Learning Objectives
Knowledge: wood and its properties, for the forest management for wodd production or in the forest operations and in the woodworking.
Skills acquired: assessment of the quality of timber and suitabilty of its uses, analize the behaviour of wodd (as round or sawn wodd, or as a artefact), and assess the correctness of the environment conservation condition.

Knolewdge acquired:
enhance knowledge of wood, of wood based products, about utilisation and conservation, on wood processing and environmental aspects.
Additional expertise on wood technology acquired: from load-bearing timber to wood as biofuel.
Skills acquired (at the end of the course):
- professional skill: 1) expertise on the choice of wood species and the correct use 2) competence on wood processing and wood conservation;
- research ability: 1) potentiality of innovation about wood and wood products, 2) critical aspects about wood in relation to provenance, silviculture, forestry.
