Book Description
S2In West Virginia, yellow-poplar (Liriodendron tulipifera) is abundant and is a prime candidate for increased utilization in a variety of manufacturing industries. Computer simulations are a cost-effective tool for estimating potential cutting yields from lumber. They can be used to promote increased use of yellow-poplar in the furniture, cabinet, and architectural woodworking industries and may also lead to increased utilization of the lower grades of lumber. This paper describes the data collection methods and the format of the new West Virginia yellow-poplar lumber defect database that was developed for use with computer simulation programs. The database contains descriptions of 627 boards, totaling approximately 3,800 board feet, collected in West Virginia for grades FAS, FASIF, No. 1 Common, No. 2A Common, and No. 28 Common.S3.

Book Description
This text addresses six ecological themes: shifting public values, expectations and laws; social and cultural dimensions; humans as agents of ecological changes; biological and ecological dimensions; economic dimensions and information collection and evaluation. The set includes a graphically-illustrated summary volume, synthesizing the key scientific and management findings and conclusions of the six topics. The book is accompanied by a CD containing the full text of the three volumes in PDF format searchable by table of contents and keywords.

Book Description
Until recently, natural resource management of such commodities as timber and wildlife was driven largely by the desire to exploit these resources. During the past three decades, however, ecologists have warned that this approach to natural resource management could have unforeseen consequences because it ignored how ecosystems function within the landscape. Federal agencies that oversee forest and wildlife resources have begun to implement different schemes of ecosystem management, schemes that vary enormously among agencies. Contributors to this volume--leading experts who are agency personnel as well as researchers--now clarify the key elements of sound ecosystem management and offer prescriptions for implementing them. The authors discuss definitions of ecosystem management, sustainability of ecological systems, landscape ecology, resource management at different scales and in an ecosystem context, new advances in computer technology that facilitate classification schemes for ecosystems, ecosystem restoration, biological diversity, and public concerns. Throughout, the experts agree that management practices must be sustainable: that production of commodities, such amenities as recreation and aesthetics, and biodiversity must not be allowed to decline over time.
