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.

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.
