Opis:
Modern measuring equipment is sometimes used for applications, for which it has not been originally designed. For example Ground Penetrating Radar (GPR), designed for subsurface structures analysis, can be used for tree tomography. Radar utilizes the phenomenon of propagation of the electromagnetic waves in a physical medium. Measurements can be carried out in situ, in a non-invasive manner on a living tree. Collected data allow for the tree condition determination. It is possible to detect voids and internal structure. Geophysical investigations can provide an estimation of the risk of falling of the trees. These methods also allow determination of the production quality of the tree by detecting knots inside the structure. Available literature shows only limited examples of the usage of other geophysical surveys, such as the ultrasound and geoelectrical method. However, in many cases these measurements are performed on samples in the form of profiles cut from the felled trees. Presented study was conducted on a set of 8 ash trees growing in the Krakow city parks. The measurement was carried out with high frequency antenna – 1600 MHz. Due to the lack of available literature and limited experience of the authors, only trees with known condition were tested. Despite many attempts, the authors were not able to developed a reliable measurement methodology which would allow for unambiguous classification and interpretation of results. In most cases, the results of the study permitted determination of the trees condition. However, some echograms, of the surveyed trees with visible voids pointed to a different tree state and misclassification. Despite that, the research results seem to be promising and the authors believe in the usefulness of the further development of measurement method along with its extension to other trees species.

Opis:
Forest management is a scientific discipline designed to develop methods of maintaining forest areas and to ensure the sustainable development of forest resources in terms and conditions of multifunctional forestry. This is a branch of practical forestry which deals with inventorying and assessing the state of forests, defines economic tasks and draws up a program of nature conservation for forest districts. The paper presents legal conditions related to the concept of forest management plan, as well as issues related to the area division, planning economic indications and their role for the forest environment. Authors present a forecast of impact of a forest management plan on the forest environment and the Natura 2000 sites.

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.

Opis:
Whilst, in many countries, the scale of forest loss from business-as-usual development is immense, in Poland, this problem does not exist. However, obtaining additional land areas for afforestation is a main issue in Poland. In Poland, after the World War II, the forest area has been systematically growing. In 1945, the forest area was about 6.5 million ha, and the forest cover was 21%. In 2016, the forest area reached 9.2 million ha, and forest cover amounted to 29.5%. Today, there are 0.24 ha of forests per one inhabitant of Poland. The size of wood resources in stands is also changing. In 1945, forest resources on the trunk amounted to approximately 906 million m3 , and in 2016, it reached 2.4 million m3. The problem, however, is the uneven distribution of forests in Poland. Forests in Poland are very strictly protected by law. There are two most important acts, Forest Act of 2001 and Nature Conservation Act of 2004, that regulate principles for the retention, protection and augmentation of forest resources. Over the past decades in Poland, the social demands regarding non-economical functions of forest such as recreational activities, soil and water protection and mitigation of global warming became an important and constantly growing challenge for forest managers. Thus we suggest that, first of all, it is very important to extract the leading function for a given forest area. Interactions between development and conservations policies are very tied and may suggest the need of their integration. In this article, we present the concept of development policy for forest management and forest protection in Poland.

Opis:
Modern forest management requires a well-founded knowledge and understanding of all the risks involved in forest management. It requires a wealth of information not only on natural hazards, but also related to the financial aspect of running a business. The most important activity in the risk management phase is to identify all the known risk areas, and on this basis, to determine the appropriate classification of risks accompanying the activities of the entity in question, taking into account the various categories of risk division. In forest management, the global risk of activities should be considered in terms of two main risks: operational risk (including natural and anthropogenic factors), and financial risk, which, in simple terms, is the consequence of decisions and economic processes in an entity's area of activity. Considering the impact of the production factors that affect the results of the activities carried out, it should be emphasized that forest management has a specific distribution of standard production factors. The forest stand plays the role of both a production resource and an object of production, and in the final analysis, represents a production effect. Any consideration of financial risk management in forest management should be carried out based on long-term analytical data series. Another factor for forests under state management is the various functions that forest management performs. Taking into account the ownership criterion cited earlier, it needs to be emphasized that the weighting of individual financial risks may vary depending on the ownership structure of forests in a given country and taking into account the ownership share of forests in the timber sales market. In conclusion, it was pointed out that, unlike other industries, financial risk management in forest holdings can be disrupted by the function of forests, as well as the strong influence in the long term of natural phenomena that have a significant impact on determining the types and ordering the degree of significance of individual risks in the process of identifying them.

Opis:
The implementation of goals of modern forestry requires a simultaneous consideration of sustainable development of forests, protection, needs of the environment development, as well as maintaining a balance between functions of forests. In the current multifunctional forest model, rational forest management assumes all of its tasks as equally important. Moreover, its effects are important factors in the nature and environment protection. The paper presents legal conditions related to the definitions of forest management concepts and sustainable forest management. Authors present a historical outline of human’s impact on the forest and its consequences for the environment. The selected aspects of forest management (eg. forest utilization, afforestation, tourism and recreation) and their role in the forest environment have been discussed.

Opis:
The conception of sustainable development has been implemented into practice in numerous economic sectors, including forestry. Forest ecosystems are extremely important in the global ecological system, therefore maintenance and appropriate management of forest resources according to sustainable development principles have engaged a great deal of attention. The concept of sustainable forest management (SFM) encompasses three dimensions: ecological, economic and social. A powerful tool to promote SFM are criteria and indicators. The aim of the article was evaluation of SFM in Poland, using one of the methods proposed by the Food and Agriculture Organization (FAO). According to data available, Polish forestry has a number of advantages: Poland has avoided the problem of deforestation, forest area has been permanently increasing, there has been observed improvement of forest health and vitality as well as a significant share of forests has carried out protective functions with no impact on timber production. Poland’s model of SFM is an adaptive process of balancing the ever-changing set of economic, environmental and social expectations. Such a complicated undertaking requires constant assessing and adjusting forest practices, in response to new circumstances, scientific advances and societal input.

2017 marks the 30 years since the The World Commission on Environment and Development has published the Brundtland report “Our common future”. The documents of III Ministerial Conference on the Protection of Forests in Europe and the notations of 1.2 resolution adopted in Lisbon have obliged Poland to run forest management according to the rules of lasting and sustainable development. The forest economy was based on a multi-use forest model with special attention devoted to its environment-creating and social role. The actions which confirmed the introduction of rules of sustainable development into forest practice included: creating 19 Promotional Forest Complexes, systematic increase of afforestation and number of reserves. Designation of Natura 2000 areas in Poland within European Network of Protected Sites was also a very important element. Amongst those areas, as much as 39% are forest ecosystems.

Opis:
Managed boreal pine forests are subject to regular clear cuts causing significant disturbances to these ecosystems. It is believed that, to some extent, they resemble natural cycles of forest growth, decline, and regeneration and can benefit, e.g., mutualistic relations among plants and pollinators. To study the impact of forest management (clear cuts) on pollinator visitation, we focused on three ericaceous plant species, Vaccinium myrtillus, V. vitis-idaea, and Calluna vulgaris, common elements of pine forest understory. Our observations, conducted in Lithuania, showed that there are no differences among control mature stands and clear cut areas in terms of visitation frequency for all three studied species. However, at least for C. vulgaris, a shift toward fly visits was observed in the clear cut site, showing that open areas are preferred habitats for these insects. Ants constituted an important share of visitors to flowers of V. myrtillus and C. vulgaris, suggesting their important role in reproduction of these plant species.
Gospodarcze drzewostany sosnowe strefy borealnej są obiektem częstych zabiegów leśnych, m.in. zrębów zupełnych, powodujących znaczące zaburzenia w tych ekosystemach. Sądzi się, że do pewnego stopnia zabiegi takie przypominają naturalne cykle wzrostu, rozpadu i regeneracji lasu i mogą pozytywnie wpływać na przykład na mutualistyczne związki pomiędzy roślinami i ich zapylaczami. Aby zbadać wpływ gospodarki leśnej (zrębów zupełnych) na odwiedziny zapylaczy skupiliśmy się na trzech gatunkach krzewinek z rodziny wrzosowatych: Vaccinium myrtillus, V. vitis-idaea i Calluna vulgaris, będących częstymi składnikami runa borów sosnowych. Nasze obserwacje, prowadzone na Litwie, generalnie nie wykazały istotnych różnic w zakresie częstości wizyt owadów na kwiatach trzech badanych gatunków roślin w obu siedliskach: dojrzałym lesie i zrębach. W przypadku C. vulgaris na siedlisku zrębowym zanotowano jednak wzrost liczebności muchówek, co może wskazywać na preferencje tych owadów w stosunku do terenów otwartych. Istotna część odwiedzin na kwiatach V. myrtillus i C. vulgaris dokonywana była przez mrówki, co sugeruje, że owady te mogą mieć wpływ na reprodukcję badanych roślin.

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:
High structural diversity is often attributed to old-growth forests, usually established naturally and unmanaged. Forest diversity should be considered not only in terms of species diversity and richness but also the variation in trees dimension and their spatial distribution have to be taken into consideration. The main goal of this paper was the answer if nearest neighbor indices are suitable for spatial forest structure description. To answer this question results obtained from 3 managed beech-dominated forests from natural regeneration are presented and discussed. The following indices were calculated: Clark-Evans aggregation index (R), DBH and height differentiation indices (TD and TH, respectively) and mingling index (DM) analyzing horizontal and vertical spatial structure of the forest. Results indicated that managed beech forests demonstrated rather homogenous spatial structure in both aspects. Living trees as well as future crop trees were mostly regularly distributed. Spatial variation in DBH and height between living nearest neighbors was rather low. The lowest variation in sizes was demonstrated by future crop trees. Mature beech forests revealed single species structure and other tree species – if present – were spatially segregated from beech. It can be supposed that high homogeneity structure of these forests results from biological characteristics of this species as well as thinning treatments conducted by foresters.

The study comprises the analysis of economic activities of the State Forests in Poland in years 1951-1975. The subject of analyses comprises mean five-year values of basic economic tasks, employment structure and remunerations.
Działalność gospodarcza Lasów Państwowych w Polsce po II wojnie światowej była i jest różnie oceniana. Oceny nie zawsze są poparte wnikliwą analizą materiałów źródłowych. W pracy tej przeprowadzono analizę na podstawie materiałów źródłowych Generalnej Dyrekcji Lasów Państwowych oraz roczników statystycznych GUS. Przedmiotem analizy były cztery grupy zagadnień:- zmiany w powierzchni leśnej, w tym rozmiar prac odnowieniowych i zalesieniowych,- zmiany w stanie zasobów leśnych i wynikające z tego różne natężenia pozyskania drewna,- zmiany w zakresie ubocznego użytkowania lasu,- zmiany w zatrudnieniu i płacach.Ze względu na liczbę zagadnień będących przedmiotem analizy, jak i okres badań, w pracy posłużono się wartościami średnimi z pięcioleci z lat 1951-1975. Analiza wykazała dynamikę zmian w poszczególnych obszarach działalności. W analizowanym okresie powierzchnia lasów wzrosła o 0,9 mln ha, co spowodowało wzrost lesistości Polski z około 22 do 27%. Zdecydowanie wzrosły zasoby drzewne na pniu: mniej więcej o 250 mln m3 drewna i osiągnęły w 1975 roku wartość 979 mln m33. W analizowanym okresie wzrosło również pozyskanie drewna i osiągnęło w 1975 roku wartość prawie 25 mln m3. Należy jednak zaznaczyć, że rozmiar pozyskanego drewna był cały czas mniejszy od wartości przyrostu drewna, co świadczy o racjonalnym gospodarowaniu zasobami leśnymi w kraju. W analizowanym okresie wzrosła również liczba zatrudnionych pracowników; swą największą wartość (160 tys. osób) osiągnęła w końcu lat sześćdziesiątych XX wieku.

The model is used as a tool for analysing four donor supported forestry projects in Tanzania, Mozambique, Laos and Vietnam. The study shows that the two core elements for sustaining participation in forest management, regardless of land tenure or forest management model, are: (a) attitude: local people in the specific context see themselves as responsible for the local resources and; (b) access: local people gain secured access to information and benefits from the resources.

Productive European beech stands (Fagus sylvatica L.) involving Scots pine (Pinus sylvestris L.) are formed in Ukrainian Roztochie. Considering value and limited distribution of beech stands involving pine in tree species composition, it is necessary to work out and implement measures for their natural restoration in connection with the climate change and the efficient use of raw materials and non-wood products. Main forestry and management indices of beech stands that include pine in tree species composition were analysed. Forestry activities that are currently carried out in middle-aged and maturing stands significantly reduce their relative completeness and growing stocks, as determined by comparing growth particularities of productive beech stands from different sources.

Opis:
Traditional forest management as coppicing and coppicing-with-standard are recently considered as beneficial for biodiversity in woodlands. Cessation of coppicing leads to changes in stand structure and often loss of biodiversity. In contemporary Polish forestry coppicing is not applied, however some stands of coppice origin persist in Silesia until present. The overgrown coppice oak forests that cover the southern slopes at the foothills of the Sudetes Mountains (Silesia, Central Europe) are considered to be Euro-Siberian steppic woods with a Quercus sp. habitat (91I0): a priority habitat in the European Union, according to the Natura 2000 system. They support one of the largest populations of wild service tree (Sorbus torminalis Crantz) in Poland. In this study we investigated the relation of stand structure and trees parameters with environmental variables. The results showed considerable variability of stand volume, tree density and stems’ size correlated mostly with soil texture, but not nutrient content. We attributed it to soil dryness which seems to be the crucial factor controlling growth of trees. The natural regeneration of trees concentrated mostly on non-exposed sites on less acidic soils, but seedlings of wild service tree were present almost exclusively on most insolated sites, with shallow acidic soils. However, the regeneration of trees in sapling stage was restrained by browsing. Results suggest that maintaining of Sorbus torminalis requires protection against browsing, and some kind of active management is necessary to retain the observed stand structure with high proportion of wild service trees in stands on more fertile soils.
