National Academy of Sciences National Academy of Engineering Institute of Medicine National Research Council I.... A: ...... ......... A ~ (I C,,, ~...,).- The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineenng was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recogruzes the superior achievements of engineers. Dr. William A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. William A. Wulf are chairman and vice chairman, respectively, of the National Research Council.

PREFACE in response to a congressional request, the Board on Biology convened the Committee on Environmental issues In Pacific Northwest Forest Management ~1993 to review information concerning the status of resources of the Pacific Northwest and the relationship of those to supply and demand for forest products in other regions of the country. Committee members were selected for their expertise in forestry practices, public lands issues, biology, vertebrate and invertebrate ecology, rural sociology, and multiple-use land management. The committee grappled with many contentious questions. What activities ought to be included under the rubric of "forest management?" What was the presettlement character of Pacific Northwest forest landscapes and how have those forests and landscapes been altered by human activities? What are the ecological and economic consequences of changes in forest management practices? How are changes in forest management policy and practice in the Pacific Northwest influencing forest management outside that region? The definition and assessment of old-growth forests and their associated biodiversity and the implications of changing modes of management for their future were a particularly important part of the committee's deliberations. Nine meetings with guest presentations were held, including meetings in Portland, Oregon; Seattle, Washington; end Post Falls, Idaho. The public was invited to briefings in Washington, D.C., and Portland, Oregon. The original request for this study came from Congress In 1992, and lX
much has changed in between then and now. There is now little debate over the value and importance of conserving important areas of old growth forest. Conflict over forest-resource management continues, of course, but it is no longer polarized along such simple axes as "owls versus jobs." However, the basic question of how we are to achieve sustainable management of Pacific Northwest forests, as well as the forests of other regions in the context of increasing demand for the goods and services forests provide remains. How such specific initiatives as the Northwest Forest Plan fit into that objective is also unclear. It was clear throughout our study Mat few institutions exist to resolve the increasingly complex conflicts between the needs and aspirations of local communities and regional visions for the health of forest ecosystems. Improvement in communication, institutional learning, and institutional performance is badly neecled among government agencies, environmental groups, the business sector and the academic world. The problems presented in our charge are highly interdisciplinary, ranging from such fundamental natural science problems as the presettlement dynamics of forests and the implications of forest fragmentation for the management of species populations to very human impacts of changes in forest management on regional economies and rural communities. Furthermore, the committee was constantly aware of the reality that forest management in all regions is being undertaken with an increasingly diverse array of objectives across an increasingly complex array of ownerships. When the committee began its work, FEMAT (1993) had just been published and the President's Northwest Forest Plan just released. Over these several years, a number of the ~nanagement challenges and our understanding of a number of particular issues have changed. We have worked hard to incorporate those changes into this document. T am grateful to the committee for their willingness, indeed eagerness, to work across traditional disciplinary lines and perseverance in a process that became more drawn out than any of us expected. The committee would like to acknowledge the generous assistance of numerous persons who made presentations or in other ways enlightened the committee regarding the complex issues facing the Pacific Northwest, including Senator Mark Hatfield, U.S. Senate; Mark Walker, staff to Senator Hatfield; lack Ward Thomas, U.S. Forest Service; x

A grant frown the Ford Foundation provided important support to complete this project. This report has been reviewed in draft form by individuals chosen for their diverse perspectives and technical expertise in accordance with procedures for reviewing NRC reports approved by the NRC's Report Review Committee. The purpose of this independent review is to provide candle! and critical comments that assist the NRC in making the published report as sound as possible and to ensure that the report meets institutional standards for objectivity, evidence, and responsiveness to the study charge. The content of the final report is the responsibility of the NRC and the study committee and not the responsibility of the reviewers. The review comments and draft manuscript remain confidential to protect the integrity of the deliberative process. We wish to thank the following individuals, who are neither officials nor employees of the NRC, for their participation in the review of this report: Ellis Cowling, North Carolina State University; Paul Ellefson, University of Minnesota; ferry Franklin, University of Washington; and John Lapin, Oregon State University. The individuals listed above have provided many constructive comments and suggestions. Nevertheless, the responsibility for the final content of this report rests entirely with the authoring committee and the NRC. Several NRC staff members contributed in important ways to the committee's deliberations and to the assembly of this final report. Patricia Peacock and Eric Fischer each played important roles in our Xl
early discussions and the assembly of many early report draft reports. We also thank Gordon Orians for his thoughtful review of and comments on the draft report that was sent to review. We are especially grateful to Lee Paulson whose writing, editorial, diplomatic, and motivational skills contributed mightily to this find product. Norman Christensen, Chair . . xll
