This research was conducted in the west forest of Guilan, northern Iran. Data from various harvesting methods for 20 years were collected. Results showed that, productivity rate of round wood, pulp wood and fuel wood has had an upward trend, while rate of traditional products (lumber, sawn wood, charcoal, etc.) has had a downward trend. Production cost has been investigated in this research. Th...

Satellite remote sensing and numerical modelling are important tools to quantify trends in the environment across Canada. This paper describes methodology and initial results for the production of a new 1-km resolution map of waterbody fraction and 10-km resolution maps of forest cover type (hardwood/softwood) required as input parameters to these approaches. The waterbody fraction map is deriv...

J-FOR Journal of Science & Technology for Forest Products and Processes: VOL.1, NO.2, 2011 38 To a great extent, the design of large forest products facilities has been based on the assumptions of stable future wood costs and species mix. Mill design and wood supply are dealt with as separate, although connected, calculations. This is essentially an agricultural model in which supply is availab...

The classes of primary chemical products naturally produced by the combustion of forest fuels include: carbon dioxide, water, carbon monoxide, particulate matter, methane and nonmethane hydrocarbons, polynuclear aromatic hyrocarbons, nitrogen and sulfur oxides, aldehydes, free radicals, and inorganic elements. Pesticides are a class of secondary chemical byproducts of fires that have been of so...

The tissue industry constantly strives for improving the overall quality of paper, as customers pay more attention to special features when it comes a purchase decision between different products. As producers need optimize their processes and furnish mixtures keep production costs low, accurate fast methods are crucial characterization important properties. Here, we present method surface rega...

The Joseph William Gottstein Memorial trust Fund was established in 1971 as a national educational Trust for the benefit of Australia's forest products industries. The purpose of the fund is to create opportunities for selected persons to acquire knowledge which will promote the interests of Australian industries which use forest products for the production of sawn timber, plywood, composite wo...

A concern in the forestry literature is the perceived difference in production behavior between industrially owned forest land and land managed by nonindustrial private forest (NIPJ?) owners (Clawson; Binkley; USDA Forest Service). For instance, in the southern United States, a large share of the region’s softwood timber production (35%) comes from the relatively small share of forested acreage...

Conflicting perspectives on forests has for a long time challenged forest policy development in Sweden. Disagreements about forest futures create intractable deadlocks when stakeholders talk past each other. The purpose of this study is to move beyond this situation through the application of participatory backcasting. By comparing visions of the future forest among stakeholder groups, we highl...

We used a gravity model to investigate determinants of China’s pulp and paper products trade from 1995 to 2005. The results show that an importing country’s economy size, forest endowment, distance to China, exchange rate, and membership in Asia Pacific Economic Cooperation (APEC), plus China’s accession to the World Trade Organization (WTO) and its forest products policy change implemented in ...
