Course Content (Syllabus)
Development of phytosociology and its importance as part of Geobotany. Tasks of phytosociology. Plant communities. Sample plots (selection, sampling time and iteration, shape and size of plots). Sampling vegetation plots (general principles, scaling the cover-abundance of plants, determining the vitality, the sociability, frequency of occurrence). Growth forms. Overview of potential vegetation division systems (division systems based on vegetation stand features , division based on features irrelevant to the present vegetation stands). Division of vegetation based on physiognomic criteria (formation, Synousie). Division of vegetation based on floristic criteria: division according to the predominant species (association, Gajander forest types), division according to groups of plants [tasks and purpose of processing tables, example of table processing, Braun-Blanquet phytosociological approach (division and nomenclature of vegetation units, characteristic species, differential species), geographically distinct vegetation units, division of vegetation based on phytosocial groups, similarity indices of vegetation plots], division of vegetation independent of statistically obtained groups of species [division by ecological groups, division by chorological groups, dynamic - genetic classification of vegetation (classification based on succession, classification based on the final climax association, classification based on evolutionary types)]. Forest vegetation zones in Greece and their classification. Thermomediterranean vegetation zone (Quercetalia ilicis), Paramediterranean vegetation zone (Quercetalia pubescentis), Zone of beech, beech-fir and mountainous paramediterranean coniferous forests (Fagetalia), Zone of psychrobious (cold resistant) conifers (Vaccinio - Piceetalia), Non-forested zone of high mountains (Astragalo - Acantholimonetalia). Synchorology (Vegetation mapping, Vegetation profile, geographical distribution of plant communities). Applications of phytosociology.
