Learning Objectives
Knowledge acquired: concepts and methods for the typological and ecological study of the forest vegetation and the analysis of plant diversity. Better knowledge of the herbaceous flora of the Italian woodlands and the ecological value of bioindicator taxa. Use of quantitative methods for the study of plant diversity and identification of forest community types on a floristic-ecological basis. Use of quantitative methods for the analysis of biodiversity in forest communities. Knowledge of the most important types of Italian woodlands in terms of structure, syntaxonomy, biodiversity, dynamic role, conservation importance and other functions.
Competence acquired (at the end of the course):
Methodologies for the analysis of the forest vegetation and their application in different environments. Use of the phytosociological approach and multivariate techniques of data analysis. Identification of understorey flora of Italian woodlands and of selected bioindicator taxa.
Knowledge of the main Italian forest types.
Skills acquired (at the end of the course):
Capacity to plan and develop typological and ecological studies of woodlands from field sampling to data analysis using statistical techniques. Capacity to recognize numerous herbaceous species of woodlands and to understand their ecological meaning. Capacity to identify the main forest types in Italy and to interpret their synecology, biodiversity, dynamic role, conservation importance and functions. Analysis of plant species diversity of forest communities. Evaluate the implications for forest diversity of various forms of forest management.

Course program
Diversity: general concepts. Scales and levels of biological diversity. Taxonomic diversity, functional diversity, community diversity. Alpha, beta and gamma diversity. General characters of the Italian forest flora; functional traits of forest trees (examples of European and Italian species). Flora and vegetation concepts. Potential and real vegetation. Diversity and Dynamics. Successions and climax. Examples of secondary successions in forest vegetation. Serial and catenal contacts. Physiognomical methods; structure, life and growth-forms. Phytosociology: concept of phytocoenose and association; plant community. The forest phytocoenose and its properties as a complex system. The syntaxonomical system: alliance, order, class. Character-species and their ecological meaning. Field sampling of the vegetation and the phytosociological relevè. Minimal area. Data analysis: basic multivariate techniques of classification and ordination of the vegetation plots.
Analysis of alpha and beta diversity with quantitative methods and indices (Shannon and others). Ecological role of the herbaceous and understory flora and interactions with trees. Qualitative aspects of biodiversity (rare and vulnerable species, etc); taxonomic singularity and distinctness, phylogenetic diversity, examples and applications. The functional significance of forest biodiversity: relationships between diversity and main ecosystem functions, productivity and stability.
Survey of the most important forest types in Europe. The EUNIS classification system. Syntaxonomy, synecology and biodiversity of the main types of Italian woodlands.
