    Opis:
    The paper presents the history of approaches to forest management derived from the idea of forest sustainability, as well as its inspirational role in the formulation of the concept of sustainable development of forests. The promotion of this concept in forestry is the responsibility of forest management planning through the modification of forest management plans and adaptation of the principles of conducting forest management to changing realities. Changes in planning, both in terms of time and space, are necessary especially because of the reconsideration of the range and significance of forest functions. The development of the ‘normal forest’ model and management unit−level methods of forest planning was a key event in the history of forestry in Europe. The development of knowledge, as well as economic, technological and social changes were conducive to the emergence of new theories on the production intensification and to use the economic criteria for determining the rotation age. This also referred to the need to develop an appropriate forest structure to ensure the sustainable use of forest resources. As regards determination of the harvest level, the development of the stand−level method of forest management published by Judeich in 1871 is worth noting. Recent results of the research on forest habitat and productivity have revealed the problem of forest species composition and the importance of forest tending activities. Another group of research achievements cover the new systems of determining the allowable cut taking into account forest maturity and sustainability criteria. In the multiple−use forest model being implemented in Poland, forest utilization is to be treated as a realization of all forest functions expected by society. Accordingly, two functions of forest use can be distinguished − the temporary function aimed to satisfy the current demand for timber, and the strategic function to secure a relatively steady, long−term timber supply, as well as to improve the condition of forest resources. The idea of the modification of the principles of deter− mining the volume of harvest, meeting the set requirements, is a continuation of the above issues. The changes taking place in the conditions of the planning process in forestry over the last decades have caused its continuous extension in terms of range and interdisciplinary areas. The principles of forest use, renewal, tending and protection create a logical and chronological sequence of events showing the complexity of the problems that appear at the stage of planning and in the forest district practice. The current problem at the stage of forest planning is the effect of climate changes on forest ecosystems and possible measures to counteract them. When creating forest management plans, the adaptation activities related to forest management are gaining importance.

    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.

    Opis:
    Nowadays in forestry, we observe an increase in threats that rise the uncertainty and risk of the forest management. This is caused, inter alia, by increasing intensity of forest and environmental damage as well as by the conflict of expectations for the use of forest resources. As a result, there is a problem of achieving the goals of sustainable development and adaptation of the forest ecosystems to new challenges. The aim of the presented study was to assess the regional variety of the need and the urgency of stands conversion. The feature was determined for all stands of the State Forests older than 20 years. Three assessment criteria were selected: (A) silvicultural target (compatibility of the species composition with the planned one), (B) stands stability (resultant from 5 auxiliary sub−indices), and (C) stock level (including 2 auxiliary sub−indices). The majority of stands has consistent species composition (over 60% in total), however only a small fraction of stands was found with a species composition incompatible with the planned one (average 6.34%). Stands with medium stability accounted for about 70%, while those with poor growing stock status make up about 70% of stands under analysis. The regional diversification of the needs for stands reconstruction seems to be strongly correlated with the incompatibility of stand’s species composition with habitat conditions. The largest fraction of stands requiring conversion was observed in Wrocław, Kraków and Katowice regional directorates of the State Forests. This situation may change in the future due to dynamic changes resulting from modifications of the climate and the deterioration of health condition of dominant Scots pine stands in central and north parts of Poland. Private forests were not taken into consideration in this research. It may impact the overall picture in regions of the high share of private forest ownership.

    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.
