    new method of regulation of selection or near−selection forest type development
    Opis:
    In uneven−aged forests, age does not apply to the whole stand but to individual trees. Therefore age of individual trees is rather represented by their thickness, and dbh distribution types become the measure of their age. The distinguished dbh distribution types show individual uneven−aged forest development phases: type A – optimum phase, type B – initial phase, type C – future phase and type D – ageing phase. In the optimum uneven−aged forest development phase, 'prescribed cut according to silviculture needs' should be similar or equal to volume increment. In the initial development phase, such 'prescribed cut' should represent 60−80% of current volume increment, while in the future forest development phase, it should equal the current volume increment or exceed it by 20%. In the ageing forest development phase, 'prescribed cut according to silviculture needs' should be higher than the current volume increment by 10−30%. Selection−type forest management should be a model one for uneven−aged forests. Selection−type forests are close to the natural state and constitute a stable forest ecosystem with high resistance to biotic and abiotic factors and by reducing and dispersing the management risk they better fulfil their multiple functions.

    Opis:
    This paper deals with the author's research results on the current situation and future prospects concerning the value of forestry in rural development presented in various reports and papers including columns of Sylwan. Forestry forms a substantial part of the rural economy. Wood ad other forest products and their processing secure a number of jobs in rural areas increasing socio−economic stability and development. Apart from the economic aspects, forestry has a lot of non−market values. It is necessary to analyse potential economic and social benefits of forestry to rural areas and their development of both market and nonmarket values and to include those benefits in rural conceptions.

    Opis:
    Properly conducted forest management is one of the essential conditions for the forests protection. The state of the natural element in Poland is affected, in various scale, by a number of factors, including those causing the formation of unfavorable changes in the forests condition. In this study, we would like to focus on a group of anthropogenic factors, whose negative impact, in our opinion, can be limited by the well−managed green public procurement policy. The aim of this study is to show the legal possibilities offered by the new EC directives on public procurement in relation to the protection of legal good which are forests, in order to stimulate the national legislator to proper implementation of these provisions into national legal order. Contents provided in this study are based on analysis of the provisions of normative acts and views expressed in the science of law on the ground of considered issues. At the same time, the analysis conducted in such a way allowed us to obtain the following results and conclusions. First of all, the environment protection, including forests, is becoming an increasingly important part of any modern economic policy of the state. Emphasizing the achievement of environment protection aims, including forests, through public procurement, requires the activity of the state, in particular the activation of particular groups of public entities. Only a coherent and integrated policy for public procurement in the state, can give the desired results. From our point of view, the President of the Public Procurement Office has a crucial role in the creation of public procurement environmental policy. At the same time, with the existence of legislation enabling the use of public procurement to protect the environment, including forests, the entities granting public procurement often do not benefit from these opportunities. In our opinion, there is some kind of mental barrier of people responsible for public procurement procedures that focus on the current cost of purchase, not interested in further operating costs and any maintenance and repair. It is therefore advisable to add more attention and care in the preparation of specification of terms of procurement, in order to take into account possible criteria relating not only to the current cost of purchasing, but also including subsequent operating costs. To this the new legislation contained in Directive 2014/24 EC and Directive 2014/25 EC should significantly contribute.

    Opis:
    The objective of this paper is to review the criteria and indicators currently used for the assessment of forest management and to compare them with the criteria and indicators recommended in the economic literature. There are discrepancies between the types of indicators proposed in the economic literature and those applied in practice, which often result from the adoption of different concepts of sustainability and/or definitions of the welfare. It appears advisable to supplement the set of natural criteria and indicators with economic ones, so that the ability to self−finance the forest economy should not be forfeited.

    Opis:
    The paper presents the ideas of sustainable development with regard to the specific forest issues and management of its resources. We consider two main directions of forest use, which have the greatest impact on the condition of forest environment, i.e. logging and recreational use of the forest. This confrontation shows how effective the instruments of sustainable development are in collision with, on the one hand, the pragmatic−economic issue of profitability and a specific profit from logging, and, on the other hand, with the autotelic tourist exploration of the forest. The aim of the paper was to discuss selected aspects of sustainable forest use with regard to the sustainable development program and to identify problems, which modern forest management (forest utilisation) faces as a result of society’s expectations and the possibilities of today’s forestry in Poland. The example of Poland shows that there is a full understanding of the need to preserve the forests in the landscape, which was reflected in the form of legal acts and adopted international regulations for sustainable forest management (most forests in Poland have PEFC and FSC certificates). However, considering forest use as one of the main branches of forest management, there is still a large deficit of pro−ecological logging technologies in Poland, especially from difficult mountain areas (about 150 cableways missing), which is largely due to economic factor. The other problem of sustainable forest use in Poland is still low social awareness of the consequences of negative human impact on the forest ecosystem, which is manifested, i.e. littering in forests. Garbage is left both during leisure in forest as well as brought in larger quantities creating so−called wild dumping sites frequently containing also hazardous waste. Another problem of contemporary forest use is the maintenance of durability of forest ecosystems in recreational and tourist areas, especially protected areas, and above all in national parks, most of which in Poland have a forest character. The scale of threat to forest sustainability is incomparably higher here than in economic forests, which results from the large number of visitors in the national parks.
