Available in PDF, EPUB and Kindle. Book excerpt: After a brief description of silvicultural problems, the author tells how to prescribe herbicidal sprays for aerial, application in Pacific Northwest forests. The publication offers a detailed discussion of the five basic considerations: (1) selection of the best herbicide or herbicides, (2) amount of herbicide to be applied per acre, (3) carriers, (4) volume of spray per acre, and (5) seasons for application of aerial sprays. Appendixes provide standard treatments for many common silvicultural problems in site preparation and to release young conifers from shrub and weed tree competition. Also included is a glossary of agricultural chemical terms and a list of abbreviations used in brush control literature. This is a working manual for silviculturists based upon more than 20 years research and experience of Federal, State, and industrial foresters. It provides much information not generally available in the literature and tells how to use this knowledge in Pacific Northwest silviculture. Although designed primarily for the Pacific Northwest, the basic information should be useful in culture of coniferous forests far outside this region.

Book excerpt: In August 20-23, 2004, a conference was held in Kamilche, WA, with the title S2Productivity of Western Forests: A Forest Products Focus. S3 The meeting brought together researchers and practitioners interested in discussing the economic and biological factors influencing wood production and value. One of the underlying assumptions of the meeting organizers was that management activities would be practiced within a framework of sustaining or improving site productivity; thus, several papers deal with methods to protect or improve productivity or discuss new studies designed to test the effects of various practices. This proceedings includes 11 papers based on oral presentations at the conference, 3 papers based on posters and 2 papers describing the Fall River and Matlock Long-Term Site Productivity study areas visited on the field tours. The papers cover subjects on forest harvesting activities, stand establishment, silviculture, site productivity, remote sensing, and wood product technologies.

Available in PDF, EPUB and Kindle. Book excerpt: As a result of an increasing population, our reduced acreage of forest land will be called upon to produce maximum amounts of wood fiber, to satisfy an ever-increasing demand for recreational use, and to produce maximum amounts of clean, pure water. Under such demands, forestry must be practiced with an intensity that is beyond our ability to conceive at present. Of necessity, every tool, including chemicals, must be used in this intensive management for the good of mankind. To achieve these aims, it will be also necessary that we quickly acquire a detailed and intimate knowledge concerning the interactions that occur within forest ecosystemsnot only natural interactions among plants, but also those that occur when we artificially induce changes in structure or composition in communities or ecosystems by artificial means. Such changes may not only affect vegetation; they may also affect atmospheric, wildlife, and microbiological conditions as well. Chemicals are useful, necessary tools for helping to meet needs for food, wood fiber, and water, while man readjusts his numbers and modes of life to the rapidly dwindling resources of the earth. The more selective, less persistent chemicals will continue to play an important role in forest resource management, probably for several decades. However, chemical use must eventually be minimized, for it is simply a system of treating symptoms of unhealthy ecological conditions created by nature or man in the past. Technological, environmental, and socioeconomic factors will add new dimensions to chemical use, placing greater demands on the research and development process. Our pressing need, aside from solutions to problems of population pressures and extravagance in natural resource use, is rapid development of the ecological knowledge necessary to manage and maintain a healthy biosphere with minimum use of chemical tools.

Available in PDF, EPUB and Kindle. Book excerpt: Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.

Available in PDF, EPUB and Kindle. Book excerpt: Herbicides were tested on 16 common shrubs and weed trees during the past 24 years. The woody plants included snowbrush ceanothus, deerbrush ceanothus, mountain whitethorn, varnishleaf ceanothus, sprouting and nonsprouting forms of greenleaf manzanita, hairy manzanita, hoary manzanita, golden chinkapin, golden evergreenchinkapin, Saskatoon serviceberry, Pacific madrone, salmonberry, western thimbleberry, scrub tanoak, and canyon live oak. Chemicals tested included 2,4-D, dichlorprop, 2,4,5-T, silvex, 2,4-DB, amitrole, amitrole-T, 2,3,6-TBA, AMS, picloram, KreniteTM, triclopyr, and an experimental carbamate compound. Low volatile esters of 2,4-D and 2,4,5-T proved the most effective and versatile herbicides for silvicultural use in western Oregon. Results of the screening tests are related to comparable data from small plot tests and project-scale aerial spray trials. To aid silviculturists, useful treatments and the most effective herbicide are shown in bold-face type for each shrub and weed tree.

Available in PDF, EPUB and Kindle. Book excerpt: Pursuant to a congressional request, GAO reviewed per-acre cost information on the Forest Service's use of herbicides and alternative treatment methods for site preparation, release, and thinning activities for six forests in the Pacific Northwest. GAO noted that cost comparisons between each forest may be inaccurate and limit the usefulness of the data because costs vary due to the different physical characteristics of each forest. GAO found that: (1) the Siuslaw National Forest significantly reduced its herbicide program in fiscal year 1983, and used manual or mechanical methods on land on which it would normally have used herbicides; (2) the Forest Service accounting system did not separate out its administrative costs; and (3) manual or mechanical applications normally require more follow-up treatments and ultimately realize less timber growth and harvest levels than herbicide applications, but the cost data for those treatments were not available.
