NEW SILVICULTURAL ALTERNATIVES IN YOUNG OAK HIGH FORESTS. CONSEQUENCES ON HIGH QUALITY TIMBER PRODUCTION

Objective

The main objective of this project is to specify the optimal silvicultural practices in Quercus petraea and Quercus robur high forests of less than 15m of height, reducing the costs, concentrating the inputs and speeding up the height growth of better selected individuals (phenotypes) i.e. trees which will exhibit a high response of radial growth to subsequent thinnings, a lower tendency to develop epicormic shoots, a better self pruning and also wood properties in accordance to the requirements of the joinery and furniture industries and avoiding frost shakes on standing trees.

This main objective can be divided into :

- the set up of criteria to early select the crop trees and;
- the specification of the silvicultural practices to be performed on behalf of
these selected trees.

The rotation of Quercus is long and therefore modelling and simulation tools will be useful to test the effect on harvested timbers of a dynamic silviculture performed in up-to-15-m-height stands. The creation of these tools constitutes the second objective of the project.

This second objective can be divided into 3 sub-objectives :

- building of a pertinent growth model;
- building of end-user oriented wood properties models;
- building of a decision support tool available to the silviculturists.

With the results gained in the project we aim to provide :

- advices to foresters concerning the silvicultural practices at young stage;
- specifications of wood provided to industries and coming from stands where
an intensive silviculture has been applied in the young stages, in terms of basic
wood properties, frost cracks tendency and after drying behaviour;
- a decision support tool taking into account the requirements of the joinery and
furniture industries.
