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 I00 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.
