Sugar maple provenance study: West Virginia outplanting - 10-year results

After 10 years, survival of sugar maple (Acer saccharum Marsh.) provenances outplanted in West Virginia did not differ significantly. Total height, height growth and dbh measurements were significantly different among provenances. Fifty percent of the trees had major forks below 9.0 feet. Thirty-eight percent of the trees had no forks but 71 percent of these were in the intermediate or overtopped crown class. Forking was not related to provenance. Latitude, longitude, and elevation of provenances were not strongly correlated with provenance performance.
