Preventive Silviculture

Base Knowledge

Although general silviculture notions are given, it is convenient for students to have in mind the basic concepts associated with the characterization of forest stands and silvicultural operations.

Teaching Methodologies

Classes in the classroom, in the field and in support of ongoing activities, through the execution of operations learned in the classroom

Learning Results
