Cotta was a pioneer of modern forestry, and was a catalyst concerning the transition from "timber production" to forestry as a scientific discipline. He was interested in all aspects of forestry, including studies involving long-term seeding, establishment of forested areas, and tree-cutting based on mathematic practices. Cotta's methodology was based on a geometric
