| Credits/ECTS : |
|
|
| Holder(s) : | Jacques Rondeux |
|
| Language : | Langue française |
|
| Course contents : | Stand structure (mean values, parameters describing evenaged and unevenaged stands), Stand measuring (complete enumeration, volume estimation, Bitterlich method). Land measurements (distances, angles, areas ¿ GPS, SIG). Growth of trees and stands, site, stocking and stand density assessment. Models for predicting growth and yield (classification - density-free, variable-density, diameter class, individual tree models, stand models), construction and application. Forest inventory ¿ statistical principles, sampling units, measurements and calculations. Type of sampling designs ¿ random and systematic. Types of sampling inventory ¿ multi-phase, stratified, cluster, multi-stage, point sampling (principles, error calculations, advantages and constraints). Planning and simulating a forest inventory (at management and national levels). Principles of estimation of variables dealing not only with timber but also with other non-timber resources such as: biodiversity, carbon storage, recreational potential. |
|
| Course objective : | Application of tree and stand measurement methods for assessing wood resources and improving forest management decision-making. Use of sampling methods and construction of models to assess growing stock and its growth, biodiversity, carbon and some non-wood values as recreation.
After completing the course the student is expected to
- be able to apply adequate measurement principles to obtain quantifiable information for forest management decision making;
- apply growth and yield concepts to case studies in temperate and tropical areas;
- be able to design various methods of forest inventories in order to estimate qualitative and quantitative variables and to have a critical examination of materials and methods used in exemplary case studies;
- achieve an in depth understanding of mensuration methods to be used to case studies such as: energy wood assessment, growth evolution, silvicultural scenarios;
- analyze the dynamics of forest stands to be able to implement decision tools in forest management and economics. |
