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.

Opis:: The paper presents an outline of problems associated with dynamic ecosystem stability viewed from the angle of a forest which was completely excluded from productive utilisation. The following notions were distinguished: forest stability, stand stability and managed forest stability. The author's own interpretation of forest development was presented. The model portrays the development of the forest and the role of self−regulation as a negative and positive feedback. The relationship between the effect of self−regulating capabilities and the effect of ecosystem resistance to de−stabilising actions was taken into consideration.

Opis:: The forest development strategy is a hierarchical set of actions specifying the ways to achieve three mutually integrated objectives: principal (strategic), tactical and operational. The principal objectives are formulated in the forest development control process and relate to forests understood as a whole, are long−term and determined by the forest and ecological policy of the state. The tactical objectives are formulated in the forest management regulation process, are medium−term (10 years) and refer to forest estates or forest management units. The operational objectives are formulated in the forest management planning process, are short−term (annual) and relate to economic activities performed in individual stands.

Opis:: The study was accomplished in the Wołów Forest District (SW Poland) and focused on relations between the soil environment characteristics and the incidence of Prunus serotina in different types of forest habitats. The redundancy analysis (RDA) carried out indicates significant effect of the soil moisture contents on the species dispersion. Moreover, it has been demonstrated that black cherry saplings respond to soil fertility and acidity.

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:: The aim of the study was to analyse the changes in abundance and species composition of dung beetles (coprophagous Scarabaeoidea) inhabiting Scots pine stands in various stage of the development. Beetles were collected in baited traps in Człuchów Forest, Pomeranian Lake District (NW Paland). In total we collected 87,596 specimens representing 41 species (tab. 2). The structure of dung beetle communities inhabiting analysed Scots pine stands changes in the course of the forest developmental cycle. Lands adjoining to a forest, clear−cut areas and plantations are inhabited by heliophilous communities of dung beetles, with superdominant species Trypocopris vernalis and dominant species such as Anoplotrupes stercorosus, Aphodius pedellus, Euorodalus coenosus and Chilothorax distinctus (tab. 2, fig. 5a). Thicket stage, pole timber stage, and the mature stand are inhabited by umbrophilous dung beetle communities characteristic for pine stands, with superdominant species Anoplotrupes stercorosus and dominant species Trypocopris vernalis (tab. 2, fig. 5b). At thicket stage the number of dung beetles species is dramatically reduced in comparison to other developmental stages (fig. 3). Moreover, a fundamental change in species composition is observed.

Opis:: The article examines peculiarities of implementing the concept of sustainable development in the forest legislation of Russia. On the basis of analysis of legislative provisions and law enforcement practice the authors substantiate the conclusion that, despite a number of drawbacks of Russian criteria and indicators of sustainable development in the field of forest use, their approval means Russia’s commitment to their observance to assess the level of sustainable development, since they are a mechanism for monitoring of and influence on the system of sustainable management of forests. These criteria and indicators require further development by including social indicators of sustainable development in them, which will allow moving from the strategy for ensuring rational use of forests aimed only at finding a balance between environmental and economic interests to full implementation of the concept of sustainable development in the field of forest use.
W artykule poddano analizie wprowadzanie koncepcji rozwoju zrównoważonego do prawodawstwa odnoszącego się do lasów w Rosji. Na podstawie analizy przepisów prawnych i praktyki egzekwowania prawa autorzy uzasadniają wniosek, według którego pomimo wielu wad rosyjskich kryteriów i wskaźników zrównoważonego rozwoju w zakresie użytkowania lasu, ich zatwierdzenie oznacza zobowiązanie się Rosji do wejścia na drogę zrównoważonego rozwoju, ponieważ są one mechanizmem monitorowania i wpływu na systemu zrównoważonego zarządzania lasami. Te kryteria i wskaźniki wymagają dalszego rozwoju poprzez uwzględnienie w nich społecznych wskaźników zrównoważonego rozwoju, co pozwoli na przejście od strategii na rzecz racjonalnego wykorzystania lasów w celu znalezienia równowagi między interesami środowiskowymi i gospodarczymi a pełnym wdrożeniem koncepcji zrównoważonego rozwoju w dziedzinie użytkowania lasu.

Opis:: Purpose of the work: Mountainous areas, with altitude over 700 m, intense relief and slopes between 16–20%, cover 43% of Greece and they are usually characterized by low population density and long-term unemployment. The Greeks have a dependent connection among environment, economy and society as the history illustrates. Many of Greece’s historic, cultural landscapes and native ecosystems have been degraded or isolated over the years. There is scientific evidence that Greece’s natural/semi-natural forested areas cannot be sustained without watersheds, ridges and other natural corridors that connect its native landscapes and ecosystems. Logging systems are really ancient by using often only mules or horses. The aim of the work is to estimate how harvesting systems should be technologically upgraded improving forest work and social wellness maintaining at the same time ecological sustainability. Approach: The study area is held at Samarina region, a mountainous area of Northern Pindos in Greece. Social data were collected with questionnaires and local visits for better understanding of human resources for forest authorities and other administrative information’s. DTM, Forest Inventory data and other GIS data have been derived by paper maps and previous studies. A registration of road-net and human resources within the protected area of Valia Kyrna and their contribution as factors for the sustainable development was used.The development of a Spatial Decision Support System that can concern all the conditions that are need in order to make an estimation of the optimal way of harvest a stand is really a challenge. Expected results: A GIS program is a powerful decision support tool in order to give the opportunity to the offices of Forestry to choose the optimal way of harvesting a stand and also to realize visually the effect’s of such a kind of work; that is going to be held to the inhabitants and to the tourists of the area. Conclusion: The potential of social and ecological factors is examined as it concerns the promotion of the protected area within sustainable rural development. Advantages of registration in the form of a spatial tool, especially when many types of information participate, are presented.

Opis:: The necessity to combine forest resource management with regional development is a social requirement. The halting of the forestry marginalization trend is the result, among other things, of the lack of strong links between forest management and local communities’ development, as well as the lack of a holistic approach to the space management principles. The paper analyses the causes and possibilities of solving forest, forestry and regional development problems.
