Aims
By the end of this course, the student will be able to handle instruments, tools and strategies that are to be implemented for the quantification of tree and stand characteristics, both from static and dynamic (increments) points of view. This quantification is needed for increased understanding of ecosystem functioning, as well as for present and future forest ressources assessment.
Main themes
1. Definitions, significance, measurement or estimation of current tree (e.g. diameter, circumference, basal area, heights, volumes, forms, crown parameters) and stand (e.g. stem distributions, diameters, heights, volumes, stand densities, productivity) characteristics.
2. Tree and stand increments: concepts, estimation, tools and models
3. Forest inventory - complete tree tally and sampling: (i) fundamental concepts of sampling theory, (ii) sampling units, (iii) inventory planning and analysis, (iv) sampling designs (e.g. simple random, stratified random, systematic, single- and multi-stage, multiphase, repeated samplings).
Content and teaching methods
This course presents the measurement and sampling methods as well as the essential tools, used for the quantification of forest trees and stands (current characteristics and increments). The theoretical principles are illustrated and implemented during practical exercises carried out in the field or in classrooms.
