About this course

Knowledge about forest growth and yield is an essential prerequisite to understand the reaction of trees and forest stands to treatment in order to plan silviculture. This knowledge concerns both ecological process and statistical descriptions of the development of trees and forest stands. In this course we will discuss research-based knowledge about recent challenges for silviculture in Norway: use and conversion to continuous cover forestry, climate adaptation, and site-adapted silviculture. Within these topics we will address methods like site mapping, natural regeneration, pre-commercial thinning methods, thinning methods, conversion methods, selection system, mixed forest management, and management of broadleaved species.

Learning outcome


Students will learn about recent silvicultural methods and their effects on trees and the forest ecosystem. Students will learn some basics in forest growth and yield, which determine the effects of silvicultural on stand development.


Students will be able to choose between silvicultural options depending on management objectives, conditions for growth, and stand development. Students will be able to evaluate effects of the chosen silviculture on growth and stand development. Students will be able to understand and apply relevant research literature in the field, also in the future.


Students should be able to see the advantage of knowledge-based forest management as opposed to traditions and hierarchical orders.

General competence:

Students will be able to find, read, and communicate the content of relevant research literature within the field.

  • The core of the course is a literature study of research papers supported by seminars. The content of the research papers will be presented by students or teachers as a basis for the discussion during the seminar. Excursions will focus on research and the practice of silviculture. The semester assignment will train the process of finding relevant research results about a chosen topic and to present research results. Students summarize the most important content of the course literature and the seminars in a note book.
  • Seminars and coments on assignments. The course has web pages in Canvas, where all activities are announced. The lecturers are available for questions during office hours.
  • SKOG220
  • Combined assessment:

    • Portfolio consisting of written summaries of the first 4 course papers (3 best out of 4) counts 10%.
    • Portfolio consisting of note book (8 summaries of course papers, 7 discussions related to course papers, 3 summaries of student-specific papers) counts 65%.
    • Oral midterm exam on forest growth and yield counts 25%.

    All of the above elements must be passed to pass the course. For elements composed of more than one mark, the average mark must be passed.

  • The external examiner approves and takes part in the grading of the exams and the note book.
  • Excursions. Exercise on plagiarism signed. Oral presentations of course papers during seminars.
  • If there are few registered students, an alternative teaching plan may be given in the course.
  • Seminars, 4 days excursion.
  • 10 credits for SKS303.
