There are two competing hypotheses about the structure and dynamics of primeval forests in lowland Europe: the high-forest and the wood-pasture hypotheses, both of which influence current European forest conservation policies. In a recent study using pollen-analytical data from across lowland Europe, Mitchell provides support for rejecting the wood-pasture hypothesis. His study is important for...

One way to use the timber resources of our country more efficiently is to convert the refuse from logging and manufacturing operations into food. Research at the Forest Products Laboratory therefore is aimed in part at the conversion of wood to sugar solutions, which have been tested as livestock feed by several agricultural experiment stations. The investigations indicate that w^ood wastes can...

Resource sustainability requires a thorough understanding of the influence of forest management programs on the conservation of genetic diversity in tree populations. To observe how differences in forest management affect the genetic structure of Fagus orientalis Lipsky (oriental beech), we evaluated thirteen beech sites across Hyrcanian forests, based on six microsatellite loci. Significant di...

This study adds to the scientific literature dealing with climate change mitigation implications of wood substitution. Its main contribution rests modelling approach. By fully integrating forest resource and wood-product markets in quantitative scenario analysis, we account for international trade products as well impacts on EU forests forest-based sector employment an increased uptake wood-bas...

Chromated copper arsenate (CCA) treated wood has been used extensively in outdoor applications, ranging from fence posts to decking and wood foundations. CCA treatment provides long-term protection for wood because chemical reactions that take place during treatment fix the preservative elements in the wood. However, varying amounts of CCA have been reported to leach from the wood (Lebow 1996)....

This compendium provides extensions to the research first reported in the December 2005 Wood and Fiber Science Special Issue (WFS 2005) devoted to CORRIM’s Reports on Environmental Performance of Wood Building Materials. The Consortium for Research on Renewable Industrial Materials (CORRIM) is a nonprofit research consortium made up of 15 research institutions dedicated to developing comprehens...

Saproxylic insects play an important part in decomposing dead wood in healthy forest ecosystems, but little is known about their role in the aftermath of large-scale forest mortality caused by pest insect outbreaks. We used window traps to study short-term changes in the abundance and community structure of saproxylic beetles following extensive mortality of mountain birch in sub-arctic norther...

Logging industry is a fast-growing business regardless of the many risks involved. The procedures used to harvest wood are tree-length, full-length and cut-to-length logging. Choosing one over the other is simply a matter of choice since there are advantages and disadvantages with each of the various methods. The removal of too many trees from the forest can cause environmental hazards as well ...
