In a first step these teachings were characterized by a strong naturalistic orientation attributable to the scientific
thought of the first academics. It was naturalism based on the application of science to the management of forest
systems and is identified by the presence of materials of this profile as well as the practical character of the studies.
In a second stage, due to the economic requirements of the country and to the academic influence over other
technical engineering education, the teachings, maintaining the naturalistic conception, acquired a productivist
character to include more technological content.
