Foreste, boschi, arboricoltura da legno

Abstract

In protected areas the forest ecosystem management is directed to define the best approaches with high protection levels from ecological, historical, anthropological and landscape point of view. The conservation purposes have to be taken in consideration to not disturb the natural and functional processes, and therefore any forest human activity has to be done. Through a detailed analysis of the relations among functionality, stability, productivity and genetic diversity, the statement of the reasons for application of close-to-nature silviculture is described and discussed. Some specific silvicultural systems are illustrated on the basis of very large quantity of data and information originated from researches carried out for long time. A major challenge facing modern silviculture is to reconcile the traditional objectives of timber production with the demand for multifunctional forest ecosystems which arises from the society. The preservation of the functionality is strictly related to the forest genetic pool which is the basis of biodiversity, as it represents the basis for adaptation and survival of species and individual.
