Three Basal Area Level Harvest Trials in Uneven-Aged Northern Hardwoods
Beginning in 1958, northern hardwood stands with initial basal areas ranging from 93 to 106 ft²/ac were harvested to residual basal areas of 70, 55, and 40 ft²/ac. Subsequent harvests of the stands over a 32-yr period illustrated potential treatments available to absentee owners of similar stands in small woodlots. In all cases stand quality improved and stand structure became more balanced, with a decrease in the number of trees greater than 20 in. dbh. At discount rates of 2% to 4%, economic returns were greatest for the 70 ft² treatment with a 10 yr cutting cycle. At discount rates of 6, 8, and 10%, the 55 and 40 ft² treatments with 18-and 22-yr cutting cycles, respectively, outperformed the 70 ft² treatment due to greater volume removed during the first (1958) harvest.
