in a ten−years−long perspective is based. To maximize the usage, the economic expertise of the forest district administration (EEN) utilises in the large part of the analyses data available in the Information System of the State Forests, which can be obtained at the forest district level. The EEN consists of three basic parts: the general characteristics of the forest district, analysis of the past economy and a prognostic analysis. To preserve the operational character of the information, the most important parameters set for the forest district should be compared with the values for selected forest districts from regional directorates of the State Forests. The quality of the prognostic part of EEN depends primarily on the correctness of the adopted indicators and set values in the part analysing the effects of the past economy. The significance of this part of the EEN means that it should contain the most important elements related to plannable economic events and the related economic consequences. The introductory part of the EEN should start with presenting the background, the period and the principles of forest district functioning. One should remember that this document is not only prepared for the forest environment, but also for the people not related to forestry. In the main part of the expertise the natural, organizational and economic conditions of the forest management implementation in the given forest district are presented in a synthetic form. The economic expertise of the forest district is an expert study. Its primary goal is to determine the economic consequences of the implementation of the forest management plan prepared based on a synthetic assessment of the results of the past economy, taking into account the current conditions in the medium−term planning. The economic expertise for the forest management plan may be an important tool in improving the functioning of forest district and planning at various levels of management. The data contained there also allow to follow the dynamics of economic phenomena in the organizational units of the State Forests.

Forest management is carried out based on the economic calculation, taking into account the principles of forest sustainability and protection. For a short period, an attempt to predict the unit’s economic situation on the basis of the analysis of the time series with a trend can be made. Appropriate exponential equalization methods were selected. When forecasting fixed costs in the new economic period, six methods were used (from the last year, from the last three years, Brown simple exponential smoothing model, Holt linear model, Winters model in the additive or multiplicative version) as well as the average value of all forecasts applied was calculated. To evaluate the tested models, among others, mean absolute error, root mean squared error and the predictability of the forecast were assessed. All analyses were performed using the MS EXCEL Solver add−in. Forest districts for which forecasts were made are located in the Regional Directorate of the State Forests in Krakow (A) and Białystok (B). Source data for forecasts came from the State Forests IT System and covered the years 2005−2014. The aim of the research was to evaluate the possibility of using the forecasted economic parameters in forest management planning estimated by various models and techniques of empirical verification. The study attempts to answer the question whether there is an econometric method that allows accurate forecasting of the economic situation of the forest district in the context of the realization of the tasks listed in the forest management plan. Relatively high accuracy of forecasts was achieved using the Holt linear model. Brown model, due to its methodological assumptions, resulted in a reduction in forecast results compared to other forecasting methods and expert knowledge. The method based on calculating the average value from many previously made forecasts gave very good results, which is also reflected in literature. Regardless of the group of costs analyzed, both fixed and unit variables, the lowest values of assessment of the compatibility of forecast were obtained by making the forecast based on the result from the last three years.

Opis:
The approach to forest management has changed many times over the time. Forest receives increasingly a lesser extent as wood and wild game supplier. Social and protective functions of the forest have begun to play more and more essential role. Change in the perception of the forest functions entails the questions about the economic consequences of the forest management in an era of changing priorities. This paper aims to compare approaches to the economic consequences of actions undertaken in the forestry in different periods. The evolution of the approach to the economic analysis can be traced. Analysis of historical publications allows to observe the changes, starting from 1820, when no special attention to the uniformity of drawing income from the forest was paid, through the interwar period, when attempts were made to maximize the profitability of forestry and through the World War II, when no analysis of economic rationality was taken, to the current situation, when more and more attention is paid to the economic consequence of changes in forest management priorities. Presented issues should be a contribution to the discussion on economic issues associated with conducting forest management especially in the context of the tasks included in the forest management plan. It must be noted that, despite the provisions in the instructions for the analysis of forest economic conditions, they often were not reflected in the management plans. Studies aimed at awareness raising and, consequently, the development of the synthetic parameters of an objective description and comparison of the economic conditions of forestry functioning both within the forest district and larger units seem to be necessary.

Opis:
The role of the rodents in forest regeneration includes both negative (seed and seedlings consumption) and positive (seed dispersal) aspects. The objective of this paper is to review the knowledge of this dual effect of the rodents on forest regeneration after disturbance, particularly in temperate managed forest stands. Many studies have demonstrated that consumption of seeds and seedlings by rodents can substantially inhibit regeneration of forest stands after disturbance. Small mammal predation on oak, pine and European beech seeds and seedlings contributes to reduced forest regeneration after tree harvest and natural disturbances such as fires. On the other hand, some rodent species may promote seed dispersal towards deforested areas. Moreover, they frequently prefer nesting and caching of acorns near structures providing shelter. Such structures are abundant in disturbed areas and appear to promote higher survival of cached seeds. Furthermore, there are certain techniques of seed and seedling protection against small mammals, e.g., planting seeds in the soil, using polyethylene tubes to raise seedlings, or providing alternative food for rodents. The positive impact of the rodents can be enhanced and negative minimized through proper management, such as providing appropriate microhabitats for seed caching, or maintaining continuity of canopy cover/forest stands.

Opis:
Knowledge of the vegetation and the monitoring of its changes in preserved areas is an essential part of effective conservation policy and management. The aim of this study was to assess the effectiveness of traditional methods of conservation of silver fir forests. The study analyses the changes in the structure and species composition of a temperate forest excluded from the commercial silvicultural management for 50 years, and since then protected as a nature reserve. The study is based on a comparative analysis of phytosociological reléves made on permanent plots in 1961, 1982, 1994 and 2011. PCA and ecological indicator values were analyzed, as well as characteristic species based on an indicator value (IndVal) index. Results revealed significant and dynamic changes in the forest structure and composition. The mixed coniferous-broadleaved forest with Abies alba and diverse ground flora, considered in the 1960s as valuable and worthy of conservation, was found to have been anthropogenically transformed and unstable. Significant reduction in the human impact was followed by spontaneous regeneration of oak–hornbeam forest. However, the directional process of changes in vegetation was modified by such silvicultural treatments as selective cutting of trees and gap creation, all intended for silver fir maintenance. The results show that Carpinus betulus effectively outcompeted Pinus sylvestris, Picea abies, Quercus robur and A. alba. Changes in the forest overstory and understory caused temporal changes in the habitat conditions reflected in changes in the ground vegetation composition. The proportion of light-demanding and oligotrophic species significantly decreased, while the contribution of species with a wide ecological amplitude, i.e. more shade-tolerant and nutrient-demanding – increased. The share of A. alba was reduced. Species defined in this study as most valuable, should be actively protected, or selection of conservation targets should be re-evaluated.

The article discusses the project of good practices for the manager of the urban protection forest, i.e. a model and universal set of protection and management guidelines necessary for the proper shaping of forests in a city. The set of guidelines proposed as the Chart of the Urban Protection Forests includes: shaping multigenerational tree stands; a gradual and spread over time succession of tree generations; maintaining old-growth forests and biocenotic trees in the largest possible number, on the largest available area; the continuous presence of older and middle-aged trees in every part of the forest; resignation from clear-cutting in renewing of tree-stands; promoting and making full use of natural regeneration of tree-stands; passive protection of waterside and wetland forests; active protection of natural diversity as needed; shaping and reconstruction of tree-stands, especially in the habitats of pine and mixed forests; using sanitary pruning when necessary to maintain the durability of tree-stands; complete abandonment of plowing in forest regeneration; zoning; designation of restricted animal sanctuaries; participation and co-responsibility of the society. The introduction of the proposals contained in the Chart of the Urban Protection Forests, at least in part of the protection forests in the cities, could certainly contribute to increasing social acceptance for forest management and avoiding unnecessary conflicts around urban and suburban forests.

Opis:
The controversy between naturalists and foresters on the management of the Białowieża Forest is one of numerous disputes in conservation biology. Cause of the dispute is a difference in stand-point on the purpose of nature conservation. Biocentrists (Soulé 1985) argue that the only goal should be to preserve natural processes as well as endangered ecosystems and species. Anthropocentrists on the other hand (Kareiva, Marvier 2012) support conservation as a need of mankind, i.e. the sustainable support of ecosystem services with the protection of species and ecosystems simply being a side effect. Another important factor in the dispute is the management of bark beetle mass outbreaks. Foresters try to control by removing the infested trees, but naturalists protest against this practice. However, in 2013 the European Commission clearly presented its statement in this regard (EU Guidelines on Wilderness in Natura 2000) and thus the dispute has only shown that none of the debating parties are familiar with the EU guidelines. According to the author, the more serious problem of messy organization of the Białowieża Forest conservation is rarely raised in the dispute. Multiple protected areas were established in the forest based on six different law forms for nature conservation and two forms of international origin. Such surplus of forms and areas leads to chaos and hinders the management of this valuable area.
