Opis:
The aim of the work is to present (i) the economic issues included in the forest management plans and (ii) the methodical bases of an ex post economic expertise, which may be carried out in order to evaluate the previous economic period, and should be a part of the economic annex to the forest management plan. Such expertise allows to formulate postulates and objectives to achieve in the near future, which are important for the forestry economics. The transformation in Poland occurred when the third revision of the forest management plans and instruction of the 1980 and 1994 were applied and caused significant changes in the Polish forestry. As a result, the concept of sustainable development of forestry appeared and the indicators and criteria for sustainable forest development were elaborated. However, they concerned mainly natural and social aspects, while the economic aspect was marginalized. Gradually, foresters began to appreciate the role of the economic analysis. The first versions of such expertise was already elaborated for the individual forest districts. The experience gained will certainly contribute to their dissemination and appreciation of included analysis and forecasts. The economic annexes should include information on value of the forest with an indication of the value of land and the stands themselves. The knowledge on the value of the forest, except for registration, is also required in determining changes as a result of business (in the income statement). The valuation of timber resources is also necessary in the evaluation of the effectiveness of economic projects in forestry affecting the changes in their value. In practice, the valuation of the forest is also essential in case of a change in the ownership or land use status. This usually applies to the sale, purchase, conversion or liquidation of the co−ownership, and also compensation for expropriation because of the road or residential construction. Furthermore, determination of the forest value is necessary in assessing the share of agriculture in national income. This applies particularly to the integrated economic and environmental national accounts in forestry, conducted in some European Union countries. The presented methodology of economic expertise points out the possibility of application the formula that introduces standardization of analysis of economy in the last economic period. It is also the contribution to the discussion on the elaboration of a single, synthetic parameter, which may influence on objectivity of economic conditions of the functioning of the forest holding.

Opis:
The rate of change in the cost of logged timber and prices of raw timber during the period, 2001-2009, was examined for the Regional Directorate of the State Forests in Zielona Góra. A logarithmic evaluation of average rate of change indicated that the rate of increase in timber harvest costs was higher than the rate of increase in the average price of raw timber and likewise the price of most log grades. The average increase in raw timber value was 2.51% annually. The price of low-diameter raw timber (slash) increased 8.61%, and the price of large-diameter timber increased 1.94% annually, while the price of large coniferous segments increased 1.75% and broadleaf segments increased 2.98% annually. At the same time, the timber logging costs increased more than the timber price, to 4.17%, or 4.19% when administrative costs related to timber logging are included.

Opis:
Forest communities dominated by noble broad-leaved trees (maple, lime and ash) in Europe are of elevated scientific and conservation interest for the European Union. In this paper, we first present a synthesis of the maple and ash forests in peninsular Italy. By classifying these forests, we distinguish seven main groups for the territory, which only broadly match the syntaxa proposed in the literature. The variability of the Apennine data is then analysed floristically and phytogeographically (using chorological components) in a central-southern European context, using numerical classification, INSPAN, and direct ordination of several synoptic tables. These analyses allow us to identify six different groups of European Acer-Fraxinus communities. Canonical Variates Analysis (CVA) of the geographical components confirms the existence of distinct phytogeographical groups. In particular, we highlight the clear distinction between central European (including the Alps) and southern European coenoses. Among the latter there was a clear floristic and chorological distinction between Balkan and Apennine groups. These results reflect the biogeographical subdivisions of Europe, but do not support the syntaxonomical schemes proposed by other authors, which are based only on floristic-ecological information or (recently) use a smaller data set of Italian relevés. This study also shows that syntaxonomical schemes above the association level should pay more attention to phytogeographical aspects rather than focus on floristic-ecological information alone, in order to propose models that are of value on a geographical scale.

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:
The Forest of Upper Alibori is subject to strong agricultural and pastoral pressures from year to year despite the implementation of a forest management plan. It is therefore appropriate to conduct an integrated and spatialized analysis of the effects of these pressures on plant biodiversity from a spatial planning perspective. The research objective is to establish a multi-criteria zoning of the Upper Alibori Forest Reserve that can reconcile biodiversity conservation and sustainable agropastoral exploitation. A methodological approach based on geomatics was adopted. Hierarchical multi-criteria analysis and cross-layer analysis are the main techniques adopted. The state of plant biodiversity, one of the important criteria for multi-criteria zoning. The intersection of the scientific zoning and the zoning proposed by the riparian population shows a similarity of 54%. In the central core, the similarity between the two types of zoning is 32%. Spatially, this similarity is observed along the Alibori River. At the level of the agricultural series, the two zonings show a similarity level of 23%. The elaboration of an integrated zoning made it possible to distinguish several management series. The management series delimited are made up of the central core (32%), the protection series (11%), the production series (17%), the scientific research series (2%), the service series (2%) and the agropastoral and reforestation series (36%). The implementation of such zoning is the responsibility of the forest administration.

Opis:
Praca zawiera przegląd czynników wpływających na obumieranie drzewostanów w Nadleśnictwie Ujsoły oraz przedstawia sposoby walki z tymi czynnikami, podejmowane przez Nadleśnictwo. Wykazano, że istnieją zagrożenia naturalne i sztuczne, które negatywnie wpływają na stan zdrowotny lasów w Nadleśnictwie Ujsoły. Do ich oceny wykorzystano dostępne materiały z tego Nadleśnictwa, wyniki wywiadu z jego pracownikami oraz informacje ankietowe uzyskane od miejscowej ludności, a także własne terenowe obserwacje. Z przeprowadzonych badań wynika, że najbardziej negatywny wpływ na stan zdrowotny lasów Nadleśnictwa Ujsoły mają owady, głównie kornik drukarz. Szkodnikami są grzyby, zwierzęta, a także niektóre czynniki klimatyczne. Ich unieszkodliwienie jest trudne, ale może je osłabić prawidłowo prowadzona gospodarki leśna zarówno przez nadleśnictwo, jak i prywatnych właścicieli lasów.
This article includes an overview of factors affecting the decay of forest in the Ujsoły Forest District and presents ways to combat these factors, carried out by the Forest District. It was shown that there are natural and artificial hazards that have a negative impact on the health condition of forests in the Ujsoły Forest District. Their evaluation was based on the materials made available by the Forest Inspectorate, the results of the interview with its employees and survey information obtained from the local population, as well as own field observations. The research shows that the most negative impact on the health condition of forests in the Ujsoły Forest District are insects, mainly spruce bark beetle. Pests are fungi, animals, as well as some climatic factors. Their disposal is difficult, but it can be weakened by properly managed forest management by both the forest inspectorate and private forest owners.

Opis:
Maintaining biological diversity is one of the main goals of modern forestry. To reach this objective we need to know how management practices affect forest species. This study summarizes the results published in papers on the influence of clear−cutting on small mammals. Most of the studied species increased in abundance on clear−cuts. The response of voles (Microtus agrestis and M. arvalis) was uniformly positive. Mice (Apodemus flavicollis and A. sylvaticus) and shrews (Sorex araneus and S. minutus) varied in their responses but generally their number increased on clear−cuts. Bank voles (Myodes glareolus) appeared to be associated with the heterogeneity of habitat rather than with the age of forest stands per se. Nevertheless, our knowledge on the effects of forest management on small mammals is far from complete. In particular, there are almost no studies on the subject conducted in Western Europe or concerning management practices other than clear−cutting.

Opis:
Nearly 3.5 million hectares of forest were contaminated by radioactive effluents from the Chernobyl Nuclear Power Plant. Pinus sylvestris L. is the species most sensitive to radiation. Pine wood showed the lowest levels of potential 137Cs activity, while in assimilatory apparatus and bark such activity was highest. Among the non−wood products, mushrooms, berries, medicinal plants and venison that feature the highest ability to accumulate radioactive elements. Partial cuts ensure canopy closure of stands and reduce the vertical and horizontal radionucleide migration. Afforestation is one of the main land reclamation methods applied in contaminated areas. Mechanical planting with limited tending of plantations is used most often there. In cutting areas with a radioactivity level dangerous to carry out regeneration operations, natural regeneration is used exclusively.

adaptability of forest management
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.
