This bibliography encompasses literature on the historic and current scope of nontimber forest product industries in the Pacific Northwest and includes references on international markets and trade that bear on these industries. Key themes in the bibliography are biological and socioeconomic aspects of resource management for sustainable production; procedures for identifying, monitoring, and inventorying important resources; means for technical innovation and resource development; and public education about nontimber forest resources. Social policy issues address the role of nontimber...

Ecosystem management is currently being proposed as a new resource management philosophy. This approach to resource management will require changes in how society approaches nature, science, and politics. Further, if efforts to implement ecosystem management are to succeed, institutional issues must be examined. This report identifies five problem areas where social science research can improve our understanding of how ecosystem management can best be implemented These include (1) the extent to which existing laws, policies, and programs may constrain or aid the implementation of ecosystem...

The Douglas-fir region of western Washington and Oregon and coastal British Columbia contains the most productive forestlands in North America. Yet disagreement among user groups and conflicting goals, policies, and laws have nearly paralyzed timber management on federal lands and greatly increased costs and complexity of management on nonfederal lands. Constructive compromise among competing interests is needed. Most private and state lands and some portion of federal lands will have timber production as a major objective for the foreseeable future. To accommodate this objective, we need...

This report is a summary of timber resource statistics for the North Coast Resource Area of California, which includes Del Norte, Humboldt, Mendocino, and Sonoma Counties. Data were collected by the Pacific Northwest Research Station as part of a State-wide multi-resource inventory. The inventory sampled private and public lands except reserved areas and National Forests. The National Forest System provided data from regional inventories of North Coast National Forests. Area information for parks and other reserves was obtained directly from the organizations managing these areas. Statistic...

This report is a summary of timber resource statistics for the Central Coast Resource Area of California, which includes Alameda, Contra Costa, Marin, Monterey, San Benito, San Francisco, San Luis Obispo, San Mateo, Santa Barbara, Santa Clara, Santa Cruz, Solano, and Ventura Counties. Data were collected as part of a statewide multi-resource inventory. The inventory sampled private and public lands except reserved areas and National Forests. The National Forest System provided data from regional inventories of the Los Padres National Forest. Area information for parks and other reserves...

This document highlights key items of information obtained from the published literature and from specific assessments, workshops, resource analyses, and various risk assessment panels conducted as part of the Tongass land management planning process. None of this information dictates any particular decision; however, it is important to consider during decisionmaking or when the consequences of any particular decision are evaluated.

Ecosystem management is the dominant paradigm for managing the forests of the Pacific Northwest. It integrates biological, ecological, geophysical, and silvicultural information to develop adaptive management practices that conserve biological diversity and maintain ecosystem functioning while meeting human needs for the sustainable production of forest products. Fungi are important components of forest ecosystem management because they perform essential ecological functions, many species are associated with late-successional forests, and commercial harvest of wild edible mushrooms...

Several smoke-dispersion models, which currently are available for modeling smoke from biomass burns, were evaluated for ease of use, availability of input data, and output data format. The input and output components of all models are listed, and differences in model physics are discussed. Each model was installed and run on a personal computer with a simple-case example. The steps required to obtain meaningful output for each model are described. Because validation data for wildland biomass burns were unavailable at the time of this assessment, recommending the use of one model over...

The use of time domain reflectometry to measure moisture content in forest soils and woody debris was evaluated. Calibrations were developed on undisturbed soil cores from four forest stands and on point samples from decayed logs. An algorithm for interpreting irregularly shaped traces generated by the reflectometer was also developed. Two different calibration equations were needed to estimate volumetric moisture content at the four sites, but commonly implicated soil characteristics (organic matter content, bulk density, and soil texture) could not fully account for the differences...
