NATURAL HERITAGE: THE REGIONAL NATURAL RESERVE OF L'ÉTANG DE HAUTE-JARRIE is located on the Champagnier plateau. Occupying 10 ha, it comprises a small natural lake of glacial origin, wooded islands, a reedbed and surrounding wet meadows. As far as birds are concerned, 150 species have been recorded on the site, including presti-gious nesters such as the Little Bittern, the Red-winged Warbler and the Purple Heron. In the axis of the Alpine furrow, the pond is also a regular stopover for numerous migratory and wintering birds: common teal, common snipe, harrier, great egret and whiskered tern. The peripheral wet meadows are home to the discreet, nationally protected gratiola officinalis, water germander and common pigamon. Small bladderwort floats in the open water. Rare dragonflies and butterflies can be found above or in the adjoining meadows. Herpetology is no less interesting, with eight species of reptiles and amphibians.
