Abstract
Abstract Pruning of coast Douglas-fir for (Pseudotsuga menziesii var. menziesii) lumber was evaluated by using new product-recovery information and new computer software. The results showed that higher financial returns from pruning are achieved by pruning early in stands that have a higher site index and that will be fertilized. Interest rates and the premium for clear lumber will have major impacts on the dollar return from pruning. West. J. Appl. For. 3(2):46-48, April 1988.
