Oberrhein / Rhin Supérieur

Oberrhein / Rhin supérieur. 28/08/08; Baden-Württemberg; 25,117 ha; TRS centre 48°25_N 007°45_E. IBA, Natura 2000, Nature Reserve. The site includes 190km of the eastern bank of the river Rhine, with a variety of different natural and humanmade habitats and including at least ten zones of protection for birds. This alluvial area is very important for recharging one of the biggest aquifer in Europe. The site supports an outstanding number of relict, endangered and rare flora and fauna species, of which some cannot be observed anywhere else in Germany. An average of 92000 migratory birds stop here every year, and 46 fish species are supported. The site is also the last refuge for some sub-Mediterranean species, such as wild bees (Andrena chrysopus, Andrena marginata and Tetralonia salicariae), dragonflies (Aeshna affinis), and butterflies (Chamaesphecia aerifrons, Cucullia caninae, Luperina dumerilii, Meganola togatulalis et Synansphecia affini.) Navigation, water sports, agriculture, fishing and hunting are only few of the main land uses. Pesticides, fertilizers and mismanagement of the water resources could lead to very negative effects. Ramsar site no. 1809. Most recent RIS information: 2008.
