abstract

The vegetation of “Serranella Lake” Regional Natural Reserve (Abruzzo-Italy). The “Serranella Lake” Regional Natural Reserve is about 500 ha wide. It’s constituted by an artificial bacin at the confluence between Aventino river and Gogna stream with Sangro river and by short stretches of them, in Chieti Province.
From a geological point of view, the river bed is characterised by Olocenic-Upper Pleistocenic gravely-sandy fluvial dregs; the terraces are constituted by platform clays while over them there are Pleistocenic-Upper Pliocenic sands and pudding-stones.
The phytosociological study, carried out on perilacustral, perifluvial and aquatic environments, has brought to the identification of 27 associations and plant communities, belonging to the following vegetational types: pleustophytic (Lemnetalia minoris); rhizophytic (Potametea pectinati); marshy (Phragmitetalia, Magnocaricetalia); nitrophilous therophytic (Bidentetalia tripartitae); hygrophilous therophytic (Cyperetalia fusci); herbaceous perennial of mineral wet and flooded soils (Plantaginetalia majoris, Agrostietalia stoloniferae); nitrophilous riparian (Calystegietalia sepium); riparian woody (Salicetalia purpureae, Populetalia albae).
Among the several associations, Zannichellietum palustris is reported for the first time in the Abruzzo Region, Typhetum laxmanni has here its most southerly station in Italy and other ones, as Scirpetum tabernaemontani, are very rare in the regional territory.
