Biometrics

Não aplicável

Theoretical-practical classes, with execution of a set of practical works (in the forest area of the ESAC campus for data collection, use of the instruments and procedures for data collection, and in the classroom for information processing).
Tutorial guidance for monitoring learning and use of instruments.

The objectives of the curricular unit are reflected in the acquisition of two core skills:
1 – Knows the principles and techniques for measuring and/or quantifying the variables associated with forest resources;
2 – Knowledge of the procedures for stock and yield evaluation.

The syllabus for the acquisition of two skills described are divided into two learning modules:
Module 1 – Variables to be collected, measurements to be performed, data collection and information processing:

a) knowledge of dendrometric variables (diameter, basal area, height, stem shape, volume)
measurement processes and the equipment necessary for their determination;
b) knowledge of the main errors of measurement and observation;
c) use of equations and tables in biometrics.

Module 2 – Methods of sampling, sample plots installation and data collection:

a) knowledge of the role of sampling in the collection of biometric information;
b) use of sampling procedures and installation of inventory plots;
c) processing of data collected in the field.

• - Module 2 fieldwork and report - 50.0%
• - Evaluation Module 1- Test - 50.0%
