Summary
Douglas fir was introduced on a large scale in mainland France around 50years years ago. The proportion of large timber will increase in the coming years as the stands age. Part of this resource will not meet the supply requirements of the largest sawmills and will depreciate in value. A wood processing method well suited to the utilization of this resource is peeling. In France, Douglas fir is not a peeled species due to its recent maturity. Veneers can be used to make plywood panels, but also LVL. A study of the optimal peeling parameters was necessary in order to obtain high-quality veneers. Next, a model taking into account the silvicultural data of a stand was developed to estimate the mechanical properties of LVL beams. It made it possible to predict the mechanical properties of beams made from trees from three plots with "contrasting" silvicultural itineraries. A simulation of pruning these trees at 20 years of age shows the value of using this decision-making tool for forest stand management.
