Description
The final stretch of the river Stella has no embankments and flows through a large reed bed until it reaches a group of casoni near the former mouth of the river. At the present time, most of the water flows into the lagoon through the “verto grando”, a man-made opening enabling the Cialisa channel to flow into the river without following the meanderings of its original course. With the river flowing through its centre, the peninsula is a rare example of an unspoilt natural environment, with a wide range of vegetation and animal life, but unfortunately the influx of the sea has had a powerful impact, eliminating the reed beds and drastically reducing the niche vegetation. Two scales can be seen near the Fraida water pump, which services the reclaimed land near Piancada, among reeds and strips of riparian woodland.
