Book Description
The eastern hardwood forest contains small diameter timber that is often of lower quality and lower value than larger sawtimber. This small diameter hardwood timber has traditionally been utilized for pulpwood, but it can also be used for lumber and residue production. In order to increase the utilization of this resource by sawmills, a number of analyses need to be conducted. These analyses include a resource analysis, yield analysis, economic analysis, and finally a market analysis. This report gives detailed instructions for conducting each of these analyses. The successful completion of these analyses will help hardwood lumber companies determine if using small diameter hardwood timber is a good decision for their company.

Book Description
The purpose of this study was to examine the feasibility of processing and marketing the hardwood bark and finewood residue materials generated by the primary wood using industries located within the project study area (an area encompassing all of Illinois and area fifty miles wide surrounding Illinois). The study (1970 through 1973) involved three separate phases of work. The first phase developed information regarding the sources of residue materials both with regard to the geographic distribution of the mills generating the residues and with regard to the quantities produced by the various types of mills within the project area. The data developed indicated that 71 of the saw mills considered to be large enough to justify debarker installations and the six pulp mills operating in the study area could have generated an estimated 1,125,000 cubic yards and finewood residue materials in 1970 if all the round wood processed had been debarked. The mills with debarkers Installed in 1970 generated about 528,000 cubic yards of residue bark and an additional 335,800 cubic yards of finewood residues (sawdust and shavings). The remaining indicated potential supply of residue materials (261,200 cubic yards) is the residue materials that could have been produced by those larger mills that had not installed debarking equipment at the time the study was made. The second phase of the project or marketing study developed information regarding the market project area when used only as mulches, soil conditioners, bedding, litter and for other closely related type uses. The eleven user-groups contacted in the marketing survey represented approximately 7,300 potential marketing outlets for these materials. This figure excludes the livestock producers. The eleven user-groups surveyed used and/or sold approximately 2,902,000 cubic yards of all types of mulching materiasl in 1971. It was estimated the twelfth user-group considered (all Commercial livestock producers) uses an additional 26,000,000 cubic yards of bedding and litter materials annually. By applying estimated replacement ratios of wood residue products for the various other types of materials now used and/or sold by these various user-groups, it appears a market potential of approximately 1,979,000 cubic yards of wood residue products could be developed in the marketing area. This indicates that potential markets in excess of the quantities of bark and wood residue generated by the primary wood using industries can be developed over the next five to seven years. The third phase of the study examined, through operational analysis procedures, the economic aspects of processing and distributing residue products from eight assumed processing sites to nine major marketing points within Illinois. The MPS/360 linear programming routine (6), a basic cost minimization procedure, was modified to develop a profit maximization model. The purpose was to determine what the optimum flow of the various types of residue products would be from the eight assumed processing points (including external sources) to the nine marketing points selected in the study area. Various spacial analyses were made wherein the objective functional elements of the matrix (production costs, transportation costs and product selling prices) as well as flow constraints were varied to demonstrate the sensitivity of optimum flow solutions to these variable cost and price elements. Spacial Analysis IV indicates all residue materials in the project area could be dispersed profitably if the average delivered prices of $11.88 per cubic yard for bagged mulches, $6.72 per cubic yard for bulk processed bark and $3.25 per cubic yard for bedding and litter prevail. Returns of approximately $5,500,000 would accrue to the primary wood processing firms participating in the production and distribution of these residue products, 34 percent of which would derive from sources outside the project area.

Book Description
This book is primarily a general text covering the whole sweep of the forest industries. The over-riding emphasis is on a clear, simple interpretation of the underlying science, demonstrating how such principles apply to processing operations. The book considers the broad question "what is wood?" by looking at the biology, chemistry and physics of wood structure. Wood quality is examined, and explanations are offered on how and why wood quality varies and the implications for processing. Finally, various "industrial processes" are reviewed and interpreted. All chapters have been written by specialists, but the presentation targets a generalist audience.

Book Description
1 Plantation forests and biodiversity: Oxymoron or opportunity? Forests form the natural vegetation over much of the Earth’s land, and they are critical for the survival of innumerable organisms. The ongoing loss of natural forests, which in some regions may have taken many millennia to develop, is one of the main reasons for the decline of biodiversity. Preventing the further destruction of forests and protecting species and ecosystems within forests have become central issues for environmental agencies, forest managers, and gove- ments. In this di?cult task science has an important role in informing policy and management as to how to go about this. So how do industrial and other pl- tation forests ?t into this? Plantation forests, comprised of rows of planted trees that may be destined for pulp or sawmills after only a few years of growth, appear to have little to c- tribute to the conservation of biodiversity. Yet there is more to this than meets the eye (of the casual observer), and there are indeed numerous opportunities, and often untapped potential, for biodiversity conservation in plantation forestry. With plantation forests expanding at a rate of approximately three million hectares per year, it is crucial to understand how plantations can make a positive contribution to biodiversity conservation and how the potentially negative impacts of this land use can be minimised. That is the topic of this book.

Book Description
In Fire in Sierra Nevada Forests, George Gruell examines the woodlands through repeat photography: rephotographing sites depicted in historical photographs to compare past vegetation to present. The book asks readers to study the evidence, then take an active part in current debates over prescribed fire, fuel buildup, logging, and the management of our national forests.
