Information / Presentation

The Island, its heritage, its environments
During the 19th century, the island consisted of a garden around a villa and agricultural land. The garden was made up of an orchard, a French-style garden and an Anglo-Chinese style garden (marked by a bandstand).
To the north of the island the agricultural land consisted of a meadow, plantations of trees and a lake. The island was an agricultural exploitation. It is rich with many protected species including the fritillary or the marsh euphorbia. As time passed, the vegetation was changed greatly by the creation of a poplar plantation which was recently harvested as part of a restoration project of the island started in 2005.
To get to the island there is a footbridge. Visitors will find pleasant spaces as well as the magnificent trees in the park. The northern part of the island, which is covered in alluvial forest typical of the Saône valley, provides many different environments and species that are linked to the presence of water, with ponds, and damp hollows made in the sandy soil of the banks, which are created from the alluvial deposits left by the flooding of the two rivers, the Saône and the Doubs.
The island is divided into different parts:
  • La Clairière: a traditional garden... Situated at the entrance to the island, it is an area organised and developed to receive the public. The ornamental trees, as well as the local species from the island’s past, have been preserved. Look for and listen to; the jay, the tree creeper and the tits.
  • Natural water meadow: returned to its natural state following the harvesting of the poplar plantation, this meadow represents a great botanical diversity. Considered a favoured habitat, the island contains a variety of wildlife made up of different species of bird (crow, rooks, tits...) small mammals, amphibians and many insects, dragonflies and butterflies...
  • Riparian zone of the banks of the Saône:  this is where the land and aquatic zones meet, and consists of the vegetation that has grown on gently sloping sandy banks which plays an important role at the centre of the ecosystems. It also protects the banks from erosion.
  • The Negundo Maple: originally from North America and used as an ornamental tree, it has established itself in an invasive manner in the forests bordering rivers. Like the Black Locust, Japanese Knotweed, Buddleia or the Staghorn Sumac, the Negundo Maple is a species that constitutes a threat to the local ecosystem.
  • The alluvial forest zone: This alluvial forest is typical of the Saône valley and is made up of a variety of tree species, for example Pedunculate Oak, Ash, Elm and Alders. These woods are also home to abundant fauna with many different birds and insects to observe. This zone remains an area untouched by human intervention.
  • The wetlands: This zone has developed on the north cove of the island and offers a favoured feeding place for a range of waders and mud dwellers nesting or migrating with the presence of ducks and egrets. There is also a notable diversity of ground beetles. The wetlands offer a great ecological diversity, and are in peril from the closure of this place.
  • The pond: This small ecosystem is a site of reproduction and a habitat for different amphibians. It is the only standing water on the island, characterised by the formation of the duck weeds Lemna Minor and Spirodela Polyrhiza. It participates in the diversity of habitats. 
Information for Visitors:
The island is open to the public all year round except during flood periods.
For your security, do not visit the island during floods, do not walk on the banks and please remain on the pathways marked with wooden barriers. Unaccompanied children are not allowed on the island.
