Abstract

The discipline of Forest operations is constantly challenged to find solutions for unique problems. Each forest site requires specific technological approaches and machinery based on given management goals and ecological and environmental circumstances. Various terrain types and soil conditions, harvesting costs and taking care of the workforce by creating safe working conditions are some of the a

Objective

In this course, students will learn to use a wide variety of approaches grounded in the natural sciences, engineering and technology to develop solutions tailored to unique challenges from the field of forest operations. The course is aimed at students who either plan an academic or professional career in the field of forest operations, or who will work at the interface between forest operations and the various related disciplines, such as forest ecosystem management and forestry in the wider sense. After participating in this course students will have acquired foundational knowledge of a wide variety of core elements in the field of forest operations: • The course will provide students with the ability to describe and differentiate site and stand conditions from an engineering perspective. • Students will gain an overview and good working knowledge of current technology used in forest operations in Switzerland and around the world. • Students will acquire the ability to assess the strength and weaknesses of the most commonly used equipment and analyze their suitability for a given set of environmental, economic and social factors. • Students will be able to combine different types of technology to create an optimal harvesting system for a given task, and assess a given system for its task specific suitability. • Participants will be able to assess the sustainability and potential short- and long-term impacts of harvesting systems under ecological, economic and social constraints.
