Viverone
A Protected Natural Treasure
Welcome to Lake Viverone, the largest of the intermorenic basins of the Morainic Amphitheatre of Ivrea.
This lakeside environment is a Site of Community Importance (SIC) and an Area of Special protection (SPA), recognised and protected by the European Union for its high nature value.
The lake is famous for its extraordinary biodiversity:
• It is one of the most important areas at regional level for aquatic avifauna, acting as a crucial habitat for stopping, migrating and nesting birds.
• In about 30 years of monitoring, as many as 27 different species of geese and ducks have been recorded, a remarkable fact that elects this basin a ‘Birdwatching paradise’.
• Its shores, in particular the western shore: the most natural and least anthropized part – host extensive reed beds and wooded areas with black alder. These wetlands are a refuge for rare species, including the Lataste frog and the vicena butterfly of the swamps.
In addition to these riches, Lake Viverone is also site of a Bronze Age pile-dwelling site, included in the World Heritage SiteUNESCO.
We invite you to explore the Viverone with a Conscious approach: future development choices are oriented towards alternative tourism and a more respectful use of the delicate balance of lake habitats, essential for the conservation of its precious naturalistic value
Origin and Landscape
The Lake of Viverone is the largest of the intermorenic basins in the area. Its origin is linked to the retreat of the Balteo glacier, and is located at theinterior of the suggestive Morenic Amphitheatre of Ivrea.
The lake is located on horseback between the Provinces of Biella, Turin and Vercelli, On its banks are the municipalities of Azeglio, Borgomasino, Piverone and Viverone.
This landscape is not only characterised by water, but also by important vegetation: in the north-west there is a large wooded area where black alder prevails in the wettest areas.
In addition to natural wealth, the territory also guards Precious testimonies of the past: the submerged remains of a Bronze Age village, a pile-dwelling site included in the UNESCO World Heritage Site.
Habitat and Biodiversity
Lake Viverone is an ecosystem of high natural value, recognised and protected by the European Union as a Site of Community Importance (SCI) and a Special Protection Area (SPA).
The alternation of wetlands and wooded areas creates an environment conducive to a surprising wealth of life.
Flora and Rare Amphibians
• Terrestrial and Palustrial habitats: The north-western sector has a large wooded area where black alder prevails in the wettest areas. The western shore, the most natural and least anthropized part of the lake, is home to vast reed beds that form a complex mosaic with shrubs of gray willow and black alder.
• Aquatic Flora: In the deepest areas (up to 4-5 m) there are populations of aquatic plants rooted on the bottom with floating leaves, such as the yellow water lily, and submerged, such as the myriophyll and the ceratophyll.
• Protected species: Wetlands are vital for many species of amphibians, including the common toad, the dotted newt, the frog and the very rare Lataste frog. In addition, these areas are frequented by many species of dragonflies and butterflies, including the vicena of the swamps, of high interest at European level.
Avifauna and Birdwatching
The lake is one of the most important areas at regional level for aquatic avifauna. The site is a crucial habitat for the wintering, migration and nesting of waterfowl.
- Wintering and nesting species: In about 30 years of monitoring, 27 different species of geese and ducks have been recorded. This large number elects the basin as a ‘birdwatching paradise’. Among the nesting birds there are the major vassal (with about 30 pairs), the mallard and the coot.
- Rarity: In winter, rare specimens such as the fish, a duck that comes from Northern Europe and is very rare in Italy, can be seen. Luckily, it is possible to observe all five vassal species that live in Europe, including the very rare horned vassal.
- Elusive birds: In the swampy areas, the reed beds give shelter to birds such as the cannareccione and the cannaiola, which despite being very difficult to see, are heard with the song.

Protection and Environment
Despite the enormous wealth, the lake is a delicate environment, exposed to phenomena of strong environmental pressure.
Alien species: Accidental or voluntary introduction of invasive alien species is a major impact, as they compete with local ones. For example, the red shrimp of Louisiana is a real scourge for amphibians, and fish of North American origin have modified the fish fauna.
Indigenous species: Indigenous species such as perch and pike are still present in the lake, although pike is threatened by the introduction of the daubian log pike.
The preservation of its naturalistic value is essential for the future of the lake.
