Abstract:

Stiffness is considered one of the most important structural properties for sawn timber used in buildings and laminated structures including mass timber elements. There is great potential to use plantation Eucalyptus timber for structural applications, and the successful development of a plantation timber supply chain for structural products will depend on the accurate selection and grading of the resource. In this study we aimed to investigate the suitability of non-destructive testing (NDT) to improve selection and grading of sawn boards sourced from a young E. nitens plantation. We studied 268 sawn boards traced from the tree through to final processing stages. We found high and positive correlations between stiffness (measured as dynamic modulus of elasticity) tested at each board processing stage through acoustic wave velocity (AWV) and the static board modulus of elasticity measured through mechanical testing on dressed boards. Position of the board in the stem and sawn board processing treatment significantly impacted board modulus of elasticity, indicating that early selection of logs would allow larger yield of stiffer boards. We investigated the grading of boards through the traditional Australian Standards using a visual-grading system and through AWV, finding a classification error of 82.5% and 45.2%, respectively. We developed a linear model which was used to re-classify the boards, obtaining a smaller classification error, including fewer boards being over-graded. Our results demonstrate that AWV can be used as an early selection method for structural boards and can also be employed to satisfactorily grade E. nitens plantation boards to be used in building structures and as elements of mass timber.

Abstract:

Changes in forestry practices in the United States have been dramatic over the past decade. These changes have been brought about largely through government regulations promulgated in response to pressure from environmental and other groups at both federal and state levels. Historically, the federal government has taken leadership in forest stewardship, though some states have demonstrated strong initiatives over the years. Two separate, but intertwined, factors combined to alter the practice of forestry over much of the United States. There were the interactive consequences of obedience to national environmental laws, passed in the 1960s and 1970s, and a rising environmental consciousness among the majority of the minority of the citizenry who care about natural resource issues. Rising public concern was focussed in challenges in the federal courts to government forest management activities, and in terms of public relations campaigns using lobbying, demonstrations, and manipulation of the mass media. In July of 1993, President Clinton selected an option for management of federal forests in the Pacific Northwest section of the United States that dedicated 9.28 million acres (3.75 million hectares) of federal forests to reserves to be managed for late-successional/old-growth ecosystem function and riparian/fisheries protection. This reduced the anticipated timber sale levels from the 2.4 billion board feet (5.7 million m3) cut annually in 1990-1992, to 1.2 billion board feet (2.8 million m3) projected for 1994. There is an ongoing shift in management philosophy toward "ecosystem management" of forested lands with increasing attention to aesthetics and more benign environmental effects of timber management.

Abstract:

Using bamboo particle board as a wall divider, a furniture component, or an automotive component with a sound absorber function may be a viable option for architects and engineers seeking to achieve desired acoustical qualities, including noise reduction. However, there is still a dearth of research on the effect of particle board finishing and coatings on acoustical sound absorption and noise reduction qualities. This study, therefore, aims to determine the surface characteristics and acoustical properties of bamboo particle board, coated with polyurethane (PU). The single-layer homogeneous particle boards were constructed using particles classified as fine and coarse with two different board densities, and coated with a high-quality PU lacquer. This study found that the coating treatment of 0.3 mm 0.6 mm succeeded to significantly decrease surface roughness, as well as thickness, swelling, and water absorption, with the thickness coating as a dominant factor compared with board density and board particle size. Adding a PU coating increases sound absorption performance at low frequencies, but significantly reduces acoustical properties at high frequencies. The increase of particle board density leads to the decrease in noise reduction coefficient capability. Results obtained from this study are useful to determine the optimal coating thickness in terms of evaluating acoustical panel products.

Abstract:

The Eastern Ontario Model Forest was created in 1992 as a grassroots organization, representing a wide diversity of players interested in Eastern Ontario's extensive privately-owned forested and agricultural lands. An initial series of intensive meetings eventually led to the adoption of an innovative board structure with strong representation from the membership at large including seats for industry, First Nations and provincial government and a constitution based on consensual decision-making. The Eastern Ontario Model Forest recognized the knowledge it would gain in developing sustainable forestry activities. From the outset, it clearly expressed in its goals and objectives a desire to participate in global initiatives for sustainable forestry, such as the development of criteria and indicators. Simultaneously, the Eastern Ontario Model Forest sought to become involved, again at the grassroots level, with a similar Model Forest outside of Canada. It established a unique twinning relationship with the Calakmul Model Forest in Mexico to enhance the flow of knowledge and experience between people faced with similar challenges. The experience gained from the Eastern Ontario Model Forest members' participation in local, national, global and back down to local Mexican forestry issues has helped improve the understanding and application of sustainable forestry principles in their own backyards. Simultaneously, the Eastern Ontario Model Forest expects that its own contributions in these same flora will help further the application of sustainable forestry outside the Eastern Ontario Model Forest boundaries. Key words: Eastern Ontario Model Forest, community forestry, multi-stakeholder decision making

Abstract:

A general overview of the school system in Finland is provided as background to a detailed description of forestry education in that country. Vocational and technical forestry education is organized and conducted by the National Board of Vocational Education. Numerous occupational diploma programs are offered at 30 forestry schools and colleges, including programs for forest workers, forest machine operators and mechanics, forest technicians, sawmill technicians, wood-based panels technicians, forest engineers, and forest-industry engineers, Short courses and refresher courses are also provided for more than 30 000 people annually. Three universities offer higher degrees in forestry: the University of Helsinki, the University of Joensuu, and the Helsinki University of Technology. International forestry is an important element of forestry education. It is addressed through a marketing degree program that emphasizes international commerce through the training of students from developing countries and through foreign-exchange programs for students, teachers and researchers. Examination of the organization and teaching of forestry subjects in Finland suggests ways in which Canadian forestry education might be improved to meet the future needs of an increasingly technical forestry sector.

Abstract:

In this research the spruce plywood board and combined spruce-beech plywood board were prepared in laboratory conditions using two levels of processing pressure. The bending properties in perpendicular and longitudinal direction were measured and compressibility and density were specified. Considering the obtained results, there was found an overall increase of the bending properties in spruce plywood manufactured by the higher pressure and a decline of properties perpendicular to the grain in combined spruce-beech plywood board. On the other hand, combined spruce-beech plywood boards produced by the common processing pressure performed better than both types of spruce plywood.

Abstract:

The use of herbicides in forestry in British Columbia is regulated by both federal and provincial governments. The Ministry of Environment, Pesticide Control Branch, through the B.C. Pesticide Control Act, controls the handling, selling and application of pesticides once they have been registered by the federal government. A herbicide treatment must have a Pesticide Application Permit, which anyone may appeal through the BC Environmental Appeal Board. Herbicide use in forestry must be based on sound silvicultural judgment. Potential means by which 2,4-D and Roundup may enter the aquatic environment are reviewed. Methods of avoiding this during a forestry herbicide treatment are discussed.

Abstract:

Deep processing of wood raw materials is the main field of its use. The forecast of timber industry development provides deep chemical processing and start-up of board materials production. In the available forest reserves the share of pulpwood and forestry engineering raw materials is up to 13 per cent. Some measures will contribute to settle the problems of increasing wood raw material complex use and green production of board wood composite materials. They include the improvement of existing technologies and implementation of progressive technologies and systems increasing the volume and quality of board output. One of the main directions will be the maximum possible use of all components of raw materials, when some production wastes are the raw material for the manufacture of new products. This will provide the balance in efficient environmental management. The priority will be given to creation of a relatively closed cycle of wood resources use. Particularly promising in achieving a balance of economic and environmental interests of society will be obtaining of cheap boards capable to be not worse than solid wood with minimum cost of natural resources and preservation of individual properties of each component.

Abstract:

Wood-cement panels are becoming increasingly widely used as prefabricated building materials. In order to increase the use of renewable resources as materials for industrial applications, the use of alternative plant fibres has been gaining interest. Additionally, it is assumed that new or better board properties can be achieved due to the different chemical and mechanical properties of such alternative sources of fibres. In south-eastern Spain, the Canary Islands palm (Phoenix canariensis) is widely used in urban landscaping. Plantations attacked by red palm weevils generate abundant plant waste that must be shredded and taken to authorised landfills. This paper discusses the use of particles of Canary Islands palm for manufacturing fibre panels containing 20% cement in relation to the weight of the particles, using different proportions of starch as a plasticiser. A pressure of 2.6 MPa and a temperature of 100 °C were used in their production. Density, thickness swelling, water absorption, internal bonding strength, modulus of rupture (MOR), modulus of elasticity (MOE), and thermal conductivity were studied. The mechanical tests showed that the MOR and MOE values increased with longer setting times, meaning that the palm particles were able to tolerate the alkalinity of the cement. The board with 5% starch had a MOR of 15.76 N·mm−2 and a MOE of 1.872 N·mm−2 after 28 days. The boards with thicknesses of 6.7 mm had a mean thermal conductivity of 0.054 W·m−1·K−1. These boards achieved good mechanical properties and could be used for general use and as a thermal insulation material in building construction.

Full text

Abstract:

An important outcome of social learning in the context of natural resource management is the potential for collective action—actions taken by a group of people that are the result of finding shared or common interest. Evidence of the relationship between collective action and social learning is beginning to emerge in the natural resource management literature in areas such as community forestry and participatory irrigation, but empirical evidence is sparse. Using a qualitative inquiry and research design involving a case study of the Wet’zinkw’a Community Forest Corporation, this paper presents research that examined the relationships between collective action and social learning through community forest management. Our findings show strong evidence of collective action outcomes on the part of board members responsible for the community forest, such as establishing a legacy fund, adding value to logs, protecting First Nations cultural values, and hiring locally. Our data also reveal that the actions taken by board members were encouraged through social learning that was related to acquiring (new) knowledge, developing an improved/deeper understanding, and building relationships. However, we found limited opportunities for community forest partners and the general public to learn and contribute to collective action outcomes since the actions taken and associated learning occurred mainly among board members.

Abstract This article is an attempt to draw attention to the differentiation used to conserve endangered and protected species of flora in an area that is administered by the management board of the State Forests. I also draw attention to areas of insufficient knowledge of this subject-matter. A detailed inventory of endangered and protected species of flora for the purpose of planning in forestry would be very useful in light of laws related to nature conservation and the problem of preserving biological diversity. Research in the forest administration region of Sokołowice indicates that almost 2/3 (65.16%) of all sites harbouring endangered and protected species of flora are new (previously undocumented), despite the existence of numerous protected areas – this fact indicates that there are great research possibilities in this field. The main conclusion from this research confirms that multifunctional forestry in Poland will provide the greatest opportunity to preserve the widespread and numerous sites holding endangered and protected species of flora in economically important forests.

Abstract:

Abstract This research introduces a framework for tracking the state of the forest industry and relative competitiveness at the local level and applies it to the state of Georgia. Key insights highlight how localized forestry and forest industry profiles indicate where wood demand and suppliesare in and out of balance on an annual basis. Alternately, localized profiles that emphasize physiographic regions may not correspond well with traditional wood procurement areas. More importantly, ongoing tracking of wood supply viability and competitive analysis must distinguish between timber markets (stumpage, forest inventories and removals, and growth) and end product commodity markets (lumber, pulp, oriented strand board, and plywood). Mills, like forests, are not uniformly distributed throughout a state, whether measured by size, type, or end product. Tracking the forest industry in a localized, annual manner can support ongoing planning, investment, and policymaking activities in a targeted and efficient manner.

Abstract:

The effects of fiberglass plaster mesh (FPM) as reinforcement on some physical and mechanical properties of cement bonded particleboard (CBP) were examined. Experimental CBP with and without FPM were manufactured in laboratory conditions using wood particles, cement, tap water and chemical accelerators. Two plies of FPM, manufactured using fiberglass and polyester resin, were laid within the experimental CBP. The target density of CBP was 1300 kg/m3 in the study. Three different types of chemical accelerators (CaCl2, KCl, DARASET ® 580) were used in the experiments. Properties of CBP evaluated include 2- and 24-hour - thickness swelling (TS), 2- and 24-hour - water absorption (WA) and bending stiffness (MOE) and strength (MOR). The results indicate that all the board properties tested were significantly improved by FPM application. The average MOE values of the CBP boards with FPM was two times higher than those of the boards without FPM. Dimensional stability and MOR of the CBP boards were also significantly improved with the use of FPM. FPM can be used to improve inferior properties of the CBP, so as to make it more compatible with other wood based construction materials.

Abstract:

The effects of some polymer additives, also called super plasticizers, on selected physical and mechanical properties of cement bonded particle board were investigated. Two different kinds of poly carboxylic ether (PF300, DX40) and a melamine based polymer (300M) were added to the wood cement mixture. The ratios of polymer additives to the wood cement mixture were 1%, 1.2% and 1.4%. Cement bonded particleboards were manufactured with wood/cement (w/w) ratio of 1:3; target density of 1300 kg.m-3, and CaCl2 content of 5%. The cement bonded particleboards were tested for water absorption (2 and 24 hour), thickness swelling (2 and 24 hour), bending stiffness and strength and internal bond strength. Results of the study showed that most of the polymer addition decreased water absorption and thickness swelling of the boards. Replacement of cement with polymers increased internal bond strength and bending stiffness of the boards while bending strength was slightly reduced. Use of small amount of super plasticizers significantly improves most of the board properties.

The purpose of this research was to analyze the performance (wear resistance, surface roughness, chip formation, and noise level) of AlCrN, TiN, and TiAlN coated tungsten carbides in cutting composite boards. The composite boards of wood plastic composite, laminated veneer lumber, andorientedstrand board were cut by the coated tungsten carbide tools in a computer numerical control router. The results show that the differences in structure among the composite boards resulted in the difference in clearance wear, chip formation, surface roughness, and noise level phenomenon. The abrasive materials in wood plastic composite generated the highest clearance wear on the coated carbide tools tested. TiAlN coated carbide tool provided better wear resistance, smoother composite boards surfaces, and lower noise levels.

Abstract:

Forest conversion has been identified as one of the several bottlenecks affecting upon the major infrastructure projects in Nepal, especially in the energy and transport sectors. Nepal’s policy requires at least 40% of its land cover under forest. This means if any forest land is converted to non-forest land, it must be compensated with an equivalent area, preferably in the similar ecotype in the nation. In addition, a specified number of trees must be planted for the number of trees felled in the project site, and the site must be managed and protected for five years by the developers. These provisions have led to growing resentment between the developers and the Ministry of Forests and Soil Conservation (MFSC), leading to delay in providing forest lands for infrastructure projects. With a view to develop mechanisms for the government to rapidly provide forest land for nationally important infrastructure projects, the Government databases were examined to analyze the forests handed over to the developers for non-forestry uses. The data showed that a total of 14,028.4 ha of forest area were handed over to the developers for non-forestry uses until the end of 2015. On an average, 263.8 ha forest area was found to be handed over to the developers between the period of 2010–2013. However, there is a declining trend of forest handed over for non-forestry purposes in the recent years. The decline could be due to the strict enforcement of the legal provision which limits the conversion of forest areas to non-forest areas except in the case of the “national priority projects”. It has been recommended that the conversion of forest for infrastructure development should be examined with a holistic perspective by taking all the related components of forest conversion into consideration, from providing forest land for replacement planting. It is recommended that the Forest Product Development Board (FPDB), a parastatal organization under the MFSC, should be entrusted with the work of plantation related to forest conversion. The fund for this work should flow directly from the developers to the FPDB. The possibility of forming a land bank to facilitate the work of the FPDB is also recommended.Banko Janakari, Vol. 27, No. 1, Page: 60-64

Abstract:

Veneering of particleboard with ABS foil and natural oak veneer was performed using polyglycerol- and sucrose-based polyurethane adhesives. Bonding strength between veneer and underlying board was determined according to EN 312 standard. Developed adhesive formulations exhibited bonding strengths between coating material and underlying board exceeding the surface soundness of particleboard (cohesive failure between 50 % and 100 %). Higher adhesion was found for natural oak veneers. Reactivity of the studied adhesives was comparable to those for commercial adhesives used in furniture industry. It has been demonstrated that biobased polyols can be considered environmentally benign and efficient components of polyurethane adhesives for furniture industry.

Abstract:

The research consisted in testing Polish sawn timber dedicated for construction applications made of pines (Pinus sylvestris L.) that grew in the Silesian Forestry Region, taking into account three parts of the log: butt, middle and top. The boards had the same cross section, a nominal thickness of 40 mm and width of 138 mm, typical for Polish structural timber. The mean nominal length of the boards under research amounted to 3500 mm. Each set was composed of 70 boards. Before the tests, boards were dried in an industrial drier until reaching the moisture content of 12%, and they were planed on 4 sides. First of all, the sawn timber was graded into strength classes, and their dynamic modulus of elasticity (MOE_dyn) was tested with a non-destructive method, with the use of a portable MTG device. The next step consisted in a bending test with four points of support, according to the EN 408 standard, and with the use of the TiraTest 2300 machine, in order to determine the global modulus of elasticity (MOE_EN-408) and the static bending strength, also referred to as modulus of rupture (MOR). Finally, the average growth ring width was determined for each board (PN-D-94021), as well as wood density according to EN-408. The hereby paper presents the test results for all the tested sawn timber boards, taking into account the part of log that each board came from: butt, middle or top. The hereby paper presents the influence of density on the mechanical properties of wood, taking into account the location on the round timber. The analysis does not include the influence of the width of annual growth rings and the proportion of latewood on the wood properties under research.

Abstract:

The Native peoples of Alaska used wood for fuel, for the construction of shelters, and for a variety of implements. Explorers, fur traders, gold miners, and settlers also relied on Alaska's forest resource. The early 20th century saw the creation of the Tongass and Chugach National Forests in coastal Alaska, where large-scale harvesting began shortly after World War II. By 1955, two 50-year contracts had been signed, committing 13 billion board feet of sawlogs and pulpwood. The commercial forest land base in Alaska has been dramatically reduced by a variety of legislative acts, including the Statehood Act of 1959 and the Alaska National Interest Lands Conservation Act of 1980. Key words: forest history, Alaska, aboriginal use of forests, fuelwood, stemwheeled riverboats, gold mining, land classification, National Forests, Alaska Native Claims Settlement Act, Alaska National Interest Lands Conservation Act
