Paperback. Condizione: New. Print on Demand. This book explores the viability and profitability of pruning Douglas fir trees to enhance the quality of lumber and veneer. The author examines the results of a study conducted on trees pruned at age 38 and harvested 20 years later. The study reveals that pruned trees produced peelable clear wood in 17 years, with only 10% meeting the highest commercial specifications for Douglas fir veneer. This highlights the importance of pruning at earlier stand ages to maximize the yield of high-quality wood. The book also discusses the factors limiting the recovery of high-quality veneer, such as tree taper and bole irregularities. These findings provide valuable insights for foresters and landowners seeking to improve the economic value of their Douglas fir stands through pruning.
