Hiking trail: Discovery Trail

Dominated by callune, mullein and birch, with peat bogs and ponds. A refuge for highly specific flora and fauna: amphibians, great crested newts and tree frogs. A signposted discovery trail leads around it.After the last ice age, the water remained in a kind of basin, allowing the formation of this 17-hectare environment. The Oignons peat moor in Boz is similar to an acidic peat bog, an original environment in the region and at this altitude of 200 meters. Dominated by callune, mullein and birch, it comprises a peat bog and pools. This environment is a refuge for a highly specific fauna and flora: amphibians are right at home here, and some species are protected, such as the great crested newt and the tree frog. Notable species observed: Flora: flooded lycopod (protected), round-leaved sundew (protected), marsh chickweed (protected), white rhynchophore (protected)... Fauna: mountain avens, green tree frog (protected), natterjack toad (protected) and stump lizard (protected). A discovery trail is available for all! The Oignons peat moor was awarded the "ENS" label by the Département de l'Ain in 2015. True natural and landscaped jewels of the Ain department, sites awarded the ENS "Espaces naturels sensibles" label are managed in such a way as to preserve the biodiversity they host, and developed for opening to the public (barring exceptions due to the fragility of the environments).
