This paper describes an attempt to integrate the assessment of some non-wood forest products (NWFPs) in the framework of a standard forest inventory. The study is restricted mainly to medicinal and aromatic plants, i.e., herbal NWFPs, a group that has economic importance in the hill regions of Nepal. Several specific difficulties are discussed. They arise from the fact that a regular forest inv...

Symbiosis can be defined as a mutually beneficial relationship. Can there be a symbiotic relationship between forest products and the environment? If there is symbiosis of forest products and the environment, human beings are central to the process. Historically forests have always played a significant role in the human environment. At one end of the relationship, forests help provide the oxyge...

The forest sector represents a large source of income for Canadians. In 2013, the forest sector contributed $19.2 billion or 1.25% of Canada’s GDP [1]. Harvested wood products (HWPs), which are manufactured using wood harvested from forests, have also made headlines recently, with the world’s tallest wood building at 18 storeys having completed construction at the University of British Columbia...

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...

Carbon stocks in managed forests of Ontario, Canada, and in harvested wood products originated from these forests were estimated for 2010-2100. Simulations included four future forest harvesting scenarios based on historical harvesting levels (low, average, high, and maximum available) and a no-harvest scenario. In four harvesting scenarios, forest carbon stocks in Ontario's managed forest were...

Climate change mitigation benefits from the land sector are not being fully realised because of uncertainty and controversy about the role of native forest management. The dominant policy view, as stated in the IPCC's Fifth Assessment Report, is that sustainable forest harvesting yielding wood products, generates the largest mitigation benefit. We demonstrate that changing native forest managem...

wood and non-wood resources in the forests have occupied a very important place in human’s life, since the advent of history. and today, developing technology along with increasing needs enhance the importance of the other functions of forests, in parallel with wood production. both in the world and as well in turkey, one of the featured functions of forests is the production of non-woodforest ...

The different uses of wood result in a hierarchy of carbon and energy impacts that can be characterized by their efficiency in displacing carbon emissions and/or in displacing fossil energy imports, both being current national objectives. When waste wood is used for biofuels (forest or mill residuals and thinnings) fossil fuels and their emissions are reduced without significant land use change...

In wood trade, the supplier is the forest and the product is round wood. The quality, the quantity and value of wood depend heavily on the practices that are applied in the early stages of the supply chain. Current methods of the the productive capacity of forests, the annual consumption of wood and wood products, both from natural and technical forests and also from imports are presented. The ...
