The need for additional sources of energy and raw material in the forest products industry enhances the opportunity to improve timber utilization by reducing logging residue. This is particularly true on the Pacific Coast where some 14 million tons of logging residue accumulate each year and where some 3 million tons of unused bark create a disposal problem at mills. The need to replace natural gas and oil to generate process steam or for drying with hot gases has given impetus to improved wood and bark combustion to provide needed energy without violating air quality standards. Cylindrical furnaces burning finely ground (minus 1/8 inch) bark or wood are being installed for lumber and veneer drying. New emission control systems and predriers are being adapted to fire large furnaces with wood or bark. The projected annual growth rate of 5 percent in U.S. and world pulp production has focused attention on forest residues as a source of fiber. Recent increases in chip prices help offset the high cost of logging residue, particularly if former disposal costs are credited to residue removal. Changes in timber sale procedures to facilitate more complete timber utilization are considered essential. Such proposed changes as negotiated lump sum sales, service contracts, and compound contracts are described briefly to indicate types of sale modifications that have been proposed. In summary, more complete timber utilization on the Pacific Coast may: (1) Add substantially to the available raw material supply8.4 million tons additional raw, (2) Add another energy source to that currently available as mill residue4.0 million bone-dry tons for fuel annually. (3) Protect thin soils by restricting or eliminating the amount of slash burning required. (4) Decrease air pollution by reducing the required amount of slash burning. (5) Reduce the debris that could interfere with streamflow and affect water quality. (6) Improve scenic values by reducing visible debris. (7) Improve recreational opportunities by providing easier access and a more acceptable environment. (8) Reduce public criticism of land management policies and much of the basis for public pressure to restrict clearcutting.

In this thoughtful collection of essays edited by Debra J. Salazar and Donald K. Alper, forest policy in the U.S. Pacific Northwest and British Columbia is examined in a binational context. While US and Canadian forest policy and forest management approaches differ, the two countries face similar challenges and conflicts. Contributors discuss the evolution of forest exploitation, the response of timber companies to U.S. federal environmental regulations, sovereignty for First Nations communities, and the reshaping of the political economy of forests by global forces on both sides of the border. Groups usually ignored in the forest policy debate -- such as First Nations peoples, workers in the emerging non-forest economy, and citizen activists -- are also given voice in this fascinating compilation.

Results are reported of a preliminary investigation of feasibility of using wood residue to meet energy and raw material needs in the Pacific Coast States. Magnitude of needs was examined and volume of logging-residue and unused mill residue was estimated. Costs of obtaining and preprocessing logging residue for energy and pulp and particle board raw material were estimated and compared with selling values of mill residue fuel, pulp chips, and particle board. Marginally feasible energy use seemed best suited for inplant steam and power production by the wood industry, Although raw material selling values make wood residue use for products more attractive than for electric power generation, even these returns are seldom sufficient to meet the high costs of delivering logging residue for such use alone. Production of higher valued products or public absorption of extra costs of utilization can make these residue management alternatives more feasible.

The forest manager must balance all the interacting and often conflicting factors influencing residue management and decide on the best course of action. He needs to determine optimum volume, size, and arrangement of residues to leave on an area after logging, then to select the harvesting methods and residue management alternatives that best provide these conditions. Cramer (1974) summarized environmental effects of forest residues management for major forest types in the Pacific Northwest, but types of treatment were not listed and only minor attention was given to hemlock-spruce forests. Residue management guidelines have been prepared for Oregon and Washington (Pierovich et al. 1975) but the hemlock-spruce type is not discussed as a separate entity. Alaska is not included in either report. This report provides a detailed look at residue management throughout the north Pacific coastal fog belt, including Oregon, Washington, British Columbia, and Alaska. The approach is a general look at forest residues as part of the ecosystem, then a closer look at dead and decaying material after logging, considering fire hazard and the silvicultural, physical, chemical, and esthetic effects of this material. Residue treatments are described, evaluated, and recommended. The report is intended to provide an improved scientific framework for management decisions. The coastal environment is more moist than other parts of the Pacific Northwest. Generally, fire danger is low and the need for residue treatment to reduce fire hazard is limited to special situations. Northward into Alaska, increasing summer precipitation relegates fire danger to a subordinate management problem. Hemlock-spruce residue volumes may range up to 250 tons per acre (560 metric tons per hectare) when an old-growth timber stand is defective and has a high proportion of western red cedar, but volumes may be less than 50 tons per acre (112 metric tons per ha) with more complete utilization of sound young timber. The trend is to less residue volume as defective timber is replaced by vigorous young stands and utilization improves. Residues often dominate the post-logging environment and are a major factor influencing forest regeneration. Fresh residue intercepts natural seed fall or aerially sown seed and prevents seedling establishment; but later, as it decays and with moisture present, it becomes a suitable seed bed for hemlock and spruce. Advance regeneration, usually hemlock, grows on decaying residue material and almost invariably is intermixed with fresh logging residue. Its fate is determined by residue treatment. When residue treatments expose mineral soil, they influence species composition favoring several species. These ecological relationships between forest residues and conifer seedlings can be used by forest managers to influence density and species composition of the new timber stand. A common problem in hemlock-spruce is too many seedlings. When advance regeneration is prolific, harvesting plans and residue treatments should be designed to destroy some of the seedlings. Overstocking with post-logging regeneration can be reduced if the logging operation is planned so that fresh slash covers an appropriate portion of suitable seed beds. In special situations, individual factors carry heavy weight in residue management decisions. For soils with high erosion potential, a protective mantle of organic material should be left. At least the small residue material should be left on nutrient-deficient soils to add to the nutrient capital. Residue should be kept out of stream channels. In Oregon and Washington, broadcast burning of residues in heavy brush areas helps to control the brush and open up the area for planting. Mistletoe-infested seedlings should be classed as residue and destroyed as part of disease control programs. Special attention should be given to residue management in recreation and scenic areas. Large, continuous areas of logging slash should be avoided because of fire hazard. Smoke management plans should be followed. Treatments are needed when residue volume is too great, because the residue will interfere with seedling establishment and intensive management of the new stand.

Excerpt from Practical Forestry in the Pacific Northwest: Protecting Existing Forests and Growing News Ones, From the Standpoint of the Public and That of the Lumberman, With an Outline of Technical Methods The object of this booklet is to present the elementary principles of forest conservation as they apply on the Pacific coast from Montana to California. There is a keen and growing interest in this subject. Citizens of the western states are beginning to realize that the forest is a community resource and that its wasteful destruction injures their welfare. Lumbermen are coming to regard timber land not as a mine to be worked out and abandoned, but as a possible source of perpetual industry. They find little available information, however, as to how these theories can be reduced to actual practice. The Western Forestry and Conservation Association believes it can render no more practical service than by being the first to outline for public use definite workable methods of forest management applicable to western conditions. A publication of this length can give little more than an outline, but attempt has been made either to answer the most obvious questions which suggest themselves to timber owners interested in forest preservation or to guide the latter in finding their own answers. Only the most reliable conservative information has been drawn, on, much of it Inning been collected by the Government. While the booklet is intended to be of use chiefly to forest owners, a chapter on the advantage to the community of a proper state forest policy is included, also a chapter on tree growing by farmers.

Researchers involved with the Pacific Northwest (PNW) Research Station Sustainable Wood Production Initiative have outlined some of the barriers and opportunities for sustainable wood production in the region. Sustainable wood production is defined as the capacity of forests to produce wood, products, and services on a long-term basis and in the context of human activity and use. The collective findings of these papers suggest that in the future, the regions wood supply will primarily come from private land, and the barriers and opportunities related to sustainable wood production will have more to do with future markets, harvest potential, land use changes, and sustainable forestry options than with traditional sustained yield outputs. Private lands in the PNW should be able to sustain recent historical harvest levels over the next 50 years, but regional changes in sawmilling capacity and uncertain market conditions may affect wood production in the region. Public perceptions of forestry, land use changes, and alternative forestry options are also discussed. These papers present preliminary findings and proposals for future work designed to help us understand the key issues related to sustainable wood production.
