    Constructive Use of Herbicides In Forest Resource Management
    (1975-06) Michael Newton
    Herbicide-based methods have come into use as partial or full .substitutes for tools lonfg used in limber stand establishment and management. Some are effective and economical, offering a way to improve resource productivity. Yet their environmental impacts are being questioned in much greater detail than were the practices they replace. This article describes some of the practices and examines some of the questions regarding the relative impacts of some analogous chemical and non-chemical methods. The choice of methods is considered as an active process that takes into account both the advantages and disadvantages of each option in management and social contexts.

    Forest management for minimum conflict
    (1974-12) Michael Newton
    Conflicts in forest management result from fear among user groups that specific management practices will jeopardize their interests while ostensibly favoring others. This paper emphasizes improvement in understanding of various practices so that groups will not become alarmed unnecessarily over inconsequential matters and will participate in compromise management options that deliver optimum ratios of benefits to all parties. Examples are outlined to illustrate that spotted owls and timber production may be compatible on a given acre, that productive alternatives can be found to using repellents or shooting large numbers of game animals to safeguard forest regeneration, and that intelligent use of DDT or 2,4,5-T may well be ecologically the safest way to live with some forest pest problem. Public acceptance of forest practices needed for maintenance of resources exposed to constant pressure requires an educated public. I propose that information on conservation and resource management-and not tied to user interests-be promoted at all educational levels, beginning with elementary schools and extending to graduate schools and legislative bodies.

    Nutrient Loss From Disturbed Forest Watersheds In Oregon's Coast Range
    (1983) James H. Miller; Michael Newton
    Dissolved nutrients were monitored bi-weekly in stream water draining 14 upland watersheds in Oregon's Coast Range after spraying with 2,4,5-T + 2,4-D, clearcut harvesting and slash burning. Anion generation and leaching were primarily studied. The nitrate concentrations fell and the bicarbonate concentrations rose during summer low-flows from treated watersheds without detectable increases in loss of macronutrients (N, Ca, Mg, K, Na). The stream water concentrations of bicarbonate (the most prevalent anion) related to watershed orientation and the degree of devegetation. Nitrate concentrations appeared to be correlated positively with watershed drainage rates. Studies with incubated soils and field sampling of soil solution indicate that denitrification probably minimizes nitrate loss from saturated soils during frequent winter to spring storm periods.

    Principles of Silviculture: Current Trends and their Significance
    (1972) Robert E. Buckman; Michael Newton
    A public debate is underway in the United Stater about forest management practices in general and silvicultural practices in particular. The debate stems from environmental concerns for forest land, especially esthetics and watershed protection. It also stems from sharply differing views on the uses to be made of forest land, highlighted by wilderness and recreation use on one hand and timber production on the other. Added to the controversies are rapidly increasing uses of forest lands for a variety of purposes. Clearcutting practices on National Forests in three States -West Virginia, Wyoming, and Montana- have been the focal point for the debate. There is question whether clearcuting is needed, and if it is needed, cannot the workmanship be improved? Regeneration failures have attracted concern. There is much criticism of watershed management practices and road building techniques. And the charge is made that the Forest Service (the Federal agency administering the National Forests) favors some uses of the Forests and slights others. The Forest Service has appointed study teams to 1 Director. Pacific Northwest Forest and Range Experiment Station, USDA, Forest Service, Portland, Oregon. Associate Professor of Forest Ecology, Oregon State University, Corvallis, Oregon.
