Diameter-Limit Cutting and Silviculture: A Comparison of Long-Term Yields and Values for Uneven-Aged Sugar Maple Stands

Computer simulations compared long-term sawtimber yields and values for uneven-aged sugar maple (Acer saccharum Marsh.) stands operated repeatedly by diameter-limit or selection system cutting. Findings show that the annualized sawtimber volume production and annualized revenues from selection system cutting exceed those from diameter-limit cutting. Also, present net worth values for selection system cutting exceed that of diameter-limit cutting at a 4, 6, and 8% interest rate. Findings also indicate that diameter-limit cutting in uneven-aged stands will result in less regular and less frequent yields of volume and value. The only advantage of diameter-limit cutting is the short-term financial gain that comes with removing a high volume during the first entry to a well-stocked uneven-aged stand. For sustained management, selection system cutting will prove superior for both sawtimber volume produced and recovered and its value.North. J. Appl. For. 22(2):111–116.
