Course contents:

1. The rational planning model.

2. General information on measurement, estimation, errors and uncertainty.

3. Mensuration for single-trees. Diameter, height, bark, growth in diameter and height, age, stem form, taper tables, volume and growth predictions.

4. Mensuration for stands (and sample plots). Diameter distribution, mean diameter, relascope, mean height and dominant height. Variations within stands and stand volume estimation. Random, systematic and subjective sampling. Growth prediction. Site quality.

5. Mensuration for forests. Area determination. Stratified sampling. Sampling methods (total measurements, sample plot inventories, stand inventories. Large-area stand inventories. Permanent sample plots. Laser scanning.

6. Examples of problems related to mapping of e.g. non-stationary populations.

7. Photogrammetry.

Learning outcome:


The students should be familiar with methods and tools used for mensuration and calculation of various variables for single trees, sample plots, stands and forests. They should also be able to make evaluations of the accuracy and sources of error in measurements/calculation/results. Students should be able to put their knowledge of mensuration into a context so that it can be utilised when planning and making decisions for treatment of forests. Recognise the problems that might be associated with mapping of other goods from the forests than timber resources. The students should also know the main components of a modern forest inventory carried out by means of airborne laser scanning.


The student should be able to do calculations related til single trees, forest stands, and forests based on a collected data material.

General competence:

The student should have obtained knowledge about how estimates of timber volume etc. in are obtained in forest populations.
