NATURAL HERITAGE: THE REGIONAL NATURAL RESERVE OF THE POND OF HAUTE-JARRIE is located on the plateau of Champagnier. Occupying 10 ha, it consists of a small natural lake of glacial origin, wooded islands, a reed bed and peripheral wet meadows. For the birds, 150 species have been counted on the site, among which are some prestigious nesting birds: little bittern, turd fox or purple heron. In the axis of the alpine furrow, the pond is also a regular stopover for many migrants and winterers: common teal, common snipe, harriers, great egret, moustac tern. The peripheral wet meadows are home to the discreet nationally protected gratiola officinalis, the water germander and the common pigamon. In the open water, the small bladderwort floats. Above or in the adjacent meadows, one can discover rare dragonflies and butterflies. The herpetological interest is not less with eight species of reptiles and amphibians.
