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.

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.
