Download or read book Survival and Growth of White Ash Families and Provenances 15 Years After Establishment in West Virginia written by Thomas M. Schuler and published by . This book was released on 1994 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The survival, growth, and stem form of 45 white ash (Fraxinus americana L.) families nested within 22 provenances were evaluated 1 5 years after establishment in North Central West Virginia. Geographic family origins encompassed a wide area in the eastern and central United States, including locations from Maine in the North to Mississippi in the South to Nebraska in the West. Significant differences were identified among provenances for survival, stem form, total height, and stem diameter and among families within provenances for stem form and total height. Latitude was a significant indicator of provenance performance with performance declining north and south of the plantation latitude. Performance gains may be realized by using proper provenances then identifying superior families within these provenances for white ash artificial regeneration activities.

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.

Download or read book Survival Growth and Target Canker Infection of Black Walnut Families 15 Years After Establishment in West Virginia written by Thomas M. Schuler and published by . This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2The survival, growth, and rate of target canker infection of 34 black walnut (Juglans nigra L.) families were evaluated 15 years after establishment in north-central West Virginia. The progenies originated at locations in Pennsylvania, West Virginia, Tennessee, and North Carolina. There were significant differences between families in survival, incidence of target canker infection, total height, and diameter at breast height. The North Carolina and Tennessee sources were less suitable for the growing conditions of the test site; local and slightly more northern sources seem more suitable. Near the northern extremity of the range of black walnut, maintaining a viable native population of this species and using local seed sources in artificial regeneration activities are recommended.

This book was released on 2011 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assisted migration of tree species populations, or seed sources, is one of few adaptive strategies available to mitigate the projected effects of climate change on the structure, productivity, and distribution of forest ecosystems. In this report, the authors present the goals and objectives of a study intiated in 2008 to assess the potential of assisted migration as an adaptation strategy to manage for climate change in Ontario. In support of this study, they conducted a literature search on assisted migration and genetic variation in climatic response of forest tree species, through which were identified several hundred related scientific and technical publications. Citations and keywords for publications of greatest significance to using assisted migration as a climate change adaptation strategy are presented in the accompanying bibliography.--Document.
