Book Description
Survival, total height, diameter at breast height (d.b.h.), and stem quality of sugar maple trees of different provenances were compared 25 years after establishment in north-central West Virginia. Provenances were from Michigan, Minnesota, West Virginia, Massachusetts, New Hampshire, Vermont, Maine, and Quebec, Canada. There were significant differences between provenances for all traits except stem quality. By provenance; total tree height ranged from about 49 to 37 feet; d.b.h. from 6.7 to 3.6 inches; and survival from 100 to 15 percent. The predictability of total tree height 25 years after establishment based on mean provenance height at age 2, 6, 10, and 15 years is discussed. Results suggest that juvenile height growth may be a good predictor of mature height performance, thus decreasing the need for rotation-length trials.

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.
