Download or read book Forest Residues in Hemlock spruce Forests of the Pacific Northwest and Alaska written by Robert H. Ruth and published by . This book was released on 1975 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Choosing Forest Residues Management Alternatives written by John M. Pierovich and published by . This book was released on 1973 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest residues management involves disposal, modification, or utilization of wood products. The costs and benefits of the several alternatives available to forest managers must be evaluated in relation to land management goals and constraints in four areas: (1) unused wood fiber, (2) conflagrations, (3) impairment of forest resources, and (4) opposition to treatment of residues. Advance modification of fuels or installation of fuelbreaks on strategic locations may be the best residue management for fire control, but probable loss must be weighed against cost. A simple framework is proposed that uses quantitative data on costs, benefits, and probabilities, but the opportunity exists to use qualitative data until research results become available.

This book was released on 2011-07-21 with total page 2087 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European Symposium on Computer Aided Process Engineering (ESCAPE) series presents the latest innovations and achievements of leading professionals from the industrial and academic communities. The ESCAPE series serves as a forum for engineers, scientists, researchers, managers and students to present and discuss progress being made in the area of computer aided process engineering (CAPE). European industries large and small are bringing innovations into our lives, whether in the form of new technologies to address environmental problems, new products to make our homes more comfortable and energy efficient or new therapies to improve the health and well being of European citizens. Moreover, the European Industry needs to undertake research and technological initiatives in response to humanity's "Grand Challenges," described in the declaration of Lund, namely, Global Warming, Tightening Supplies of Energy, Water and Food, Ageing Societies, Public Health, Pandemics and Security. Thus, the Technical Theme of ESCAPE 21 will be "Process Systems Approaches for Addressing Grand Challenges in Energy, Environment, Health, Bioprocessing & Nanotechnologies."
Download or read book Waste to Wisdom written by and published by . This book was released on 2018 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest residues, including unmerchantable and small-diameter trees, tops, and limbs, produced during thinning and timber harvest operations can be used to produce renewable bioenergy and bioproducts. The more efficient utilization of forest residues could also help offset the high costs of forest restoration activities, fire hazard treatments, post-harvest activities and forest management in general. Forest residues have long been underutilized and treated as waste materials because of their high collection and transportation costs as well as their low market value. While open burning is often employed to dispose of forest residues, this practice generally results in substantial negative economic and environmental impacts, including increased forest management costs and reduced local air quality.
Download or read book Utilization of Residual Forest Biomass written by Pentti Hakkila and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increase in the demand for wood results in improved recovery and less residual biomass in the forests. Paradoxically, interest in forest residue as a renewable source of raw material seems to be in a reverse ratio to its availability in a certain area. Finland and Sweden are probably more dependent on forestry and forest in dustries than any other developed countries in the world. A sufficiency of raw ma terial for integrated forest industries is vital for the national economy of both countries, and a great deal of attention is being paid to the long-term potential of unutilized biomass left behind in logging operations. Furthermore, since these countries possess no reserves of fossil fuels, and since their per-capita consump tion of primary energy is exceptionally high, they also consider unmerchantable forest biomass a realistic source of indigenous energy. A joint Nordic research project on harvesting and utilization of logging residue was carried out in 1969-1976 under the auspices of the Nordic Research Council on Forest Operations. This fruitful cooperation soon gave rise to related national projects in Sweden, Finland, Norway, and Denmark, stimulating further research and producing practical applications. Concurrently, particularly after the worldwide energy crisis in 1973, research on all aspects of utilization of forest bio mass mushroomed in the United States, Canada, and the Soviet Union. An ex plosive increase occurred in both the number and diversity of biomass studies.
Download or read book Renewable Energy from Forest Resources in the United States written by Barry Solomon and published by Routledge. This book was released on 2008-10-30 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in biomass energy resources from forests, farms and other sources has been rapidly increasing in recent years because of growing concern with reducing carbon dioxide emissions and developing alternatives to increasingly scarce, expensive and insecure oil supplies. The uniqueness of this book is its coverage of biomass energy markets in the US from an economic as well as technical perspective. Existing books typically focus on single markets or technical aspects at the exclusion of economics, and have given greater coverage to biomass energy outside the US. This edited collection has three main parts. Part One provides a historical overview of forest biomass energy use in the US; the major technologies, economics, market prospects, and policies. Part Two presents forest biomass energy assessments, including life cycle and sustainability perspectives, and Part Three includes five sets of regional case studies. After reviewing the history of wood energy use in the US and technology options, the book shows that forests could displace sixteen per cent of domestic transportation fuel use in 2030. Renewable Energy from Forest Resources in the United States includes a Foreword from Chris Flavin, President of the Worldwatch Institute.
