Subtropical forests are important carbon sinks and have a huge potential for mitigating climate change. However, few studies have developed biomass models to give robust estimates of subtropical forest aboveground and belowground biomass. Although wood density (WD) can greatly reduce the uncertainty in aboveground biomass (AGB) estimates in tropical forest, it has never been applied in other ec...

Under the auspices of the US Forest Service Forest Products Laboratory and the Coalition for Advanced Wood Structures (CAWS), the Southern Climatic Housing Research Team -a multidisciplinary group of wood scientists, architects, landscape architects, mechanical and civil engineers – is designing a research and demonstration house for the Southeastern United States on the campus of Mississippi S...

This paper presents conceptual framework of forest foods and food security link to forest resource management to well being. NWFPs studies in different areas, important species to Lao people’s livelihood, household uses and commercialization, nutrition study on forest foods, NWFPs research projects in the past and going on project and the concepts note of one activity to be implemented on enhan...

Background Aspen(Populus tremula) and birch (Betula pubescens) are the fast-growing trees successfully used for the aim of plantation forestry. These species have the great potential in Russia to meeting the need for paper, timber and other wood-based products. However, enhanced growth rate, decreased lignin content and herbicide resistance are the required properties of new trees for plantatio...

Editor’s note: In an effort to help automate the inspection for lumber defects, optical scanning systems are emerging as an alternative to the human eye. Although still in its infancy, scanning technology is being explored by machine companies and universities. The following article was excerpted from “Machine Vision Systems for Grading and Processing Hardwood Lumber, ” by Philip A. Araman and ...

11 A feasibility study of glulam was carried out in French Guiana using local wood species. The aim 12 was to determine gluing parameters affording satisfactory behaviour to manufactured glulam in 13 a tropical climate. 14 Three abundant wood species, with special properties, were selected for the study and 15 Resorcinol-Phenol-Formaldehyde resin was used for bonding. Three industrial parameter...

High-quality pallets are easier to repair and last longer. To obtain the high-quality parts necessary to build durable pallets requires grading and sorting by an automated inspection system. Ultrasonic sensing was selected for this application because 1) it is relatively inexpensive; 2) it can penetrate and characterize internal features of wood specimens; and 3) its effectiveness has been demo...

Policies are being developed worldwide to increase bioenergy production as a substitution for fossil fuel to mitigate fossil fuelderived carbon dioxide emissions, the main cause of anthropogenic global climate change4,5. However, the capacity for forest sector bioenergy production to offset carbon dioxide emissions is limited by fossil fuel emissions from this activity (harvest, transport, and ...

Sweden has just more than 23 million hectares of productive forest, which has been actively managed for more than 100 years. This has led to one of the recognized forest products exporting country. Despite the vital role of forests in providing forest products in sustaining various human needs, there is an increasing demand for the inclusion of ecosystem services in forest planning decision mak...

Forests perform multiple and interrelated social, economic and environmental functions and can be comprised among the ecosystems with the greatest biodiversity. The contribution of forests is multiple and renewable and, therefore, they constitute a most valuable natural resource. The benefits / values of forests can be divided into those of direct and indirect use. The first category includes t...
