Fauna and nature
Comacchio Valleys were born around the tenth century due to the lowering of the soil and the silting of the coastal area. The territory currently extends to more than 13,000 hectares, from Comacchio to the Reno River. This lagoon and marsh area covers four valleys: Lido Magnavacca, Fossa di Porto, Campo and Fattibello.
A few kilometres northern, in Comacchio territory, there is the Valle Bertuzzi. The valleys are among the most extensive wetlands in Italy.
The presence of water and degree of salinity make Comacchio Valleys a unique area extremely rich in food for the animals, so as to accommodate the largest variety of species in Italy (about 300).
It is easy to spot the Great Crested Grebe; the Black-Headed Gull, the Slender-Billed Gull, the Red-Billed Chough and the Sandwich Tern, the Greater Scaup and the Common Shelduck; the Black-Winged Stilt, in addition to the Collared Pratincole, which is very rare; Ducks and Coots (about one third of those surveyed in Italy), the Mallard and the Common Pochard (75% of the specimens); birds of prey include the Western Marsh Harrier and the Montagu's Harrier; the Great White Heron, the Grey Heron, the Little Egret and the Purple Heron. As the valleys are rich in fish, the Great Cormorant cannot miss.
Among all these species, the valleys have been enriched by the presence of pink flamingos, which stay in the near salt pan: in 1998 more than 400 specimens have been counted.
The valley is the ideal place to practice fish farming during the passage from the sea to the backcountry: The fishing protagonist in Comacchio is with no doubt the eel, captured with an unique instrument called “lavoriero”, but there are also basses (or seabasses), soles , mullets and breams. The high salinity makes life difficult for the flora in the valleys. Thus, the flora of the valleys is very different from that of the surrounding territories. Algae grow on these muddy and sandy seabeds (Sea lettuce and Valonia) and in the bumps you commonly find Salicornia, which in the autumn assumes the typical deep red colour, Salsola, which is edible and from which soda is extracted by burning, the Juncus Maritimus, the Oaks, the Stone Pines, the Beeches, the Reeds, the Tamarisk and the Limonium.
The valleys are privileged places for walks along the banks, boat trips and birdwatching.
