White Pine Management: Volume and Value Growth
Physical and financial yields from investments in white pine spacing control were estimated using a simulation model sensitive to site quality and changes in spacing. Financial returns were estimated using two assumptions each for price-diameter relationships, real interest rates, and precommercial spacing costs. Management guidelines were developed on the basis of the results. Precommercial thinning was not recommended. First thinnings were suggested as average tree size reaches commercial minimums (45 to 60 yr, depending on site and utilization standards) and final harvest was recommended at 60 to 75 yr, again depending on site and standards. Comparison of pine and oak management opportunities in southern New England favored pine, even if substantial investments were required for hardwood control. North. J. Appl. For. 4:197-201, December 1987
