abstract

The vegetation of the terminal course of the Tiber River and of its affluents (Latium, Italy). The aquatic and riverbank vegetation of the Tiber River’s terminal course and of its main affluents (Treia, Farfa, Aniene) are described. The phytosociological approach is applied and, utilizing ecological and water chemical-physical analysis, it has been possible to define more accurately the synecology of macrophytes communities. This study allowed to identify thirty-one vegetational types, among which aquatic communities mainly belonged to classes Lemnetea minoris and Potametea pectinati, bank macrophyte types to Phragmito-Magnocaricetea and, in conditions of higher human disturbance, to Bidentetea tripartitae. The woody riparian vegetation has been included in Salicetea purpureae and Querco-Fagetea.
