Coisia can be explored through its landscapes, nature and history. The Ain is the most important river in the area’s water network; Lac de Coiselet lies upstream of Coisia. There are also wetlands, dry calcareous grasslands and tangible evidence of cultural and geological history. This gives you a range of themes to consider when planning a trip: bodies of water, habitats and species, and a vast span of time, from a 16th-century statue to dinosaur tracks.
River Landscapes and Wetlands
The Ain is the most important river in Coisia’s water network. Lac de Coiselet lies upstream of the village and adds a lake to the waterscape. More than 2.5 hectares of wetlands were created through the restoration of La Lône in Thoirette-Coisia. These features present different aspects: the Ain and Lac de Coiselet define the waterscape, while the wetlands are both the result of restoration and a distinct habitat. The ecological character of the area may continue to develop; the figure of more than 2.5 hectares describes the restoration outcome. Those interested in waterscapes will find more than just named bodies of water here: there is also the scale of a restored wetland area.
Habitats and Species
Coisia’s dry calcareous grasslands offer another perspective. In 2014, they were home to numerous animal and plant species, including notable plants, butterflies, grasshoppers, reptiles and birds. Alongside the newly created wetlands, the grasslands present a clear contrast between a dry calcareous site and a wet habitat. This distinction is a useful guide if you are choosing Coisia primarily for its nature: the focus is not only on bodies of water, but also on different habitat types and the diversity of animal and plant groups recorded there.
The aquatic habitats of Lac de Coiselet are also part of the Natura 2000 site. In 2014, they were among the rare natural habitats of European Community interest.
Cultural History and Dinosaur Tracks
Coisia’s cultural and geological connections can be understood through two tangible examples. The church in Coisia houses a 16th-century statue of Saint Peter. The site “Empreintes de dinosaures à Coisia” preserves dinosaur tracks that are approximately 148 million years old. These two examples point to very different timescales: the statue is a dated work of early modern art, while the tracks come from a geological past far earlier still. If you are looking for specific historical and geological reasons to choose a destination, these two sites set Coisia apart without reducing them to the same theme.
