Book Crop tree Release Thinning in 65 year old Commercial Cherry maple Stands 5 year Results

Download or read book Crop tree Release Thinning in 65 year old Commercial Cherry maple Stands 5 year Results written by H. Clay Smith and published by . This book was released on 1994 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop trees were selected and released in a 65-year-old cherry-maple stand in north central West Virginia. Six crop-tree treatments were evaluated. Crop trees were selected based on potential for quality sawtimber and veneer products. Initially, released crop trees averaged 12.5 inches d.b.h. and 80 feet tall and were released an average of 13 feet from the edge of their crown. Five-year stand growth, mortality, and in growth are discussed for the treatments. Tree quality as related to butt-log grade and epicormic branching also are discussed. Detailed information is given for d.b.h. growth as related to degree of crown release. In general, black cherry, free-to-grow crop trees for the 40 and 60 crop-trees-per acre treatments grew 1.0 inch in 5 years. Similar crop trees in the control areas, where tree crowns were not released, grew 0.6 inch during the same period. Growth response increased with an increase in number of sides of the tree crowns released. After 5 years, less than 2 percent of the released crop trees had a reduction in butt-log quality due to epicormic branching.

Book West Virginia Yellow poplar Lumber Defect Database

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.

Book Thinning Cherry maple Stands in West Virginia

Download or read book Thinning Cherry maple Stands in West Virginia written by Neil I. Lamson and published by . This book was released on 1988 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2In northern West Virginia, 60-year-old cherry-maple stands were thinned to 75, 60, and 45 percent relative stand density. Analysis of 5-year growth data showed that basal-area growth was not reduced by thinning. Cubic-foot and board-foot volume growth decreased slightly. Individual-tree growth of all trees, dominant/codominant trees, and the 50 largest diameter trees per acre was significantly increased by thinning. Dominant/codominant trees in the 45 percent plots grew about 0.42 inch more in 5 years than those in the control plots. Optimum stand density probably is less than 60 percent relative stand density.S3.

Book Thinning Increases Growth of 60 year Old Cherry maple Stands in West Virginia

Download or read book Thinning Increases Growth of 60 year Old Cherry maple Stands in West Virginia written by Neil I. Lamson and published by . This book was released on 1985 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2In north-centrai West Virginia, previously unmanaged, 60-year-old cherry-maple stands were thinned to 60 percent relative stand density. Thinning reduced mortality, redistributed growth onto fewer, larger stems, and increased individual tree growth. Five-year periodic basal area growth per acre was 1.2 times greater in thinned stands than in unthinned stands. Periodic basal-area growth of individual trees was greater in thinned stands than in controls: 3.0 times for all stems and 1.3 times for dominants and codominants. Relative stand density in the thinned stands increased 1.6 percent annually.S3.
