Plain Language Summary

One of the objectives of silviculture is to increase forest productivity to meet the needs of various markets. Depending on their intensity and distribution over time, different silvicultural activities (e.g. pre-commercial thinning, commercial thinning) can affect wood properties. This book chapter summarizes the effects of silvicultural practices on wood quality. It describes how factors such as stand density in natural forests, initial spacing in plantations, thinning and harvesting age affect the mix of products derived from timber harvesting. Initial spacing in plantations, for example, has a significant effect on the development and number of branches on the trees. In fact, the more branches there are, the more knots there will be in the processed products. The presence of knots diminishes the mechanical properties of the products manufactured.

This chapter briefly describes desirable tree and wood characteristics per product category (structural wood, veneer, pulp and paper, etc.). It also shows that silviculture aimed at maximizing tree growth has negative impacts on the mechanical properties of wood.
