Opis:

Valuation of forests and their components is a significant problem, both for science and practice. At present, in many countries, the market of forest property is limited. As a result, no conclusions may be inferred on the forest value based on the information on forest purchase and sale transactions. In this situation, we apply static methods of forest valuation. The problem of forest statics has been discussed for years (e.g., Brukas et al. 2001; Chang 1983, 2001; Dieter 2001; Hartman 1976; Manley and Bare 2001; Mohring 2001; Zhang 2001; Viitala 2016). Static methods of forest valuation are well known. In the construction of the proposed mathematical formula (Eq. 6), the Faustmann theory was applied, concerning the economic equilibrium in forestry. Numerous modifications of his equation for economic equilibrium were used to develop, for example, an income method for forest valuation based on discounting the final value or prolongation of initial value. The forest interest rate is a key element in these equations. At present, there are no procedures for the establishment of this interest rate, which would be generally accepted by the scientific community. Therefore, the article presents and discusses selected concepts for determining the forest interest rate.

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.

Objective. The aim of the study was recognition of opinions of forestry employees concerning causes of accidents in forestry, and evaluation of which of the selected demographic characteristics of forestry employees are associated with their opinions concerning causes of occupational accidents. An attempt was also undertaken to answer the question whether there is any relationship between the opinions of forestry employees pertaining to the causes of accidents at work, and observance of the OSH principles concerning the use of protection measures. Materials and method. The survey included 135 forestry employees and conducted by using an author-constructed questionnaire containing items which primarily concerning the causes of accidents at work and the protection measures applied. The opinions of forestry employees pertaining to the causes of accidents were analyzed according to independent variables, such as: workplace, period of employment, age, education level, and an index of the level of the respondents’ concern about OSH (index of the use of personal protection measures by the respondents). The significance of differences between the subgroups selected according to the above-mentioned variables was assessed using the chi-square test. Results. Forestry employees most frequently indicated such causes of accidents as the lack of e use of protection equipment (63.7%), bravado and neglecting hazards (63%), as well as entering or staying in a danger zone during tree felling (56.3%). Nearly a half of the respondents (48.1%) mentioned as the cause of accidents the improper and self-willed behaviour of an employee. The respondents additionally mentioned being taken by surprise by an unexpected event (40%), and the inadequate state of machinery, equipment, and vehicles (36.3%). Conclusions. Based on the results of the study concerning the causes of accidents in forestry, it was found that the examined forestry employees show high awareness and knowledge concerning the causes of occupational accidents in forestry. The greatest differences in the way of perceiving the causes of accidents and hazards were observed according to the respondents’ period of employment and age. In addition, a relationship was observed between indication by the respondents of specified causes of accidents, and the scope of their use of protection measures.

Opis:

The article analyzes the theoretical aspects of using the outsourcing scheme in the enterprise activity, identifies the ways of separating woodworking shops from the structure of state forestry enterprises and justifies the necessity of using the outsourcing scheme in the field of rendering services in forest rehabilitation and reproduction. The purpose of the research is to develop theoretical and practical recommendations for the improvement of forest management in Ukraine through the use of outsourcing scheme in the field of forestry services and wood processing. The object of the research is economic relations in the field of forestry in Ukraine. The method of normative analysis is used to determine the basic norms, which are guided by the subjects of management in the field of forestry in Ukraine; abstractlogical method is used to identify contradictions in the existing system of forestry activities; axiomatic method is used to identify conflicts of interest in the activities of employees of state forest enterprises; the method of institutional comparative analysis is used to determine the main shortcomings of state regulation of entrepreneurship and to substantiate ways to eliminate them. The separating woodworking shops from the structure of state forest enterprises will simplify the management system of these enterprises, reduce administrative costs, increase revenues from the sale of unprocessed timber and increase competition in the market of unprocessed timber.Involving for rendering services in forest rehabilitation and reproduction third parties will create conditions for deepening the division of labor and the specialization of forestry contractors and improving the quality of services which provided, that in result will allow forestry companies to purchase these services at lower prices and higher quality. In case of establishing the requirement for the purchase of all forestry services through free-range tendering, third-party forestry service providers will be able to develop their own production without establishing corruption-related links with the management of state forest enterprises. The positive moment of postponement of the proposed measures for the state is to simplify and streamline economic relations in the forest sector, reduce the level of economic crime and increase the level of tax revenues to the state and local budgets.
У статті досліджено теоретичні аспекти використання схеми аутсорсингу в діяльності підприємства, визначено шляхи відділення деревообробних цехів із структури державних лісогосподарських підприємств України та обґрунтовано необхідність використання у сфері надання послуг з лісовідновлення й лісорозведення схеми аутсорсингу. Метою дослідження є розробка теоретичних положень і практичних рекомендацій з удосконалення лісогосподарської діяльності в Україні шляхом використання у сфері надання лісогосподарських послуг та деревообробки схеми аутсорсингу. Об’єктом дослідження є господарські відносини у сфері лісового господарства України. Метод нормативного аналізу – для визначення основних норм, якими керуються суб’єкти господарювання у сфері лісового господарства України; абстрактно-логічний метод – для виявлення суперечностей в існуючій системі лісогосподарської діяльності; аксіоматичний метод – для виявлення конфлікту інтересів у діяльності працівників державних лісогосподарських підприємств; метод інституціонально-порівняльного аналізу – для визначення основних недоліків державного регулювання підприємництва та обґрунтування шляхів їх усунення. Відділення деревообробних цехів із структури державних лісогосподарських підприємств України дозволить спростити систему управління цими підприємствами, знизити адміністративні витрати, збільшити доходи від реалізації необробленої деревини й посилити конкуренцію на ринку. Залучення до виконання послуг з лісовідновлення та лісорозведення сторонніх суб’єктів господарювання створить умови для поглиблення поділу праці, спеціалізації лісогосподарських підрядників і підвищення рівня якостінадаваних послуг, внаслідок чого лісгоспи зможуть закуповувати ці послуги за нижчими цінами й вищою якістю. У випадку встановлення вимоги закупівлі усіх лісогосподарських послуг через процедури вільних торгів сторонні підприємства-надавачі лісогосподарських послуг зможуть розвивати власні виробництва без встановлення корупціогенних зв’язків з керівництвом держлісгоспів. Позитивним у запропонованих заходах для держави є спрощення та упорядкування економічних відносин у лісовій сфері, зниження рівня економічної злочинності й зростання рівня податкових надходжень до державного та місцевих бюджетів.

Opis:

Objectives: This article compares 2 variants of logging technologies at the motor-manual level: variant A – cutting and delimbing by means of a petrol chainsaw, skidding with the use of a cable winch mounted on a tractor (67–74 kW); variant B – cutting by means of a petrol chainsaw, skidding, debranching and cutting to length by means of a processor aggregated with a farm tractor (61 kW). Material and Methods: Direct dosimetry and non-parametric (moving block bootstrap) methods were used in order to specify the characteristics of the collected sets. Results: Bootstrap average values show that the average CO concentration at a skidding tractor operator’s station during early thinning was 2.54 mg×m⁻³. At processor operator’s station it amounted to 10.35 mg×m⁻³. Such results allow to conclude that a higher CO concentration at the above-mentioned 2 work stations was observed during early thinning. In the case of a petrol chainsaw operator, it was observed that the permissible exposure limit (23 mg×m⁻³) was exceeded and the short-term permissible exposure limit (117 mg×m⁻³) was not. The average concentration value for a chainsaw operator working individually during late thinning interventions was substantially lower (15.01 mg×m⁻³), which results from the lack of technological pressure that can be observed while cooperating with a processor operator. Conclusions: The risk increases along with conditions that generate the concentration of exhaust produced by 2-stroke petrol chainsaw engines.

Objectives: The aim of the study was to survey the prevalence of human hantavirus infections among forestry workers, who are considered a risk population for contracting the disease. Sera collected from volunteers were tested for antibodies against Dobrava-Belgrade (DOBV) and Puumala (PUUV) viruses. Material and Methods: For serological analyses, full capsid proteins of DOBV and PUUV viruses were produced in a bacterial expression system, while Ni-resin was used for protein purification. Samples were screened for anti-hantavirus antibodies by ELISA, results were confirmed by Western blot analysis. Results: A total of 835 samples collected from 750 males and 85 females were tested by indirect ELISA and positive test results were confirmed by Western blot assay. Out of the 45 ELISA-reactive samples, 38 were confirmed by Western blot analysis. The regional distribution of seropositive individuals was as follows: 1.9% (2/107) in the Danube-Tisza Plateau (Great Plains), 3.1% (10/321) in the Southern Transdanubian region, 5.2% (13/248) in the Northern Transdanubian, and 8.2% (13/159) in the North Hungarian Mountains. Conclusions: Our data show marked geographic differences in seroprevalence of pathogenic hantaviruses within Hungary, indicating elevated exposure to hantavirus infections in some areas.

The article discusses the project of good practices for the manager of the urban protection forest, i.e. a model and universal set of protection and management guidelines necessary for the proper shaping of forests in a city. The set of guidelines proposed as the Chart of the Urban Protection Forests includes: shaping multigenerational tree stands; a gradual and spread over time succession of tree generations; maintaining old-growth forests and biocenotic trees in the largest possible number, on the largest available area; the continuous presence of older and middle-aged trees in every part of the forest; resignation from clear-cutting in renewing of tree-stands; promoting and making full use of natural regeneration of tree-stands; passive protection of waterside and wetland forests; active protection of natural diversity as needed; shaping and reconstruction of tree-stands, especially in the habitats of pine and mixed forests; using sanitary pruning when necessary to maintain the durability of tree-stands; complete abandonment of plowing in forest regeneration; zoning; designation of restricted animal sanctuaries; participation and co-responsibility of the society. The introduction of the proposals contained in the Chart of the Urban Protection Forests, at least in part of the protection forests in the cities, could certainly contribute to increasing social acceptance for forest management and avoiding unnecessary conflicts around urban and suburban forests.

Against the background of the solutions laid down in successive editions of Principles of forest management the paper presents their vital role in the shaping of the sustainable multifunctionality of Polish forests and forest management. It has been demonstrated that that the „Principles” of 1953/1955, which were based on ecological foundations and approached forest as an ecosystem, allowed to meet the economic and social goals of forest management. The subsequent editions of the „Principles” were open to any proposal that takes account of the nature and forest−related knowledge, as well as of social and economic conditions of functioning of the forest holding.

Introduction and Objectives. Holding determined body postures during work is connected with muscles activity. The more forced the posture, the larger the number of muscles taking an active part in holding and stabilizing the work posture. During logging, the greatest share of awkward (forced) working postures occurs in tree felling by chainsaw. Materials and Method. A group of 10 experienced fellers aged 47.5±7.3 (37 – 59-years-old) was studied. Heart rate (HR) was measured during simulation of felling activity in 4 working postures: back bent forward with straight legs (stoop), back bent forward with bent legs (flexed-stoop), squat and kneeling on one knee (half-kneel). Results. The lowest value of HR was noticed for squatting – 114.1 bpm, then for kneeling on one knee – 116.3 bpm. HR during felling in a standing posture with straight legs amounted to 121.5 bpm and for standing with bent legs 125.3 bpm. For all studied postures the differences in average HR values were statistically significant at p<0.01. Conclusions. A working posture during tree felling by chainsaw has influence on the level of physiological workload of an operator. Standing bent forward body postures cause higher heart response than squatting and half-kneeling.

Opis:

The paper presents trends in average annual soil moisture in the area covered by the sixty-year old pine stand. The area of analysis is located in the Tuczno Forest District, the Martew Forestry, in the north-western part of Poland. The calculations were based on the measurements of soil moisture at seven different depths below the ground level. A set of probes was installed for measuring the moisture using TDR method in order to calculate retention changes in the unsaturated zone. Humidity measurements used in this work were carried out at daily intervals throughout the year 2014. Designated trends were analysed using the non-parametric Mann – Kendall test, which is used for detecting trend of hydrological and meteorological parameters. Negative values of the Mann-Kendall statistics point to a declining trend for most – six out of the seven, analysed levels of measurement. The tendency toward dryness was not confirmed by the data set of precipitations. Although precipitations are considered to be the main driver of variations in soil moisture their impact severity seems to be controlled by other characteristics of the catchment area and components of the water balance, such as evapotranspiration.

Opis:

Foresters, considering the character of their work, are exposed to the occurrence of many types of diseases. The main occupational risk among forestry workers is caused by infectious pathogens, the main reservoir of which are wild animals, and the vector are ticks. Forestry workers are exposed to the effect of repellents, including DEET (N,N-diethyl-m-toluamide) in association with protection against tick and mosquito bites. The goal of the project was to discover the amount of DEET identified in the samples of sweat and urine from the foresters who use chemical agents repelling insects. The study covered 22 foresters from the Janow Lubelski Forest District, and 10 individuals who constituted a control group. Questionnaires concerning the use of repellents, and urine samples were collected (2 from each person in the study), as well as sweat samples (4 each). Each collected biological sample was properly prepared and subjected to chromatographic analysis (GC/MS) for the identification of DEET. The season of repellents use is from March–October, or even November. The highest intensity of the use of repellents (as many as 5 days a week) is during the period from May–July. The chromatographic analyses performed did not show even the lowest content of DEET in the collected biological samples from both the control group and foresters. The absence of DEET in the foresters’ urine may be explained by the late date of collection of the samples – in October, when they no longer use repellents, or use them very rarely. The studies conducted within this project allowed the observation that DEET is not accumulated, is subject to quick elimination from the body, which favourably affects the safety of its use. Exposure to chemical occupational hazards in forest areas is an underestimated problem of occupational medicine and public health, which has not been fully explored.
Leśnicy z uwagi na charakter wykonywanej pracy narażeni są na występowanie różnego typu chorób. Głównym zagrożeniem zawodowym dla pracowników leśnictwa są patogeny zakaźne, których głównym rezerwuarem są dzikie zwierzęta, a wektorem kleszcze. Pracownicy leśnictwa są narażeni na działanie repelentów w tym DEET (N,N-dietylo-m-toluamid) w związku z ochroną przed ukłuciami kleszczy i komarów. Celem projektu było poznanie, jaka ilość DEET zostanie zidentyfikowana w próbkach potu i moczu pochodz ących od leśników, którzy stosują środki chemiczne odstraszające owady. W badaniach wzięło udział 22 leśników Nadleśnictwa Janów Lubelski oraz 10 osób stanowiących grupę kontrolną. Zostały zgromadzone ankiety dotyczące stosowania repelentów oraz zostały zebrane próbki moczu (po 2 od każdej osoby badanej) i próbki potu (po 4). Każda z zebranych próbek biologicznych została odpowiednio przygotowana i poddana analizie chromatograficznej (GC/MS) celem identyfikacji w nich DEET. Sezon stosowania repelentów przypada na okres od marca do października, a nawet listopada. Największe natężenie stosowania repelentów (bo aż 5 dni w tygodniu) przypada na okres od maja do lipca. Przeprowadzone badania chromatograficzne nie wykaza ły nawet najmniejszej zawartości DEET w zgromadzonych próbkach biologicznych pochodzących zarówno od grupy kontrolnej, jak i od leśników. Brak obecności DEET w moczu leśników należy tłumaczyć późnym terminem zbiorem próbek – w październiku, kiedy leśnicy nie stosują już repelentów lub stosują bardzo rzadko. Badania przeprowadzone w tym projekcie pozwoliły zaobserwować, że DEET nie jest akumulowany, podlega szybkiej eliminacji z organizmu, co wpływa korzystnie na bezpieczeństwo jego stosowania. Ekspozycja na chemiczne zagrożenia zawodowe na obszarach leśnych jest niedocenionym i nie do końca zbadanym problemem medycyny pracy i zdrowia publicznego.

Opis:

The knowledge on chorology of species is basic for biogeographic and ecological studies and for conservation actions. The data on the chorology of Taxus baccata in Morocco have not been studied. The bibliographic resources, herbarium material, unpublished data of several botanists and the authors’ field notes have been reviewed. Two yew populations on Jbel Lakrâa in the Rif and near Bekrit in the Middle Atlas were measured to verify demographic structure and health conditions. The Maxent model of predicted habitat based on bioclimatic variables was used to evaluate the potential geographic range of T. baccata. The species occurs in the mountain areas of northern Morocco: in the Rif, the Middle and High Atlas, at altitudes between (500) 1200 and 2000 (2350) m. In the High Atlas, it reaches its southernmost locations within the geographic range. The populations represented by the highest number of individuals are found in the Western Rif and Middle Atlas, while from the High Atlas only single, isolated individuals are known. The yew occurred preferably in forests of Cedrus atlantica, Abies maroccana, groves of Betula fontqueri, Ilex aquifolium and Prunus lusitanica and in riparian forests located in narrow gorges. Seedlings were observed only at single localities. The population of T. baccata in the Rif presented a good health condition with successful regeneration, while the population in the Middle Atlas was in a much worse state, where only 4–8 m high yews were observed, without natural regeneration. The Maxent model of predicted habitat, based on bioclimatic variables, suggests that T. baccata could occur today in much broader mountainous areas in Morocco, especially in the Rif and Middle Atlas. However, the progressive decline of this species in Morocco indicates the significant importance of other factors on yew distribution, including microsite conditions and human pressure. Taxus baccata in Morocco is in regression at most of its localities and should be treated as a vulnerable species. Measures to ensure the yew’s conservation are needed, especially at its southernmost localities in the High Atlas.

Opis:

Introduction. Researchers indicate an important relationship between the level of job satisfaction and the state of health of the employees. Some elements of work related with its character, organization, and interpersonal relationships may evoke strong stress, manifested by, among others, an increased musculoskeletal tension which, in turn, may lead to permanent dysfunction of this system. Objective. The objective of the study was analysis of the relationship between the level of job satisfaction and occurrence of musculoskeletal disorders among employees of the State Forests. Materials and method. The research material was collected using two instruments: the modified Nordic Questionnaire for assessment of musculoskeletal disorders, and a questionnaire concerning job satisfaction. The study was conducted in a group of 396 employees of the State Forests from 8 regions of Poland. Results. The results of analysis confirmed a significant relationship between job satisfaction and the occurrence of musculoskeletal disorders. The lower the level of job satisfaction, the more frequent the experiencing of musculoskeletal disorders. Conclusion. Low level of job satisfaction is a risk factor for the occurrence of musculoskeletal disorders. Shaping of work conditions, which are the source of job satisfaction, should be considered as one of the main elements of prevention of musculoskeletal complaints.

ObjectivesThis study examined the physiological strain experienced by workers employed in motor-manual timber harvesting performed in winter and summer, and the applicability of heart rate indices for estimating energy expenditure.Material and MethodsThe heart rates (HR) of 2 teams consisting of 2 persons working simultaneously during felling and forwarding, in both winter and summer, were measured. Heart rate at work (HRwork), resting heart rate (HRrest), relative heart rate (%HRR), ratio of working heart rate to resting heart rate, and 50% level were used to estimate the physiological workload in particular jobs. The HRindex (HRwork/HRrest) equation was used to estimate the energy expenditure (EE). ResultsFor all jobs, significantly higher physiological workload and energy expenditure were recorded during winter.ConclusionsThe season significantly affects the physiological workload during logging operations. If there is no possibility of harvesting wood in summer, in order to limit the workload of workers during winter activity, attention should be paid to the proper organization of work and selection of workers.

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.

Introduction and objective. The aim of this study is to assess the interpersonal relations of employees of State Forests in Poland, as well as to indicate the factors related to the level of satisfaction with the relations among people employed in similar positions, and relations with superiors. Materials and method. The issues investigated were developed based on research conducted between 2014–2015 among employees of State Forests in Poland. In each of the 9 forest districts selected, 25 people were selected for testing from 3 groups of employees: foresters, deputy foresters and supervisors, together with administrative staff. Altogether, 399 people took part in the study conducted by means of a questionnaire. Results. The study showed that the overall level of satisfaction with interpersonal relations among employees of State Forests in Poland is high. Analysis indicated that the demographic characteristics of respondents, such as age, gender or place of residence, had no significant influence on satisfaction with interpersonal relations in the workplace. However, the level of satisfaction with interpersonal relations was positively affected by a high level of overall job satisfaction and satisfaction with remuneration. Decrease in the level of satisfaction was influenced by the accumulation of stressful life events and employment in administration. Conclusions. Satisfaction with interpersonal relationships in the workplace is an important indicator of employee mental health. Studies have shown the need to broaden the scope of research into the variables that determine the character and personality of an employee.

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.

The current and the potential importance of the bio-economy is illustrated with data from Germany. While the potential uses of biomass are manifold, its availability is limited. This paper discusses the resulting competition for biomass and shows possibilities to increase the biomass-potential. To satisfy the increasing demand for biomass, further research in the forestry sector is needed.

Opis:

The study was undertaken in the region of the Białowieża Primeval Forest (Białowieża, Browsk, and Hajnówka Forest Districts – FDs), which has a total area of 52 thousand hectares and is situated in the agricultural zone of north-eastern Poland. The study used an input-output (I-O) analysis to explore: 1) the type and strength of relationships between forest management and its socio-economic environment, and 2) the role and significance of forestry in the development of the region. The forest sector (FDs) employed 452 people, with salaries totalling USD 1.6 million/yr. FDs supplied the socio-economic environment with the generated cash flows (taxes and dues) amounting to USD 4.8 million/yr, enabling creation of 413 jobs outside forestry. FDs supplied goods and services for the amount of USD 5.2 million/yr, mainly revenues from the sale of 120,000 m3 of harvested wood. The wood-processing industry employed 1,111 people, and was also a source of taxes and dues amounting to USD 1.7 million/yr. Fifteen jobs were created per 1,000 m3 of harvested, sold, and processed wood: 2 in FDs, 4 in the firms providing goods and services, and 9 in the recipients of goods and services. Simultaneously, this was a source of taxes amounting to USD 26.0/yr, of which USD 11.0 thousand/yr was paid by FDs, USD 1.4 thousand/yr by the environment of suppliers, and USD 13.6 thousand/yr by the environment of recipients.
Celem badań było ustalenie rodzaju i siły powiązań gospodarki leśnej z otoczeniem społeczno-gospodarczym oraz konsekwencji dla miejscowych gmin i ich mieszkańców w kontekście planowanego powiększenia obszaru Białowieskiego Parku Narodowego (BPN) o trzy nadleśnictwa (Białowieża, Browsk, Hajnowka). Badania przeprowadzono za pomocą metody analizy przepływów między sekcyjnych (input‑ output analysis). Dotyczyły one rynkowych powiązań gospodarki leśnej (trzech nadleśnictw) z otoczeniem społeczno-gospodarczym. W badaniach pominięto natomiast powiązania nadleśnictw z otoczeniem związane ze świadczeniem pozaprodukcyjnych funkcji gospodarki leśnej, ktore nie są rejestrowane w dokumentach finansowo-księgowych. Uzyskane wyniki badań wskazują na liczne powiązania gospodarki leśnej z otoczeniem społeczno-gospodarczym oraz na duże znaczenie leśnictwa w rozwoju obszarów wiejskich tego regionu. Świadczą o tym m.in. następujące wskaźniki: Nadleśnictwa, zakłady usług leśnych i zakłady przerobu drewna stworzyły bezpośrednio i pośrednio ogółem 1976 miejsc pracy. 1. Każdy 1 tys. m3 pozyskanego surowca drzewnego w nadleśnictwach BPN tworzy 15 miejsc pracy. 2. W ujęciu wartościowym, pozyskany surowiec drzewny o wartości 2 714 USD generuje jedno miejsce pracy. 3. W przeciętnej cenie 34 USD/m3 drewna pozyskanego w nadleśnictwach BPN opłaty i podatki na rzecz budżetu państwa i gmin stanowią 33%, tj. 11 USD. 4. 1 m3 drewna pozyskanego i przerobionego w BPN, którego przeciętna wartość w gotowym produkcie wyniosła 97 USD obciążony jest opłatami i podatkami w wysokości 26 USD (27%) wartości produktu finalnego, w której: – 21 USD/m3 stanowią opłaty i podatki odprowadzone do budżetu państwa, – 5 USD/m3 opłaty i podatki trafiające do budżetów gmin. Przedstawione wskaźniki syntetyczne obrazują istotne znaczenie lasu i gospodarki leśnej dla rozwoju gmin w otoczeniu BPN i lokalnej społeczności. Włączenie nadleśnictw do parku ograniczyłoby wpływ leśnictwa na rozwój obszarów wiejskich. Ocena skutków gospodarczych i społecznych tego przedsięwzięcia wymaga dalszych badań.

Opis:

Livestock sector forms an important livelihood activity for farmers, through supporting agriculture and supplementing income in India. The lack of availability of sufficient feed is one of the major limiting factors for better productivity of livestock. The feed are of two types as roughages (high in crude fibrous material) available at public forest, farm lands, etc. and concentrates (high in nutrients and mixture of oil, coarse grain, and cereals). The general degradation of forest reduces the fodder availability, severely. Therefore, improving forest condition may provide pathways for sustainability of both, livestock and forest. This may be addressed through sustainable forest management, which requires scientific inputs and may be shifting of some demand of locals to other resources. This requires huge amount from government. Presently, livestock sector is part of the Agriculture and Allied Activities sector in the accounting system of India, and therefore, all related shares and expenditure is part of the component. This results into under allocation for the actual shares of forestry contribution to livestock, in the Forestry and Logging sector. This occurs primarily, due to the lack of scientific information on the share and value of fodder from forest. This study has been undertaken to estimate the share and economic value of forests derived livestock feed. Primary data has been collected as per pretested questionnaire from 316 randomly selected households engaged in livestock rearing from 66 villages distributed across the Uttarakhand, India. Information pertaining to the fodder to livestock from all sources and socio-economic attributes were collected from each household to understand the feed consumption behavior of livestock. The feed sources were classified in forests, other than forests and market. The shares and economic value of livestock feed derived from different sources has been estimated for all livestock. The prices of various feeds were either collected directly from market or estimated through non market valuation techniques based on two scenarios (contingent valuation and ratio of dry and green matter basis of 0.40). The average proportion of feed quantity consumed by livestock was 58% from forests, 39% from other than forests and 3% from markets for hilly region. It was 97% from other than forests and 3% from markets for plain region. For hilly region, the proportion of economic value varies from 40– 41% for forest; 40– 41% for agriculture and 18– 20% from market. The total value of forest fodder was Rs 4811 millions in scenario 1 and Rs 5209 millions in scenario 2 for the Uttarakhand. The study concludes and recommends that these proportions may be utilized to allocate the appropriate share of livestock feed into Forestry and Logging sector, which may results into the realistic share of the sector.

Introduction. According to the European Occupational Diseases Statistics (EODS-2005) diseases related with musculoskeletal disorders occupy the first position on the obligatory list of occupational diseases. These disorders most frequently occur in the agriculture-hunting-forestry sector in such countries as: Finland, Holland, Germany, France and Spain (data: EU-OSHA). Materials and method. The study included a selected group of males – 414 forestry workers, employees of the State Forests, aged 25–65, mean age 48. The control group were 119 office workers aged 23–64, mean age 45.8. The basic research instrument was a questionnaire designed by specialists concerning pain complaints occurring in 7 areas of the motor system: neck, arms, upper and lower back, hips, knees and feet. Results. The results of the survey showed that in the selected group of forestry workers, among 7 investigated areas of the motor system, the most frequently reported pain complaints involved the lower part of the spine (272 persons, 65.7% of the total number of respondents). In the control group such pain complaints occurred in 55.5% (66) of office workers (p = 0.04). Forestry workers most often described this pain as permanent, radiating to the leg, or as an acute pain. According to the frequency of reporting pain, the area of the knees was placed on the second position (214 foresters; 51.7%). Conclusions. The work of a forester which consist, among other things, in relocation on foot or by vehicle over long distances along an uneven terrain and in various weather conditions, is a risk factor of the occurrence of musculosceletal disorders concerning the low back and knees.

Opis:

Photogrammetry started to develop in Poland after World War I. Although relatively very important and big photogrammetric projects from this time are known, only few mentions are related to the use of photogrammetry for forestry purposes. On early 1945 the demand for the development of photogrammetric products – photomaps – reported six ministries, including the Ministry of Forestry. Forest applications of photogrammetry were developed by workers employed in Forest Research Institute – Gieruszyński (1948 ) and Stanecki (1951) published first books concerning the use of aerial photographs for measuring and determining the forest characteristics and estimation of wood volume. Aerial photographs found wide use in forestry from the second half of the 1950s, but after 1970 a decline of interest in the use of photogrammetry is to be noticed. The need for a broader use of photogrammetry in forestry pointed the authors of many studies appearing in the scientific literature. In the seventies, research related to the use of simple photogrammetry methods and tools to determine the selected characteristucs of forest stands. There was big interest in methods of determining the amount of trees within stands, their height, crowns closure, and species composition. The second half of the seventies is also the birth of the forest remote sensing. The real revolution in scientific research and applications of photogrammetry and remote sensing takes place from the beginning of the twenty-first century. Two circumstances are conducive to a growing use of photogrammetry and remote sensing in forestry – the emergence of laser scanning (LiDAR) technology and unmanned aerial vehicles. Also thematic scope of research will change – the focus will move from the issues concerning the inventory of stands to tracking dynamic processes of nature. Modern techniques of photogrammetry and remote sensing should also provide new data useful to detect and assess the significance of factors affecting the immunity of forest.

Opis:

The modernization of the cadastre is such a complicated and complex process that may cause many significant results. Cadastral parcel surface areas changes and changes in land use are the most important of them. These factors have also a direct influence on the real estate tax base assessment. Using materials obtained from geodetic and cartographic documentation centres, the analysis concerning the considered problem has been performed. The basic facts connected with the cadastre modernization and legal rules concerning the real estate, agricultural and forestry tax bases determination have been analysed too. It has been proved, that changes in spatial data which have arisen during the modernization of the cadastre, especially in the scope of land use, may have an essential significance for taxpayer. Performed analysis denote, that comprehensive cadastre modernization from proper Municipal and Communal Offices' point of view which are real estate tax collectors, is financially profitable enterprise.

Opis:

Wstęp: Celem pracy była analiza częstości zakażeń Borrelia burgdorferi u pracowników leśnictwa i rolników stanowiących grupy zawodowo narażone na pokłucia przez kleszcze. Materiał i metody: Grupa badana liczyła 275 osób, w tym 171 pracowników leśnictwa oraz 104 rolników. Grupę porównawczą stanowiło 45 osób nienarażonych zawodowo na pokłucia przez kleszcze. Testy przesiewowe Elisa w kierunku IgM/IgG anty-Borrelia oraz testy Western blot wykonano w grupie badanej i porównawczej. Uzyskane wyniki badań poddano analizie statystycznej (test Chi2). Wyniki: U 55% leśników i 28% rolników z terenów Niziny Południowopodlaskiej i Polesia Lubelskiego, którzy zawodowo narażeni są na wystąpienie boreliozy, obecne były przeciwciała IgM i/lub IgG anty-Borrelia. Przeciwciała stwierdzano częściej u leśników (p ≤ 0,00001) i rolników (p ≤ 0,001) w porównaniu z grupą porównawczą. Istotne znaczenie w generowaniu zakażeń u ludzi mają gatunki niebrane dotychczas pod uwagę w Polsce jak B. spielmanii i B. bavariensis. Wnioski: Narażenie na zakażenie B. burgdorferi w zawodzie rolnika i leśnika jest wysokie, a zakażenia krętkami stwierdzane na podstawie pozytywnych wyników testu Wb wyjątkowo częste. Obecność specyficznych przeciwciał dla białek antygenowych B. spielmanii i B. bavariensis sprawia, że należy brać je pod uwagę jako sprawców zakażeń wywoływanych przez nie samodzielnie i zakażeń mieszanych, a także rozważyć ich wpływ na obraz kliniczny zakażenia. Med. Pr. 2014;65(1):109–117
Background: The aim of the work was to analyze the incidence of infection with Borrelia burgdorferi in forestry workers and farmers, major groups occupationally exposed to tick bites. Material and Methods: The study group included 275 workers (171 foresters and 104 farmers). The control group consisted of 45 people, who have not been occupationally exposed to tick bites. The screening Elisa and Wb tests for the presence of anti-Borrelia IgM/IgG antibodies were performed in all subjects of the study and control groups. Statistical analysis was performed using the Chi2 test. Results: The positive results denoting the presence of anti-Borrelia IgM/IgG antibodies were found in 55% of farmers and 28% of foresters occupationally exposed to Lyme borreliosis and coming from the area of South Podlasie Lowland and Lublin Polesie. The differences between the forestry workers and the control group (p ≤ 0.00001) and between farmers and the control group (p ≤ 0.001) were statistically significant. The species, such as B. spielmanii and B. bavariensis, which have not yet been reported in Poland, are significant etiologic agents of Lyme disease. Conclusion: The risk of occupational exposure to the B. burgdorferi infection is high for foresters and farmers, and the infection with spirochetes is frequently confirmed on the basis of positive results of the Wb test. The presence of specific antibodies against protein antigens of B. spielmanii and B. bavariensis suggest that these bacteria can cause Lyme disease both independently and in participation with other Borrelia species, which influences the development of the clinical manifestations of infection.

Opis:

Both COP21 and COP22 stressed the role of forests in climate protection as a natural CO2 sink. With this in mind, the study reviewed some literature findings related to afforestation, stand level management, forest soils, peatland management and storage yards to increase the amount of CO2 absorbed by the forest ecosystem. It was shown that some of the assumptions, for example, afforestation or improved water relations in soils, may contribute to reduced CO2 levels in the atmosphere. Our research was of a review nature and consisted in seeking information in various scientific publications. For a better interpretation of the results, we have divided our research into several parts. In the first part, we analysed the importance of deforestation and afforestation in the context of CO2 accumulation. We discussed the results of research on these issues giving specific examples. We have analysed the possibility of afforestation of new land. Using the example of Poland, we have indicated problems related to this issue. We have analysed the possibility of afforestation of new land. On the example of Poland, we have indicated problems related to this problem. We have come to the conclusion that in today’s Europe, the obstacle to such efforts is the lack of land that can be afforested and the financial incentive to abandon farming for forestry is too low. In the second part, we discussed the role of forest stands in the process of CO2 accumulation and reduction. We discussed breeding treatments that can be performed on racks. We noticed their importance in the CO2 reduction process. We noticed that when the density of forests increased, this has a positive effect on organic carbon storage. We presented and discussed examples of different rotation strategies in the context of their impact on CO2 accumulation. We analysed issues related to obtaining wood raw material and possible further storage of coal or its release into the atmosphere. We have recognized that proper forest soil management is important for CO2 accumulation. Therefore, another part of the research was devoted to the discussion on the role of soil in the process of CO2 accumulation. We discussed examples of using soil for forest and non-forest purposes, looking for the answer: how does this affect CO2 accumulation? In addition, we analysed the impact of soil moisture on processes related to CO2 storage. In our research, we critically treated wood storage as a method of reducing CO2. We also discussed the problem of treating wood as a source of bioenergy. We came to the conclusion that wood as an energy source can have a positive effect on CO2 reduction. The condition is, however, that energy produced from wood replaces energy from fossil fuels. Finally, we presented and discussed financial and legal issues related to CO2 reduction activities involving forests. We have found that attempts to commercialize CO2 emission reduction units for emissions generated in forests should be linked to the environmental responsibility of companies, and as such, should not be included in the current emissions’ trading policies. In the article, we also present a Polish proposal to run coal farms. We discuss their importance in the context of the issues discussed in this article.

precise determination of forest resources is one of the most important tasks in conducting sustainable forest management. Accurate information about the forest’s resources allows for a better planning of current and future management as well as conservation activities. Such precise information is needed by both, individual forest managers and for developing the national forest policy. In recent years, interest in the use of remote sensing in forest inventory has significantly increased. remote sensing allows for non-invasive measurements and the automation of data processing. the most accurate source of remote sensing data at the level of the sample plot is terrestrial laser scanning ( tlS). Its use in forest inventory has been studied for about two decades. this paper aims to introduce studies on state of the art tlS technology as well as provide an overview of research conducted in stands within the temperate climate zone. this article furthermore discusses issues such as tlS data acquisition, data proces- sing and presents results for the estimation of tree biometric features.

Introduction. Work in forestry has been and continues to be considered a very difficult and risky occupation, with constant exposure to certain factors which create risk for employees’ health or even life. The objective of the study is recognition of the opinions of forestry workers concerning health risk, and to evaluate which of their selected demographic characteristics are connected with opinions concerning hazards at the workplace. Materials and method. An author-constructed survey was conducted among 135 forestry employees, containing items concerning primarily hazards occurring at workplaces in forestry. Forestry employees’ opinions pertaining to occupational hazards were analyzed from the aspect of independent variables, such as workplace, period of employment, age and education. The significance of the differences in the subgroups distinguished according to the above-mentioned variables, were assessed using the chi-square test. Results. Forestry employees most often indicated risk related with cold (83.7%) and hot (77%) microclimate. A high percentage of respondents (74.1%) were aware of the presence of biological hazards and risk caused by the possibility of contact with wild animals (55.6%) at their workplace. In addition, a considerable part of workers reported that the source of risk at their workplace is noise (34.1%), especially dangerous machinery (26.7%), dust (18.5%), chemical substances (15.6%), and forced body position at work (14.1%). Conclusions. Based on the results of the study concerning work safety and occupational hygiene among forestry employees, it was found that they are aware of hazards which may occur at their workplaces. The greatest differences in the perception of hazards were observed according to the type of workplace and period of employment.

Opis:

Niniejsze badanie stanowi przegląd opublikowanych danych. Ma na celu zestawienie zebranych informacji na temat stanu prawnego i zagrożeń dla mchów i wątrobowców występujących w ekosystemach leśnych Polski. Grupę szczególnego zainteresowania i pielęgnacji wśród tych roślin stanowią gatunki związane ze starodrzewami, charakteryzujące się wysokim stopniem naturalności. Spośród trzydziestu sześciu gatunków uznanych w Polsce za relikty puszcz osiemnaście uznawanych jest za zagrożone, ale tylko cztery znajdują się na europejskiej czerwonej liście. Jednym z głównych zagrożeń dla tej grupy gatunków epifitycznych i epiksylicznych jest gospodarka leśna, która powoduje zmniejszenie dostępności mikrosiedlisk i pogorszenie mikroklimatu wewnątrz obszarów leśnych. Dotkliwe skutki miały także melioracje terenów podmokłych leśnych i nieleśnych, prowadzone powszechnie w minionych wiekach. Nie ma natomiast znaczących zagrożeń dla mchów epigeicznych występujących na siedliskach mineralnych lasów iglastych i mieszanych. Dlatego właściwa ochrona mchów i wątrobowców epifitycznych i epiksylicznych powinna opierać się na ochronie ich siedlisk. Najlepszym rozwiązaniem jest zabezpieczenie odpowiednich obszarów w zachowawczej formie. W jednostkach przestrzennych wyłączonych z użytkowania drzewostanów powinien utrzymywać się mikroklimat charakterystyczny dla wnętrza lasu. Jest to możliwe jedynie przy ich odpowiedniej wielkości, czyli szerokości przekraczającej dwukrotność wysokości drzewostanu i o ile to możliwe, o powierzchni co najmniej 1 ha. Wartość progowa powinna wynosić co najmniej jedną taką powierzchnię na 100 ha lasów gospodarczych na obszarach cennych przyrodniczo.
This study is an overview of the published data. It aims to compile the information collected on the legal status and threats to the mosses and liverworts occurring in forest ecosystems in Poland. The species associated with ancient forests with a high degree of naturalness consist of a group of particular interest and care among these plants. Among thirty-six species recognized in Poland as relics of primeval forests, eighteen are considered endangered, but only four are on the European red list. One of the main threats to this group of epiphytic and epixylic species is forest management, which causes a decrease in the availability of microhabitats and deterioration of the microclimate inside the forest areas. Drainage of forest wetlands, as well as non-forest ones, carried out commonly in the past centuries, also had severe effects. On the other hand, there are no significant threats to epigeic mosses occurring in mineral habitats of coniferous and mixed forests. Therefore, the suitable protection of epiphytic and epixylic mosses and liverworts should rely on protecting their habitats. The best solution is to protect appropriate areas in a conservative form. The spatial units excluded from the use of the tree stands should maintain a microclimate specific to the forest interior. It is possible only with their appropriate size, i.e., a width exceeding twice the height of the stand, and an area of at least 1 ha, if possible. The threshold value should be at least one such area per 100 ha of managed forests in naturevaluable areas.

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.

Opis:

This study empirically examines the impact of forests on economic growth in Nigeria for the period of 1990 to 2015. Unit root tests were carried out using the Augmented Dickey Fuller (ADF) test, while the Bounds cointegration test was used to establish a long run relationship between the forests and other independent variables and economic growth. An Error Correction Model (ECM) was also employed to determine the nature of the long run relationship. The findings show that forests have a positive effect on economic growth, however, this is not statistically significant. This study recommends that the government should intensify its efforts in the forestry sector so as to improve the productivity of forest resources in Nigeria. Moreover, the Nigerian government should discourage illegal felling of trees and the importation of timber products, as well as engage and develop the rural communities to reduce the pressure on forest resources and ensure sustainable use. The study also recommends the sustainable use of forest resources through ecotourism and the development of the forestry value chain in Nigeria.

Opis:

Użytkowanie lasu jest najstarszą formą działalności człowieka i zachodzi również, jeżeli odbywa się bez fizycz-nej obecności człowieka w lesie, stając się działaniem destrukcyjnym – zamierzonym lub niezamierzonym, lub działaniem kreatywnym – umożliwiającym identyfikację i realizację potrzeb. Użytkowanie takich funkcji lasu jak: kulturowa, moralna, etyczna, religijna i wiele innych, nie zawsze jest kwantyfikowalne, a ich bezpośrednia wycena, w tym ekonomiczna, może być bardzo trudna. Spowodowane jest to zarazem brakiem odpowiednich narzędzi ekonomicznych, jak i metod bezpośrednich analiz środowiskowych, a także nieumiejętnością identyfi-kacji poszczególnych funkcji, jakie pełnią lasy. Artykuł przybliża historię zrównoważonego rozwoju w leśnictwie, poczynając od nakazu dbania o las podpisa-nego w 1364 r. Kolejni, wielcy teoretycy i praktycy leśni (Carlovitz, Cotta, Hundeshagen, Heyer), budowali zwartą, przemyślaną konstrukcje postępowań rozpatrując problemy utrzymania trwałości, ciągłości i równo-mierności użytkowania lasu. Realnym problemem w realizacji koncepcji zrównoważonego leśnictwa i wielofunkcyjnego lasu, jest nierozwią-zywalna trudność w antycypacji oczekiwań przyszłych generacji, co do stanu, wyglądu i zróżnicowania przy-szłych lasów. Należy przy tym zauważyć, że obietnice, jakie niosą za sobą pojęcia używane w zrównoważonej gospodarce leśnej, w odniesieniu do wielofunkcyjności leśnictwa nie mogą być spełnione jednocześnie i na-tychmiast. W praktyce leśnej, wszystkie funkcje jakie pełni las, mogą być spełnione jedynie w bardzo długim horyzoncie czasowym – liczonym długością życia drzew i drzewostanów. Poszukiwania rozwiązań w tym zakresie, powinny obejmować nie tylko obszary nowoczesnej, aktualnej wiedzy, zarówno leśnej, jak i w innych działów nauki, ale także, wiedzy tradycyjnej. To oznaczałoby, również pogodze-nie się z myślą, że wiedza tradycyjna, nie zawsze poparta naukowym oglądem, może być podstawą zrozumienia wielofunkcyjności lasu w kontekście zrównoważonego rozwoju.
Use of the forest is the oldest form of human activity and also occurs if it takes place without the physical pres-ence of man in the woods, becoming destructive action – intentional or unintentional, or creative activity – iden-tifying and implementing specific needs. Use of forest functions such as: cultural, moral, ethical, religious, and many others, is not always quantifiable, and their direct measurement and evaluation, can be very difficult. This is due to both lack of appropriate economic tools and methods for the direct environmental analysis, as well as an inability to identify the various functions played by forests. The article is discussing the history of sustainable development in forestry, which opens with the law signed in 1364 by Philip VI of France, ordering that owners of the forest must take care of it. The next great theorists and practitioners of Forestry (Carlovitz, Cotta, Hundeshagen, Heyer), develop the concept, building a cohesive, well thought-structures of proceedings in the context of preserving stability, continuity and uniformity forest use. The real problem in implementation of the concept of sustainable forestry and forest multifunctionality, is un-solvable difficulty in anticipating the expectations of future generations as to the condition, appearance and composition of future forests. should be noted that promises benefits of the terms used in sustainable forest man-agement (SFM), in relation to the multifunctional forestry cannot be met simultaneously and immediately. In forestry practice, all the forest functions, can be met only in a very long time horizon – calculated life expectancy of trees and stands. The search for solutions in this area should include not only areas of the modern, current knowledge, both the forest and in other branches of science, but also traditional knowledge. This would mean, that traditional know-ledge, significantly important for the practice of forestry, can be the basis for the understanding of the multi-functionality of the forest in the context of sustainable development.

Potrzeby, jak powiadają znawcy przedmiotu, są pożądaniem czegoś niezbędnego do zagwarantowania człowiekowi funkcjonowania i rozwoju. Innymi słowy, zaspokojenie potrzeb warunkuje nasze przetrwanie, stanowiąc przy tym drogę, którą komunikujemy się ze światem i dzięki której kształtujemy sposób naszego życia, systemy wartości oraz relacje z ludźmi. Zajmujący się tą problematyką amerykański psycholog Abraham Maslow stworzył piramidę hierarchii potrzeb, porządkując je od najbardziej podstawowych – związanych z funkcjami życiowymi – do tych z wyższego poziomu, które aktywizują się dopiero po zaspokojeniu tych pierwszych.

Opis:

The urban environment is stressful and trees experience multiple stresses, including drought, flooding, and extreme heat, all of which are likely to increase under future climate warming and increasing urbanisation. In the selection of tree species to maximise ecosystem services, tolerance to site characteristics such as flooding and severe drought is of critical importance. This study evaluated the suitability of a rare species, Alnus subcordata C.A. Mey (Caucasian alder) from the Hyrcanian forests of southern Azerbaijan, for its functionality as an urban tree. A total of 48 pot-grown, two-year-old saplings of A. subcordata were tested in a greenhouse experiment using a complete randomised block design. Each block contained four replicates of three treatments (waterlogging, drought, control), with 16 plants per treatment. Height differences between treatments were measured, and water status was estimated by determination of midday leaf water potential (ΨL) and stomatal conductance (gs ). To estimate drought tolerance reaction in the treatments, leaf water potential at turgor loss (ΨP0) was used together with broken-stick modelling of water status over time. There was a significant difference in tree height between the different treatments. In the drought treatment, A. subcordata plants showed no height increase, while plants in both the waterlogged and control treatments increased in height during the nine-week experiment. Over 63 days of flooding, plant water status was slightly more negative in the waterlogging treatment, but did not deviate essentially from the control. In the drought treatment, plant water status rapidly deviated from the control. There was a significant difference in ΨP0 between treatments, with drought-treated plants showing the lowest value (−2.31 MPa). This study demonstrated that A. subcordata has limited tolerance to drought and seems to rely more on water loss-avoiding strategies. However, the species may be usable at periodically waterlogged sites, due to its high tolerance to flooding. It could therefore be recommended for wet urban environments and stormwater management facilities, for which reliable guidance on suitable trees is currently lacking.

Opis:

The seed orchards (SO) serve possibilities to collect seeds from the selected genotypes or to create artificial population throughout the controlled crossing of the target genotypes. Therefore, the seed material obtained from the clonal and seedling seed orchards offers unique opportunity to improve the genetic value of seeds. Thus, the seed orchards are considered as an important part of the forest seed base being the key object for both modern forestry and forestry research. This paper outlines the forest breeding activities associated with the seed production in the seed orchards in Ukraine over the last 70 years. During this period, the different aspects related to the establishment and management of the seed orchard were studied. In these processes, many failures had occurred, their causes and consequences were described. These main breeding activities were reported considering plain and mountain regions of Ukraine as well as specific aspects of the reproduction of the main forest tree species. As of 2019, the total area of the clonal seed orchards (CSO) reached 1040.3 ha, while seedling seed orchards (SSO) only 273.7 ha. The results of research on the growth, reproductive development, the morphology of the plus trees clones in the SO were generalized. The article on the current problems and challenges for Ukrainian forestry mainly related to forest tree breeding and there was also focus on forest seed industry. For the main forest trees species (Scots pine, English oak and other), targeted breeding programs should be developed. It is relevant to create the genetic bank of the forest seeds.

Opis:

In the article the method of analysis of financial potential using taxonomy method has been developed as well as it has been tested on the basis of empirical data of Ukrainian forestry enterprises. The application of such a method made it possible to construct a rating assessment of a complex and multifactorial economic object – the financial potential, using algorithms of systematization to multidimensional quantities. The authors present the stages of application of analytical procedures for assessing the dynamics of taxonomic indicators of financial potential as well as for constructing the rating of the suggested business entities. An innovative model of financial potential of forestry enterprises is proposed, which will allow to identify the complex of properties of an object as a basis for forming a set of analytical procedures for assessing its state. The obtained results of the analysis can serve as the basis for constructing a management strategy to optimize the financial potential of the enterprise.

Opis:

Rural development policies lately take an inter-sectoral area-based approach. This turn raises questions relating to governance on the one hand and issues relating to the participation of different sectors therein on the other. In this paper I present a case study from Germany, focussing on three area-based rural development funding programmes, two temporary pilot programmes and a mainstream scheme. The concept of regional governance is shown to play a crucial role in the implementation of pilot programmes, while mainstream policy only partly is affected. Forestry as a sector was found to only play a minor role in such processes of regional governance. This paper reveals sector – internal as well as – external causes of this phenomenon and closed with conclusions on how to (sector-internally and – externally) enhance forestry participation to area-based rural development programmes.

Grzyby entomopatogeniczne to niewielka grupa grzybów atakujących owady wywołujące choroby zakaźne – grzybice. Wykorzystuje się je w biologicznym zwalczaniu szkodników, ograniczając w ten sposób stosowanie środków owadobójczych. Grupa obejmuje szeroką gamę gatunków, dzięki czemu wykazują one dużą różnorodność biologiczną i ekologiczną, zapewniając wiele możliwości ich wykorzystania. W poniższym artykule dokonano przeglądu aktualnego stanu wiedzy na temat grzybów entomopatogenicznych i różnych możliwości ich wykorzystania w gospodarce leśnej, prezentując najskuteczniejsze gatunki grzybów w zwalczaniu wybranych szkodników upraw leśnych.
Entomopathogenic fungi are a small group of fungi that attack insects, causing contagious diseases – mycoses. They are used in biological pest management, therefore reducing the use of insecticides. The group includes a wide range of species, so that they show high biological and ecological diversity, providing many ways of using them. The following article provides an overview of the current state of knowledge on entomopathogenic fungi and various possibilities of their use in forest management, presenting the most effective species of fungi in the control of selected pests of forest crops.
