Mouth of Po di Volano

 


 

The environment

 

The identified area includes the area of the mouth of Po di Volano from the Volano bridge to the outlet into Sacca di Goro, the area called Peschiere and what is left of the southern part of the former Falce valley. The mouth of Po di Volano is divided into two parts, both directed to the North- East, towards the internal part of Sacca di Goro. The eastern part has been recently separated from Volano and divided into segments,  with precarious intercommunications. The Western part is the mouth that is currently active and which laps on Peschiere with its Eastern shore. Peschiere is a salty swamp in direct contact with the sea in the area of Taglio della Falce. Taglio della Falce consists of a marine inlet  that is located immediately North from the mouth of Volano and which delimits the Mesola wood at the South. It is the lagoon mouth through which the Giralda Valley (reclaimed in 1960) and the Falce Valley (dried up in 1969) communicated with Sacca di Goro and with the sea. The drying up of the Falce Valley caused a strong fall in ground water level and subsequently the death of the oldest specimens of the adjacent Mesola wood. This swamp (together with two other small ponds that are adjacent to the Caneviè Valley) makes up the wildlife sanctuary of  “Foce Volano” (mouth of Volano). Usually the water has quite low salinity levels because, despite the fact that the area communicates with the mouth of Sacca di Goro on the sea, it is strongly affected by the intake of fresh water from Po di Volano (Bondesan in Corbetta 1990).

 

The flora

 

The mouth of Po di Volano, Peschiere and Taglio della Falce are characterized by a halophylous reed bed with Phragmites australis and few open water areas, there are also prairies with Ruppia cirrhosa. In the area on the border with Taglio della Falce there is a salty meadow with Juncus maritimus (synt. Puccinellio festuciformis-Juncetum maritimi), accompanied by Aster tripolium, Limomnium serotinum, Puccinellia palustris and a small thermophilic brushwood (synt. Quercion ilicis), mainly characterized by holm oaks (Quercus ilex), and by Phillyrea angustifolia, Asparagus acutifolius, Clematis flammula, Rubia peregrina, Ruscus aculeatus, Osyris alba and Rosa sempervirens, together with mesophilic species (Corticelli 1999, Pellizzari and Pagnoni 1998).

 

The fauna

 

In the reed beds of the mouth (Peschiere area) there is a colony of purple herons that is one of the most important ones in Italy (210 couples). Po di Volano is an important area for the run of the twaite shad (Alosa fallax ssp. nilotica). Besides, in the fresh water area there is a large population of roaches, and at the mouth there are Canestrini’s gobies and lagoon gobies.

The reed beds are also nesting areas for the marsh harrier (Costa 1998).

 

Visits

 

A tourist naturalistic route that is currently not subject to any type of management starts from the North-Eastern tip of Porticino, leading to the area that is South from Taglio delle Falce, going along Peschiere, down to the Volano bridge.

There is a cycle path on the bank, from Passo Pomposa to Torre della Finanza.
