Abstract In this study, the effect of acetylation and coating with boiled linseed oil was evaluated concerning the photodegradation of common hornbeam wood (Carpinus betulus L.). To measure colour stability, a 10-month-long outdoor weather resistance test without soil contact was performed as well as artificial aging using a 200 hour mercury-vapour lamp irradiation test. The measurements were done on hornbeam, acetylated hornbeam, boiled linseed oil-treated hornbeam, and acetylated and boiled linseed oil-treated hornbeam samples. The control and treated samples’ colour change was determined by comparing them to the original colour in all cases. The photodegradation process was examined with Fourier Transform Infrared (FTIR) spectra. Acetylated hornbeam was less prone to crack, but the modification did not hinder the fading and greying caused by UV irradiation. Coating the samples with boiled linseed oil decreased the rate of colour change and cracking. The photodegradation of lignin was confirmed by the FTIR spectra.

Abstract The primary research aim was to explore the possibilities of transferring relevant data from information systems and databases required for practical environmental impact assessment. The necessary and adequate data content of environmental impact studies were defined according to legal regulations, expert recommendations as well as available impact studies. Furthermore, the data content of information systems pertinent to environmental impact analysis were investigated in view of data transmission. Disposing of the primary data required for impact studies, the classification of environmental objects (object class, object group, object type) was performed. Based on the latter, a pattern system design was completed; in the course of developing this, we defined the individual system overlays in the theoretical model, then assigned properties of the individual object types in the database model.

Abstract Medium density fiberboards are widely produced and used in Europe. The main raw materials used in Hungary are beech (Fagus sylvatica), hornbeam (Carpinus betulus), poplar (Populus spp.) and pine (Pinus spp.). Governmental subsidizing of biomass for power plants has created economic pressure and a shortage of wood prompting a major producer of energy grass to initialize a project to examine the possibility for the production of MDF from energy grass “Szarvasi-1” (Elymus elongatus (Agropyron elongatum) cv. Szarvasi-1). Prior to this, no research results on the experimental production of MDF from energy grass had been published. In our research study, energy grass was defibrated and MDF boards were produced with the use of different adhesives. Standard tests were completed to evaluate the suitability of this alternate raw material in MDF production. The best result was achieved with phenol formaldehyde (PF) adhesive.

Abstract Due to their huge benefits when compared to invasive or destructive techniques, the use of non-destructive approaches is continuously increasing in many fields. The visual assessment method is commonly applied in tree inspection, but it has limitations. Investigations using appropriate nondestructive instruments can well complement visual tree inspection. This paper is a short overview that describes non-destructive techniques for evaluating the load-bearing capacity of individual trees’ root systems. The techniques used are acoustic root detection and the pulling test. Safety factors were also calculated to provide a hazard assessment.

Abstract This paper describes a methodology for experimental research of the change in the temperature and humidity of the air processing medium and also in the temperature at 4 points of the longitudinal section of logs during freezing. The suggested methodology is used to research the change in the mentioned parameters of poplar logs with diameters of 240 mm, lengths of 480 mm and moisture content above the hygroscopic range during 50 h of freezing in a freezer at a temperature of about -30 °C. The automatic measurement and recording of the parameters is carried out with the help of Data Logger type HygrologNT3 produced by the Swiss firm ROTRONIC. The precise instrumentation allowed, for the first time ever, the measuring of the impact the latent heat released by the free water on the log had on the warming up of the wood during water crystallization in the logs.

Abstract During a regular survey of declining forests in 2011, sudden dieback symptoms were observed on scattered wild cherry trees (Prunus avium) in a mixed deciduous forest stand, located in the flood plain area of the Rába River, in northwest Hungary. In this study, we correlated both soil conditions and presence of Phytophthora spp. to dieback of cherry trees. Two Phytophthora species, P. polonica and P. plurivora, were isolated from the rhizosphere soil of the dying trees. By contrast, only P. polonica was recovered from the necrotic tissues of symptomatic roots. Stem and root inoculation tests on cherry seedlings showed pathogenicity of both species, although P. polonica proved to be more virulent. This is the first report of natural infections of P. polonica.

Abstract It is well known that worldwide deforestation has a negative impact on the global environment. Forests play an important role in producing oxygen as well as retaining gases that create the greenhouse effect. Forests primarily absorb carbon dioxide, the major air pollutant released by the industrial activities. Energy production is the major source of environmental contamination. In addition to reducing CO2 emissions, another issue this industrial sector must tackle is to decrease the use of fossil fuels by substituting them with renewable, environmentally friendly energy sources. One of the answers to these challenges is the utilization of biomass as energy sources. However, biomass-based fuels include short bolts, split round-wood, pulpwood, bark and by-products of sawmilling, which are the raw materials for the wood-based panel industry as well.Wood utilization of the forest products industry has a major impact on the delayed release of carbon dioxide stored in the wood. All over the world, just as in Hungary, the wood-based panel industry mainly uses low quality wood resources and turns them into value added products. The elongation of the life cycle of low quality wood materials decreases CO2 emissions, thus significantly contributing to environmental protection. Furthermore, it is assumed that raw material demand of the wood-based panel industry could be satisfied by focusing on sustainable forest management and well-planned reforestation. Additionally, special energy-plantations may provide extra wood resources, while waste and other non-usable parts of trees contribute to the effective and economic operation of biomass utilizing power-plants. This paper summarizes the current situation of the Hungarian wood-based panel industry and discusses the effects of the panel manufacturing processes on the environment. Also, it outlines the possible future of this important segment of the forest products industry.

Abstract Beside sustainable development, vulnerability might be the most frequently used expression in environmental studies. Vulnerability depends on the intensity of the impacts on a natural or social system as well as on its adaptive capacity. Appropriate adaptation warrants successful survival of the system even under high impact, when its vulnerability is significantly reduced; therefore, measuring adaptive capacity should have an established place in the methodology of impact – adaptation – vulnerability research. The main problem is to find relevant data that are required to establish indicators. In our study, the focus was laid on measuring adaptive capacity within vulnerability research, and on identifying possibilities for accurate calculation of adaptation. An attempt was made to determine the adaptive capacity to droughts in the micro-regions of Zala County. It could be established that the adaptive capacity of the population in the rural areas of Zala County to the expected increase in drought frequency is very low, which can be primarily explained by the lack of knowledge about adaptive agriculture.

Abstract The bondability of beech (Fagus sylvatica L.) wood with a one-component polyurethane (1K PUR) structural (load-bearing) adhesive has been investigated at the Simonyi Károly Faculty at the University of West Hungary. Our trial is considered a preliminary investigation in order to set the convenient parameters of bonding for the structural gluing of beech wood. Wood samples were characterized by their oven dry density, and the surfaces to be bonded were characterized by their surface roughness and surface tension after machining. Based on our measurements, we have made a suggestion on the value of the ensemble of open time, applied quantity and pressure, pressing time, and surface preparation/surface roughness parameters which result in good bonding and a shear strength higher than 10 N/mm2. Furthermore, we investigated the penetration of the adhesive into the surface and state that one-sided adhesive application results in differing levels of penetration. In order to check the suitability of beech wood for glued laminated timber production, further investigations according to EN standards are necessary. Based upon the considerations noted above, delamination tests are already under evaluation.

Abstract In European countries, current forest use aims to enhance goods and services supplied by forest ecosystems, taking into account the multiple needs and interests of society through a participatory process. A successful participatory process requires a thorough analysis of stakeholders’ perceptions and preferences. The aim of this paper is to investigate the differences between stakeholders’ perceived influence and real power in forest management. A questionnaire survey was carried out among 51 forest stakeholders in a case study in the Italian Alps. Perceived influence was measured by asking stakeholders to rate on a 5-point scale the extent to which they can influence forest management issues. Real power was analyzed using social network analysis (SNA), investigating the relationships that stakeholders have with each other in the network. Real power was measured using a Freeman’s degree centrality measure, which focuses on the direct ties coming in and out for each stakeholder. The results show that public administration is the category of stakeholders with the most power in all forest management issues, while the actors of the tourism sector are in a marginal position. In addition, the results of the study suggest that in many cases stakeholders have a distorted perception of their own power.
