Some headwaters of tributaries of the Great Enz and the headwaters of the Kaltenbach flow partly through Rastatt. Until the great territorial upheavals around 1803 and 1806, the course of the Enz ran mainly through the territory of Old Württemberg, with short sections in the Old Baden or through knightly estates. Wildbad, Neuenbürg, Vaihingen, Bietigheim and Besigheim were Old Württemberg centres of administration. The current territory of the counties of Rastatt and the Enz around Pforzheim (parishes of Brötzingen, Pforzheim, Eutingen and Niefern) belonged to Baden. In Oberriexingen, sovereignty was divided between imperial knights and Württemberg. Environment and economy Flora and fauna The lower reaches of the Enz, with their typical water meadow shore structures, are an ideal habitat for many riparian plant and animal species. Many of the oxbow lakes and riparian woodlands are protected habitats; the Enz itself and parts of the valley such as the nature reserve near Vaihingen-Roßwag and the mouth of the Leudelsbach at Unterriexingen are part of the Europe-wide protected network of nature protection areas known as Natura 2000. In the shallow waters up to 10,000 larvae - of mayflies, caddis flies, dragonflies, beetles, snails and mussels - have been counted. Even Western vairone, barbel, nase and bullhead have their spawning grounds here. From early summer, the Enz is home to dense communities of river water crowfoot and watermilfoil. Some rare and endangered species live all year round on the Enz, which is an important resting stop for many migratory birds. These include, inter alia, kingfisher, sandpiper, goosander, grey wagtail, moorhen and dipper.
