Book excerpt: Proceedings of a workshop co-sponsored by the USDA Forest Service, the State University of New York, and the Society of American Foresters. Presented were papers on the methodology of sample tree selection, tree biomass measurement, construction of biomass tables and estimation of their error, and combining the error of biomass tables with that of the sample plots or points. Also presented were papers on various aspects of biomass research currently being conducted in the United States, Canada, and abroad.

Available in PDF, EPUB and Kindle. Book excerpt: Existing literature on procedures for estimating tree biomass for northeastern tree species includes a number of research studies that are specific and localized. As a result, there is little consistency in these estimation procedures, which are largely in the form of regression equations. In addition, many species are ignored that need to be quantified when inventories of forest resources are conducted over extensive areas. This makes it difficult to determine the most appropriate biomass-estimation procedures. In this paper, an evaluation is made of prediction models and their application over the entire range of northeastern tree species. Recommendations are also made on procedures for the more nontimber oriented elements of total forest biomass-shrub biomass, foliage biomass, stump and root biomass, and biomass on unproductive forest land.

Available in PDF, EPUB and Kindle. Book excerpt: This international symposium on theory and techniques for assessing the accuracy of spatial data and spatial analyses included more than ninety presentations by representatives from government, academic, and private institutions in over twenty countries throughout the world. To encourage interactions across disciplines, presentations in the general subject areas of spatial statistics, geographic information systems, remote sensing, and multidisciplinary approaches were intermixed throughout the three days of sessions.

Download or read book West Virginia Yellow poplar Lumber Defect Database written by Lawrence E. Osborn and published by . This book was released on 1992 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
