Learning objectives
The course aims to provide knowledge about the physical environment where organisms live; the relationships between individuals, populations, communities and their environment; the basic elements useful to study ecosystems.
Moreover, the course aims to provide knowledge about the classification and structure of forest stands; the analysis of forest ecosystem services; the comprehension of appropriate forest management strategies and schedules.
Knowledge of the functioning of forest ecosystems, their ecosystem services, the effects of climate change, and the tools to maximize the former and mitigate the latter, is essential for AT graduates to plan and implement an effective and sustainable use of natural resources, in particular forests.
Expected learning outcomes
At the end of the course the student shall acquire:
- Basic knowledge on the structure and functions of ecosystems, in order to achieve the skills for sustainable management of the environment.
- Capacity to describe the structure and composition of forest stands using quantitative indicators.
- Capacity to recognize the main forest cover types in Lombardy and to estimate their natural development.
- Capacity to assign prevalent ecosystem services to forest stands and to decide on the best management strategy to attain them
- Capacity to recognize the boundaries of social, economic and environmental sustainability, complying to the limitations imposed by forest regulations, estimating the efficacy of forest management strategies towards the mitigation and adaptation to climate change in forests.

Lesson period
First semester
Prerequisites for admission
Basic knowledge of biology, chemistry, mathematics and physics.
Working knowledge of English (B2)
Assessement methods and criteria
Module 1:
Written test (2 hours) with two short essay questions and one quantitative ecology exercise.

Module 2:
Oral exam (0-18 / 30) + herbarium with 20 forest species (0-6 / 30) + written descriptive report of a forest population (0-6 / 30). Herbarium and report must be prepared according to the instructions communicated at the beginning of the course and published on Ariel in the teaching material.
Evaluation criteria:
a) herbarium: correct classification and knowledge of the ecology and forestry of the species
b) report: correct use of silvicultural terminology, correctness of dendrometric calculations, correctness and quality of maps, quantitative graphs and bibliography, consistency between site and dendrometric characteristics of the forest, its main function and the management recommendation, level of detail of the management recommendation and its compliance with forest regulations.
c) oral questions: knowledge of the main ecological factors, ecosystem services, and management systems of the main forest types of Lombardy; knowledge of silvicultural techniques for hydrogeological protection, forest fire prevention, biodiversity conservation and climate change mitigation.


The modules can be tested independently of each other. The final mark is the arithmetic mean of the marks of the two modules, rounded up. The 30 cum laude is worth 33 points.
