Réserve naturelle nationale de la haute-chaîne du Jura
Réserve naturelle nationale de la haute-chaîne du Jura, National nature reserve in Eastern France.
The protected area extends over 10,909 hectares across 18 towns, from the Franco-Swiss border to the Rhône gap, with elevations reaching 1,720 meters.
The reserve's landscape formed through tectonic movements during the Alpine orogeny and subsequent glacial erosion processes approximately 20,000 years ago.
The reserve maintains traditional mountain farming practices through regulated grazing activities that help preserve the high-altitude grasslands and local biodiversity.
Visitors can access marked trails throughout the year, with entrance points from several towns including Gex, Divonne-les-Bains, and Thoiry.
The area contains 950 flowering plant species and serves as a habitat for 209 vertebrate species, including golden eagles and lynx.
