Professor PASQUALE ANTONIO MARZILIANO
Objectives The objective of the Tree meansurement and Forest Management is to provide students with basic knowledge, theoretical and practical, on the criteria and techniques for the reliefs in forest, processing dendrometric data, the estimate of the wood mass. the course intends to introduce the basic criteria of the main methods of forest planning aims at applying interventions to improve the forest stands and in particular provides notions on the criteria and techniques for the preparation of plans for their management.
