Over the last five years forest products other than timber-based products have received a great deal of attention. The markets for medicinal plants that are collected from the forests are growing rapidly. Some reports suggest this segment of the non-timber forest products industry is expanding faster than the timber-based industry. Plants used for their therapeutic value are marketed either as ...

Forest inventory and harvest data from life-cycle inventory and life-cycle assessment for the forest resources of the Inland Northwest region covering Idaho, Montana, and eastern Washington were used to estimate the impacts of management action on the full suite of carbon accounts that can accrue from forest management. The carbon accounts include the forest, wood products, the benefit gained f...

The 21”’ century continues a trend of rapid growth in both international trade of forest products and a concern for forests. These two trends are connected. Forces causing trade growth are linked to the loss of native forest resources in some countries and the accumulation of nonnative forest resources in other countries. Factors increasing trade include relaxation of trade barriers, income gro...

Large quantities of forest products are disposed of in landfills annually. The fate of this vast pool of carbon is important since carbon sequestration and the generation of landfill gases have important implications for global warming. Published estimates of methane yields were used to estimate the amount of carbon released into the atmosphere from landfilled forest products. These calculation...

machinability. Abstract Flakes 3 Inches along the grain. 3/8-inch wide, and 0.02 inch thick were machined from the taproots (with 6inch-high stump) and second logs at eight 31-year-old slash pines. Specific gravity (O.D. weight, green volume) of Items averaged 0.52; rootwood averaged 0.43 and decreased sharply with depth below ground. Forty-four-lb./cu. ft. structural-type particleboards were p...
