Impluvium d'Evian. 15/09/08; Rhône-Alpes; 3,275 ha; 46°22'N 006°36'E. Natura 2000. Close to Lac Léman (Lake Geneva) near the border with Switzerland, the site is located in the heart of a plateau where the popular mineral waters of Evian have their origin as rainwater is absorbed in the soil. During the infiltration process it is purified and redistributed underground, feeding the aquifer. The site is composed of seasonal and permanent freshwater marshes, forested and non-forested peatlands, rivers and streams. Although the site does not support an outstanding number of species, it provides an important habitat for invertebrates, in particular for two butterfly species Coenonynpha tullia and Boloria aquilonaris whose populations are in decline every where else in the region. Liparis loeserii, a very rare orchid, is still well represented in the site. Urban development and water abstraction are possible threats for the maintenance of the hydrological balance of the site. Ramsar site no. 1833. Most recent RIS information: 2008.
